Dietary Fibres in Potato

Abstract

The dietary fibre (DF) is both starch and non-starch polysaccharide of our diet having a significant effect on gut physiology. It enhances the fermentation process, nutrifies gut microflora, enriches gut microbiome, and improves large bowel function. The recommended dose of DF in our diet is 20–35 g/day, which shows that how much important is the role of DF in our diet. The DF consumption not only lowers the effect of glycaemic response but also provides a protective role in large bowel cancer, diabetes, and coronary heart diseases. The DF can be classified majorly into two types, viz., water-soluble DF and water-insoluble DF. Water-soluble DF includes gum, pectin, and mucilage, whereas water-insoluble DF includes cellulose, hemicellulose, and lignin. Cooked potatoes are a good dietary source of carbohydrates which contains about 1.8% of total dry weight. Consumption of dietary fibre can confer benefits to heart health by influencing both lipid and glucose metabolism.
