1 FOOD SOURCES NUTRIENT DENSITY: click here

2 There are 28 slides In this program. Click with your mouse, to move on the next slide. Be sure to read and understand each slide before you move on….

3 WHAT IS NUTRIENT DENSITY? X Simply said: X Comparison of nutrient content to caloric content X In other words, how much nutrient is present in how many calories?

4 One way to evaluate NUTRIENT DENSITY X In this assignment XYou will compare % Daily Values of nutrients to % Daily Value of calories

5 Remember: There is a LIMITATION TO AM’T OF CALORIES X To maintain weight, calories in must equal calories out…..

6 WITH TOO MANY CALORIES X you gain weight….. X SO you are limited on calories.

7 Remember EXAMPLE: 1 bean & cheese burrito p. 158 of workbook Remember EXAMPLE: 1 bean & cheese burrito p. 158 of workbook

8 You calculated % of DAILY VALUES for vitamins & minerals for one food. EXAMPLE IN CLASS was 1 bean & cheese burrito p. 158 of workbook

9 Vitamin A (mcg) % Vitamin E (mg) % Vitamin C (mg) % Vitamin B-6 (mg) % Folate (mg) % Calculated % VITAMINS % DAILY VALUES were calculated by dividing amt of nutrient by daily value

10 Vitamin A (mcg) % Vitamin E (mg) % Vitamin C (mg) % Vitamin B-6 (mg) % Folate (mg) % Calculated % VITAMINS Vitamin A: 119/100O * 100 = 11.9 %

11 Vitamin A (mcg) % Vitamin E (mg) % Vitamin C (mg) % Vitamin B-6 (mg) % Folate (mg) % Calculated % VITAMINS Vitamin E: 0.5 / 9 * 100 = 5.5 %

12 Vitamin A (mcg) % Vitamin E (mg) % Vitamin C (mg) % Vitamin B-6 (mg) % Folate (mg) % Calculated % VITAMINS And so on….

13 VITAMINS A E C B-6 FOLATE % Daily Values Bar graph of % Daily Values

14 Sodium (mg) % Potassium (mg) % Calcium (mg) % Magnesium (mg) % Iron (mg) % Zinc (mg) % Calculated % MINERALS And so on….

15 MINERALS Sod Pot Cal Mag Iron Zinc % Daily Values Bar graph of % Daily Values

16 One way would be to evaluate the number of calories in the food. Now Consider the question: “Are these amt of nutrients high or low?”

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

18 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: 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:

19 VITAMINS A E C B-6 FOLATE % Daily Values Line = amount of calories (9.4%)

20 MINERALS Sod Pot Cal Mag Iron Zinc % Daily Values Line = amount of calories (9.4%)

21 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

22 Vitamin A (mcg) % Vitamin E (mg) % Vitamin C (mg) % Vitamin B-6 (mg) % Folate (mg) % VITAMINS compared to kcal: % kcal : 9.4 GOOD: Vitamin A Folate

23 Sodium (mg) % Potassium (mg) % Calcium (mg) % Magnesium (mg) % Iron (mg) % Zinc (mg) % MINERALS % kcal : 9.4 EXCELLENT: Sodium (because > 18.8%)

24 Sodium (mg) % Potassium (mg) % Calcium (mg) % Magnesium (mg) % Iron (mg) % Zinc (mg) % MINERALS % kcal : 9.4 GOOD: Calcium, Magnesium

25 Amt of FOOD % OF KCALORIES 1 Burrito 9.4% Vitamins: GOOD Sources Folate (10.2%) Vitamin A (11.9%) EXCELLENT Sources None Sample WORKSHEET

26 Amt of FOOD % OF KCALORIES 1 Burrito 9.4% Minerals: GOOD Sources Calcium (10.7%) Magnesium (10%) EXCELLENT Sources Sodium (24.3%) Sample WORKSHEET

27 Follow the directions on the extra credit assignment sheet. Remember late work will not receive credit.

28 HINT: You need only calculate the % of calories; all other values are the % DAILY VALUES! Summer 2002
