A food pyramid is a visual representation of a balanced diet, showing which food groups to eat more or less of. It typically categorizes foods into groups and suggests the optimal number of servings from each group to maintain health. The most well-known version is the one developed by the US Department of Agriculture, which has been revised and adapted by various countries.
Key Features of a Food Pyramid:

Base:
Represents the food groups that should form the foundation of a healthy diet, consumed in larger quantities.

Apex:
Represents the food groups to be consumed in smaller amounts, typically fats, oils, and sweets.
Middle Layers:
Represent the other food groups like grains, fruits, vegetables, and protein sources, with varying recommendations for daily intake
