Occasional bingeing

Consuming 20 cans of diet soft drinks in a day

22

Early warning sign of anorexia nervosa is:

withdrawal from family

23

Major health risk from frequent vomiting due to bulimia nervosa is:

a potassium imbalance

24

Anorexia nervosa is a disease of

Teenage women

25

Critical goal in the early stages of treatment for anorexia nervosa is

allow person a feeling of control over her life

26

Bulimia nervosa patients often have a problem with:

an inability to control responses to impulse and desire

27

Complications of Bulimia in someone who purges

Ulcers, pitting of the teeth, and electrolyte imbalance

28

Pica = 

Repeated consumption of non-nutritive items, such as paper, clay, laundary starch, paint chips

29

False about eating disorders

30

Characteristic that differentiates anorexics from bulimics

Denies need for treatment

31

Functions of water

Transport medium

Lubrication

Temperature regulation

Constriction / dilation of capillaries

Perspiration

32

Water does not require any digestion

True

33

Osmosis

Movement of water from an area of low salt concentration to an area of high solute concentration through a membrane

34

What solutes influence osmosis

Electrolytes (sodium, potassium, and chloride)

Protein

35

How do we excrete water?

Kidney - urine

GI tract - feces

Skin - sweat

Insensible losses - drying of skin, moisture lost through breathing

36

How many liters are lost daily

2-3 liters

*Can change based on activity, temperature, and humidity*

37

Oral rehydration therapy

The act of providing water and electrolytes to reverse dehydration

38

Water-soluble vitamins

Vitamin C, B vitamins

Readily excreted in H2O

Not stored

Not toxic

Defficiencies quickly onset due to high excretion

39

Fat-soluble vitamins

A, D, E, K

Not readily excreted

Stored in the body (fat, liver, skin)

Highly toxic

Deficiencies develop slowly due to high storage levels

40

Vitamins are _______ while minerals are _________

organic, inorganic

41

Minerals only come from the environment

True

42

Vitamins can be created by plants and animals

TRUE

43

Block absorption of vitamins and minerals?

Phytic acid

44

Increasing abosrption of vitamins and minerals

MFP factor - meat, fish, and poultry

Vitamin C

Iron

45

Major Minerals

Bone - calcium, phosphorus, and magnesium

Electrolytes - sodium, potassium, and chloride

Protein - sulfur amino acids

 

46

Trace Minerals

Iron, copper, zinc, iodine, and selenium

47

Zinc

Cell replication and division - would healing

Defiency - poor growth and would healing, poor immune response

48

Iron

Component of myoglobin (hemoglobin)

Development of myelin sheath, neurotransmitters

49

Vitamin B12

Production of myelin sheaths

Activation of folate

Deficiency = from lack of intrinsic factor

- leads to severe neurological problems and pernicious anemia

50

Folate

Deficiency leads to neural tube defects (spina bifida), and improper DNA synthesis

51

Potassium

Positive intracellular ion that helps conduct muscle and nerve impulses

Defiency = leads to weakness, arrhythmia, excessive sweating, and eating disorders

52

Sodium

Positive extracellular ion

Exchange for potassium in nerve cells

53

Calcium

Large component of bone

Required for muscle contraction

54

Chromium

Aids in insulin binding to the cell to aid in the absorption of glucose and AA

55

Pyridoxine (B6)

Synthesis of non-essential AA, neurotransmitters

56

Vitamin C

Synthesis of collagen, and connective tissue

Deficiency leads to scurvy

57

Antioxidants

Protect against oxidative damage from free radicals

Vitamins = C, A, E

Mineral = selenium

58

Beta-carotene

is a vitamin A provitamin

59

Erythropoiesis

The formation of red blood cells

60

Hemoglobin

Transports oxygen to the body and delivers it to myoglobin, where it exchanges oxygen for carbon dioxide

61

Macrocytic or Megaloblastic anemia

Improper DNA synthesis from a folate deficiency leads to a decreased cell division and enlearged red blood cells called these

62

Deficiency in Iron

most common form of anemia

most common nutrient deficiency

most toxic mineral

63

Ferritin

Storage protein for Iron

64

Transferrin

The transport protein involved in delivering iron to the body

65

Iron needs are increased in this population

Premenopausla women because of increased iron lost during mensturation

66

Vitamin K (required)

required for blood clotting as it is a coenzyme in the formation of prothrombin

67

Anticoagulants

Aid in reducing this clotting mechanism by vitamin K inhibition

ex. warfarin
