  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 NUTRIENTDENSITY? • Simply said: • Comparison of nutrient content to caloric content • In other words, how much nutrient is present in how many calories?

  4. One way to evaluateNUTRIENTDENSITY • In this assignment • You will compare % Daily Values of nutrients to % Daily Value of calories

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

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

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

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

  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% % DAILY VALUES were calculated by dividing amt of nutrient by daily value

  10. 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 %

  11. 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 %

  12. 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….

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

  14. Calculated % MINERALS Sodium (mg) 2400 583 24.3% Potassium (mg) 3500 248 7.1% Calcium (mg) 1000 107 10.7% Magnesium (mg) 400 40 10 % Iron (mg) 18 1.2 6.7% Zinc (mg) 15 0.8 5.3% And so on….

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

  16. 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.

  17. 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

  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:

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

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

  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. 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% Vitamin B-6 (mg) 2 0.12 6 % Folate (mg) 400 41 10.2% % kcal : 9.4 GOOD: Vitamin A Folate

  23. MINERALS Sodium (mg) 2400 583 24.3% Potassium (mg) 3500 248 7.1% Calcium (mg) 1000 107 10.7% Magnesium (mg) 400 40 10 % Iron (mg) 18 1.2 6.7% Zinc (mg) 15 0.8 5.3% % kcal : 9.4 EXCELLENT: Sodium (because > 18.8%)

  24. MINERALS Sodium (mg) 2400 583 24.3% Potassium (mg) 3500 248 7.1% Calcium (mg) 1000 107 10.7% Magnesium (mg) 400 40 10 % Iron (mg) 18 1.2 6.7% Zinc (mg) 15 0.8 5.3% % kcal : 9.4 GOOD: Calcium, Magnesium

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

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

  27. Follow the directions on theextra credit assignment sheet.Remember late work willnot receive credit.

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