Diet Myths Debunked

Eating wheat-free, skipping meat, and avoiding dairy are not necessarily good for you. Our experts investigate five "healthy" diets and tell us what you should really be eating and not eating.

The Gluten-Free Diet

Confession: I always thought I had the perfect diet -- after all, I'm a nutritionist. My meals were low in fat and salt, and loaded with fruits, vegetables, and whole grains. I was doing everything right. Except...I wasn't. Two years ago, after dozens of unexplained dizzy spells, my doctor informed me that my low-sodium meals plus a heavy workout schedule were driving my already low blood pressure down even further. Shocked, I followed my MD's orders and made friends with the salt shaker. Within a day or two, the dizzy spells disappeared, which just goes to show that even experts can make mistakes when it comes to good nutrition. "Any diet can be big trouble if it's taken to the extreme," says Andrea N. Giancoli, RD, a Los Angeles-based spokesperson for the American Dietetic Association.

Is your so-called smart diet actually a problem? Before you take another bite, see what a huge difference the right plan can make.

The Gluten-Free Diet

The Myth: It's no-carb, so you'll lose weight!

The Truth: Gluten-free is not a no-carb plan, and it shouldn't be used as a weight-loss strategy, says Tricia Thompson, RD, author of The Gluten-Free Nutrition Guide. The diet is designed for people with celiac disease, an autoimmune digestive disorder that causes intolerance to gluten, a protein found in wheat, rye, and barley products. There are major health dangers in going gluten-free: By skipping fortified breads and cereals, you're missing out on folate, which can lead to an increase in the amino acid homocysteine, raising your risk of a heart attack by as much as 200 percent. Pregnant women who don't get enough folate double their risk of preterm delivery -- and their babies have a 50 to 70 percent greater likelihood of developing certain birth defects. Replacing wheat products with gluten-free versions doesn't help much: A study in the Journal of the American Dietetic Association found that only 5 percent of the 58 gluten-free breads, cereals, and pastas studied were fortified with folic acid, the synthetic form of folate.

The Fix: Aim to get 400 micrograms (600, if you're pregnant) of folate a day. Choose healthy carbs, such as whole-grain breads and cereals that are fortified with B vitamins and that have plenty of fiber to keep you feeling full. If, like 1 in 133 Americans, you suffer from celiac disease, eat folate-rich leafy greens and gluten-free fortified foods and juices, and take a daily multivitamin. Also, try naturally gluten-free whole grains such as buckwheat, quinoa, and amaranth.

I just finished "Wheat Belly" by R. Davis. I find his argument for wheat-free much more cogent that yours.

You don't need an expert to look at the nutrition labels of dairy milk and almond milk. Which has cholesterol, saturated fat and LESS calcium? Yes dairy milk.

What a lame article! I hate it when so called "experts" try to scare people into believing they need to eat meat & dairy to be healthy. One paragraph talks about lack of iron in a meat/dairy free diet and then goes on to a long list of fruits, vegetables, and whole grains to "fix" the problem. I have to wonder about the author's connection to the meat/dairy industry.

Right - eat healthy. Period. You don't need gluten to survive. And I have experienced a huge reduction in inflammation since I removed it from my diet.

Eliminating dairy from your diet does not mean that you won't consume enough calcium. Silk (soymilk), for example, has more calcium per serving than cow's milk. On top of that, Silk, or other non-dairy milk, has no antibiotics. I don't see how not consuming dairy can be bad for you.
