Grains

Grains are small, hard, dry seeds harvested for human or animal food. They are a staple food in many cultures and provide a major source of energy and nutrients.

Types of Grains:

1. Whole Grains: These grains contain the entire grain kernel - the bran, germ, and endosperm. Examples include brown rice, quinoa, and whole wheat.
2. Refined Grains: These grains have been processed to remove the bran and germ, resulting in a finer texture and longer shelf life. Examples include white rice and white flour.

Nutritional Value:

Grains are a good source of carbohydrates, which provide energy for the body. They also contain important nutrients such as fiber, B vitamins, and minerals like iron and magnesium.
