Reshaping the Food Pyramid
It's not just how much you eat that counts. Consuming fewer carbs and more "healthy" fats may help stave off chronic disease.

The Food Guide Pyramid, the U.S. Department of Agriculture's map of what's supposed to make up a healthy diet, is familiar to everyone from schoolchildren to health-conscious senior citizens.
But recent research involving more than 100,000 people could turn the pyramid on its side.
The study found that people whose diets contained fewer carbohydrates--foods like bread and cereals--and a bigger proportion of "healthy" fats, such as olive oil, than recommended by the pyramid were 20% to 40% less likely to develop chronic disease than those whose diets more closely matched the USDA guidelines.
"The Food Pyramid is flawed," says study author Walter Willet, MD, a professor of nutrition at the Harvard University School of Public Health. "It says all fats are bad, all complex carbohydrates are good, all protein sources offer the same nutrition, and dairy should be eaten in high amounts."
More specifically, the Pyramid recommends eating the following every day:
- Allergic Skin Disorders
- Bacterial Skin Diseases
- Bites and Infestations
- Diseases of Pigment
- Fungal Skin Diseases
- Medical Anatomy and Illustrations
- Noncancerous, Precancerous & Cancerous Tumors
- Oral Health Conditions
- Papules, Scales, Plaques and Eruptions
- Scalp, Hair and Nails
- Sexually Transmitted Diseases (STDs)
- Vascular, Lymphatic and Systemic Conditions
- Viral Skin Diseases
- Additional Skin Conditions
