Food Pyramids
A New Healthy Eating Pyramid
In response to the federal government's Food Guide Pyramid (at
bottom), Harvard University
Nutrition professors have developed a new
healthy eating pyramid that reflects the latest research on the optimal diet. Some
highlights of the new version:
- Whole grain foods, vegetable oils, and fruits and vegetables are emphasized.
- Physical activity and weight control are emphasized.
- Red meat and refined grains (like white bread and white rice) are de-emphasized
and listed as items that should only be eaten sparingly.
- Nuts and legumes receive their own category.
- Dairy products are de-emphasized and placed in a category with calcium
supplements.
- A daily multivitamin tablet is recommended for most people, and moderate
daily alcohol intake is a halthy option unless this does not make sense for
the individual.
