IMHO, grain (with the exception of the Exodus)...was not the main food in the biblical diet. My belief is that fish dominated the biblical diet. In one passage god tells the people to eat bread in the morning and fish in the evening.

He is telling them to load up on carbs before they start working. But, he's also telling them to avoid carbs at night (when they are more likely to store them). The amount of bread they probably ate in the morning was probably burned off by Dinner time.

It is my opinion that grain was a one meal a day thing...not the 6-11 servings the USDA is trying to pass off on us. In addition, the fruits and vegetables found in that region (olives, etc...) of the world are very healthy and contain good fats. It is clear, at least in my mind that while the biblical diet was higher than Atkins in carbs, that is was still relatively high in fat and protein and low in carbs compared to the diet the USDA is pushing on us.
