Document Summary
Functional foods - foods that provide health benefits beyond their nutrient contributions. Energy capacity to do work; form found in food is chemical & can be converted to mechanical, electrical, or heat. Essential nutrients must obtain from food because body cannot make enough to meet physiological needs (40 known ones) Energy-yielding nutrients break down to yield energy the body can use (carbohydrates, lipids/fats, proteins) Nutrients chemical substances from food; provide e, structural materials, and regulating agents to support growth, maintenance and repair of the body"s tissues. Macronutrients (carbs, fats, protein) body requires them in relative large amounts - many grams daily. Micronutrients (vitamins, minerals) required only in small amounts - milligrams or micrograms daily. Organic nutrients carbohydrates, lipids, proteins, vitamins (contain carbon) Vitamins organic, essential nutrients but do not provide energy. Minerals inorganic, indestructible, not energy-yielding, found in structures as bones and teeth or in fluids of the body (ex. calcium, iron, zinc, copper)
