HLTH 230 Lecture Notes - Lecture 3: Fermented Milk Products, Dietary Fiber, Cereal
Document Summary
Supplies energy to the brain and muscles. We do not get most glucose by eating it directly. Carbohydrates: composed of carbon, hydrogen, oxygen, arranged in monosaccharides and multiples of monosaccharides, have ratio of one carbon molecule to one water molecule. Occurs in small amounts in fermented milk products (yogurt, aged cheese: disaccharides. Form of energy storage in animal bodies. Long branched chains of glucose: branch structure allows for rapid hydrolysis. Stored in muscle and liver: not significant source of carbohydrate from food. Also built from glucose units: branched chains. Grains are rich in starch: amylopectin bigger - Resistant starches: escape absorption and digestion in the small intestine, due to the foods physical properties, can help support a healthy colon. Provide structure in stems, trunks, roots, leaves. Contains a variety of monosaccharides and others in fibre. Dietary fibre: nonstarch polysaccharides in plant foots, not digested by human digestive enzymes, can be digested by bacteria, cannot be broken down.
