Detailed explanation-1: -Factors which reduce the rate of absorption include the nature of the starch and sugars, and the presence of vegetable proteins, fats, viscous fibre, and antinutrients, including lectins and phytates.
Detailed explanation-2: -Amylase (made in the mouth and pancreas; breaks down complex carbohydrates) Lipase (made in the pancreas; breaks down fats)
Detailed explanation-3: -Fibre: Fibre helps to slow digestion of carbohydrate foods. High-fibre foods tend to have a lower GI than low fibre foods. High fibre foods such as whole grain breads, oats, beans, and lentils, have a lower GI than low fibre foods such as white bread and rice cereal.
Detailed explanation-4: -Carbohydrates are not chemically broken down in the stomach, but rather in the small intestine. Pancreatic amylase and the disaccharidases finish the chemical breakdown of digestible carbohydrates. The monosaccharides are absorbed into the bloodstream and delivered to the liver.
