Dairy May Cause Rather Than Prevent Osteoporosis 

I'm inclined to come right out and say: Forget what you've read in the popular media about dairy, calcium, and osteoporosis. It's inaccurate and may dangerously—if not irresponsibly—lead you down the wrong path.

You've probably heard a thousand times how it's important to consume dairy to have strong bones and reduce your risk of osteoporosis. But the science doesn't support this. Too many studies suggest that dairy is more likely to contribute to osteoporosis rather than prevent it.

Let's look at a few recent studies which show what does and does not work in terms of protecting and strengthening bones:

...

Men who consumed the most fruit, vegetables, and cereal had denser bones than those who consumed less, according to a Tufts University study of volunteers aged 69 to 93.
American Journal of Clinical Nutrition, 2002

80 white females, aged 12 to 22, were studied for ten years as part of the Penn State Young Women's Health Study. Daily calcium intake varied from 500 to 1,900 mg, but only exercise was identified as a predominant determinant of bone strength. (Girls develop 40 to 50 percent of their skeletal mass during their teen years.)
Journal of Pediatrics, 2004

The Harvard Nurses' Health Study of 72,000 postmenopausal women showed that neither milk nor a high-calcium diet reduce fracture rates at all in 18 years of follow-up. Adequate intake of vitamin D, on the other hand,was associated with a lower rate of osteporatic hip fractures. Skin exposure to sunlight can serve as a major source of vitamin D. Note that the vitamin D in cow's milk is an add-in just as it is with nondairy milks.
American Journal of Clinical Nutrition, 2003

...

Next, let's look at some populations around the world to see if there is any evidence that consuming dairy products confers some sort of protection against osteoporosis and bone fractures.

Dr. Robert M. Kradjian, Breast Surgery Chief of California's Seton Medical Center sums up what other independent researchers (unaffiliated with the dairy industry) have found: "[C]ountries with the highest intake of dairy products are invariably the countries with the most osteoporosis." The United States is near the top of the list in both per capita dairy consumption and prevalence of osteoporosis. American women have one of the world's highest rates of hip fractures, which is often used as a reliable indicator of osteoporosis. The populations of many Asian countries consume very little dairy and have a far lower rate of bone fractures than that of Americans. China is relatively dairy-free and has among the lowest incidences of osteoporosis. As mentioned above, the huge Harvard Nurses' study showed no evidence that dairy products offer any protection against osteoporosis. In fact, the volunteers who consumed the most dairy foods broke the most bones.

So dairy seems to be of no help in guarding against weak bones and osteoporosis. Later in this post, we'll find out why, and then delve into how consumption of dairy probably worsens bone health. But in the meantime...What about calcium supplements—are those helpful?

In the Penn State study cited above, researchers found that, consistent with past studies, calcium intake above 900 mg a day had no lasting effect on bone health. Regular exercise did. The government's daily calcium recommendation for women aged 9 through 18 (which covers most of the age span of the volunteers in the study) is 1300mg per day, and 1000 mg per day for ages 19 through 50.

The 36,282 postmenopausal participants in the Women's Health Initiative clinical trial were given either a 500 mg calcium supplement or a placebo. Although the group taking the supplement had a 12 percent lower rate of hip fractures, their rate of total fractures was the same as the group taking the placebo. The supplementation group also had a 17 percent increase in kidney stones.
English Journal of Medicine, 2006

From these and similar studies, my conclusions, which I earnestly try to follow for my own diet, are:
A little more about point 2...A number of studies show that consistently high levels of calcium intake interfere with the body's ability to effectively use calcium. Also, a recent study presented at a meeting of the American Society of Nutrition correlated high levels of calcium intake with cognitive impairment in the elderly.

Next, I want to get into the heart of this post, showing how animal protein intake significantly increases one's risk of osteoporosis and raises one's calcium requirements.

Getting Used to New Foods 

Jane's comment in the last post got to me thinking... There may be three reasons (at least) why we don't like a food that's new to us:

  1. Some foods we just don't like. For instance, I've never liked Brussels sprouts. (I conveniently left them out of the vegetable section of this series.)

  2. The quality isn't very good. For instance, the general consensus is that veggie dogs from 10 years ago generally were not very tasty, they're much better today, but will be noticeably improved 10 years from now.

  3. We're not used to it. This is what I want to talk about some more.
A typical breakfast in the U.S is much different than the typical breakfast in Japan or India or Mexico. Say you were on a business trip in Chicago. Your hotel breakfast menu has an entree for fried noodles and bean sprouts, with a barley drink to wash it down. Would you order it for breakfast? Probably not if you're a typical American. If you were Malaysian, it would seem just fine. If that's all they had for breakfast (maybe you were staying at a family-run bed and breakfast), and you were a typical American (or probably even an atypical American) you might eat it, but by the fourth day you would likely be longing for some Cheerios. Or hash browns. Or pancakes—something familiar.

