Document Summary

Milk and alternatives (ex. milk, yogurt, but not cheese) Essential cho- main source of energy for brain and nerves. Part of lactose (milk sugar); freed during digestion. Sucrose= glucose + fructose (table sugar- beat or cane) Lactose= glucose + galactose (sugar in milk- poorly digested by some people) Maltose= glucose + glucose (malt sugar- in germinating seeds- important in brewing) Poor tolerance- pancreatic juices aren"t producing enough lactase lactose free milk- add digestive enzymes to milk which split lactose molecules into its monosaccharides. Probiotic bacteria in colon can digest fibre into short chains of fatty acids. Storage form of cho in liver and humans in humans and animals. Critical energy source for the brain and nerves. Choose nutrient dense (ex. fruits and milk) vs. empty-calorie. Canada"s food guide (cfg): whole grains, fruit, starchy vegetables, milk. Dri: minimum 130g/day (glucose for brain and nerves); 45-65% of total calories from cho. World health organization: 55-75% of total calories from cho.
