Grains

Grains are small, hard, and edible fruits or seeds of cereal plants. They are a staple food in many cultures and are a significant source of carbohydrates, which provide the body with energy. Grains can be classified into two main categories: whole grains and refined grains.

Whole Grains

Whole grains contain all parts of the grain kernel, including the bran, germ, and endosperm. They are considered more nutritious than refined grains because they contain fiber, vitamins, and minerals.

Examples of whole grains include:

• Quinoa
• Brown rice
• Whole wheat
• Oats
• Barley

Refined Grains

Refined grains have had the bran and germ removed, leaving only the endosperm. This process removes some of the fiber and nutrients, making refined grains less nutritious than whole grains.

Examples of refined grains include:

• White rice
• White flour
• White bread
• Pasta made from white flour
