Document Summary
Carbon, oxygen, hydrogen: arranged as monosaccharaides (disaccharides, polysaccharides) Dri for carbohydrates: ai for infants ear, rda for children, adults, pregnancy and lactation. Ear men & women 19+, 100 g/day. Rda- men& women 19+, 130 g/day. Provided for minimum amount of glucose used by the brain. Average intake is 200- 330 g/day for men, 180- 230 g/day for women. Amdr 45- 65% of total daily energy intake, emphasis is on grains, fruits and veggies. They will make you fat 2. They are bad for you: they will give you diabetes. Complex carbohydrates polysaccharides> 10 monosaccharide"s linked together. Oligosaccharides: 2- 10 monosaccharaides linked together. Monosaccharaides 6 carbon sugars, glucose, fructose, galactose. Structural differences account for differences in sweetness. Blood glucose level is regulated by hormonal secretions (insulin and glucagon) Blood glucose falls as glucose is taken up into the cells. Seldom free in nature: usually bound with glucose in lactose (milk sugar, only monosaccharide obtained primarily from animal sources.
