Cards

Term
Essential Fatty acids
Definition
Body does not make these or does not make enough so they must be in diet.
Term
Lipids
Definition
are insoluble in water
Term
Cholesterol
Definition
from animal sources only
Term
Cholesterol HDL's
Definition
(heart healthy)transport cholesterol to liver
Term
Cholesterol LDL's
Definition
(lethal) are transporting cholesterol into body
Term
Hydrogenating Vegetable Oils
Definition
can produce trans-fat
Term
Fats
Definition
saturated with hydrogen
unsaturated have double bonds
Term
melting point
Definition
temperature where solid becomes liquid (shorter chains and more unsaturation make product more fluid)
Term
oxidative rancidity
Definition
strong off-flavor
Term
unsaturated fats
Definition
more than saturated ones

tenderization
Term
aeration
Definition
creaming of solid plastic fat
Term
crystallization
Definition
texture, solidification
Term
emulisification
Definition
fats suspended in water
Term
flavor
Definition
contributor and carrier

softer crumb structure
Term
chemical reactions
Definition
hydrogenation
hydrolysis
Term
hydrogenation
Definition
stability and solidification
Term
hydrolysis
Definition
breakdown
Term
fat replacers
Definition
decreased fat may mean higher water content and safety concerns
Term
metabolism
Definition
chemical reactions in body building and breaking compounds
energy is stored in bonds
human bodies like to burn carbohydrates
Term
Micronutrients
Definition
vitamins
minerals
-mega doses may cause toxicity
Term
vitamins
Definition
small but vital organic compounds
-water soluble (B&C)
-fat soluble (A,D,E,K)
Term
Minerals
Definition
inorganic, but make things happen
Term
Vitamen D
Definition
can be made in skin or is common in fish oils and egg yolks
Helps us absorb and utilize calcium
Term
Thiamine
Definition
helps convert carbohydrate to enery and maintain healthy nerves
deficiency -beriberi
sources-whole grains,legumes, meats, nuts
Term
Vitamens
Definition
Fat soluble vitamens more stable than water soluble ones to heat, light and oxidation
Term
Vitamen E
Definition
powerful antioxidant vitamin protecting body membranes from oxidation damage
source is vegetable oils
Term
Riboflavin
Definition
converts foods to energy and helps make red blood cells
sources: dairy
Deteriorates in sunlight, UV light
Term
Vitamin A
Definition
Beta carotene can make Vitamin A if needed, but not toxic if not needed.
Term
Vitamin K
Definition
functions in blood clotting
sources: foods like broccoli and cabbage and bacteria in the colon
may interfere with action of coumadin
Term
Niacin
Definition
converts food to energy
Deficiency is rare but may develop Pellegra (4 D's-dermatitis, diarrhea, dementia and death)
Reduces blood cholesterol
Toxicity is Niacin Flush
Term
Pantothenic Acid
Definition
helps generate energy and immune system
Deficiency rare
Toxicity rare
Term
Folate
Definition
helps form red blood cells and DNA
Deficiency in pregnant woman, may cause baby to have anencephaly (lack of brain) or spina bifida (open spine)
Term
Pyradoxine
Definition
Forms red blood cells, antibodies, insulin
sources many foods especially animal sources.
Term
Biotin
Definition
sources: eggs, legumes, meats, nuts
Term
Food Bioactives
Definition
these are non-essential bio-molecules that modulate metabolic processes
plant based foods have the most bioactive molecules
Term
Vitamin B12
Definition
Forms red blood cells and DNA and maintains nerves
Defiency: anemia
Term
Vitamin C
Definition
antioxidant, strengthens collagen connective tissue
sources: citrus fruit and fresh vegetables and fruits
Deficiency: scurvy causing pinpoint
Term
Bioactives
Definition
carotenoids - are nontoxic unlike preformed Vitamin A
Often found in orange and green foods.
Lycopene- found predominately in tomatoes is good for eyes and helps prevent cancer
Tocopherols-(Vitamin E) are powerful antioxidants preventing damage to cell membranes
Term
prebiotics
Definition
fiber that is beneficial to growth of helathy intestinal bacteria
Term
probiotics
Definition
healthy bacteria in the colon
