FSN 210 Lecture Notes - Lecture 2: Nutrient, Energy Density, Bacon
Document Summary
Dv: daily value: generic standard used on food labels, for ages 4 and up (except??, based on rdis and drvs daily reference values. Rdi"s: vitamins and minerals, use highest value, based on 1968 rda. Drv"s: energy nutrients- carbs, proteins and fat, based on a 2000 calorie diet. Compare the amount of vitamins, minerals, and protein, to the amount of kcal. Calculate by: divide nutrient per serving by total daily recommendation, divide kcal provided by total kcal needs, compare the two. Many low-cost nutrient dense foods: fat free milk, lean meat, beans, fruits, vegetables, while grain bagged cereals. Empty calorie foods: not nutrient dense: chips, soda, cookies, candy. Nutrient density compares the nutrients provided by a food relative to its energy content: more nutrients per kcal, holds energy (kilocalories) constant, 100kcals skim milk vs. 100kcalsl whole milk. Compares the energy content in the same quantity of food/beverage: holds quantity (volume/weight) constant, example: 8oz skim milk vs. 8oz whole milke.
