Nutrition refers to the process of obtaining the necessary food and nutrients for health and growth. A balanced diet includes a variety of foods, such as fruits, vegetables, whole grains, proteins, and healthy fats. Proper nutrition supports bodily functions, boosts the immune system, and helps maintain a healthy weight. Physical activity involves any movement that engages the muscles and requires energy. Regular exercise, such as walking, running, or playing sports, improves cardiovascular health, strengthens muscles, and enhances flexibility. Combining nutrition with physical activity is essential for overall well-being and can reduce the risk of chronic diseases.
