WGU D440 Saunders Review With 100% Verified Solutions
1. Carbohydrates 1. Carbohydrates are the preferred source of energy.
2. Each gram of a carbohydrate produces 4 kcal/g. Carbohy-
drates promote normal fat metabolism; inadequate carbohy-
drate intake attects metabolism.
3. Carbohydrates serve as the main source of fuel, providing
glucose for the brain and for the skeletal muscles during ex-
ercise; carbohydrates also promote erythrocyte and leukocyte
production, and cell function.
4. Major food sources of carbohydrates include milk, grains,
fruits, and vegetables.
2. Fats 1. Fats provide a concentrated source and a stored form of
energy.
2. Fats protect internal organs and maintain body tempera-
ture.
3. Fats enhance absorption of the fat-soluble vitamins.
4. Fats provide 9 kcal/g.
5. Inadequate intake of essential fatty acids leads to clinical
manifestations of sensitivity to cold, skin lesions, increased
risk of infection, and amenorrhea in women.
6. Diets high in fat can lead to obesity and increase the risk
of cardiovascular disease and some cancers.
3. Proteins Proteins
1. Amino acids, which make up proteins, are critical to all as-
pects of growth and development of body tissues and provide
4 kcal/g.
2. Proteins build and repair body tissues, regulate fluid bal-
ance, maintain acid-base balance, produce antibodies, pro-
vide energy, and produce enzymes and hormones.
3. Essential amino acids are required in the diet because the
body cannot manufacture them.

4. Complete proteins contain all essential amino acids; in-
complete proteins lack some of the essential fatty acids.
5. Inadequate protein can cause protein energy malnutrition
and severe wasting of fat and muscle tissue.

2. Vitamins promote life and growth processes and maintain
and regulate body functions.
3. Fat-soluble vitamins A, D, E, and K can be stored in the body,
so an excess can cause toxicity.
4. The B vitamins and vitamin C are water-soluble vitamins,
are not stored in the body, and can be excreted in the urine.
