The components of a basic diet do change through various stages of life. Infants, toddlers, teens, young adults, and mature adults all undergo biological changes which require different sets of nutrients, vitamins, minerals, and the three basic, carbohydrates, proteins, and fats. Scientists and health experts are continuously doing research to assess the bodily needs at these stages. An example would be the amount of calcium in one's diet. In infancy, milk it is a major factor in growth and development and continues until full maturity is reached. As we age, we lose the body's ability to utilize calcium and an increased intake of calcium and Vitamin D is needed after the age of fifty to prevent osteoporosis, a condition characterized by depleting bone density. More intake of dairy products (low in fat) are recommended. By researching each component listed above one can see the different stages the body needs.
