Give Me Fiber
Thursday, May 6th, 2010Have you eaten your fiber today? If not, you may be courting some chronic diseases you might just as well avoid.
In many nations where food staples are whole grains, vegetables, and possibly a variety of fruits, writings about fiber would hardly be worth the effort. But in some where the bran is removed from wheat and rice, where meat, fish and fowl push out those fiber-rich foods, we find the linkage between fiberless foods and diverticulosis of the colon, diabetes, and cancer (especially cancer of the colon). And, yes, like it or not, heart disease, the kind that comes with high cholesterol and clogged coronary arteries.
Would you like to add more fiber to your daily dietary fare? In the main, fiber comes in several packages. There’s the kind that we find in grains (like oats, corn, barley, and rice) and legumes (like beans of all kinds, peas, and garbanzos). We find the same kind in the fleshy portions of pears and apples, in carrots and prunes. These cut cholesterol levels and reduce heart disease.
Consider the kind of fiber that doesn’t dissolve in water. Cellulose is one of these. Fiber forms bulk, so the stool is larger and softer and passes through the digestive tract faster. That means less constipation and straining. Even more important, a short stool-transit time decreases the likelihood of cancer, especially colon cancer.
Would you like some water-insoluble fiber in your diet today? Be sure to include foods like leafy vegetables, and don’t forget the celery. Unpeeled apples and pears are great, as are strawberries, and gain, grains-like oats, barley, corn, and rice. And don’t forget wheat. Of course, it should be whole wheat.
Most of us get only about a third of an ounce of fiber daily. Doubling that would be great.
A half cup of all-bran cereal contains about a third of an ounce-an apple, a pear, or a baked potato, about an eighth of an ounce. A cup of kidney beans contains a third of an ounce.
Is it possible to take too much fiber? Yes, especially if the fiber is taken as a supplement or a concentrate. Some experts believe that too much fiber can interrupt, or at least decrease, the absorption of certain trace minerals, including iron, zinc, and calcium.
Too much fiber taken all at once can cause abdominal distention and excessive gas. So if you decide to improve on your fiber intake, use good sense and come up to par, perhaps over a period of several days rather than all at once.
