Review for test #3 1. Calcium is not well absorbedless that 30% 2. A major mineral means you need more of it. 3. The six major minerals are calcium, phosphorus, magnesium, sodium, potassium, and chlorine. The rest are trace minerals, which are not less important, but you just need them in less amounts. 4. Minerals are 0 calories. 5. The best source of iron is beef, liver, or meat. 6. The best source of zinc is beef, liver, or meat. 7. Vitamin C will help you absorb iron twice as much (double the absorption). 8. Sea salt, they say, contains iodide, but it is silly to pay more and get nothing extra for it.Sea salt is not better than table saltiodine leaves as a gas (sublimes from solid to gas form). 9. We need iodide to make thyroid hormone, which is important because it influences our overall metabolism. Also, if you don’t have enough iron, you will be fatigued, and children that are deficient won’t grow. Finally, you need it to prevent goiter, an enlargement of the thyr oid (around the Great Lakes and west = the goiter belts). 10. The major function of zinc: for many enzymes systems to work, for sexual maturation and growth, for wound healing, for protein metabolism and immune system. 1. Fluoride deficiency will result in dental caries (holes in teeth). 12. There is 500 mg of calcium carbonate in Tums, but since calcium carbonate is only composed of 40% calcium, there is 200 mg of pure calcium in Tums. 13. Iron is VERY POORLY absorbed; only 5-10% of iron is absorbed by normal adults. 14. The best source of potassium is potatoes. 15. If you don’t have enough potassium, it may result in cardiac arrest or an irregular heartbeat (death) [also caused by too much]. 16.The major function of magnesium that it is needed as part of bones and part of muscle; also, it is an activator of more than 300 enzymes, and it’s necessary to maintain electrical potential of nerve and muscle and for transmission of never impulses. 17. The major function of c hromium is that it acts as a cofactor for insulin, which is needed for maintaining normal glucose metabolism (chromium in humans declines with age). 18. Phosphorus is present in all foods especially milk and milk products and liver and other animal-food protein sources. About half the phosphorus in the USA diet comes from milk, meat, poultry, and fish. 9. The main sodium food source is table salt. Only 10% of salt intake comes from natural content of foods, 15% is from salt added during cooking and at table, and 75% from salt added during processing and manufacturing. 20. To decrease high blood pressure, lose weight. Also, eating salt doesn’t help for high blood pressure. 21. Folate RDA is over twice non-pregnant RDA (for increased blood supply and for growth of baby) so folate supplements are often prescribed. Also, need zinc for growth, B-12 for red blood cells, calcium, phosphorus, and magnesium for bones.In addition, iron supplements during pregnancy and after delivery ar e recommended (baby should have enough to last 3-6 months**); fluoride is needed for teeth to begin in the 5th month of pregnancy. Nutrients to double during pregnancyfolate and probably iron. 22. You can NOT make up nutrients from a skipped breakfast. 23. Teenagers need to snack to get nutrients. 24. Adolescents aren’t well fed because they are too busy, eat out with their friends, skip breakfast, poor choice of snacks, avoid milk because they falsely think it is fattening, fear of becoming fat, use of fad diets especially by girls, and girls don’t get enough milk,. 5. Vegetables should be added first to an infant’s diet (after about 4-6 months). 26. Nutrition advice for anorexia patients included increasing caloric intake slowly (start at 800-1200 kcal), balanced diet, vitamin/mineral supplements, small frequent meals, use liquid supplements if necessary, and reduce caffeine. Also, don’t overload food, and persuade them they are thin enough. 27. Do not drink alcohol during pregnancy because even one binge may increase the risk of fetal alcohol syndrome (brain damage and physical retardation in infants). 28. The biggest advantage of breast milk during pregnancy is its immune factors. 9. Parents shouldn’t tell children to clean their plates. 30. How do you encourage children to try new foods? 31. In order to encourage a child to eat, be positive, when they are finished take their plate (they will snack later), don’t tell them there are people starving, don’t give rewards for eating. 32. Older folks who have baby aspirin every day bleed more in the gut (gastrointestinal bleeding), so they need more iron. 33. As you age, BMR decreases, you need less food and more exercise, your appetite decreases, and usually you don’t get enough nutrients. 