It's not that one breakfast is better than other. It's what you're used to. If you moved across the world and started eating the foods that are typical for that region, after a while you'd probably develop a taste for them. They would start to feel more natural. You'd eventually develop favorite native dishes and look forward to them. You'd probably make this adjustment much more easily if you were young. If you were a toddler, the switch might be effortless; you might even like the new cuisine better. (When my niece was two, she was in a small home-run day care facility where they served Persian food to the kids. She took to it right away; in fact, she even asked for it at home!)

All this is to say that when switching to a) meat substitutes, b) a more vegetable-centered diet, give your body—if not your mind—some time to adjust. A plant-based meat substitute might taste inferior at first, but after a while it may very well taste great and get you to salivating. It's not just a case of settling for something second-rate; I think your taste buds and probably other parts of your body chemistry get bonded—like memory foam—to certain types of foods and cuisines if you have them frequently enough, over a long period. In fact, some foods, such as cheese and chocolate, are known to be physically addictive, so your body and mind may have temporary withdrawal symptoms if you give them up. But after a while everything recalibrates and you're in tune with your new diet. (But don't give up dark chocolate!)

This doesn't mean that you'll like every new food you try. But unless you really can't stand a new item, or new family of foods, give it a few tries over a month or more and you may find that first impressions can be deceiving. Also, experiment with various styles of preparation—different spices or cooking methods, and so forth; that may significantly alter the taste and your satisfaction level for the food.

Regarding vegetables specifically, you may want to let your current tastes be a guide to which new vegetables to try first. If you like collard greens, you'll probably like kale. If you like cabbage, you'll probably like bok choy.

Two more things.

A typical Western-style meat-centric meal is often exceedingly high in saturated fat and calories. It overwhelms our bodies. We don't have the digestive system of a real carnivore. We don't have the strong stomach acids and quick processing action to efficiently break down uric acid and other ingredients in meat. We don't sleep half the day like cats and lions. We may come to accept that after a big dinner, feeling sleepy and needing a shot of caffeine is just normal, and in time our bodies and possibly our minds may crave that. But that's so arbitrary. Although you can make any vegan meal full of fat and calories, I would advise getting used to feeling slightly less full. Lighten the load a bit. Yes, you'll get hungrier sooner. Nothing wrong with that. After a while, you won't have the physical or psychological need to eat twice as much as you should have, and to commiserate with your fellow eaters about how full you are and about how you should have worn pants with an elastic waistband and so forth. Save those indulgences for special occasions.

Lastly, I hope that knowing that you are not contributing to the horrors of slaughterhouses becomes a life-long motivation for eating a plant-based diet. I believe that feeling good about your food choices, with no need to hide the cruelty of its sources from yourself or engage in never-quite-satisfying rationalizations, not only eases your mind but improves your digestion. And I think it makes food taste better.

Next: The series continues with a sure-fire meat substitute. I've got a crisp 20 that says if you are a meat-eater and were served this product at random, without having had this discussion first, it would not even cross your mind that it was made from plants.

To be continued...

[Addendum: I thought of a fourth reason why people may not like a certain food, particularly a vegan substitute food, and I think that merits some discussion also. I'll cover that in the next post.]

Fiber Fact (Plus Commentary, Probing Questions, and Motivational Talk) 

The American Heart Association and the National Cancer Institute each recommend at least 25 grams of fiber daily. On average, Americans only get half that amount in their diets.

That's a serious deficit.

Now step back a minute. How much do we spend looking for a cure for heart disease, cancer, and diabetes? Billions when you add it all up. What are our medical bills from those diseases? How much do we lose in productivity when people are stricken with these diseases? How much do we spend on long-term care? What about the emotional toll on patients and their families?

According to repeated studies in respected journals, we might cut our risk for those diseases—at least some forms of those disease—by roughly up to a third, simply by switching to a fiber-rich diet as recommended by nearly every health and medical group in the country (probably the entire world). The bottom-line net cost for this powerful preventive measure: zero.

You get fiber from a variety of plant-based foods, including whole grains, and they're as close as your grocery store shelves or local farmers market.

Why isn't the National Institutes of Health (NIH) studying ways to get people to increase their fiber intake? Maybe because there's no prestige in it?

Overwhelmingly, the commercials during prime time are for appallingly unhealthy, low-fiber foods, such as fried chicken, pepperoni pizza, and bacon cheeseburgers. The purveyors of these products know that high-fat, high-salt food is tempting, especially when they present it in the most tantalizing and inviting ways possible. You better believe they spend no small amount of time and money carefully crafting every image, every action by every actor in the commercial—everything; they want you hooked, regardless of what it might do to your health. In between these commercials are a flood of spots for drugs: heartburn pills, weight loss formulas, high blood pressure medications, you name it—conditions that may come about from eating an unhealthy, low-fiber diet. They've got you coming and going. Why doesn't the USDA or NIH promote fruits, vegetables, and whole grains during prime time, and tout these foods' heart disease-, cancer-, and diabetes-fighting potential?

