Assertion (A): Fruits and vegetables are placed at the bottom of a food pyramid.
Reason (R): They must be consumed in more quantities for good health.
Both A and R are true and R is the correct explanation of A.
The Food Guide Pyramid shows the types and serving sizes for the foods we should eat every day to stay healthy. Foods are placed in the pyramid in a way that shows how important they are to our health. We should eat more of the foods at the base than foods at the top.
For example, grains, fruits, and vegetable groups are at the base of the pyramid. Meat, dairy, and fat groups are toward the top. Though all groups are important, the plant foods are at the base so that we remember to eat more of those and less of the animal products and added fats.
