it cant, it was found to be useless

the food pyrmid is a thing of the past

The food pyramid is not designed for health. Its based on FTC or trade guidelines or slightly modified in each country based on their trade agreements.

This information is well hidden from the general public and is also why they teach the food pyramid in public schools, so that it affects our culture as far as food choices to support these trade agreements.

So, diet is an economic issue.

As far as health. The food pyramid is really upside-down. According to Harvard.University, their studies have shown that we are all eating way too many white flower products and not enough fruits and vegetables.

They also do not define good and bad fats. They generalize and say to avoid all fats, thus adding to the confusion.

It didn't take long for the Harvard food pyramid to be taken down from main stream media. You can't find it anymore.

Great question, though.
