30. Extra Fruit, vegetables, kidney beans, baked beans, oats, barley Dissolves in water-form gel that expands foods undergoing digestion, allowing it to pass through the digestive system more easily and prevent constipation Reduces absorption

31. Roughage passes out the alimentary canal in the faeces, WITHOUT being absorbed and assimilated into the body

32. Why we still need to consume it?

33. It has a high water holding capacity It provides bulk to intestinal contents, especially in the large intestine. This aid peristalsiswhich allows gut muscles to grip food & move it along quickly through the digestive tract. Roughage /Dietary Fibres 肠癌

34. This prevents the built-up of toxic substances in the rectum. Toxic in rectum-leads to bowel cancer. Roughage /Dietary Fibres 肠癌

35. Stimulate peristalsis Prevent constipation Weight-control throuh the “stomach-full” feeling Absorbing and eliminating toxic substances Prevent cancer of colon and rectum Roughage /Dietary Fibres

36. Deficiencyof Roughage constipation & Other disorder of large intestine Hemorrhoids Bowel cancer Colon cancer