Well, you don't have to wait for the government to change its policies. You can start increasing your intake of fiber-rich foods immediately. Did I say the net cost was zero? I was wrong. It's probably way less than zero once you consider that you'll probably have a much lower outlay for long-term meds and hospital procedures. And the side-effects of more fruits, vegetables, whole grains and legumes in your diet are almost exclusively positive ones, such as more energy, lower blood pressure, improved regularity, weight loss, and overall better health. It's a no-brainer!

I hope the tips in this series for increasing your intake of high-fiber foods help you integrate these natural miracles and potential life-savers into your daily lifestyle.

Here are a couple of tools to help you approximate your individual daily fiber needs and daily fiber intake:

Daily Fiber Intake Requirement
Figure out how much fiber you need per day, roughly (no pun intended).

Fiber Content of Common Foods
Estimate your actual daily fiber intake, in grams. For foods that aren't on the list, pick something close.

Two more tips when increasing your fiber intake:

  1. Do it gradually, to let your body adjust.

  2. Drink more water. Fiber is like a sponge.

Interview With Dino — Improvising in the Kitchen 101: Part 4 

There is a ton of information in this next installment of the interview...enjoy!

Gary: The next (and next to last) set of questions has to do with spices that most U.S. households are likely to have accumulated over the years, for one reason or another, even if no one does much cooking. I want to ask you if you have any simple ideas for using these spices. Again, just to limit the scope, I'd like to focus on vegetables primarily and fruits and grains secondarily, but if there is a "you must know about this" tip you'd like to share that doesn't fit into those categories, don't hold back!

OK, here goes...

Cayenne pepper or similar

Dino: Ever seen that lovely film called Chocolat? If not, go rent it now. The next time you make a cup of hot chocolate or coffee, throw in just a pinch of cayenne. You'll never be able to go back to the sickeningly sweet stuff that passes for good hot chocolate nowadays.

Barring that, there is no chilli recipe that would do without at least a pinch of cayenne. You need it for the fiery Southeast Asian cuisines of Thailand. In fact, to be honest, I find that cayenne is just a lovely addition to any sweet-and-sour combo, to offset the sweet. Say for instance, you're starting off with a mess of stir-fry vegetables, right? Suppose you start with some screaming hot peanut oil in a skillet, and add carrots, onions, peppers, bamboo shoots (from the tin; who has time to bother with fresh!?)
[I cut my own bamboo and slice it into shoots, but I digress —Gary (*)], scallions, sprouts, cabbage, and whatever other vegetable stirs (haha) your imagination. Suppose you add a healthy splash of tamari, or soy sauce. Suppose then, to offset the salty taste, you add in a healthy splash of orange juice. Then, to offset the sweetness, you add a very generous splash of lemon juice. When all is said and done, you're talking basic, yummy, and vibrantly coloured food. However, there are those of us who like a bit of adventure when we're eating stuff that we've probably had before.

Enter the cayenne.

Just a light sprinkle of cayenne, along with some crushed peanuts, will transport your stodgy stir-fry from back-alley fast food into an orgy of flavour. If you can possibly imagine a fiery edge to the next batch of stir-fry you pick up from your local Chinese fast food place (which typically runs on the sweeter and saltier side), you're sure to do like my mother does, and carry a batch of hot chili powder with you anywhere you go.


Gary: Chili powder

Dino: There is the spice blend that contains (amongst other spices): cumin, garlic powder, onion powder, coriander, some tiny trace of ground chili, and other spices. This is usually what I think of when I hear "chili Powder". It's the stuff you use when making ... well ... a chili! Starting with about a kilo of onions, a kilo of carrots, and 1/2 kilo of bell peppers, and a head of garlic is the perfect beginning to a good, strong chili. In the largest pot you have, heat up a few tablespoons of oil. You might need up to 1/4 of a cup of oil. Use a neutral flavoured oil, like canola, peanut, or safflower oil.

When the oil is hot, add the onions, carrots, peppers, and garlic. Drop down the flame to as medium, and allow the vegetable combination to cook for as long as it takes to get medium brown. You want the onions, garlic, and peppers chopped into a rough chop, and the garlic to be whole (for a milder garlic flavour), or minced (for a stronger garlic flavour). When the whole lot is the colour you desire, pitch in about 1 1/2 kilos of tinned, diced tomatoes, and a good handful of Chili powder. Turn up the heat to as high as it will go, and allow most of the water from the tomato tin to evaporate. Once you're down to about 1/4 of the original liquid from the tin, add a healthy slurp of tequila or dark rum. This step is optional. Add in about 3 kilos of cooked beans (as in, they weigh three kilos when you're done cooking them; start with about 1 1/2 kilos of dry beans to get to this level, or use tinned; both are equally fine). You can use all of one bean, like pinto, black, kidney, or pink beans, or combine them in any way you deem fit. You can omit the liquid from the tin, or add it in. It depends on your preference for how thick you like your chili.

