on age, sex, height, weight, and physical activity.

Non-nutritive sweeteners - ANS... -Sweeteners that provide no calories.

Insoluble fiber - ANS... -A type of fiber that helps the digestive tract hold water.

Mechanical digestion - ANS... -The physical breakdown of food into smaller
pieces.


Recommended daily intake of vitamin C - ANS... -125 mg/day is recommended for
a patient who smokes approximately half a pack of cigarettes per day.

Thiamin deficiency - ANS... -Deficiency of thiamin can cause symptoms of
constipation, poor appetite, fatigue, and malaise.

Riboflavin sources for vegetarians - ANS... -Milk, soybeans, and enriched cereal
can increase riboflavin in the diet.

Vitamin D toxicity signs - ANS... -Hypercalcemia and hypercalciuria indicate that
a patient is experiencing vitamin D toxicity.

failure? - ANS... -1500 mg/day

Which statement defines resting energy expenditure (REE)? - ANS... -It is the
amount of energy (in kcal) needed by the body for the maintenance of life at rest
over a 24-hour period.

Calculate the total energy expenditure (TEE) using Mifflin-St. Jeor formula for a
patient who is mildly obese. - ANS... -1685 kcal/day; Patient height in inches: (5
feet x 12 in/ft) + 4 in = 64 in. Patient's height in cm: 64 in x 2.54 cm/in = 162.56.
Patient's weight in kg: 178 lbs / 2.2 lbs/kg = 80.91. Multiply the patient's height,
weight, and age to the respective numbers in the formula before adding height and
weight together and subtracting the age total and 161. Then complete the formula
by multiplying the total by the PA. TEE = [(10 x 80.91) + (6.25 x 162.56) - (5 x
52) - 161] x 1.2 = 1685 kcal/day.
