FSHE 185: Skills Review
None of the self-assessments are submitted.

Students need developed online study skills as well as a basic understanding of math and chemistry to be successful in the class. Get Ready for Nutrition, an online review primer, will help you to assess your study skills as well as your math and chemistry knowledge.

Click <http://wps.aw.com/bc_garrett_grfn_1/> to access the review materials. Taking the 'Diagnostic Test' can be a helpful tool to assess areas to review. Choose 'Study Skills', 'Basic Math', or 'Chemistry' from the menu bar at the top of the page. Scan the resources and choose the areas that you feel will be useful.

Typical Nutrition Math Applications

Percentages: The term percent (%) refers to a part of the total when the toal represents 100 parts.

Examples:
What is 10 % of 100?
.10 X 100 = 10

What is 5% of 20?
.05 X 20 = 1

What is 15% of 60?
.15 X 60 = 9

What percent of 16 is 6?
6/16 = .375 X 100 = 37.5%

What percent of 99 is 3?
3/99 = .03 X 100 = 3%

Application:
Calculate the number of kcal you consume in fat for the day if you are allowed no more than 30% fat of a 2000 kcal diet.

If you consumed 1500 kcals, of which 900 were from carbohydrates, what percent of your total kcals comes from the carbohydrates?

Conversions: Use the following information paying close attention to units.

Liquid/Volume
3 teaspoons (tsp) = 1 tablespoon (T)
16 T = 1 cup
4 c = 1 quart (qt)
4 qts = 1 gallon (gal))
2 T = 1 ounce (oz)
8 oz = 1 cup
16 oz = 1 pint (pt)
32 oz = 1 qt

Metric/Household
1tsp = 5 milliliters (ml)
1 T = 15 ml
1 c = 240 ml
1 qt = 960 ml
(app 1000 ml or 1 liter)
1 fluid ounce (fl oz) = 30 ml
1 oz = app 30 grams (g)

Weight
1 milligram (MG) = 1000 micrograms (mcg)
1 g = 1000 mg
1 kilogram (kg) = 1000 g
454 g = 1 pound (lb)
1 kg = 2.2 lb

Application:
How many 2 T servings are in a quart jar of mayonnaise?

Figure the weight of a person in kg if the person weighs 150 lbs.

Calculating Percent of kcal from Grams of Various Macronutrients:

This calculation is made for individual foods as well as meals, or total daily food intake. You must know the total kcal in the food, meal, or daily intake and the amount of the various macronutrients and/or alcohol (usually given in grams).

Example: a meal has 878 kcal with 26 g fat, 110 g carbohydrate, 30 g protein, and 12 g alcohol. What is the percent kcal from fat: 9 kcal/g X 26 g fat = 234 kcals from fat
234 kcal fat/878total kacl = .2665 = .27
.27 X 100 = 27% kcal from fat

Application:
Calculate the percent kcal from carbohydrate, protein, and alcohol.

Calculating Grams of Macronutrients from Percent of kcal:

Example: using a daily intake of 2200 kcal
30% of kcal from fat .30 X 2200 total kcal = 660 kcal from fat
660 kcal fat/9 kcal per gram = 73 g fat

Application:
If the above 2200 total kcal diet contained 40% carbohydrate, 20% protein, 10% alcohol, calculate the grams from carbohydrate. protein and alcohol.
