QUESTIONS AND SOLUTIONS UPDATED

◉ Undernutrition
Answer: implies that the individual is not getting enough
nutrients. This can occur even if the person is consuming more
than enough calories
◉ Malnutrition
Answer: an imbalance of proper nutrients
◉ Anorexia nervosa
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
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)
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
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
Answer: inorganic material. Form body parts (teeth and bones),
maintain acid-base neutrality, regulate nerve impulses, osmotic
pressure, and electrolyte balance
◉ Major minerals
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
Answer: required in lesser amounts, and include iron, zinc,
selenium, magnesium, copper, iodine, fluorine, chromium,
molybdenum, and manganese
◉ HDL cholesterol (high density lipoproteins)
Answer: protect the body against heart disease. Often called
"good" cholesterol.
◉ LDL cholesterol (low density lipoproteins)
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
Answer: large molecules of fat and protein in the bloodstream;
how cholesterol is transported
◉ Antioxidants
, Answer: slow the aging process. Reduce cellular damage by
binding with free radicals produced during oxidation reactions
◉ Oxidation reactions
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)
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
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
