nutrition 2 Flashcards
2 types of phospholipids
Low-density lipoproteins (LDL)
High density lipoproteins (HDL)
3 types of lipids
glycerides, sterols and phospholipids
above levels of blood glucose causes what
trigger the release of insulin which cause glucose ot move into body cells and to be stored in the liver and muscles
At room temp fats are ——– and oils are ——
solid and liquid
can lipids be dissolved in water?
no
Cholesterol should be less than
300 mg
Coffee lowers the risk of what
parkinsons disease, type 2 diabetes, stroke, and dementia
Coffee lowers the risk of what
parkinsons disease, type 2 diabetes, stroke, and dementia
complex molecules made up of amino acids.
proteins
consist of long chains of saccharides called polysaccharides
Complex carbohydrates
cooking methods affecting nutritional status
up to half of the water soluble vitamin content is lost in the cooking water of boiled vegetables
Developed to help people improve their nutritional habits but do not specify daily amounts of food and nutrients
Intended as a primary source of health information for educators, policy makers and healthcare providers
Based on scientific evidence
provide information about nutritious diet, maintaining health weight, adequate exercise and food safety
USDA DIETARY GUIDELINES FOR AMERICANS 2015-2020
direct measurement of basal metabolic rate (BMR) requires what
calorimeter - an insulates unit that measures temerpature changes of water that are produced by a fasting individual at rest
it is not used as often
Factors affecting older adults nutritional status
can lose interest in easting and decreased thirst
chronic disease may require diets in low salt, simple sugars or fat making diets unappealing
taste and smell diminish
limited mobility, vision or hearing
tooth loss
arthritis
Function of CHO’s
Supply energy for muscle and organ function
More easily and quickly digested than protein and lipids
Fuel strenuous/short-term skeletal muscle activity and provide almost all energy for the brain
Spare proteins
Increase satiety
Improve absorption of NA+ and excretion of ca
Enhance insulin excretion
Functions of Protein
Tissue building
Metabolism
Immune system
fluid balance - they attract water
acid/base balance - function as buffers
secondary energy source - when CHO’s are inadequate
greater then ____ BMI is overweight
25
how does body composition effect BMR
lean body tissue has a greater metabolic activity then fat and bone - explains why women who on average have more adipose tissue then men have a lower BMRs

how to calculate BMI
weight in kg divided by (height in meters) squared
less the ___ BMI is underweight
18.5
less the ___ BMI is underweight
18.5
Limit salt to less than
1500mg/day for AA, HTN, diabetes and chronic kidney conditions
lover levels of blood glucose causes what
triggers the release of glucagon leading to the release of glucose from storage
Most important sterol in the body
cholesterol
wax-like substance needed for the formation of cell membranes, vitamin D, estrogen and testosterone.
synthesized in the liver and also found in animal foods
Number of different amino acids that are the building blocks of most of the proteins in the human body
20
oral contraceptives affecting nutritional status
they can lower the serum level of vitamin C and several B vitamins