Let the whole mess come to a full, rolling boil, and let it cook for about 10 more minutes. Add one ounce or so of unsweetened chocolate, or an ounce of cocoa powder (unsweetened). Let the whole lot cook for about 10 more minutes, and eat!

Barring that, chili powder is wonderful when sprinkled onto yams, yucca, sweet potatoes, squash, eggplant, chickpeas, potatoes, or any other hearty vegetable that you fancy. To prepare, simply mix 1 tablespoon of chili powder with 1 tablespoon of oil. Toss about 1 pound of your vegetable (or chickpeas, if you're feeling adventurous!) in the spice and oil mixture. Throw it in the microwave for about 10 - 15 minutes, or in the oven at 350° F for about 30 - 45 minutes. If it's a tough veggie, let it cook longer. You now have a quick and delicious entree to dump onto bread, rice, or pasta, or eat by itself.


Gary: Cinnamon

Dino: The reason that apples and cinnamon are a cliche is because the two of them work so well together. Barring that, the next time you make the chili recipe I mentioned, feel free to pitch in a teaspoon or so of cinnamon with the chili powder. Also, any time you do sweet potatoes with maple syrup, you have to add a healthy dose of cinnamon for the taste to come out clearly. My morning oatmeal would be incomplete without cinnamon, as would my coffee, and hot chocolate.

Gary: Garlic powder

Dino: I tend to reserve garlic powder for when I want to punch up a jarred pasta sauce. I'll throw some olive oil into a skillet, throw in the jarred pasta sauce, throw in a few shakes of garlic powder, and let the mess come together in about five minutes. When it's done, I'll dump in the fresh pasta, and the taste is just as if I've been slaving over a hot stove. Additionally, whenever I am sauteeing onions for a recipe, and the recipe doesn't call for garlic, I'll throw some garlic powder into the sautee, to punch up the overall taste. Ditto this on whenever I make a coconut cream sauce. I'll start with the traditional roux (1 TB of oil, 1 TB of flour, heat over low heat until light blond, then pitch in 1 cup of coconut milk, then add a pinch of nutmeg and garlic powder), and do my magic when the sauce forms.

Gary: Onion powder

Dino: Ew. Wait, people actually BUY this stuff? Ew. Just. Ew. The flavour is far inferior to garlic powder, and onions are cheap and readily available enough that this travesty of the spice world should really go crawl into some corner and die.

Gary: Oregano

Dino: Remember the pasta sauce example? Same here. Throw in some oregano to punch it up. Same with the chili powder example, where I mention adding 1 TB chili powder to 1 TB oil? Try throwing in oregano with those veggies. Also, any chile recipe will be complemented extremely well by oregano. Simply add it with the onions and garlic and peppers. Any recipe that calls for tomatoes will do well with oregano. Any recipe with root vegetables, but not a lot else will do well with oregano. The next time you make corn chowder, try some oregano in it; your tongue will thank you. Any bean recipe will love oregano. Crumble the dry leaves in your palm before you add it to your pot, so that you release the maximum flavour.

Gary: Parsley

Dino: Any time I have a sautee going, with onions, garlic, and/or other aromatics (carrots, peppers, etc), I add lots and lots of dried parsley if I have it. Just like oregano, crumble it in your palm before adding it in. Come to think of it, pretty darn near any savoury dish does well with a healthy (and I do mean healthy!) dose of dry parsley. I find that I need about a handful or so for the impact to come through in a pot of food meant for 4 - 6 people.

Gary: Not quite as ubiquitous, but still very common:

Basil

Dino: Always use wherever there are tomatoes present. Use generously in Thai food, or any other recipe which calls for hot ingredients, or creamy ingredients (like coconut or coconut milk).

Gary: Bay leaf

Dino: Never let a soup happen without some bay leaf in it. Ever. Bear in mind, however, that bay leaves are not digestible, and need to be removed before you serve the food. Also remember that bay leaves take some serious time to impart their flavours, so use it mainly in long-cooking curries, or soups, rather than quickie foods. Will do extremely well in my chili recipe, if you add it with the sauteeing aromatics.

Gary: Cumin

Dino: Always use cumin in chili, to punch up the "Mexican" flavour. Use with refried beans to give it flavour; often the stuff in the tin or from the restaurant is fairly boring. Use generously with any root vegetable. Use with any Indian dish.

If you have cumin seeds, you are especially lucky. The next time you make a savoury dish, start like the Indians do. In a large pot, heat up a tablespoon or so of oil. Sprinkle in 2 teaspoons of cumin seeds. Wait about 30 seconds or so, and your house will fill with the mouth-watering smell of cumin. The seeds will begin to jump and pop. Add about 2 cups of uncooked, long grain rice (or any other vegetable you feel like cooking). Drop down the heat to medium heat, and gently cook the grains of rice (or vegetable) until you smell a nutty aroma (or until the veggie is browned). Add in about 4 cups of water. Increase the heat to high heat, and allow the water to come to a full, rolling boil. Let the water boil for about two or three minutes. Slam on a tight-fitting lid (or aluminum foil, if you don't have the lid), and decrease the heat to as low as it will go. Set a timer for 25 minutes. After 25 minutes, turn off the heat, and remove the pot from the heat. Allow the rice (or vegetable) to rest for about 10 minutes. Uncover the pot, and dig in! It's fabulous. This same technique can be used to make split pea soup. Just add about 3 cups per cup of water, and skip the browning step.

