CORRECT ANSWERS COMPLETE SECURITY

●● 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
