Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.Animal Feed: Foodstuff used especially for domestic and laboratory animals, or livestock.Potassium, Dietary: Potassium or potassium compounds used in foods or as foods.Sweetening Agents: Substances that sweeten food, beverages, medications, etc., such as sugar, saccharine or other low-calorie synthetic products. (From Random House Unabridged Dictionary, 2d ed)Vegetables: A food group comprised of EDIBLE PLANTS or their parts.Centrifugation, Density Gradient: Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)Eating: The consumption of edible substances.Food Preferences: The selection of one food over another.Diet Records: Records of nutrient intake over a specific period of time, usually kept by the patient.Fructose: A monosaccharide in sweet fruits and honey that is soluble in water, alcohol, or ether. It is used as a preservative and an intravenous infusion in parenteral feeding.Fruit: The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.Diet Surveys: Systematic collections of factual data pertaining to the diet of a human population within a given geographic area.Recommended Dietary Allowances: The amounts of various substances in the diet recommended by governmental guidelines as needed to sustain healthy life.Liver: A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.Animal Nutritional Physiological Phenomena: Nutritional physiology of animals.Taste: The ability to detect chemicals through gustatory receptors in the mouth, including those on the TONGUE; the PALATE; the PHARYNX; and the EPIGLOTTIS.Fatty Acids: Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed)beta-Fructofuranosidase: A glycoside hydrolase found primarily in PLANTS and YEASTS. It has specificity for beta-D-fructofuranosides such as SUCROSE.Glucosyltransferases: Enzymes that catalyze the transfer of glucose from a nucleoside diphosphate glucose to an acceptor molecule which is frequently another carbohydrate. EC 2.4.1.-.Nutrition Policy: Guidelines and objectives pertaining to food supply and nutrition including recommendations for healthy diet.Random Allocation: A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.Nutrition Assessment: Evaluation and measurement of nutritional variables in order to assess the level of nutrition or the NUTRITIONAL STATUS of the individual. NUTRITION SURVEYS may be used in making the assessment.Cholesterol: The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.Fish Oils: Oils high in unsaturated fats extracted from the bodies of fish or fish parts, especially the LIVER.