Cumin has anti-gas properties, which is why Indians use the spice so generously whenever they make cruciferous vegetables (cabbage, cauliflower, broccoli), or beans.


Gary: Dill

Dino: To be honest, dill is one of those few herbs that I rarely use when it's dried, because the fresh and dried version are so different, that I tend to avoid the dried. When you have the fresh, it's perfect in salad, and other raw applications. Throw some onto sliced cucumbers, with a dash of lemon, for the best summer treat ever. Combine it with hummus for an unusual flavour combo. Have it with tomatoes, parsley, and lemon, and you'll never want cooked tomato again!

Dry dill, on the other hand, is a lot more sober, and subdued. I'd use it in any application where dry parsley is appropriate.


Gary: BBQ sauce

Dino: Use for dipping French cut fries, or slices of baked potato or baked sweet potato. Slather onto mature plantain, and bake in the oven for a smoky, sweet treat. Rub onto slices of eggplant, and grill. Use as a marinade for portabello mushrooms, and grill.

Gary: Soy sauce

Dino: Use in place of salt in recipes calling for salt. Switch to Tamari, if you're gluten free. Switch to low sodium, and see if you can really tell that much of a difference (why eat the extra salt if you don't have to!). Combine with various fruit juices, citrus, and/or spices to create your own marinades for various vegetables. When making tomato sauce, use a capful of soy sauce to counteract the tinny flavour of tinned tomato. When making a vegetable stock, add a few shakes to give the stock a much deeper, richer colour. Use for dipping of steamed vegetables.

Gary: Szechuan sauce or similar

Dino: It reminds me too much of snot to take it seriously. ::shudder::

Gary: Tabasco sauce or similar

Dino: Sriracha, Tabasco, and other fiery sauces should be on hand for those who like a bit of a kick with their food. Any time you do sweet-and-sour applications, have a touch of heat to offset the cloying sweetness that is so typical of the sweet and sour craze. Always have hot sauce on hand to combine with ketchup (and, in my house, freshly minced raw garlic) for a fabulous dipping sauce for French cut fries, and tater tots. (Yes, tater tots and other fried foods aren't healthy, but if you're having them, you might as well enjoy them, right!?) Add a fiery kick to your chili by adding a bit of hot sauce at the table, before you dig in to eat. If you're like my husband, you'll like to have it on pretty close to everything.

[Dino added a couple more common, useful spices to the list...]

Coriander powder:

For those who dislike, or are allergic to cumin, coriander powder is an ideal substitute. It's got the same smoky aroma, but a much more subtle flavour.

Sesame Seeds:

I would never let my kitchen exist without sesame seeds. I add them to hot oil before adding my aromatics (when I sautee aromatics). I add them to hot oil along with cumin seeds to release the flavour of both spices into the oil, before cooking vegetables. If I'm making (cooked) garbanzo beans, I always add a good dose of sesame seeds, paprika, and olive oil, before pitching the lot into the oven for 15 minutes (at 350° F). I could never dream of a soup, stew, or bean dish without some bit of sesame seeds. Because they're high in iron, I don't even feel guilty about the negligible extra fat they add.


Next: Some commentary on all this...plus we added one more small segment.

(*) kidding, of course.

Interview With Dino — Improvising in the Kitchen 101: Part 2 

The previous exchange raised some questions in my mind, plus I wanted to delve a litle further into how a beginner would experiment, cautiously, with spices. Without any further ado...

Gary: What kind of oil should I use?

Dino: The midnight oil, damnit! After using some of these techniques, you'll find yourself cooking less, and eating more. This is a good thing.

Seriously though. It depends on what you're doing. Say for example, you're adding garlic, onions, peppers, celery, carrots, or any combination (or any one of those) to cold oil, heating said oil and aromatics in a pan, and then adding other ingredients, you can use any cooking fat. What am I talking about? Frankly, fats have this wonderful way of only doing one thing rather well. For example, olive oil is really good at tasting buttery, and lending such a depth of flavour to whatever you eat. However, it's really bad at getting super duper hot. Try to set your stove on high with olive oil in the skillet, and you'll soon have a face full of smoke, and really nasty smelling living grounds. Instead, with olive oil, you add aromatics (garlic, onions, carrots, celery, etc.) to the cold oil, and set the pot on the heat. The aromatics have water, which prevents the oil from rising too much above the 212°F, which is the boiling point of water.

Mind you, this isn't a license to set the stuff on the stove and forget about it, but rather a nice insurance policy.

