1. Carbohydrates are our body's primary source of energy. They are found in foods such as bread, cereal, pasta, fruits, and vegetables.
2. Protein is essential for building and repairing tissues. It is found in foods such as meat, poultry, fish, beans, and eggs.
3. Fat is needed for storing energy, insulating our bodies, and protecting our organs. It is found in foods such as nuts, seeds, avocados, and oily fish.
4. Vitamins are essential for many bodily functions, including vision, immunity, and blood clotting. They are found in a variety of foods, including fruits, vegetables, and dairy products.
5. Minerals are essential for building strong bones and teeth, regulating fluids, and carrying oxygen in the blood. They are found in a variety of foods, including fruits, vegetables, and whole grains.
