EXAM 2024-2025 ACTUAL EXAM TEST BANK 300+ QUESTIONS AND CORRECT
DETAILED ANSWERS
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 nonessential(synthesized by the
body) amino acids. Perform many functions including building cells and tissues, forming blood
and enzymes, and fighting infection.
means primary, and no organism can live, and almost no biological process can take place,
without it
Lipids - correct answer produce 9 calories of energy per gram. Organic compounds that do not
readily dissolve in water; based on their solubility, they are classified into triglycerides (more
commonly known as fats), phospholipids, and sterols

Incomplete protein - correct answer proteins that are lacking one or more of the essential
amino acids
Glycogen - correct answer the polysaccharide form in which glucose is stored in the liver
Glucose - correct answer simple sugar. The only source of energy that brain cells use to
function
Triglycerides (Fats) - correct answer Solid at room temperature. Group of chemical compounds
that contain fatty acids, often in very long strands. Most concentrated source of energy in the
diet. Provides much of the stored energy of the body. Insulate body organs against changes in
environmental temperature. Protect the organs and underlying tissues by acting as a shock
absorber.
Water - correct answer essential component of body structure. Second only to oxygen in
importance to body functioning. Acts as a solvent for minerals and other physiologically
important compounds. In the body, it transports nutrients to and waste products from the cells
and helps regulate body temperature. Comes from fluids and solids in the diet and also is
produced by the metabolic processing of energy nutrients within the tissues
Oils - correct answer liquid at room temperature.
Vitamins - correct answer organic compounds required by every part of the body to maintain
health and prevent disease. Classified as either fat-soluble or water-soluble. Do not become
part of the body. Only small amounts are needed, but must be provided by the diet because the
body is not able to synthesize them in the required quantities for proper nourishment and body
function. Foster growth, promote the ability to produce healthy offspring, maintain health, aid
in the normal function of the digestive tract and appetite, and help maintain immune system
functions.
Fat-soluble vitamins - correct answer found in the fatty parts of food and body tissues. Stored
in the body until needed, so it is not necessary to consume them every day. Transported by
lipids through the body; A, D, E, and K
Vitamin A - correct answer important in promoting growth and health of body tissues as well
as enhancing the function of the immune system. Enhances vision by helping the retina
function properly, permitting us to distinguish between light and shade and to see various
colors distinctly. A form of this is used by dermatologists to treat acne and other skin disorders.
Overdoses may result in yellowish, dry, scaly skin and dry, irritated eyes
Vitamin D - correct answer essential for calcium absorption and thus is needed to prevent and
cure rickets(deficiency disease in which bones fail to harden)
Vitamin E - correct answer an activator in certain enzyme reactions, and it protects vitamins A
and C from being used up too quickly
