You can stop ordering the egg-white omelet. Whole eggs not only contain 14 percent less cholesterol than previously believed, but "recent data also suggest that the cholesterol in food doesn't have as big an impact on the cholesterol level in our body as we thought," explains Bonnie Taub-Dix, RD, the author of Read It Before You Eat It. Plus, eggs pack 64 percent more vitamin D — all of it in the yolk — than they did when tested in 2002, probably thanks to changes in hens' diets. That's an important finding because many of us don't get enough D, a substance that can help boost immunity and strengthen bones. What's more, the yolks contain nearly three grams of hunger-busting proteins. Nix the yellow and you're likely to feel less satisfied, which can cause you to eat more later on.
