Nutrition refers to the study of how food affects the body and how the body uses food for growth, maintenance, and repair. It involves the key nutrients that our body requires such as carbohydrates, proteins, fats, minerals, vitamins, and fiber, among others. A healthy and balanced diet ensures that our body receives all the nutrients it needs to function properly, as well as helps prevent chronic diseases such as obesity, heart disease, and diabetes. Nutritional education and awareness can help individuals make informed decisions about their food choices and lead a healthy lifestyle.
