Table D4-4. Examples of the Many Varying patterns of Fats, Fatty Acids, and Carbohydrates Possible

Protein level can be determined by difference [total energy percent – (total fat percent + carbohydrate percent) = protein percent]

Total Fat SFA NUFA PUFA CHO* MUFA Constant; Total Fat Constant Percent of Total Energy 35 9 20 6 50 35 5 20 10 50 MUFA constant, total fat constant at 20 percent; other fatty acids vary 20 5 10 5 65 20 4 10 6 65 Total fat constant at 35 percent, MUFA vary; other fatty acids vary 35 7 23 5 50 35 8 18 9 50 Total fat constant at 20 percent, MUFA vary; other fatty acids vary 20 7 8 5 65 20 5 10 5 65 Total fat varies, MUFA constant; other fatty acids vary 33 9 14 10 52 22 3 14 5 52 Total fat, CHO, & MUFA vary; other fatty acids constant 30 5 18 7 55 20 5 8 7 65

SFA = saturated fatty acids

MUFA = MUFAs

PUFA = PUFAs

CHO = carbohydrate

*Protein held constant at 15 percent of energy for these calculations. Variations in the percentage of energy from protein would change the percentage of energy from carbohydrates.
