AND ABSORPTION TOPICS REVIEW PAPER
ANSWERS COMPLETE LEARNING PACK
◉ List and describe the functions of protein in the body. (2)
Answer: Supporting growth & maintenance, building enzymes,
hormones, and other compounds, building antibodies, maintaining
fluid & electrolyte balance, maintaining acid-base balance, prevent
blood clotting, provide energy & glucose
◉ Explain protein balance. (3)
Answer: - Balance protein intake w losses
- positive = using more than we excrete (growth, pregnancy,
recovery stage
- negative = more excreted than being consumed (fasting, disease,
fever, infections)
◉ Characterize foods in terms of protein amount and quality and
also identify proteins that are complementary. (4)
Answer: High-fish, poultry, cheese, eggs, milk, most soybean
products complementary-grains and legumes
, ◉ State the AMDR for protein. Calculate an individual's
recommended protein intake (RDA). (3)
Answer: .8 g protein per kg of body weight per day women: 46
g/daymen: 56 g/day
1 lb=.4536
◉ Describe characteristics and consequences of protein-calorie
malnutrition. (2)
Answer: deficiency: marasmus and kwashiorkor
excess: heart disease, kidney disease, adult bone loss
◉ Describe how genes and nutrition interact and the current reality
of using genetic testing to assess an individual's disease risk. (1)
Answer:
◉ Identify the strengths and limitations of vegetarian and meat-
containing diets. (3)
Answer: strengths of veg: defense from obesity, lower heart disease,
lower BP, lower cancer-they have to eat healthier things to get
needed nutrientsstrengths of omni: in pregnancy and infancy, in
childhood, no risk of B12 and other deficiencies, basically easier to
get needed nutrients
