Food categories help us understand the different types of foods we eat and their nutritional benefits. The main categories include fruits, vegetables, grains, proteins, and dairy. Each category provides essential nutrients that our bodies need to function properly. For example, fruits and vegetables are rich in vitamins and minerals, while grains offer energy through carbohydrates. Understanding food categories can also help us make healthier choices. By including a variety of foods from each category in our meals, we can ensure a balanced diet. For instance, pairing lean proteins like chicken with whole grains and a side of colorful vegetables creates a nutritious and satisfying plate.
