Cards

Term
Enzyme
Definition
Protein that facilitates chemical reactions but is not permanently altered in the process; biological catalyst
Term
essential amino acid
Definition
One of 9 of the 20 types of amino acids, or building blocks, that our bodies cannot manufacture and that we must consume in our foods
Term
legume
Definition
Fruit of seed of plants of the legume family. Legumes include benas, peas, peanuts, and seeds. Soy products are derived from soy beans, which are legumes
Term
carbohydrate
Definition
Memeber of a class of nutrients containing sugars and starches, which supply most of the energy that sustains normal daily activity
Term
Simple Carbohydrate
Definition
Carb made up of one ore two sugar subunits and that delivers energy in a quickly usable form. Glucose, a monosaccharide, has one sugar sub unit. Table sugar, a disaccharide, has two sugar subunits
Term
Complex Carb
Definition
Important energy-storage compound and structural building material in plants and animals. Also called polysaccharides, the complex carbs are made up of long chains of sugar molecules and deliver "timed release" energy
Term
Fiber
Definition
Indigestible carbs in the diet that speed the passage of partially digested food through the digestive tract. Fibers helps control appetite and body weight by creating a feeling of fullness without ading extra calories
Term
Glycemic Index
Definition
A measurement of the rate at which foods raise levels of glucose in the blood, and in turn, trigger the release of insulin and other blood-sugar regulators
Term
lipid
Definition
a category of compounds including fats, oils, and waxes that do not dissolve in water
Term
lipid
Definition
a category of compounds including fats, oils, and waxes that do not dissolve in water
Term
fat
Definition
a lipid such as butter, lard, and bacon grease, all of which are solids at room temperature
Term
oil
Definition
a lipid such as corn and olive oil, whish is usually a golden liquid at room temperature
Term
fatty acid
Definition
the most basic form of triglycerides
Term
triglyceride
Definition
lipid molecule made up of three fatty acid chains or "tails" attached to one glycerol "head" containing a three-carbon backbone. Common form of fats in foods and in organisms
Term
saturated fats
Definition
a lipid, usually solid fat like butter, in which most of the chains of carbon atoms are loaded with as many hydrogen atoms as the chain can carry. Suturated chains are straight, allowing them to pack together and act like a solid
Term
unsaturated fat
Definition
a lipid, usually a liquid oil, in which carbon chains lack the max load of hydrogen atoms. Unsaturated chains are kinked and cant' pack tightly , thus they can slip past each other and act like liquids
Term
monounsaturated fatty acid(MUFA)
Definition
Lipid whose fatty acid chains have jus one kinked (unsat) region. Olive oil, canolo oil, and cashew oil are high in mono-unsat fatty acids
Term
polyunsaturated fatty acid
Definition
has two or more unsat regions
Term
tranfat
Definition
an unsat liid or oil with hydrogen atoms added to cause more complete saturation and make the oil function as a solid
Term
essetial faty acid
Definition
lipid components, including linolenic acid, EPA,DHA, and linoleic acid, which the body cannot manufacture and whch we must obtain in polyunsaturated oils
Term
Omega 6-fatty acid
Definition
The fatty acids are polyunsat and have doubled bounded carbons at two sites, including one at the sixth carbon chain
Term
Omega 3- fatty acid
Definition
The fatty acids are double-bonded at three sites, including one at the third carbon along the chain
Term
lipoprotein
Definition
A lipid plus protein transopot particle that can move along easil in the bloodstream, carries triglycerides or cholesterol
Term
Cholesterol
Definition
A waxy lipid in the steroid class that is an important compnent of cell membranes and is transported in the blood by carriers called LDL and HDL. Some comes from diet, most is made in liver
Term
Low-density lipoprotein (LDL)
Definition
A form of lipoprotein sometimes called the "bad cholesterol". LDL levels rise in response to sat fats in the diet and can contribute to plaque deposits inside blood vessels
Term
High density lipoproteins (HDL)
Definition
"Good Cholestol". HDL levels rise in response to polyunsat fats and prevent and reduce plaque deposits in the blood vessels
Term
Vitamin
Definition
Organic compound in foods that we need in tiny amounts to promote growth and help maintain life and health
Term
Mineral
Definition
an element such as calcium or sodium that allows vital pysiological processes, including nerve transmission, heartbeat, oxygen delivery, and absorbtion of vitamins
Term
major mineral
Definition
a mineral neededin relatively large amounts, including sodium, calcium, phosphorus, magnesium, potassium, and chloride
Term
trace mineral
Definition
mineral needed in small amounts
Term
osteoporosis
Definition
a disease of thinning, weakend, porous, bones during which too little calcium is deposited or retained in the bones
Term
iron-deficiency anemia
Definition
disease in which the body takes in too little iron and makes too little oxygen-carrying hemoglobin
Term
dehydrated
Definition
depleted of normal, necessary levels of fluids in the body
Term
RDA's(recommended dietary allowances)
Definition
a listing of the average daily nutrient intake level for a list of vitamins and mierals that meets most people's daily needs
Term
DVs(daily values)
Definition

Term
nutrient-dense foods
Definition
food or beverage that provides a high level of nutriens and thus maximizes the nutritional value of each meal and snack consumed
Term
antioxidant
Definition
compound in foods that helps protect the body against the damaging effects of oxygen derivatives called free-radicals. Includes vitamins C and E and the yellow, red, orange, and green pigments beta carotene, lysopene, and lutein
Term
folate
Definition
form of vitamin B that is vital for spinal cord development and helps break down homocysteine as the body digests proteins
Term
