Vegetarian? 6 Tips for a Healthy Vegetarian Diet

Kirstie Alley learned the hard way that cutting meat from your diet is not a

magic route to svelteness. As she told People magazine earlier this year, " For

seven months I was a vegetarian, and I can't tell you how much weight I gained

being a vegetarian! " (She actually does tell us: 83 pounds.) Indeed, while a

plant-based diet has been associated with many health benefits—including a

smaller risk of death from heart disease, lower LDL cholesterol levels, and a

reduced incidence of diabetes, obesity, and cancer—the diet has to be

" appropriately planned, " as the American Dietetic Association said in its recent

position statement on the subject.

What does that mean? Here are six tips to keep in mind if you're thinking of

going all—or partially—veggie.

 

Define what you mean by vegetarian. There are lots of variations on a vegetarian

diet. Most strict are vegans, who eschew any kind of animal products, including

butter and eggs. (Vegans disagree over whether to eat honey; some feel it's

cruel and exploitative of bees.) Less stringent are vegetarians who eat eggs or

dairy. Some, oxymoronically, eat fish, though the accurate term for them is

pescatarian. And then there are the newest additions, flexitarians, who

recognize the benefits of a plant-based diet and choose to reduce but not

eliminate their meat consumption. What route you go is a personal decision,

depending on your tastes, preferences, and views on the environment and the

proper role of animals. Think it over and figure out what fits into your life,

practically and philosophically. (Here's the skinny on red meat and health.)

 

Remember, the root of vegetarian is " veg, " not " junk. " Some vegetarians are

overweight, of course, and for reasons similar to those that cause obesity among

meat-eaters. (See this blog by a vegan doctor for details.) So beware of

swapping out meat for nutritionally empty, calorie-dense foods. After all, says

Walter Willett, chair of the department of nutrition at the Harvard School of

Public Health, a diet based on Coca-Cola, pizza, and french fries is technically

vegetarian. But " the healthiest vegetarian diet will have a lot of vegetables,

fruits, nuts, and legumes, " he says. At meals, half of one's plate should be

devoted to nonstarchy, colorful vegetables, he says. Whole grains also are

important, but confine those to a quarter of your plate. The other quarter

should contain lean, plant-based sources of protein, like tofu or beans.

 

Replace the meat. Contrary to popular belief, it's not particularly hard for

vegetarians to get enough protein, says Dawn Jackson Blatner, a Chicago-based

nutritionist and author of The Flexitarian Diet. As sources of protein, an ounce

of meat and a quarter cup of cooked beans are roughly equivalent. Soy and quinoa

are both good choices because they're complete proteins, meaning they contain

the essential amino acids in the right proportions. People used to think you

needed to eat incomplete proteins together in the same meal to make up a

complete protein, but that view has been debunked; simply eat a variety of

plant-based protein sources throughout the day, and you'll be fine. To replace

the savory taste of meat, try a portobello mushroom burger, cooked tomatoes,

seaweed products, and (in moderation) Parmesan cheese, says Blatner.

 

Watch your nutrients. Vegetarians, especially vegans, should be careful to get

enough omega-3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and

B-12, according to the ADA. It says a balanced vegetarian diet can meet current

recommendations for those nutrients. For calcium and vitamin D, consume enough

dairy or a milk substitute that's been fortified, Blatner says. The ADA also

recommends leafy greens like bok choy and kale and calcium-fortified fruit

juices as sources of calcium that's bioavailable (that is, in a form your body

can readily use). And many breakfast cereals are fortified with vitamins D and

B-12.

 

Zinc is found in soy products, legumes, grains, cheese, and nuts, the ADA says.

As for iron, the form found in plant foods is different than what's in meat

sources, and its absorption may be influenced by other components of the

diet—coffee and tea inhibit absorption, while vitamin C enhances it. Good

sources or iron: fortified cereal, oatmeal, lentils, beans, tofu, and spinach.

(Do not take iron supplements unless your doctor recommends them.) The jury is

still out on whether plant-derived omega-3s are equivalent to those from seafood

sources. One way to hedge is to take an algae extract supplement to get the two

forms of omega-3 that aren't found in plants.

Read labels. Vegetarian packaged and processed foods are subject to the same

hazards as the nonvegetarian alternatives. As pointed out in the Eat This, Not

That Supermarket Survival Guide, there are better and worse choices in the

frozen meatless entrée aisle. One package of Celentano Eggplant Parmigiana, for

example, contains 660 calories, 44 grams of fat (10 of which are saturated), and

960 milligrams of sodium. Compare that to Kashi Black Bean Mango, with 340

calories, 8 grams of fat (1 gram saturated), and 430 milligrams of sodium.

Blatner recently did an analysis of meatless hot dogs and burgers and found that

while they generally have less fat and more fiber than the meat alternative,

they also have more sodium and less protein. So look at labels showing nutrient

content and ingredients the same way you would with any other food. And don't

forget the calories—they still count, as Kirstie Alley found out.

 

Ease into it. If you've decided to become a vegetarian, don't go cold no-turkey.

" Try making half your meals during the week meatless, " says Tara Gidus, a

nutrition performance coach and ADA spokesperson. " Then try three quarters of

your meals the next week. " And remember that it's not all or nothing in terms of

your health. If vegetarianism is not for you, pick lean cuts of meat, and don't

make them the center of every meal. Instead, sprinkle them into a diet based on

vegetables and fruits, whole grains, and " good " fats like olive oil. Omnivores

can be perfectly healthy, too!
