Be sure to read and understand each slide before you move on….

### WHAT IS NUTRIENTDENSITY?

• Simply said:

• Comparison of nutrient content to caloric content

• In other words, how much nutrient is present in how many calories?

### One way to evaluateNUTRIENTDENSITY

• In this assignment

• You will compare % Daily Values of nutrients to % Daily Value of calories

### Remember: There is a LIMITATION TOAM’T OF CALORIES

• To maintain weight, calories in must equal calories out…..

### WITH TOO MANY CALORIES

• you gain weight…..

• SO you are limited on calories.

## You calculated % ofDAILY VALUES forvitamins & minerals for onefood.EXAMPLE IN CLASS was 1 bean & cheese burritop. 158 of workbook

Calculated % VITAMINS

Vitamin A (mcg) 1000 119 11.9%

Vitamin E (mg) 9 0.5 5.5%

Vitamin C (mg) 60 1 1.7%

Vitamin B-6 (mg) 2 0.12 6 %

Folate (mg) 400 41 10.2%

% DAILY VALUES

were calculated by dividing amt of nutrient by daily value

Calculated % VITAMINS

Vitamin A (mcg) 1000 119 11.9%

Vitamin E (mg) 9 0.5 5.5%

Vitamin C (mg) 60 1 1.7%

Vitamin B-6 (mg) 2 0.12 6 %

Folate (mg) 400 41 10.2%

Vitamin A:

119/100O * 100 =

11.9 %

Calculated % VITAMINS

Vitamin A (mcg) 1000 119 11.9%

Vitamin E (mg) 9 0.5 5.5%

Vitamin C (mg) 60 1 1.7%

Vitamin B-6 (mg) 2 0.12 6 %

Folate (mg) 400 41 10.2%

Vitamin E:

0.5 / 9 * 100 =

5.5 %

Calculated % VITAMINS

Vitamin A (mcg) 1000 119 11.9%

Vitamin E (mg) 9 0.5 5.5%

Vitamin C (mg) 60 1 1.7%

Vitamin B-6 (mg) 2 0.12 6 %

Folate (mg) 400 41 10.2%

And so on….

Now

Consider

the question:

“Are these amt of nutrients

high or low?”

One way would be to evaluate the number of calories in the food.

If we assume a Daily Value of calories as 2000 AND we determine that 1 bean & cheese burrito contains 189 kcal, then189 *100 = 9.4% of calories 2000

This means that 1 bean & cheese burrito supplies 9.4% of calories and this line can be drawn across the bar graphs as shown in the next two slides:

VITAMINS

Line =

amount of calories

(9.4%)

% Daily Values

A E C B-6 FOLATE

MINERALS

Line =

(9.4%)

% Daily Values

Sod Pot Cal Mag Iron Zinc

If we decide that: 1X calories: GOOD SOURCE& 2X calories: EXCELLENT SOURCE (of nutrient)Then in the burrito example > 9.4% = Good > 18.8% = Excellent of any nutrient

VITAMINS compared to kcal:

Vitamin A (mcg) 1000 119 11.9%

Vitamin E (mg) 9 0.5 5.5%

Vitamin C (mg) 60 1 1.7%