However, there are times when you want to really scorch the bottoms of your vegetables, and get some serious colour going. In these cases, you use an oil that can handle very high heats. Examples are canola, peanut, vegetable, and safflower oil. With these oils, you can set a pot on the stove, crank the heat up to high, add the oil, and add the aromatics, or whatever else to the pot at your (relative) leisure. You still need to act quickly, as you've got about a minute before your kitchen turns into a smoky mess, but the oil will resist the temptation to stay at the neat and pat 212°F. Instead, it will aggressively inch towards 500°F!

The point is that you want to suit the oil to your cooking situation.

HOWEVER! Don't feel afraid of starting canola, peanut, safflower, etc. oil off cold, with aromatics thrown in. Starting with cold oil, and cold aromatics, and allowing the two to come to temperature together, is a time-honoured method of withdrawing the maximum of flavour from the aromatics. Also, when you're baking or have everything ready, and you do the spice blend method, you really don't need to worry about which oil you use.

Let me handle the first scenario first. Suppose you are feeling infinitely lazy, and need to have a shower before dinner is served. You're smelling quite ribald, and feeling the need for the cleansing waters to relax. Get into your kitchen, and hack up some root vegetables to about the same sized chunks. In a small bowl, combine a couple of tablespoons of oil with your favourite spice blend, and a bit of salt and pepper. Make a loose paste of this. In a large roasting pan, combine the spice-oil mixture with the chopped vegetables. Toss the veggies with the spices and oil to combine everything evenly. Set the oven to 350, the timer to 35 minutes, and get on with your shower. By the time you get back, you'll have the kitchen smelling heavenly, and a large mess of vegetables, waiting to be served over salad greens, or in between two slices of bread. In this case, the oil doesn't matter, because you're mainly using it to be a vector for the spices, and the fact that the oven is slowly roasting your vegetables will keep the oil from burning. Frankly, the controlled temperatures are ideal for any oil.

The second scenario is if you have a quick hand, and everything waiting. Set your large stock pot onto the stove. Crank the heat up to high. Drizzle in whatever oil you choose. Wait about 20 seconds for the oil to heat. Immediately pitch in your aromatics. Because you've got everything waiting, you don't have to worry about the oil getting too hot too quickly. Otherwise, if you aren't that quick in the kitchen, follow the advice I originally gave.


Gary: What is sriracha, and can I find it in Nebraska?

Dino: It's one of those delicious fire sauces from Southeast Asia. If you can't find it in Nebraska, never be ashamed of substituting Tabasco, or whatever other hot sauce you fancy. If you don't fancy hot sauce, cheat, and add a touch of black pepper (as much as you can take!) to some ketchup, and call it a night. Nobody has to know.

Gary: How do I know if I've added enough spice? How do I prevent adding too much?

Dino: Eyeballing it works for me. If I'm looking at a piece of vegetable in the pot, and each piece has enough spice that about half of it is visible through the veil of spices, I'm good to go. If you've added too much, cheat, and pitch in some cooked pasta, potatoes, rice, or whatever other frozen vegetables you have lying around. To prevent adding too much in the first place, measure out just enough of whatever spice you're adding into the palm of your hand first. If it takes up more than a dime-sized round, you're probably going to end up with too much ... stuff in your food. Err on the side of not enough.
Worst comes to it, you can always sautee some more onions and garlic in oil, add additional spices to that pot, and mix it in with the rest of the food. Nobody has to know, and you've avoided the problems of having raw-tasting dried herbs.


Gary: If I add more than one spice, do I cut back on the amounts of each one?

Dino: Here's a rule that works for me. When I'm working with an unfamiliar spice, I'll first start with 1/2 teaspoon, and add the rest of the "normal" seasonings. For example, whenever I make a pasta sauce, I add: 1 tablespoon of Italian seasoning, 2 tablespoons of Mrs. Dash, and 5 cloves of garlic. However, I saw a recipe that used fennel seeds. I'm not sure how it'll work out in the end. Because I'm a bit nervous about a spice like fennel seeds, I'll even cut it back to 1/4 teaspoon, rather than 1/2 teaspoon. Chances are that it'll be so subtle that I won't even notice it (as I tend to make about a 6 lb tin's worth of diced tomatoes of sauce every time I bother to make sauce). If that slight hint is pleasant, I'll try to up the ante the next time. Eventually, I'll find an amount that's close enough to the new recipe to suit my tastes. Sometimes, I end up adding more. Most of the time, I add less than what others like. The point is that because I introduced it gently, I never jarred myself into dislike.

Gary: Adding OJ and lemonade is a nice touch! Do any other kinds of juice work? Pineapple? Apricot? Fruit punch?

Dino: YES! Yes! Not so much.

Pineapple juice is very easy to incorporate into different foods, because it's got a distinctly tropical feel.

Apricot juice tastes of Tradition, and Pomp. It's quite a sophisticated taste.

Fruit Punch, however, tastes of...red. I'm serious. What other flavour can you attribute to Fruit Punch? It's lovely with a hefty shot of vodka, and a splash of lime juice, but otherwise, it's best left to church picnics, with women who wear tragic parodies of fashions they saw in Better Homes and Gardens.