34.The primary function of water is as a solvent; it transports nutrients to cells and removes waste. Also, it lubricates joints, food in the mouth, and helps lubricate food as it moves down the digestive tracts. Water is needed in the chemical reactions of digestion and must be available for digestion to occur. Water helps regulate body temperature by secreting sweat and is a structural component of the body (it is necessary to retain the shape of cells and tissues). 35. Complex carbs are: bread, cereal, pasta, and vegetables. 36. Thirst is not an adequate guide for infants, those who are sick, and athletes. 7. 50-75% of body weight is water. 38. Hyperactivity in children is caused by caffeine, not sugar. 39. There is NO nutrient herbal preparation that will cure cancer. 40. The best advice to prevent cancer is to eat a variety of foods, get all nutrients, and help prevent too much harmful junk getting into you. 41. RDA for calcium for adults 51 and older is 1200 mg. 42. There are 300 mg of calcium in a glass of milk (it doesn’t matter whether it is skim, whole, 1%, or 2%). 43. Common food allergies are nuts, soy, milk, and eggs. 44. When u nder stress, the hormone cortisol produces fat. 45.A critical period during pregnancy defines a time early in pregnancy when an event happens and will never happen again. It is a certain time during development in which the event occurs that will have irreversible effects on later developmental stages (it is usually a period of cell division). 46. Colostrum contains immune factors and anti-infection that will help a baby. 47. The WIC program is a nutritional education component that takes care of people who can’t take care of themselves. 48. The major function of phosphorusit has more functions that any other mineral. 49. Advantages of infant formula = father can feed. 0. Your peak bone mass is from 25-30 years old. 51. 5 reasons girls get osteoporosis: girls live longer, guys drink more milk, girls get pregnant and breastfeed, girls are smaller (have smaller bones). 1. Iron is NOT a major mineral. 2. Females need more iron—it is almost impossible for females to eat a diet providing the RDA for iron and stay within 2000 kcal. 3. Iron deficiency anemia may be the most prevalent deficiency disease in humans. 4. PICA = eating non-food items (laundry starch, clay, ice cubes), may denote low iron intake 5. OJ would help you absorb more iron from your diet (double the absorption). . Iodide toxicity also results in goiter. 7. Copper deficiency hardly ever happens. 8. Fluoride is not essential, but is essential for teeth. 9. Chromium deficiency results in impaired glucose tolerance. 10. Sodium has a small role in high blood pressure. 11. Monosodiumglutamate (MSG) adds sodium big time. 12. The major function of iron is that it is a constituent of hemoglobin in red blood cells and myoglobin in muscle. Also, iron is essential in transportation of oxygen from lungs to tissues and it’s needed for oxidation-reduction reactions. 13. Minerals are essential, but do not provide energy (no calories).Many are needed to make body structures such as bones, need ed as activators for enzyme systems, and they are poorly absorbed and can definitely be harmful if taken in excess. 14. 99% of calcium is in the bone with 1% in body fluids. 15. Dairy council said calcium may have an effect on weight loss. 16. Phyates acid in seeds, nuts, and grain decrease calcium absorption. 17. Females do not have enough calcium! 18. You MUST get enough calcium from childhood to age 25. 19. Calcium is enriched in some sources such as OJ and bread. 20. Most people don’t know what’s in the supplements they take. 1. 10 million Americans over 50 have osteoporosis, 1. 5 million have a bone fracture, 1 in 5 who have a hip fracture die. Women lose 6 inches from osteoporosis. 22. Phosphorus in excess in the diet probably does not negatively affect calcium absorption. The problem is that high carbonated beverages/soda take the place of milk intake. 23. The FDA cited over 18 manufacturers of Coral Calcium for making false claims that the supplement is a cure- allthe U. S. Marshalls seized $26 million worth. 24. Phosphorus is an essential component of bone mineral, where it occurs in the Ca:P of 2:1.About 85% of the phosphorus in the adult body is found in bone. Phosphorus is absorbed very well by the small intestine as free phosphate. 25. Availability of phosphorus in grains, especially bran, is doubtful because of phytates in grain which will bind with phosphorus. 26. 4 functions of calcium: bone formation, response to nerves, blood clotting, normal rhythm of heartbeat. 27. Functions of phosphorus (more functions than any other mineral): absorption of glucose, transport of fatty acids, buffering system. 28. Phosphorus is very well absorbed70% 29.Functions of magnesium: bones, muscle, enzyme activator, electrical impulse. 30. Americans age 15-24 have a HIGHER death rate than 20 years ago, not nutrition related but due to violent death and injury, alcohol and drug abuse, unwanted pregnancies, STDs. 31. By 18 months, the brain growth is 90 % complete and by 10 years, 95% complete, so there is no real adolescent spurt in head circumference. 