Question 9

an example of a nutrient with an AI:

Answer 10

inadequate

Question 11

Answer 11

increase your intake

Question 12

If your intake is between the RDA and the UL, then it is probably:

Answer 12

adequate

Question 13

EER:

Answer 13

average energy intake that is predicted to maintain a healthy weight.

Question 14

is EER generous?

Answer 14

no

Question 15

AMDR values :

Answer 15

Carbs: 45-65% of total energy intake • Fat: 20-35% of total energy intake • Protein: 10-35% of total energy intake

Question 16

DV are necessary because:

Answer 16

DRIs are too specific

Question 17

Answer 17

2006 in canada

Question 18

Question 19

Without the bran and germ:

Answer 19

about 25% of a grain’s protein is lost, along with its nutrients.

Question 20

The bran:

Answer 20

the multi-layered outer skin of the edible seed. It is fibre-rich.

Question 21

The germ:

Answer 21

the embryo. It has the potential to sprout into a new plant. This potential vanishes when you eat it! The germ ontains vitamins.

Question 22

The endosperm

Answer 22

the embryo’s (the germ’s) food supply, which provides essential energy to the germ so it can sprout – set out some roots and begin photosynthesis. The endosperm is by far the largest portion of the seed. It contains mostly starch.

Question 23

Health Canada defines whole grains as:

Answer 23

the dried seeds of cereal species:

Question 24

Whole grains must contain:

Answer 24

all of the original germ, bran and endosperm.

Question 25

Enrichment:

Answer 25

addition of vitamins and minerals to food products to replace those lost during processing or refinement

Question 26

Fortification:

Answer 26

addition of supplementary nutrients to food

Question 27

Why are beans, peas, lentils and peanuts all grouped together?

Answer 27
