nutrients (6)
Chemical substances that are found in food and necessary for good health.
Carbohydrates, fats, proteins, vitamins, minerals, water.
Essential nutrient
Nutrients found only in food
Carbohydrates
About 50% of diet. Provides energy. Protein sparing action. Normal fat metabolism.
Three types.
Monosaccharides
Simplest form of carbohydrates. No digestion required. Can be easily absorbed directly
into the blood stream from the small intestine they include glucose fructose and
galactose
Disaccharides
Double sugars. Hydrolysis to monosaccharides. Examples are sucrose maltose and
lactose
Lactose intolerance
Inability to digest lactose because if you lack of the enzyme lactase; causes abdominal
cramps and diarrhea
Polysaccharides
Complex carbohydrates containing combinations of monosaccharides. Examples
include starch dextrin cellulose and glycogen
Glycogen
Glucose that is stored in the liver and muscles. Approximately 1/2 day supply of energy
is stored as glycogen in the liver and muscles
