QuestionAnswer
Antioxidant vitamins Vitamins E,C,and A (in previtamin form of beta-carotene)have a possible link to reduced risks of certain cancers and heart disease.
Antioxidants function by delaying or preventing the destruction or breakdown of cell membranes in the presence of oxygen.
Fat-soluble vitamins Vitamins A,D,E,and K. Usually carried in the fatty portions of food. Can be stored in the body. Fairly stable in cooking
Water-soluble vitamins Vitamins B and C. Are not readily stored in the body.Excesses are generally excreted in the urine. Easily destroyed by air & cooking.
Water Is the principle body constituent; most indespensable of all nutrients.
What percentage of water makes up adult and infant body weight? 60% in adults and 80% in infants body weight
Minerals Inorganic elements and are essential for growth and normal functioning.
What are the groups of Minerals? 2 groups: Major(macro)minerals and Trace(micro)minerals.
Characteristics of Minerals Found in all body tissues and fluids, DO NOT furnish energy but regulate body process that furnish energy, occur naturally in foods, and are stable in food preparation.
What Minerals are needed in large amounts? Major(macro)minerals
Name the Major(macro) minerals. Calcium,Phosphorus,Potassium,Sodium,Magnesium, Sulfur, and Chloride
What Minerals are needed in small amounts? Micro(trace)minerals
Name the Micro(trace) minerals Iodine,Zinc,Iron,Selenium,Copper,Manganese,Chromium,Fluoride,and Molybdenum
The amount needed from Major(macro) minerals 100mg+/daily

Sodium deficiency Cramps, mental confusion,apathy,appetite loss.
Sulfur function Essential contituent of proteins, metabolism
Sulfur deficiency None exhibited except in protein defiecieny
Phosphorus function Essential component of bone, energy metabolism, acid base balance.
Phosphorus deficiency Rare, but may occur in pt's using aluminum hydroxide antacids.
Magnesium function Bone mineralization, muscle contraction & relaxation, blood pressure regulation
Magnesium deficiency Nausea, muscle weakness, confusion,tetany(rare)
Manganese function General metabolism, formation of bone
Manganese deficiency Reduced bone mineralization, dermatiits, and altered lipid & carbohydrate metabolism.
Selenium function Antioxidant
Selenium deficiency Cardiomathapy
Chromium function Maintenance of normal glucose
Chroimium deficiency Impaired glucose tolerance, diabetes like symptoms
Fluoride function Increases tooth resistance to decay
Fluoride deficiency Increased suspectibility to tooth decay
Copper function Necessary for utilaztion of iron
Copper deficiency Anemia, vascular skeletal problems
Zinc function Part of many enzymes involved in metabolism
Zinc deficiency Loss of appetite, skin changes, growth retardation
Iodine function Part of thyroixn-which helps regulate metabolism, growth & development
Iodine deficiency Goiter-enlarged thyroid glandCretinism-mental and physical retardation of fetus
Iron function Necessary for transport of oxygen use in body, part of some enzymes
Iron deficiency Microcytic, hypochromic anemia, fatigue, weak
Vitamins Organic compounds needed in small amounts for growth and maintenance of life.
Precursor (pro-vitamin) a substance that precedes and can be changed into an active vitamin; for example carotene is the precursor of Vitamin A.
Hypervitaminosis is the excess of two or more vitamins
Synthetic man-made vitamins
Enriched or Fortified the addition of nutrients to a food often in amounts larger than the amount found naturally in that food
Restored foods in which nutrients lost in processing are replaced
Vitamins with General metabolism functions Biotin, Panthothenic acid, Niacin,and Riboflavin(B2)
Riboflavin (B2) deficiency Sore throat,ariboflavinosis,glossitis, cheilosis(disorder of the lips & mouth characterized by scales & fissures
Niacin deficiency Pellagra
Pantoethenic acid deficiency Listlessness,fatigue(rare)
Biotin deficiency Alopecia, conjuctivitis, dermatitis

What group of people are at risk for low intake of Vitamin B12? Strict vegetarians, 50 and over, and individuals who had stomach surgery.
Toxicity a condition that results from exposure to excess amounts of a substance that does not cause adverse amounts, usually occcurs from use of large supplemental doses of vitamins or minerals and not from food sources.