Frankly, I love Better Homes and Gardens, Fruit Punch, Vodka, and Apple Pie, too. However, I do feel that all of those things should be enjoyed in places where they will make the most impact.



Next: Some brief commentary on this round of Dino's information-packed replies.

Also: Later in the series, I actually plan on mentioning Better Homes and Gardens. You'll see...

More Motivations to Eat Your Fruits and Vegetables 

A 14-year study of 71,768 female nurses, aged 38 to 63, showed that, after controlling for lifestyle factors, those eating the most fruits, vegetables, whole grains, and low-fat foods had the greatest protection from stroke.
The Lancet, 2003

A study of 519,978 subjects in 10 European countries showed that individuals who consumed the most dietary fiber had a 40 percent reduction in colon cancer risk than those who consumed the least. Fiber is found in a range of plant-based foods, including fruits and vegetables.
The Lancet, 2003

A 17-year study of 29,564 women, aged 55-96 and initially free of cancer, showed that increasing fruits, vegetable, and plant foods, and limiting the intake of salt, additives, fat, and meat may significantly decrease cancer incidence and mortality.
Cancer Epidemiol Biomarkers Prev, 2004

A Harvard Medical School study of about 85,000 female nurses and about 32,000 male health professionals showed that men and women who consume the most magnesium were least likely to develop diabetes. Magnesium is found in beans, green vegetables, whole grains and nuts. The benefits of magnesium were still apparent after adjusting for age, family history, exercise, alcohol consumption, and other factors that may influence the disease.
Diabetes Care, 2004

A study of 1,230 men aged 40 to 64 showed that men who ate three or more servings of vegetables per day had a 48 percent lower risk of prostate cancer compared with those who ate less. Cruciferous vegetables such as cauliflower, broccoli had the strongest effect.
J Nat Can Ins, 2000

Canadian researchers analyzed dietary data for 585 people with pancreatic cancer and 4,779 people without the disease. After adjusting for age, smoking, body mass index, physical activity, Canadian province, education, and total calorie intake, researchers found that men consuming the greatest amount of fresh fruits and vegetables were half as likely to develop pancreatic cancer as men who consumed the least amount of these foods. For unknown reasons, the benefit of fruits and vegetables was limited to males. Note that pancreatic cancer has one of the lowest survival rates of all cancers.
Int J Cancer, 2005

A study of 77,000 women and 40,00 men showed that those who ate the most fruits had the lowest risk of macular degeneration.
Arch Opthalmol, 2004

Finally, this study, which is not directly about fruits and vegetables, but which I think is astounding:

Researchers studying 44,788 pairs of twins in Scandinavia concluded that genetics only plays a 27 percent role in determining whether one gets breast cancer, while the environmental and lifestyle component is 73 percent.
New England Journal of Medicine , 2000



Now, to get the most disease prevention benefit from your diet, you can't only add healthy foods. You also have to get rid of the culprits—mainly, meat, dairy, and fat. I'll deal with the first two of those foods later in this series, and the third factor (fats) over a longer period.

Motivations to Eat Your Fruits and Vegetables 

The other day, my sister-in-law said, "It's so hard to tell what's good for you and what's bad for you. Every day there's a new study that contradicts the previous one."

It's not quite that random or confusing. There are some patterns that are remarkably consistent, decade after decade. After perusing through studies on the effect of diet, it becomes abundantly, undeniably clear that fruits and vegetables lower your risk for a wide range of diseases. If there was a pill as powerful as fruits and vegetables, and with as few side effects, it would be hailed as a medical miracle. It would be front page news. And prescriptions might cost a fortune. There may be no better bargain in the world than fruits and vegetables.

Three of my neighbors have been stricken with cancer in the last couple of years. One died and another has less than a year to live, according to her prognosis. In all likelihood, neither of these neighbors will reach 60. It's gut-wrenching to see these formerly vibrant people become so worn down to the point that they can't even get out of bed some mornings. It's awful to witness them losing their color and energy and gradually withering away.

Would a change in their diet—especially if started in, say, their 20s—have prevented their cancers or improved their diagnoses? It's impossible to say. But in the aggregate, diet—and consumption of fruits and vegetables in particular—seems to have a substantial and sometimes dramatic effect on overall health. You do not want to get cancer. Improve your odds by eating a variety of fruits and vegetables. It may be a matter of life and death.

I hope that this series' introduction to these wonder-foods helps you serve them in ways that are pleasing and tasty for you. Fruits and vegetables should be a joy to eat, not medicine that you have to force yourself to take. Please avail yourself of the almost limitless cooking tips and recipes on the Net so that you can discover favorite ways to prepare and consume these amazing foods and make them a major part of your diet.

On a related note, coming up soon I'll feature an interview with my friend and accomplished chef Dino, who will let you know some simple rules of thumb for using common spices and bottled sauces to add flavor to your food (we'll focus mainly on vegetables for starters).

