A

complex carbohydrates

32
Q

how does a lack of carbohydrates damage the body

A

the brain heavily relies on carbs for energy

32
Q

how can using fats as al alternate source of energy damage the body

A

when fats are broken down and used at extreme rates, excessive ketones are produced which can cause an acidic environment

33
Q

how can proteins being used as an alternate source of energy be harmful to the body

A

amino acid breakdown puts extra burden on the kidneys, and the proteins that replace CHO as energy can no longer be used for tissue repair and building

34
Q

clinical effects of fiber to treat high cholesterol

A

fiber binds to cholesterol in the small intestines to prevent absorption

34
Q

clinical effects of fiber to treat type 2 diabetes

A

high fiber foods have a low glycemic index with fewer bg spikes

35
Q

clinical effects of fiber to treat diverticular disease

A

fiber increases fecal mass and prevents constipation by promoting laxation

36
Q

clinical effects of fiber to treat IBS

A

fiber promotes growth of beneficial colonic microflora

37
Q

Which item will raise an individual’s blood glucose more rapidly, a glass of orange juice or a whole orange?

A

a glass of orange because it will absorb quicker than an orange because it has way less fiber to slow the process down. it has a higher glycemic index

38
Q

how many calories of energy from carbohydrates will someone obtain from eating a cookie with 20g of carbohydrates in it

A

80 because 4cal(20g CHO) = 80 calories

39
Q

one serving of an item with 37g of carbs counts as how many carb servings

A

2.5 because 1 carb serving = 15g of carbs and 37g divided by 2 is 2.5

40
Q

adipose tissue

A

cells and tissues that store excess fat

41
Q

low density lipoprotein

A

transports cholesterol from the liver to the tissues

41
Q

high density lipoprotein (HDL)

A

carries cholesterol from the tissues to the liver for excretion

42
Q

cholesterol

A

fat-related compound found in bile

43
Q

triglyceride

A

synthesized from excess dietary carbs and fat stored in adipose tissue

44
Q

why are linoleic acid and a-linolenic acids considered essential?

A

the body cannot synthesize them, they must be obtained from diet

45
Q

trouble one may occur from removing all fat from their diet

trouble regulating body temp
unable to absorb fat-soluble vitamins from ingested food
difficulty getting pregnant

45
Q

how many calories per gram for fats?

A

9cals/g

46
Q

what are the structural building blocks of proteins

A

amino acids

47
Q
