◉ Nutrient Classification: Macronutrients.
Answer: Carb, Protein, Lipids, Water
◉ Nutrient Classification: Micronutrients.
Answer: B Vitamins, Vitamin C, vitamin A, Vitamin D, Vitamin E,
Vitamin K, Calcium, Iron
◉ Nutrient Classification: Inorganic.
Answer: Minerals, Water
◉ Nutrient Classification: Organic.
Answer: Carbohydrates, Lipids, Protein, Vitamins
◉ Amount of Energy Carbohydrates Provides.
,Answer: 4 kcals
◉ Amount of Energy Protein Provides.
Answer: 4 kcals
◉ Amount of Energy Fat Provides.
Answer: 9 kcals
◉ Amount of Energy Alcohol Provides.
Answer: 7 kcals
◉ Nutrient Density.
Answer: A measure of nutrient a food provides compared to its
energy content i.e.: broccoli vs. french fries, low-fat milk vs.
sweetened iced tea.
Other nutrient dense foods: fruit/nut trail mix, fresh fruit, baked
chips, oatmeal raisin cookies
◉ Balance Study.
Answer: The type of nutrition study that focuses on the amount of
nutrient consumed compared to the nutrient leaving the body
,◉ Epidemiological Study.
Answer: Observing relationships between diet, health and disease
patterns in different food populations
◉ Case Control Studies.
Answer: Compares individuals with a particular condition to similar
individuals without the condition
◉ Depletion-Repletion Studies.
Answer: The nutrient is eliminated in the diet until deficiency
symptoms appear. Then the nutrient is added back to the diet to a
level which may eliminate the symptoms
◉ A nutrition supplement or product is considered credible if....
Answer: Results were based on scientific studies that used the
proper controls, adequate experimental subjects, and the data was
quantifiable
◉ Adequate Intake (AI).
Answer: Established due to insufficient scientific date to establish an
EAR and calculate an RDA
◉ Estimated Average Requirements (EARS).
, Answer: Amount needed to meet 50% of people in the same gender
and life-stage group
◉ Recommended Dietary Allowances (RDA).
Answer: Intakes that meet the needs of nearly all (97-98%) of
individuals in each gender and life-stage group
◉ Tolerable Upper Intake Levels (ULs).
Answer: Maximum daily intake that is unlikely to pose a risk of
adverse health effects to almost all individuals in a specific life-stage
and gender group
◉ Differences between the energy recommendations AMDR and
EER.
Answer: Estimated Energy Requirements (EERs): average energy
intakes predicted to maintain body weight by calculating the amount
of kilocalories
Acceptable Macronutrient Distribution Ranges (AMDRs): Intakes of
macronutrients (carbohydrate, protein, and fat) are expressed in %.
Expressed as a % of total energy intake
◉ Dietary Guidelines.
