(i) The carbohydrates which are mainly used as food are :
Monosaccharides - glucose , fructose , galactose , etc :
. Disaccharides - sucrose , maltose , lactose , etc.
. Polysaccharides -starch
(ii) Indigestible carbohydrates which are not metabolized by our digestive enzymes are called diethary fibres. Chemically dietary fibre consists of cellulose. dextrins (resistant starch), lignin, chitins, pectins, etc. and some oligosaccharides. These are of two types - (a) insoluble dietary (or edible) fibre which does not dissolve in water and (b) soluble dietary (or edible) fibre which is soluble in water.
Their main sourcess are :
Insoulble dietary fibre : Wheat bran , most leafy vegatables and many other vegatables such as broccoli, cabbage and aculiflower and whole grain bread and cereals are the main sources of insoluble dietary fibre.
Soluble dietary : Legumes (peas, lentils soyabean and beans). oats , rye and barley, broccoli and carrots, potatoes, bananas, citrous fruits , apples berries and nuts, with almonds being the higest in or skin. Good examples are citrous fruits, apples and patatoes.
(iii) Geetika has expressed vales about fibre rich food for good health because of the following beefits.
. Insoluble fibre adds bulk to your stool and keeps it soft , removes all the toxins adhearing to the walls.
. Soluble fibre slows down uptake of dietary cholesterol thereby lowering the level of bad cholesterol , i.e., low density lipoprotein (LDL) in the blood. This can reduce your risk of coronary heary disease, heart attack and stroke . Soluble fibre also helps to maintain sugar level in the blood therby avoiding the risk of type 2 diabetes.
. Both soluble and insoluble fibres may also promote weight loss since high fibre diet is less energy dense and promotes a sense of fullness.
