What are the classes of mixed diet?

A mixed diet typically includes three main classes of food: carbohydrates, proteins, and fats. Carbohydrates, found in grains, fruits, and vegetables, provide energy. Proteins, sourced from meat, dairy, legumes, and nuts, are essential for growth and repair of tissues. Fats, present in oils, butter, and fatty fish, are crucial for hormone production and nutrient absorption. Additionally, a mixed diet includes vitamins and minerals from various food sources to support overall health.