Here are just a few of the thousands of studies that show the health benefits of eating a sufficient quantity and variety of and fruits and vegetables. This is just a tiny sliver of the available data. Studies that reinforce the importance of fruits and vegetables in the diet are so frequent and plentiful, you can practically pluck them from the air. They're everywhere.

All of the following studies are recent and medium- or large-scale.

(Note: Let me know if you want the precise information—full journal name, volume, issue, authors, and so forth—on any of these studies to enable you to look them up. In the meantime, it's much quicker to just list the journal abbreviated name and issue year.)



The Netherlands Cohort Study tracked 62,573 women and 58,279 men, aged 55 to 69, for over six years. The more fruits and vegetables they ate, the lower their chance of lung cancer.
Cancer, 2000

Of 18,000 men, those who had detectable amounts of isothiocanates, a chemical found in cruciferous vegetables such as broccoli and bok choy, had a 36 percent lower chance of developing lung cancer than those without detectable amounts of the chemical. A number of compounds in cruciferous vegetables—some perhaps not yet discovered—work in tandem, and researchers warned the public not to rely on a pill form of the chemical.
Am J Clin Nutr, 2000

A study of 103 breast cancer patients in Australia found that those who ate the most fruits and vegetables had the best chance for survival.
J Clin Oncol, 2000

A study of more than 90,000 men and more than 240,000 women showed that for every 10 grams of fiber in the daily diet there is a 14 percent reduction in coronary events (e.g., heart attacks) and a 27 percent reduction in coronary deaths. Fiber is found in fruits, vegetables, whole grains, and legumes, but not animal products.
Archives of Internal Med, 2004

A study of 4000 men and women adults found that the those who ate the most dietary fiber had the lowest amount of concentrations of C-reactive protein (CRP) in their blood. A high CRP number is used as a predictor of future coronary events.
J Nutr, 2004

In a study of 1294 men with prostate cancer and 1451 men without the disease, men who ate the most fiber from vegetables in particular were 18 percent less likely to develop prostate cancer than those who ate the least.
Int J Cancer, 2004

A study of 900 men and women between the ages of 69 and 93 found, among other things, that men who ate the most fruits, vegetables, and cereral had the highest bone density. Bone health is a lot more than just calcium!
Am J Clin Nutr, 2002

To women who are breastfeeding or pregnant, or who may be pregnant in the near future: According to research at the Monell Chemical Senses Center in Philadelphia, when mom eats vegetables during pregnancy or if breastfeeding, baby is more likely to eat his or her vegetables. This is a profound finding, in my judgment: What you eat during this critical period could affect your child's eating habits, and thus overall health, for life.

Dad, your diet may have a major influence, too. If you say "Yum, these carrots taste great," I think that will have a far different effect than "Yuck, carrots again? Do we have to eat these?" The former will show your children that vegetables are tasty and appreciated; the latter response will teach your children to resent vegetables. Your children pick up and perpetuate your attitudes. Even better: Make the vegetables yourself and/or let the kids help. Even better still: Grow a little organic vegetable garden in the back yard and get the whole family involved. Experience shows that kids enjoy vegetables they grew themselves.



You may want to share some of these findings with your family members and loved ones. We may not be able to prevent cancer entirely, but we may be able to prevent over half of its occurrences—that's huge. Mainstream medical groups estimate that up to 70 percent of some cancers are preventable by lifestyle changes alone. And we'll see later on that that success rate may improve even more for diabetes and heart disease. Granted, you could do everything right and still get cancer or heart disease. Sometimes people are born with a genetic abnormality or heart defect, or other insurmountable conditions. But in most cases, our most common deadly diseases are not just something that happens to you when you get older. What you eat may determine whether you are stricken with them. Please take this to heart.

Next: A few more studies on the importance of making fruits and vegetables a major part of your diet, to drive home the point.

To Meat-Eaters: Easy Ways to Reduce Meat Consumption While Retaining Your Comfort Foods, Part 26 

Cooking Specific Vegetables
By now, you should be an old pro at these quick veggie side dish recipes. The basics of chopping, sauteing, steaming, and so forth, are really easy, and, fortunately, there's some margin of error. Not that you can be too lackadaisical. But for very little effort, you can fill up your plate with super-healthy foods, and with just a little bit of dressing them up and variety in their preparation, you can make vegetables a very welcome part of the meal—not a chore, but something you'll enjoy! To repeat from a past post: When we get rid of the saturated fat, accumulated toxins, and cruelty of meat, we want to replace it with nature's goodness; health- and spirit-building foods, not crap. Even though it's ok to totally junk out every now and then in small doses.

Next up: Let's see...I'm going to come back to potatoes later, because they make up a huge category that deserves a section of its own. Potatoes are really healthy, by the way, especially if you keep the skin on—a ton of vitamin C and potassium, among other things. But for now, let's turn to one of my all-time favorite vegetables—spinach.
