A

a class of nutrients contaiing starches, simple sugars, glycogen, and dietary fiber

35
Q

what are simple sugars?

A

considered simple because they are small molecules and require little or no digestion before they are used by the body
ex:fruits, milk, vegetables

36
Q

what are monosaccharides?

A

(mono=1 and saccharide=sugar) consists of one sugar molecule

37
Q

what are some examples of monosaccharides?

A

glucose(blood sugar)(only form of sugar used for energy and fructose and galactose can be converted into glucose), fructose(fruit sugar), and galactose

38
Q

what are dissaccharides

A

(di=2 and saccharide=sugar) consists of two molecules of monosaccharides linked together

39
Q

what are complex carbohydrates

A 
a subclass of carbohydrates(polysaccharides) includes starches, dietary, fiber, and glycogen
ex:starches, breads, veggie, potatoes, rice ,beans, wheat, corn, and pasta
40
Q

what are dietary fibers?

A

a subclass of complex carbohydrates with a high ratio of plant material that is not absorbed by the body. It is not used as energy (helps with elimination), has no calories and prevents colon(large intestine)cancer

41
Q

what is insoluble fiber?

A

doesn’t dissolve in water, it “holds” water and it speeds up the elimination of waste products from the intestinal tract
ex: bran, raspberries, skins&seeds

42
Q

what is soluble fiber?

A

dissolves in water and produces a gel. It can decrease cholesterol and slows absorption of glucose(good for diabetes)
ex:beans, apples, cheerios, grapefruit, and nuts

43
Q

what are fats?

A 
a class of nutrients that supply more energy per gram than carbohydrates or protein
1 g=9 cal
44
Q

How does fats function in the body?

A

supplies energy, insulation(thing that keeps us warm), and structure (cell membrane)

45
Q

How does fat function in diet?

A

flavor(absorbs flavor from cooking), satiety(satisfying> fills you up more), and texture(creamy)

46
Q

what are cholesterols and how are they produced and function

A

they are produced by the liver and supplied by certain food. They’re broken into lipoprotein(takes fat around the body) its is needed for production of hormones and to digest food

47
Q

what are LDL(low density lipoproteins)

A

bad cholesterol

48
Q

what are HDL(high density lipoproteins)

A

good cholesterol

49
Q

what are saturated fats?

A

(usually solid at room temp, fats that contains single bonds between carbon atoms and the max number of hydrogen atoms bonded to carbon) unhealthiest fat

50
Q

what does saturated fats do?

A

raise cholesterol
reducing intakes=LDL decreases (good) and increasing intakes=LDL increases(bad)
HDL is unaffected

51
Q

what are unsaturated fats?

A

fats that contain one or more double bond between carbon atoms and have less than the max number of hydrogen atoms bonded to carbon. considered healthier than saturated fats

52
Q

what does polyunsaturated do?

A

(sunflower&corn oil) lowers LDL(good) and lowers HDL(bad)

53
Q

What does monounsaturated do?

A

(olive,canola, and peanut oil) lowers LDL(good) and doesnt change HDL(good) The only way to raise HDL is to exercise

54
Q

What are proteins?

A

a class of nutrients consisting of long chains of amino acids, which are the basic components of body tissues and provide energy 1g=4 cal

55
Q

what are essential amino acids?

A

nine amino acids that cannot be manufactured by the body and must be supplied by food

56
Q

what are nonessential amino acids?

A

eleven amino acids that can be manufactured by the body

57
Q

what are incomplete proteins?

A

lacks one or more of the amino acids (peanut,beans,whole grains, veggies)

58
Q

what are complete proteins?

A

contains all nine essential amino acids (soy, meat, poultry, fish, egg, milk)
all 9 essentials must be present in order to synthesize the nonessential

59
Q

What are the functions of proteins for the body

A

tissue repair, muscle structure, bone structure, excess protein is stored as fat, and body primarily made up of proteins, water and fat.

60
Q

what is water

A

comprises approximatelt 65% of a person’s body weight (depends on how much body fat a person has>more fat=less water.

61
Q

how many ounces of water are reccomended each day?

A

64 ounces

62
Q

what functions does water have in the body?

A

keeps body’s ph buffered(not too acidic and not too alkaline), transport gases, nutrients, and waste products throughout the body

63
Q

what is dehydration?

A

occurs when the amount of water excreted by the body exceeds the amount of water taken in
prolonged dehydration leads to kidney failure and death

64
Q

what are some causes of dehydration?

A

heavy physical activity, illness, diarrhea/vomitting, fever, adn alcohol

65
Q

what are vitamins?

A

organice substances that assist in the chemical reactions that occur in the body
excessive levels can be poisonious. They dissolve in fat tissue and are stored by body fat.

66
Q

what are the three fat soluble vitamins?

A

A, D, E, and K

Fat soluble vitamins can be stored in the body

67
Q

What are some water soluble vitamins?

A

B and C
excessive levels are excreted in urine
they must be ingested in food or supplements. Water soluble vitamins cannot be stored in the body

68
Q

What are the only vitamins that the body cannot manufacture?

A

D and K

69
Q

What are some vitamin deficiencies

A

(vitamin D)- Rickets: improper hardening of bones

(vitamin C)- Scurvy

70
Q

What are minerals

A

inorganice substances that contribute to the normal functioning of the body(homeostasis) and form structural components of the body
ex:Na- sodium(found in salt and an electrolyte-eletrically charged)

71
Q

What is table salt?

A

Na++Ci-=NaCi(sodium chloride)

a diet high in this leads to dehydrations(water loss and high blood pressure)

72
Q

what us calcium?

A

the most abundant mineral in the body

73
Q

what are some functions of calcium?

A

found in bones and teeths, prevents osteoporosis(disease wgere bones weaken and become brittle)

74
Q

what is the amount of mineral u need to consume each day?

A

about a tablespoon. Your body needs a greater amounts of mineral than vitamins

75
Q

What are some examples of dissaccharides?

A

sucrose (1 glucose+1 fructose=table sugar), lactose (1 glucose+1 galactose=milk sugar), and maltose (2glucose=malt sugar)

76
Q

What is the maximum heart rate

A

220 minus your age

77
Q

What is the resting pulse rate

A

60-80 beats per min
