Probably, I know I distrust most of the food "science".
When I stuck to "food" pyramid, I was the most unhealthy, overweight, and unhappy I've ever been. When I basically switched to high fat, high protein, and lowish carbs,I got healthier and more importantly my hormone profile went back to normal and I wasn't depressed anymore.
It's astounding what lies the government pushes around food, and how damaging it can be to your life!
