Document Summary
Carbohydrates (cho) = organic compounds made up of carbon, hydrogen, and oxygen. Glycolysis glucose is broken down into two 3-carbon compounds, ultimately into lactic acid to form atp. Complex cho (starches) 3 or more glucose molecules combined. Polysaccharide = 10 or more (short chains ~10-20 called glucose polymers or maltodextrin) Thousands of molecules = starches or fibre (plants) or glycogen (animals) Most plants contain both but composition varies (rice with high amylose is harder while rice with little amylose is sticky and soft) Dietary fibre = polysaccharides in plants that are resistant to digestive enzymes. Reduce coronary artery disease (cad) and colon cancer. Fibre = satiety = total energy intake. Major role in a loss of body fat during a diet. Fibre intake in north america is drastically less now than it was with our ancestors. Due to fibre being removed in the process of many food. Less processed foods = more fibre in diet.
