Nutrition Handout

The nutrient and energy standards known as the RDA are currently being revised. The new recommendations are called Dietary Reference Intakes (DRI). The following chart provides the most updated goals for nutrient intake available for males and females between 31 – 50. For information about other ages, or special populations such as pregnancy or lactation, please go to www. nal. usda. gov.Nutrient FAT-SOLUBLE VITAMINS Vitamin A Retinol, beta-carotene and various other carotenoids RDA or DRI RDA Males: 1000 ug RE Females: 800 UG RE Functions in the Body/Benefits Helps maintain good vision (necessary for night vision), resistance to infections, and supports growth and repair of body tissues.

Helps maintain cell membranes, red blood cell integrity, protects vitamin A and fatty acids from oxidation. Helps make factors that promote blood clotting. Dietary Sources Milk, eggs, meat, fish liver oils. Beta-carotene and other carotenoids are found in: Green leafy vegetables – kale, spinach, broccoli, collard greens, parsley, turnip greens, escarole. Yellow vegetables carrots, sweet potatoes, winter squash, pumpkin. Yellow and orange fruits – mango, cantaloupe, papaya, and apricots.

An electrolyte that maintains normal fluid balance and proper acid-base balance, part of hydrochloric acid found in the stomach. Associated with insulin and required for the release of energy from glucose. Supports healthy bones, muscles, and blood vessels. Assists in iron absorption. Functions in the Body/Benefits Involved in the formation of bones and teeth. Essential component of thyroid hormones that regulate tissue growth and cell activity.Part of the protein hemoglobin which carries O2 in the body. Part of the protein myoglobin in muscle which makes O2 available for muscle contraction. Necessary for the utilization of energy as part of the cells’ metabolic machinery. Involved in bone mineralization, the building of protein, enzyme action, normal muscular contraction, and transmission of nerve impulses Involved in the formation of bone, as well as in enzymes involved in amino acid, cholesterol, and carbohydrate metabolism. Important in a variety of enzyme systems.A principal mineral of the bones and teeth; part of every cell; maintains acid-base balance.
