Dietary Fibre Protects Us From Diabetes, Heart Disease, Strokes And Colon Cancer!

Dietary Fibre, commonly known as roughage, is an essential component of our food. It includes all the parts of plant foods that we cannot digest or absorb. It passes through our digestive tract and is eliminated from our body more or less unchanged. The word fibre is really a bit of a misnomer in the sense that not all the plant parts that are included in this food group are fibrous.

Most of us know fibre as the element of our food that prevents constipation. But there are other vital health benefits of fibre for us.

Chemically, dietary fibre consists of non-starch polysaccharides such as arabinoxilans, cellulose, and many other plant components such as resistant starch, resistant dextrins, inulin, lignin, waxes, chitins, pectins, beta-glucans, and oligosaccharides.

Fruits, vegetables, whole grain cereals, pulses and legumes, nuts and seeds are the major sources of fibre in our food. Thus our normal Indian food, with major emphasis on vegetarian food, is naturally rich in dietary fibre.

It is the high fat, high protein egg and meat based Western food that is deficient in fibre.

Dietary fibre is broadly classified as soluble and insoluble fibre.

Soluble fibre dissolves in water, forming a gel like substance that absorbs cholesterol and sugars and clears them out of our bowels, reducing their absorption in our blood stream, thus helping lower blood cholesterol, especially LDL, the bad cholesterol and sugar. Thus it helps lower the risk of diabetes, heart disease and strokes.

Soluble fibre sources are oats, pulses and legumes, apples, citrus fruits, carrots, barley and psyllium (isabgol).

Insoluble fibre obviously does not dissolve in water. It absorbs water, adds bulk, softens stools and speeds up it’s transit through the bowels and relieves constipation. It regulates bowel movement, promotes growth of useful bacteria in the bowels, regulates the pH in the bowels, helps eliminate toxins from the bowels and helps prevent colitis, haemorrhoids and colon cancer.

Insoluble fibre sources are all types of fruits and vegetables, especially leafy vegetables, potatoes, beans, nuts, whole grain cereals and bran.

In fact most plant foods have both kind of fibre in varying amounts, a little more insoluble than soluble fibre.

Most fibre rich foods are also rich in vitamins and minerals and low in fats and calories. Thus a fibre rich diet also helps us get and stay slim and healthy.

If you eat balanced nutrition, including a combination of whole grain cereals, pulses and legumes and fresh vegetables and fruits, you don’t have to worry about getting adequate fibre. To derive the full benefits of fibre, it is essential to drink ample water.

Too much fibre can cause gas formation and colic in abdomen. It can also cause constipation if you don’t drink enough water. So don’t overdue fibre and make sure you drink ample water.
