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. (ex: 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
fiber
Indigestible parts of plants; absorbs water in large intestine, helping to create soft stool
cellulose
Primary sources of dietary fiber
endosperm
The inner part of the kernel of grain; contains a carbohydrate. Contain starch protein and some B vitamins
germ
Smallest part of the grain and is a rich source of B vitamins vitamin E minerals and proteins
lipids and fat
Formed from glycerol Provides energy. 9 calories
hypercholesterolemia
Unusually high levels of cholesterol and blood; also known as high serum cholesterol. Common in clients with atherosclerosis
plaque
Fatty deposit on interior of artery walls. When plaque blocks the heart a heart attack occurs. When it blocks the brain a stroke occurs
function of stomach
temporary storage of food. mixing of food with gastric juices. regulation of a slow, controlled emptying of food into the intestine. sexretion of the factor for B12. destruction of most bacteria
