What are the overall functions of the 6 classes of nutrients - Correct Answers --Provide
Calories
-For growth, development, and maintenance
-Regulate body processes
Nutrient Density - Correct Answers --Comparison of vitamin and mineral content with
the number of kcals
-Nutrient dense if food provides large amounts of a nutrient for a relatively small amount
of calories.
-EX: whole milk vs. skim milk. Skim milk is more nutrient dense because it has more
calcium and less calories
Energy Density - Correct Answers --Comparison of kcal content with weight of food
-High in kcalories but weighs very little
-Low energy dense foods usually have a lot of water content and fiber
-Energy density and body weight
-"Empty Calories"
-SoFAS = Solid Fats & Added Sugars

Function of Minerals - Correct Answers --Inorganic substances (don't contain carbon)
-Numerous functions in the body
-Major and trace minerals
-Yield no energy
Function of Water - Correct Answers --Numerous vital functions in the body
-Majority of our body (~60%)
-Recommended intake
-9-13 cups a day
-found in foods as well
-Yields no energy
What is malnutrition? - Correct Answers -any condition caused by excess or deficient
food energy or nutrient intake or by an imbalance of nutrients
-A person can be both over- and under-nourished
