Write a short note on Dietary Fibres?

The term ‘dietary fibres’ refers collectively to indigestible carbohydrates present in plant foods. The importance of these dietary fibres came into the picture when it was observed that the people having a diet rich in these fibres, had low incidence of coronary heart disease, irritable bowel syndrome, dental caries and gall bladder stones. The dietary fibres have the property of holding water. Their beneficial effects lie in preventing coronary heart disease and decreasing cholesterol level. The dietary fibres may have some adverse effects on nutrition by binding some trace metals like calcium, magnesium, phosphorus, zinc and others. It is suggested that an intake of 40 grams dietary fibres per day is desirable.
