Bran contains two types of dietary fibre, soluble and insoluble. It is the insoluble fibre that helps the body by providing bulky fibre and promoting bowel regularity. Wheat bran contains around 33.3% insoluble fibre, rice bran 23% and oat bran around 5.5%.
If regularity is the problem, then it may be that the diet is lacking in insoluble fibre. If this is the case, then including 60 grams of rice or wheat bran will help. Drink 6 to 8 glasses of water daily as water moves food through the digestive tract.
The soluble fibre found in bran is as important as the insoluble fibre. Soluble fibre can help reduce the. risk of certain types of heart disease by reducing blood cholesterol levels and improving the HDL:LDL ratio. HDL, or high density lipoproteins are responsible for carrying excess cholesterol from the blood stream back to the liver. The liver uses cholesterol to manufacture bile salts which are needed to emulsify fats in the intestine for absorption. LDL, or low density lipoprotein, transports cholesterol to different parts of the body for use by the cells. However, excess LDLs are deposited on the artery walls if not used. This can lead to a hardening and narrowing of these blood vessels resulting in cardiovascular” disease.
