Nutrition Study Guide 1.) Essential amino acids for adults – (cannot be synthesized in the body) 9 essential amino acids histadine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. (MATT V PHILL) (arginine used to be considered essential – not now) 2.) Proteins are needed for the growth and repair of all tissues in the body. Functions of Proteins: For building new tissues in growing children, during pregnancy, in athletic training and after injury. For upkeep of tissues already built and replacement of regular losses such as skin, hair, and nails. Regulates internal water and acid-base balance. As a precursor for enzymes, antibodies, some hormones, and one of the B vitamins. For milk formation when mothers breastfeed. If the diet doesn’t provide enough carbs and fats to meet the energy needs, proteins are burned for energy. 3.) RDA is based on 0.8 g/kg of body weight per day. Take your weight in pounds and divide by 2.2 to get kg. 4.) 3 important substances synthesized by amino acids within the cell – 5.) Cereal grains – low in lysine – not a complete protein. 6.) Complementary proteins – 2 or more protein foods whose amino acid composition complement each other so that the essential amino acids missing from each are supplied by the other. Ex. Beans and rice 7.) Legume that contains the most complete protein: dried beans and peas 8.) Nitrogen equilibrium – the amount of nitrogen excreted equals the amount of nitrogen eaten in protein. The diet contains enough, or more, to meet body needs for protein. * All essential amino acids must be present in adequate amounts. Positive nitrogen balance – nitrogen intake in food is more than the amount of nitrogen being excreted. This happens during growth periods and recovery from a disease Negative nitrogen balance – more nitrogen is being excreted than is being taken in from food. During starvation, untreated diabetes, fever, restricted diets. 9.) Complete proteins are those foods that contain all the essential amino acids in the correct amounts and in the correct proportions to maintain life and support growth when used as the sole source of protein food. * All animal proteins are complete All of the essential amino acids must be present at about the same time with enough calories to make a complete protein. Have to have enough calories! 10.) Kwashiorkor is malnutrition caused by protein deficiency. Growth slows, hair loses color, and skin is scaly and had sores, body swells with edema, easily gets diseases. Happens between birth and age 2. - PKU is an inborn error of metabolism. Defect must be found close to birth – can start low phenylalanine diet 1 or under – child will usually be ok. The child needs to know what to eat, can never grow out of it.
