NURS 220 Study Guide - Final Guide: Monounsaturated Fat, Saturated Fat, Cheddar Cheese
Document Summary
Nutrient density a measure of the nutrients a food provides relative to the energy it provides. The more nutrients and the fewer kcalories, the higher the nutrient density. Ex: you can get about 300mgs of calcium from either 1 ounces of cheddar cheese or 1 cup of fat-free milk but the cheese delivers about twice as much food energy (kcalories) as the milk. The fat-free milk is twice as calcium dense as the cheese: it offers the same amount of calcium for the calories. Calculate kcals. from grams of protein, carbohydrate and fat. Carbohydrate: 4 kcalories of energy per gram. Fat: 9 kcalories of energy per gram: fat has a greater energy density than either carbs or protein. To calculate energy available from a food, multiply the number of grams of carbohydrates and protein by. 16 grams carbohydrate x 4 kcalories/gram = 64 kcalories. 7 grams protein x 4 kcalories/gram = 28 kcalories.
