why do we need fiber in our diets?

Answer 1

We need fiber to get rid of bad cholesterol. To soften stool, to absorb excess water, there are many reasons why we need fiber in our body.

Answer 2

Fiber is crucial in the diet, because of it's ability to keep food moving through the intestines. Fiber also provides a sensation of feeling full and is excellent for lowering cholesterol. Fiber doesn't have to taste bad either. Strawberries are a favorite of nearly everyone and full of fiber.

Answer 3

Fiber is commonly eaten for weight control as well as for the daily diet. The gel-like substance that soluble fibers form when they dissolve in water causes things to swell and move slower in the intestines. This increase in time that foods stay in the intestines has been shown to reduce hunger feelings and overall food intake. It has also been shown to decrease the number of calories that are actually absorbed from the ingested food. One study showed an increase in the number of calories that were excreted in the stools when high-fiber psyllium gum-based crackers were given in comparison to low-fiber crackers. Whenever fewer calories are taken in, or more are excreted, weight loss will generally occur. If we were to sit down and have a "heart to heart," I would tell you that one of the best things that you could do on your own to protect your heart is to follow a high-fiber diet. A high-fiber diet may be just what the doctor ordered to get your blood sugars under control. Keeping our blood sugars stable is a goal that we would all benefit from. If you don't have type 2 diabetes, this could be the way to prevent it. If you do have it, this could be the way to keep it under control. The best time to address type 2 diabetes is before it has developed. Research has shown that high-fiber diets can help prevent this form of diabetes. The most recent study on done on overweight and obese men and women without diabetes showed reductions in blood sugar and insulin with the use of a high soluble fiber supplement. Fiber helps by decreasing transit time, increasing stool weight, and decreasing pressure within the colon. The same has been found for irritable bowel syndrome (IBS). The current guidelines for the treatment of IBS include following a high fiber diet. The bulk that fiber provides is thought to help prevent the painful spasms often associated with IBS and aid in comfortable regularity. There is still a great deal of debate about the role of fiber in preventing colon cancer. The studies that look for connections with people's diets and their health have seen a trend in low-fiber diets and people with colon cancer.Fiber may just be the way to go when constipation is the problem. Although what constitutes constipation is not well established, diets that increase the number of bowel movements per day, improve the ease with which a stool is passed, or increase stool bulk are considered beneficial. Both soluble and insoluble fibers are necessary for regular bowel movements. Oftentimes, people use over-the-counter supplements to assist with regularity. Unfortunately, these supplements only provide soluble fiber. Studies support the benefits of the combination of soluble and insoluble fiber in alleviating constipation, but only with the consumption of an adequate fluid intake. High amounts of fiber, without fluids, can aggravate, rather then alleviate constipation. The way to go is to eat foods high in both soluble and insoluble fibers and drink lots of water to flush it down.It's not that hard to get fiber in the diet. Most of the foods we eat, naturally have fiber!
