ROLE OF DIETARY FIBRES IN DISEASES
• prevention of cardiovascular diseases by lowering blood
cholesterol
• Whole grainprotect against heart diseases
• Enhance the secretion of faecal steroids
• Soluble viscous fibres are hypocholestrolemic

• Soluble fibres such as pectins ,gums increase intestinal transit
time , delay gastric emptying , slow glucose absorption
• Including legumes and grains helps in lower blood glucose

DIABETES MELLITUS
• Fibre prevents constipation .
• Inulin present in onion inc. stool frequency
• Diverticulitis due to chronic constipation
• Piles (haemorrhoids) , irritable bowel syndrome
CONSTIPATION
• The fibre dilutes bile acids or binds to it thereby preventing
its role in mutation and cell proliferation .
• Fermentation of dietary fibre results in production of
butyrate which is antiineoplastic
• Consumption of FOS increase beneficial bifido bacteria .
• Lignin act as a free radical scavenger ,thus reducing the
risk of cancer
COLON CANCER
• High fibre diet promote weight loss
• Fibre increase satiety ,feeling of fullness
• Fibre reduces the absorption efficiency of small intestine .
WEIGHT CONTROL
• Temporary bouts of abdominal discomfort
