AAFCS PrePac Exam with 100% Correct
Solutions
Recommended calories from carbs - ANS-45 to 65 percent of calories
Carbohydrate subgroups - ANS-Glucose -- used immediately for energy, stored in the
liver and muscles as glycose or (if excess) stored in adipose tissue as fat
Simple carbs - ANS-easily digested and absorbed into bloodstream
Complex carbs - ANS-involve more complex digestive process and provide steady
stream of glucose
Soluble fiber - ANS-dissolves in water to form a gel
Insoluble fiber - ANS-does not break down, found in barley, legumes, some fruits and
vegetables. Slows digestion, promoting nutrient absorption
Proteins - ANS-long chains of amino acids
non-essential amino acids - ANS-can be made by the body
essential amino acids - ANS-Amino acids that are needed, but cannot be made by the
body; they must be eaten in foods
complete proteins - ANS-proteins that contain all nine of the essential amino acids
Potassium - ANS-Component in heart rhythm, muscle contraction and blood pressure.
Deficiency can cause muscle cramping and and fluid imbalance
Sodium - ANS-assists in fluid balance and muscle contraction
thermic effect of food - ANS-digestion increases after meal; can account for 10-15
percent of energy expenditure; energy cost of food is highest for protein; lower for carbs
and fat
thermic effect of physical actvity - ANS-5-40% of daily energy expendiure; highly
variable; may derease appetite slightly
resting/basal metabolic rate - ANS-Energy expended by body to sustain living
processes
