Gut Issues Essay, Research Paper


We share many experiences with the kings of old:


pastries, for instance, and home entertainment and


vacation trips to far-off lands. Ancient-day


common folk knew nothing of such things. Then


again, they weren’t constipated… We are. Not all


of us, of course. But enough Canadians so that


some doctors call our a constipated society. And


even if you’re not constipated, your present day


diet may be leading you to more serious


complaints like disorders of the large intestine or


colon. These, too, were afflictions of of the upper


classes of old. Why? Because in general the rich


refined their food, along with their lives, and so


stripped it of an odd but essential ingredient called


dietary fibre. Like its fellow carbohydrates, the


various types of dietary fibre are the product of


sunlight, water and carbon dioxide combining in


green plants. Most form part of plant cell walls.


But unlike the other carbohydrates, fibres do not


break down into sugars in the human digestive


system and then course through the blood stream


fueling muscles and nerves. Rather, when eaten


they tumble intact through the stomach and small


intestine and end up in the colon where billions of


bacterial feed on them – in turn producing intestinal


gas. No wonder, then, that dietary fibre has been


unwelcome in many of history’s nicer


neighborhoods. Even 20th century doctors


reasoned that since the bulky material provided


not a single nutrient, it would only strain already


troubled guts. Accordingly, they recommended


low-fibre diets for patients suffering from


hemorrhoids and other colon disorders often


fou

nd in the West. But then, about 15 years ago,


the prescription was reversed as researchers


found that poor Africans, who eats lots of fibre,


rarely suffer from such complaints. Fibre, the


researchers learned, actually eases the bowel’s


burden by mixing with water and other food


residues to create large, Soon, nutritionists came


to see the low-fibre diet of most North Americans


as a culprit in the onset of disorders ranging from


tooth decay to heart attacks. Increasing the


consumption of certain kinds of fibre, they found,


could slow the body’s absorption of sugars to


which diabetics are sensitive, and of cholesterol,


which may lead to heart disease. Furthermore,


fibres fight obesity. They’re filling, especially the


pectins in citrus fruit and the gums in some beans.


And they’re mainly indigestible. So dieters eating


lots of fibre are likely to eat less of other, more


fattening foodstuffs. As for why populations on


high-fibre diets seem to experience fewer colon


cancers, no one knows for sure. In any case, there


is no doubt that fibre is nature’s laxative, the


dietary key to regularity. Nutritionists therefore


advise you to stay away from foods containing


processed and refined ingredients such as


bleached flour and white sugar. Remember that


meats contain little fibre and that overcooked


vegetables and fried foods have lost much of


theirs. Nevertheless, fibre supplements are usually


unnecessary. Merely ensure that your diet is full of


fresh fruits and vegetables – and some of the most


fibrous foods such as bran cereals, whole wheat


breads, peas, beans and lentils – and you, too, can


eat like an old-time pauper.
