Exam 1 intro Flashcards
Essential nutrient
substance required for life that must be consumed
Nonessential nutrient
Substance that is biologically active but not required
6 classes of nutrients
CHO, protein, vitamins, minerals, water, fats
What do CHO’s do for the body?
4kcal/g. most immediate source of energy
What do proteins do for the body?
4kcal/g. part of the structure of our muscles, and individual cells. Part of cartilage that cushion joints.
What do fats do for the body?
9kcal/g. Fuel our activities and major form of stored energy.
Is diet always the cause of disease?
No, although it can be linked with the two major diseases in the US, cancer and heart disease.
Malnutrition
Over or under nourished.
Standards focused on science
DRI’s and dietary guidelines
Standards focused on the consumer
Myplate, dietary values
Energy per gram value of alcohol?
7kcal/g
What does the line in the middle of the graph represent?
EAR (estimated average requirements)
What does the line at the end of the curve represent
RDA
What does the line not placed on the curve represent?
UL
What do the levels set by the RDA represent?
The levels represent the amounts that most healthy people should consume on average
What percent of the population does the RDA meet their nutrient need?
97%
Are the RDA world standards or just for the US?
Just for the US
Does eating over the UL always lead to a toxicity of that nutrient?
No
What precautions might you give to someone wanting to assess their nutrient intake from a 1 or 2 day food record?
Should have at least 7 days worth of data to compare to RDA’s
What are the AMDR ranges?
Protein: 10-35%
CHO: 45-65%
Fat: 20-35%
What are dietary guidelines?
A set of diet and lifestyle recommendations designed to promote health and reduce the risk of overweight and chronic disease on the US. Designed for ages 2 and up.
What are the food groups of Myplate?
Fruits, veggies, grains, protein, dairy oils?
What determines what food group a specific food goes into?
foods that are rich in that nutrient
What determines how many servings an individual is recommended to eat in a day from each food group?
The number of calories they require
How do the myplate and daily values incorporate the concepts within DRI’s and the dietary guidelines
Foods are put into groups based on nutrients (RDA’s) and then put into proportions (DG)
Daily value
a reference value for the intake of nutrients used on food labels to help consumers see how a given food fits into their overall diet
What precautions might you give about using food label standards to assess personal nutrient needs?
May overestimate the amount of a nutrient needed for some population groups
