The human diet consists of the foods and beverages consumed by individuals to provide essential nutrients for growth, energy, and overall health. It typically includes a variety of food groups such as fruits, vegetables, grains, proteins, and dairy. Each group offers different vitamins and minerals that are crucial for bodily functions. Dietary choices can vary widely based on cultural, geographical, and personal preferences. For example, some people may follow specific diets like vegetarianism or veganism, which exclude certain animal products. Understanding the balance of these food groups is important for maintaining a healthy lifestyle.
