anorexia nervosa

an eating disorder characterized by starving behavior,being underweight, and amenorrhea

binge

to eat an excessively large amount of food within discrete period of time, usually considered to be about two hours

Binge Eating Disorder

an eating disorder characterized by binging, without any purging or restriction

bulimia nervosa

an eating disorder characterized by binging and purging or other compensatory behaviors such as fasting or excessive exercise

purge

an inappropriate attempt to compensate for overeating through the use of vomiting,laxative abuse, or diuretics

lunage

fine,downy hair development over the body in anorexia

arrhythmia

loss of heart rhythm; cardiac arrhythmia can result in heart failure

respiration

the process of producing energy from fuels using oxygen and producing carbon dioxide and water

Vo2 Max

The maximum amount of oxygen that can be supplied at any instant in an individual

aerobic

the condition of producing energy through processes that require oxygen; having sufficient oxygen to do so

anaerobic

the condition of producing energy through processes that do not require oxygen, not having sufficient oxygen to produce energy through other processes

anaerobic threshold

the level of exercise intensity at which anaerobic energy production becomes necessary and lactic acid begins to accumulate in the muscle

immediate energy system

a system that releases energy stored in creatine phosphate for rapid maximal muscle contraction of every short duration

anaerobic glycolysis

the process that splits glucose into pyruvate and releases energy to ATP and NADH

aerobic metabolism

processes begins with the conversion of pyruvate to acetyl CoA,proceeds to the citric acid cycle, & ends with the electron transprt chain; aerobic metabolism produces NADH,H*, FADH2, ATP,C O2, and water, and requires oxygen as final electron acceptor

hyponatremia

dilution of electrolyte by overhydration- low sodium in blood

hypokalemia

low potassium in blood

Water soluble vitamins

Vitamin C thiamin, riboflavin, niacin, folic acid, vitamin b-12, b-6, biotin, and pantothenic acid

Zinc

100 enzymes present in body

involved in gene expression

necessary for cell division

Zinc Deficiency

poor growth, wound healing, maturation, immune response, poor skin and reproductive defects

Zinc Excess

lowers immune response

Iron

myoglobin

myelinsheaths

neurotransmitters

Iron deficiency

learning disabilities

hundreds of enzymes known as metalloenzymes depend on iron

structure/cofactor

detoxification of enzymes

energy release

Vitamin b-12- Colbalamin

-found in enrich bread flour

myelinsheath

activates folate

DNA synthesis

Vit b-12 Colbalamin deficiency

low intake of vit b or folate

neurological problems

neural tube defects (spina bifida)

fortification

the addition of a nutrient to a food

Potassium

major positive intarcellular ion

nerve

exchange of Na+ K

used to trigger muscle contraction

Loss of K

weakness

cardiac arrhythmia

FOUND IN: eating disorders, sweating

Sodium

exchange of Na+ and K to trigger muscle contraction

loss of NA

decrease in exercise capacity

cramping

Calcium

nerve impulses

muscle contraction

Low CA

inhibit muscle contraction

Chromium

enhances ability of insulin to bind to receptor

promotes glucose uptake

Pyridoxine (B6)

synthesis of non-essential Amino Acids

synthesis of neurotransmitters

Deficiency and Toxicity

neurological symptoms

Vitamin C

collagen

scurry (failure of collagen

neurotransmitters

high immune response

Vitamin E

fat soluble found in seeds such as grains

protects lipid components

Vitamin E deficiency

nernoysis-breaskdown of red blood cells

low immune response

Vitamin A (retinol)

precursor for beta-carotine ( better)

500 carotoneids

lycopene and lutein - protect lipid portion of cells

Vit A Deficiency

night blindness, blindness, problems with differentiation or maturation

Vitamin D

ultraviolet light

-strengthens bones

Vitamin K

found in green veggies

healthy blood function

synthesis of prothrombin ( blood clotting )

DEFICIENCY- BLOOD won't clot

Folate (folic acid)

DNA synthesis

cell division

Folate deficiency

macrocytic or megablastic anemia

B-12 (coblamin)

activate folate - pernicious anemia

Pyridoxine ( Vitamin B-6)

synthesis of hemoglobin

anemia

Phorphorous

high energy compounds ADP-ATP

Niacin

Coenzyme

energy release

DEFICIENCY - pellagra and the 4 d's

Thiamin

coenzyme

DEFIENCY :beri-beri usually alcoholics and white rice

Chromium

enhances binding of insulin to receptors

iodine

thyroxine, thyrod hormone

DEFIENCY - GOIDER ( enlargement of thyroid gland)

Contributing factors to osteoporosis

1. menopause

2. less vitamin D
