Good nutrition plays a positive role in good health, self-sufficiency, and quality of life.
An individual’s dietary intake will be affected as they undergo changes in their lives and move
from one stage of life to the next. Adequate nutrition is necessary to maintain cognitive and
physical functioning, to prevent, reduce, and manage chronic disease and disease-related
disabilities, and to sustain health and a good quality of life (Menu and Nutrition Requriements).
To meet the body’s daily nutritional needs while minimizing risk for chronic disease, an AMDR,
Acceptable Macronutrient Distribution Range, was established for carbohydrate to be 45-65% of
total calories, for fat, 20-35% of total calories, and for protein, 10-35% of total calories. It is also
suggested that no more than 25% of total calories come from added sugars (Menu and Nutrition
Requriements). The RDA is the average daily dietary intake level that is sufficient to meet the
nutrient requirement for nearly all healthy individuals of a specified age range and gender. The
following presentation will outline the nutrition needs for both a man and a woman throughout
the various stages of life.
Food provides the energy and nutrients that a body needs to be
healthy. Breast milk and formula provide adequate nutrition for an infant. They both contain all
the necessary vitamins and minerals for a baby. Children under the age of 2 need up to 50
percent of their calories to come from fat. Whole milk is a good source for fat after age one
(Infant and Toddler Nutrition). But, after age two or three, you can switch to low-fat milk. As an
infant grows, the daily recommended intakes of protein, fat, and water increase at small
incremental rates. This occurs because their weight increases at a gradual pace; therefore, their
nutritional values for each day also increase. After age one, it is important to watch out for iron
deficiency. Iron deficiency can affect a child’s physical, mental, and behavioral development,
and also can lead to anemia (Feeding Your 1- o 2-Year-Old, 2008). 500 mg of calcium is
recommended for toddlers between the age of one and three. After the age of three, dietary fiber
