RDA: Recommended Daily Allowance
|
Levels of intake of essential nutrients based on age & gender that are judged to be adequate to meet the known needs of practically all healthy people
|
|
DRI: Dietary Reference Intakes
|
A revised, more detailed version of the RDAs and refer to three types of reference values: EAR (Estimated Average Requirement), UL (Tolerable Upper Intake Level), and AI (Adequate Intake)
|
|
EAR: Estimated Average Requirement
|
one of the DRIs that indicates an adequate intake in 50% of an age and gender specific group
|
|
UL: Tolerable Upper Intake Level
|
one of the DRIs; the maximum intake that is unlikely to pose a risk of adverse health effects to almost all individuals in an age and gender specific group
|
|
AI: Adequate Intake
|
one of the DRIs; used when an RDA cannot be based on EAR; is is the recommended intake level, that based on research, appears to be sufficient for good health
|
|
Complex Carbohydrates
|
Long chains of glucose molecules including GLYCOGEN and starch
|
|
Simple Carbohydrates
|
Sugars; Short chains of glucose molecules
|
|
High Viscosity Fiber
|
aka soluble fiber; slow gastric emptying and help increase feelings of fullness
|
|
Low Viscoity Fiver
|
aka insoluble fiber; increase fecal bulk and provide a laxative effect
|
|
Saturated Fatty Acids
|
Chains of hydrocarbons with NO DOUBLE BONDS between carbon atoms; they are stable, typically solid at room temperature; found in meat, full fat dairy & tropical oils
|
|
Unsaturated Fatty Acids
|
Chains of hydrocarbons that contain 1 + DOUBLE BONDS between carbon atoms, are fairly unstable, and typically a liquid at room temperature; found in olive, canola, peanut, corn, safflower & soybean oil, cold water fish
|
|
Complete Protein
|
food source that contains all of the (8-10) essential amino acids, such as any animal product
|
|
Incomplete Protein
|
food source that does not contain all of the essential amino acids; must be eaten in combination; from plant sources
|
|
Vitamin B12
|
Aids in cell development, functioning of the nervous system and the metabolism of protein and fat
|
|
Vitamin K
|
Essential for blood clotting functions;fat soluble; Newborns are at risk of being deficient in this nutrient because it does not cross placenta & negligible in breast milk
|
|
Choline
|
vitamin that is essential for liver function
|
|
Thiamin
|
Helps body release energy from carbohydrates during metabolism
|
|
Vitamin D
|
Aids in bone and tooth formation; small amounts of sunlight exposure induce the body to make it
|
|
Pantothenic Acid
|
Helps release energy from fats and vegetables; one of the B vitamins
|
|
Vitamin E
|
Protects blood cells, body tissue, and essential fatty acids from destruction in the body; toxicity of this nutrient is especially hazardous for people taking anti clotting Rx such as coumadin
|
|
Carotene
|
Formation of maintenance of the skin, hair, mucous membranes
|
|
Sucrose
|
the result of binding together of glucose and fructose
|
|
Glycogen storage
|
90 grams in the liver; 150 grams stored in muscle
|
|
LDL Cholesterol
|
Low density lipoprotein; Increased by saturated fat intake; aka "bad" cholesterol
|
|
Antibodies
|
used to fight infection; manufacture by proteins
|
|
Hyponatremia
|
electrolyte imbalance caused by excessive fluid intake
|
|
Bio-availability
|
The degree to which a mineral can be used by the body
|
|
Oxidation
|
damage causing process that is the result of a cell's chronic exposure to oxygen
|
|
Dietary Supplement and Health & Education Act
|
Dictates supplement production, marketing and safety guidelines in US
|
|
Zinc
|
Important in the development of the reproductive system and aids in healing
|
|
Iodine
|
Component of the hormone thyroxine, which control metabolism
|
|
Calcium
|
Essential for strong bones, teeth & muscle tissue and helps regulate heart beat; a deficiency in childhood and adolescence can lead to decreased peak bone mass and suboptimal bone strength
|
|
Selenium
|
Protects body tissues against oxidative damage
|
|
Fluoride
|
Stimulates bone formation and inhibits or even reverses dental caries
|
|
Magnesium
|
Maintains acid/base balance and is important in metabolism or carbohydrates, minerals and sugar
|
|
Iron
|
Important for hemoglobin formation and improves blood quality
|
|
Chromium
|
Involved in glucose metabolism and increases the effectiveness of insulin
|
|
When is thirst an inappropriate gauge for hydration?
|
Infants, elderly/ill, hospitalized patients, vigorously exercising athletes
|
|
Phosphorous
|
Like calcium, this nutrient plays a role in the mineralization of bones and teeth
|
|

|
Substance in plants that improves health and reduces risk for disease but is not required for normal functioning
|
|
Sodium
|
Excessive consumption of this electrolyte can contribute to hypertension and osteoporosis
|
|
Iron
|
This nutrient can be stored in the body for suture use as the protein complex ferritin
|
|
Iodine
|
Deficiency or toxicity of this nutrient can cause goiter
