Nutrition: the study of how food is used by the body
Six major nutrient groups:
Proteins: provide calories, synthesize new body tissue during growth, and replace worn-out cells
Carbohydrates: include sugars, starches, and fiber.
Fats: concentrated energy source, which provide more than twice as many calories as an equal amount of protein or carbohydrate. Can be saturated or unsaturated.
Vitamins: chemical compounds that are involved in various metabolic reactions in the body. Can be fat-soluble vitamins or water-soluble vitamins
Minerals: crystalline chemical elements that comprise about 4 percent of a person’s weight.
Water: perhaps the most vital nutrient.

(McVety, Ware and Ware) John Wiley & Sons, Inc. © 2009Food Preparation GuidelinesFundamentals of Menu Planning 3rd edition. (McVety, Ware and Ware) John Wiley & Sons, Inc. © 2009Avoid overcooking food.Steam, stir-fry, or microwave foods instead of boiling. If cooking in water cannot be avoided, use as little as possible and reuse that water in a soup or stock gravy.Keep food wrapped to prevent oxidation.If appropriate, keep foods cool to decrease the activity of enzymes.Do not add baking soda to green vegetables to give them a bright green color.Store foods in the dark or in opaque containers.Cut foods into medium-size pieces for cooking. Large pieces usually cook too slowly, and very small pieces promote oxidation and loss of vitamins into the cooking water.Avoid holding food at serving temperature for a prolonged period, as on a steam table. This procedure not only increases vitamin loss, but also affects texture and increases the risk of food poisoning.
