The Dark Side of Vegetarianism

By Steven Reinberg

WEDNESDAY, April 1 (HealthDay News) -- Despite its proven health benefits, a vegetarian diet might in fact be masking an underlying eating disorder, new research suggests.

The study, in the April issue of the Journal of the American Dietetic Association, found that twice as many teens and nearly double the number of young adults who had been vegetarians reported having used unhealthy means to control their weight, compared with those who had never been vegetarians. Those means included using diet pills, laxatives and diuretics and inducing vomiting to control weight.

There's a dark side to vegetarianism, said Dr. David L. Katz, director of the Prevention Research Center at Yale University School of Medicine. He had no role in the research.

"Adolescent vegetarians [in the study] were more prone to disordered eating and outright eating disorders," Katz said. "This is not due to vegetarianism but the other way around: Adolescents struggling to control their diets and weight might opt for vegetarianism among other, less-healthful efforts."

Vegetarianism, or a mostly plant-based diet, can be recommended to all adolescents, Katz said. "But when adolescents opt for vegetarianism on their own, it is important to find out why because it may signal a cry for help, rather than the pursuit of health," he said.

Katz said he thinks a balanced vegetarian diet is among the most healthful of dietary patterns, and the study suggests some of the benefits.

"Adolescents practicing vegetarianism were less likely to be overweight than their omnivorous counterparts and, were the measures available, would likely have had better blood pressure and cholesterol, too," he said. "Eating mostly plants -- and even only plants -- is good for us, and certainly far better for health than the typical American diet."

The study's lead researcher, Ramona Robinson-O'Brien, an assistant professor in the Nutrition Department at the College of Saint Benedict and Saint John's University in St. Joseph, Minn., agreed.

"The majority of adolescents and young adults today would benefit from improvements in dietary intake," she said. The study found, for instance, that the vegetarians among the participants generally were less likely to be overweight or obese.

"However, current vegetarians may be at increased risk for binge eating, while former vegetarians may be at increased risk for extreme unhealthful weight-control behaviors," she said. "Clinicians and nutrition professionals providing guidance to young vegetarians might consider the potential benefits associated with a healthful vegetarian diet, [but should] recognize the possibility of increased risk of disordered eating behaviors."

The researchers collected data on 2,516 teens and young adults who participated in a study called Project EAT-II: Eating Among Teens. They classified participants as current, former or never vegetarians and divided them into two age groups: teens (15 to 18) and young adults (19-23).

Each participant was questioned about binge eating, whether they felt a loss of control of their eating habits and whether they used any extreme weight-control behaviors.

About 21 percent of teens who had been vegetarians said they used unhealthy weight-control behaviors, compared with 10 percent of teens who had never been vegetarians. Among young adults, more former vegetarians (27 percent) had used such measures than current vegetarians (16 percent) or those who'd never been vegetarians (15 percent), the study found.

In addition, among teenagers, binge eating and loss of control over eating habits was reported by 21 percent of current and 16 percent of former vegetarians but only 4 percent of those who'd never followed a vegetarian diet. For young adults, more vegetarians (18 percent) said they engaged in binge eating with loss of control than did former vegetarians (9 percent) and those who were never vegetarians (5 percent), the study found.

Young adult vegetarians were less likely to be overweight or obese than were those who'd never been vegetarians. Among teens, the study found no statistically significant differences in weight.

"When guiding adolescent and young adult vegetarians in proper nutrition and meal planning, it is important to recognize the potential health benefits and risks associated with a vegetarian diet," Robinson-O'Brien said. "Furthermore, it may be beneficial to investigate an individual's motives for choosing a vegetarian diet and ask about their current and former vegetarian status when assessing risk for disordered eating behaviors."

Best Food for a Flat Belly

What if someone told you that the way you eat could whittle your waistline? Sure, you'd think. Give up carbs and rely on rabbit food. Not true! I'm happy to tell you that there are other, yummier ways to go. Certain foods and styles of eating can indeed help flatten your belly (and everywhere else, for that matter). Try these tips and you'll uncover an amazing middle in no time.

Gimme a C: I love pink grapefruit and that's a good thing, since research has found that foods that are naturally rich in vitamin C—think citrus fruit, cantaloupe and red peppers—can help reduce fat absorption. In fact, skip it and you may see your middle expand, since diets low in vitamin C have been linked to bigger waistlines. Meet your daily goal of 75 milligrams by snacking on an orange or a cup of strawberries. See how these small changes can add up to big results.

Tea up: Women with the highest consumption of catechins, the plant-based antioxidants in tea that may boost fat burn, put on fewer pounds over 14 years than those who drank less tea, The American Journal of Clinical Nutrition reveals. Try to choose green or white varieties, which contain the most catechins. Learn how to maximize the benefits of tea and other superfoods.

Peel it off: Reach for a banana and you'll banish bloat faster than you can say Buddha belly. The fruit contains 422 mg of potassium, which controls the amount of puff-producing sodium in your system. Toss a banana in your bag for a fabulous ab-flattening snack. Try our Flat Abs Fast plan for more bloat-reducing tips and tricks.

Go low: Consuming just one meal of low-glycemic-index foods, those that your body digests slowly, can help you feel fuller all day so you're less likely to pack your tummy with treats, a study in the Journal of the American College of Nutrition reports. Low-GI foods include oatmeal and vegetables (sorry, not potatoes), as well as some fruit like grapefruit and blueberries. Oatmeal Meatballs are a tasty way to curb cravings.

Stroll away your sweet craving: Loco for cocoa? Me, too. A little dark chocolate is fine, but if you've already hit your limit, try lacing up your sneakers! Chocolate lovers who walked for 15 minutes reported reduced hankerings during the walk and even afterward, according to a study in the journal Appetite.

Ditch high-fructose corn syrup: Scan labels and you're likely to see high-fructose corn syrup on many ingredient lists...even on things like tomato sauce! When you do, put down that jar and look for something else. Why? High-fructose corn syrup can cause a surge in your blood sugar, and some research suggests it messes up your hunger and satiety signals, like leptin, leaving you less satisfied and causing you to eat more. When leptin responses fail, it's tougher to control appetite. The result: Extra calories get deposited as fat. To prevent this, trade packaged foods with high-fructose corn syrup for ones with healthy fats and fiber—think veggies, hummus, nuts or sunflower seeds.

Snap your snack: Taking a photo of your plateful of food can keep you slim. People who took pictures of everything they ate for five days reported consuming fewer snacks and being less likely to go back for seconds than during a week-long period in which they kept a written food diary, a study from the University of Wisconsin at Madison finds. Try capturing your meals for a week to help eyeball portion sizes as well as color variety—aim for more green, less white (unless it's cauliflower).
