Fiber foods (dietary fiber) is a component in plants that are not digested enzymatically into parts that can diserat in the digestive tract. Barbara Rolls, Phd, author of The Volumetrics Eating Plan, says the consumption of high-fiber diet is very good for lowering cholesterol, but also prevent constipation because fiber absorbs water when passing through the digestive tract so that the feces become soft tekstus. To be free from constipation, fiber consumption should be balanced with adequate water intake, because if not drinking, it will exacerbate fiber constipation or bowel disorders.
"Fiber not only reduces the density of food (the number of calories we / create), but also shorten the time lapse when the rest of the digestive tract through the system," said Rolls. This will reduce exposure to carcinogens intestinal wall. In addition, according to Joanne Slavin, PhD, an expert in the field of obesity from the University of Minnesota, fibers not only make your stomach feel more full, but also reduces digestive problems, including colon cancer.
Some studies even show that large amounts of fiber can help regulate blood sugar and insulin. This is why, people who often eat more fiber tend to be slimmer. Fiber is also known to show other benefits to health. High fiber intake (especially from cereals and products serelia) proved to slow the emergence of cholesterol plaque in women who suffer from heart disease. Adequate fiber consumption will also protect your heart by lowering bad cholesterol (LDL) without reducing good cholesterol (HDL). This is because high-fiber foods usually contain saturated fats and cholesterol low. The best sources of fiber are vegetables and fruits, and grains. The experts do not recommend the consumption of fiber supplements because of inappropriate consumption can cause intestinal obstruction and diarrhea.
