Why are bread/grains still on the food pyramid?

Carbohydrates: First there is no longer a food pyramid. The recommended daily calorie component chart is shaped like a diamond. Carbohydrates are essential in a healthy diet. But, they should be a small part of the diet not the main component. Science now teaches us that only about 25% of your calories should come from carbohydrates.

Good question :-): Many people can tolerate grains and wheat breads, without difficulty. Some can be good sources of protein and other nutrients. If you're a person who doesn't tolerate these though, your own food pyramid would look different. Neurologist dr. David perlmutter has written a very interesting book about grains and the brain. http://tinyurl.com/mof6qj8 it provides some things to think about!
