Nutrition
CORRECT ANSWER:
provides the body with the nutrients it needs to perform its daily
tasks
Undernutrition
CORRECT ANSWER:
implies that the individual is not getting enough nutrients. This can
occur even if the person is consuming more than enough calories
Malnutrition
CORRECT ANSWER:
an imbalance of proper nutrients
Anorexia nervosa
CORRECT ANSWER:
literally means loss of appetite, but this is a misnomer: A person with
this is hungry, but denies the hunger because of an irrational fear of
becoming fat. Self-starvation, food preoccupation and rituals,
compulsive exercising, and often an absence of menstrual cycles in
,women.
Untreated, can be fatal.
Bulimia
CORRECT ANSWER:
characterized by recurring periods of binge eating, during which
large amounts of food are consumed in a short period of time
followed by purging (through self-induced vomiting, abuse of
laxatives and/or diuretics) or periods of fasting
Binge eating disorder (BED)
CORRECT ANSWER:
episodes of binge eating characterized by eating rapidly, eating
large amounts of food even when not feeling hungry, and feeling
guilty or depressed after overeating.
Obesity
CORRECT ANSWER:
15 to 20 percent above normal weight. Poor dietary patterns; include
increased intake of sugars in sweetened soft drinks, foods, and
meals of high energy, low nutrient density, and large portion sizes.
At risk for serious health problems such as type 2 diabetes,
hypertension, heart disease, stroke, and some types of cancer.
Minerals
CORRECT ANSWER:
inorganic material. Form body parts (teeth and bones), maintain
acid-base neutrality, regulate nerve impulses, osmotic pressure, and
electrolyte balance
Major minerals
CORRECT ANSWER:
,needed by the body:
• calcium—milk, cheese, sardines, salmon, green vegetables
• phosphorus—milk, cheese, lean meat
• potassium—oranges, bananas, dried fruits
• sulfur—eggs, poultry, fish
• sodium—table salt, beef, eggs, cheese
• chloride—table salt, meat
• magnesium—green vegetables, whole grains
Trace minerals
CORRECT ANSWER:
required in lesser amounts, and include iron, zinc, selenium,
magnesium, copper, iodine, fluorine, chromium, molybdenum, and
manganese
HDL cholesterol (high density lipoproteins)
CORRECT ANSWER:
protect the body against heart disease. Often called "good"
cholesterol.
LDL cholesterol (low density lipoproteins)
CORRECT ANSWER:
most cholesterol in the blood is of this type. Often referred to as the
bad cholesterol. high levels in the blood increases the risk of fatty
deposits forming in the arteries, which in turn increases the risk of a
heart attack
Lipoproteins
CORRECT ANSWER:
large molecules of fat and protein in the bloodstream; how
cholesterol is transported
Antioxidants
, CORRECT ANSWER:
slow the aging process. Reduce cellular damage by binding with free
radicals produced during oxidation reactions
Oxidation reactions
CORRECT ANSWER:
the energy-yielding reactions in which either an oxygen atom adds
an electron to or a hydrogen atom removes an electron from a
substrate (a group of atoms or molecule)—the net result is a
substrate that has had a partial or complete loss of a negatively
charge particle, an electron. Two partially charged atoms or groups
of atoms, one positively charged and the other negatively charged,
now exist
Free radical (Oxidant)
CORRECT ANSWER:
any atom or group of atoms that has an unpaired electron. Because
electrons typically function in pairs, these are very prone to binding
to other substrates in an effort to regain this paired status. When this
happens in the human body, there is potential for a great deal of
damage.
Carbohydrates
CORRECT ANSWER:
produce 4 calories of energy per gram. Found in foods as
monosaccharides, disaccharides, and polysaccharides. Sources
include fruits, vegetables, pasta, and rice which consist of simple
sugars and starches
Protein
CORRECT ANSWER:
produce 4 calories of energy per gram. Sources include meats and
milk. Composed of 8 essential(provided by the diet) and 12
