• It make you feel full for longer period of time .
• Sources : oats, bran , lentils, vegetables, fruits etc.
5. INSOLUBLE FIBRES:

• It prevent constipation by adding bulk to stool( increase it’s weight and size)
.• It control problems related to bowl movement .
• Sources: Whole wheate bread, brown rice , in seeds etc.
7. FUNCTIONS
• It help in preventing constipation by increasing size and weight of stool.

• Constipation and diverticula
• Colon Cancer
• Weight Control
• Obesity
ROLE OF DIETARY FIBRES IN DISEASES
10. • prevention of cardiovascular diseases by lowering blood
cholesterol
• Whole grainprotect against heart diseases
• Enhance the secretion of faecal steroids
• Soluble viscous fibres are hypocholestrolemic
CORONARYHEART DISEASE
11. • Rich fibre diets lowers insulin requirement
• 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
• Fenugreek contains trigonelline reduces blood sugar level
DIABETES MELLITUS
12. • Fibre prevents constipation .
• Inulin present in onion inc. stool frequency
• Diverticulitis due to chronic constipation
• Piles (haemorrhoids) , irritable bowel syndrome
CONSTIPATION
13. • 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
14. • High fibre diet promote weight loss
• Fibre increase satiety ,feeling of fullness
• Fibre reduces the absorption efficiency of small intestine .
WEIGHT CONTROL
15. • Temporary bouts of abdominal discomfort
• Gas, flatulence

• We have discussed the importance , types of dietary fibre ,
sources of dietary fibre , their functions , roles in diseases
• Dieatary fibres are important for the healthy functioning of the
