Q: How would you define the basic role of nutrition for the human body?
A: Nutrition is the process of supplying the body with essential substances and
elements required to fuel daily biological functions and physical activities. ✔✔
Q: What is the specific distinction of undernutrition?
A: Undernutrition occurs when a person lacks sufficient essential nutrients.
Notably, this condition can manifest even in individuals who consume an
adequate or excessive number of calories but lack nutrient density in their diet.
✔✔
Q: What does the term malnutrition encompass?
A: It refers to a state of physical imbalance resulting from either a deficiency, an
excess, or a disproportionate intake of specific nutrients. ✔✔
Q: What are the clinical characteristics and risks of Anorexia Nervosa?
A: Though the name implies a lack of appetite, individuals typically experience
hunger but suppress it due to an intense, irrational fear of weight gain. It is
marked by self-starvation, obsessive food rituals, and excessive exercise. In
women, it often leads to the cessation of menstrual cycles and, if left untreated,
can lead to organ failure or death. ✔✔
Q: How is Bulimia Nervosa typically identified in a patient?
,A: This disorder is defined by cycles of binge eating—consuming large volumes of
food in a short window—followed by compensatory "purging" behaviors. These
behaviors often include self-induced vomiting, the misuse of laxatives or diuretics,
or compensatory periods of strict 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 -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 -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 -ANSWER ✔✔proteins that are lacking one or more of the
essential amino acids
Glycogen -ANSWER ✔✔the polysaccharide form in which glucose is stored in the
liver
Glucose -ANSWER ✔✔simple sugar. The only source of energy that brain cells use
to function