32. The two major complications related to teenage pregnancy are low birth weight infants (LBW) and pre-eclampsia, which is toxemia of pregnancy characterized by hbp, albuminuria, edema of feet and legs. 33.Over 90% of adolescents snack. 34. There’s NO scientific evidence that foods such as chocolate, soft drinks, or peanut butter cause acne. 35. Peer pressure influences eating behavior. 36. Eating disorders increase among college-aged females and ballet dancers because they want to be in control. 37. Eating disorders should not be treated by amateurs—you need a team of health professionals: psychiatrist, dietitian, physician. 38. No particular nutrient of type of food can retard the aging process. 39. Buillion is clear soup—no nutritional value. 40. Stories of unusual longevity in other countries were found to be untrue. 1. Lactose intolerance = eat cheese, yog urt, or lactaid milk. 42. The elderly need to either increase calories or decrease calories, depending upon whether they are skinny or fat. 43. As you age, basal metabolic rate decreases each decade after maturity (you need less calories to stay alive, need to move more). 44. No RDA for 100 year olds, only for 70 and under. 45. Dehydration is the worst thing for you because you can die from it, especially athletes. 46. Infant birthweight is the single most important indicator of the infant’s future health status.A low birthweight (LBW) baby is defined as weighing less than 5. 5 lbs. 47. Risk factors for pregnancy include heavy smoking, alcohol abuse, age 15 or under, among others. 48. You need . 4 mg of folic acid/day (pregnancy). 49. Effects of nutrient deficiencies during pregnancy include: calories (low infant birthweight), vitamin D (LBW), folate (miscarriage and neural tube defect—brain and spinal cord defects) 50. During pregnancy, women should be under the care of a health professional. 51. One of the smallest increases recommended is for energy.Pregnancy requires only 300 extra kcal per day during the 2md and 3rd trimesters. 52. During pregnancy, women should select foods of high nutrient density. 53. Weight gain should be in second half of pregnancy. 54. 25-30 lbs. = total weight gain for pregnant women. 55. Practices to avoid during pregnancy: limit caffeine, stop smoking, do not take any prescribed medications, do not use street drugs, do not diet, do not drink alcohol. 56. Advantages of breast feeding: nutritionally superior to any alternative, contains a variety of anti-infectious factors and immune cells, mother’s uterus shrinks faster. 57.Colostrum: a yellow milk-like secretion from the breast, rich in protective factors that comes into the breast before milk is ready for secretion. It starts in first day or so—may be present for up to 2 weeks. 58. The infant doubles his/her birth weight in the first 3 to 4 months; tr iples before year one. 59. For the first four months, 1/3 of the calories are needed for growth. During 4-12 months, the baby needs 10% or less for growth and the rest for activity. 60. Start new foods one at a time so that allergies can be detected. Rice cereal is usually started first mixed with formula to make it very dilute. 1. Never feed honey to an infant since honey may contain botulina spores. 62. Don’t feed baby skim milkbabies need calories and the fat for growth. 63. Age infants should start having table food = 1 year. 64. Reducing the risk of cancer = eat cruciferous vegetables (broccoli, cabbage, kale, turnips, brussel sprouts). 65. Red wine MIGHT help cancer (not sure). 66. Exercise when you are feeling stressedprevent cortisol from building up body fat. 67. Men eat less during stress and women eat more. 68. Mild depression or chronic stress harms immunity. 69.There is a link between stress and the urge to eat. 70. Over 75-90% of all doctor’s office visit s are for stress-related ailments and complaints. 71. Water is the most important nutrient. 72. You can live 30 days without food, but only 3 days without water (except in the desertless). 73. The average adult’s body weight is from 50-60% water, most controlled by hormones. 74. There’s no RDA for water. Sources of water include most beverages except those containing alcohol and caffeine; fruits and vegetables are 75% to 96% or more water, bread is 36% water, beef is 72% water. 5. Much water is lost through the skin, which cools the skin by evaporation. 76. Weight loss of over 20% by water leads to death. 77. Water intoxication is rarely seen in healthy people. 78. High altitude = low oxygenneed more water. 79. There is low chlorine in bottled water. 80. Football players in summer practice may lose 6-8% of body weight by water. 81. Drinks with more than 10% sugar won’t get into the body as fast (Gatorade has about 10% sugar). 82. You lose water through breathing out, sweating, and through excretions.
