NUTRITION PROJECT

Hi everyone,
You'll find further info below regarding the calculation of the amount of calories for your nutrition project. Also, I know that the first website given in your hand-out is momentarily removed, so use the USDA.gov website.

All the best, Ms. Dimatulac

USRDA guidelines for consumption of caloric dense nutrients

Nutrient
Percent of calories from diet
CHO
55 %
PRO
15 %
FAT
30 %

Thus if one were to consume a 2200 calorie / day diet the number of calories per nutrient category should be:
Nutrient
Calories from diet
CHO = 2200 * 0.55
1210 calories
PRO = 2200 * 0.15
0300 calories
FAT = 2200 * 0.30
0660 calories

2200 calories

Each of the nutrients which contain calories have a specific caloric density. The caloric density for carbohydrate, protein and fat are listed .
CHO = ___4___ calories per gram ( 4 cal/g)
PRO = ___ 4___ calories per gram ( 4 cal/g)
FAT = ___9___ calories per gram ( 4 cal/g)
** Alcohol has 7 cal/g

Using the 2200 calorie diet above, the number of grams needed to be consumed to meet the USRDA requirements are as follows:
CHO = 1210 calories divided by 4 cal/g = 302.5 g
PRO = 0300 calories divided by 4 cal/g = 75 g
FAT = 0660 calories divided by 9 cal/g = 73.3 g

Interpreting Food Labels
When calculating calories from food labels , the label will provide information on the gram weight of the nutrient per serving. Note how the following values are calculated. Practice calculation:
A single serving of a food product has 31 grams of CHO, 5g of PRO, and 13g of FAT. What is the total caloric value of a single serving?
CHO = 31g * 4 cal/g = 124 calories
PRO = 05g * 4 cal/g = 020 calories
FAT = 13 g * 9 cal/g = 117 calories
TOTAL CALORIES = 261

What is the percent fat of the product ?
FAT calories / Total calories = percent fat
117 / 261 = 44.8 % fat

Is the product "low fat"? Why or why not ?
No, because in order for a food to be considered low fat , the percentage of fat in the product must fall at or below 30% of the total caloric density.

Thank you very much, Ms. Dimatulac for all your help! I really enjoyed this nutrition project because it helped me realize that eating fast food isn't as good as it tastes:) I now know to choose wisely when eating outside and to take the right amounts of nutrients such as carbohydrates, proteins, and fats that I need to live a healthy life.
