NUTRITION Flashcards
Sum of all interactions between an organism and the food it consumes
Nutrition
Organic and inorganic substances found in the foods for body functioning
Nutrients
The nutrien content of a specified food
Nutritive value
3 essential Nutrients
Water
Carbo fats and proteins
Vitamins and minerals
Neded in large amounts in the body (hundreds of gram)
Macronutrient
Needed in small amounts to metabolize the energy providing nutrients
Micronutrients
Carbohydrates is composed of
Carbon, Hydrogen and Oxygen
2 types of carbohydrates
Simple ( SUGARS) complex ( STARCH AND FIBERS)
High suga content and solid fat foods
EMPTY CALORIES
Simplest of all CHO water soluble and produced by both plants and animals
Sugar
Single molecule, glucose fructose galactose
MONOSACCHARIDES
Double molecule sugar
Disaccharide
Either natural or manufactured sources and have almost no calories
Sugar substitutes
Insoluble, non seet forms of carbohydrates, exist in plants
Starches (Polysaccharide)
A complex CHO derived from plants, supplies roughage or bulkk to the diet
Fibers
Biological catalyst that speed up chemical reactions
Enzymes
Example of enzymes
Salivary amylase, pancreatic amylase, maltase, sucrase and lactase
What is the end product of Carbohydarte digestion?
Monosacccharid absorbed in small intestines
Major source of body energy
Carbohydrates
Continues to circulate in he blood and provide readily available source of energy
Glucose
Stored as either —— or —– in the cells, liver and skeletal muscles
Glycogen, fat
What happens when you have high or low blood sugar?
Reviewer process
Made up of primarily carbon, hydrogen, oxyge, nitrogen from amino acids and organi molecules
Proteins
—– of the bod solids are proteins
