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 TO
AM’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.

One way would be to evaluate the number of
calories in the food.
NowConsiderthe question:“Are these amt of nutrients high or low?”
17
If we assume a Daily Value ofIf we assume a Daily Value of calories as 2000 calories as 2000 AND AND we determine that we determine that 1 bean & cheese burrito 1 bean & cheese burrito contains 189 kcal, then contains 189 kcal, then 189189 *100 = 9.4% of calories *100 = 9.4% of calories 2000 2000
18
This means that This means that 1 bean & cheese burrito 1 bean & cheese burrito supplies 9.4% of calories supplies 9.4% of calories and this line can be drawn and this line can be drawn across the bar graphs across the bar graphs as shown in the next two as shown in the next two slides: slides:

If we decide that: If we decide that: 1X calories: GOOD SOURCE1X calories: GOOD SOURCE& 2X calories: EXCELLENT & 2X calories: EXCELLENT SOURCE (of nutrient)SOURCE (of nutrient)Then in the burrito exampleThen in the burrito example > 9.4% = Good > 9.4% = Good > 18.8% = Excellent > 18.8% = Excellent of any nutrient of any nutrient
