2. A food pyramid-shaped diagram representing a set of dietary guidelines for humans, typically based on a recommended number of servings from each of several food groups. Foods along the broadest row, at the bottom, are considered basic to human nutrition and have the highest recommended number of servings. Foods in the narrowest part, at the top, are considered to be nonessential and have the fewest number of recommended servings. In the middle row or rows are foods whose recommended servings fall between those two groups.
