  1. huda khan - soluble and insoluble dietary fiber in digestive tract says:

    Dietary fiber, also known as roughage or bulk, includes all parts of plant foods that your body can’t digest or absorb. Unlike other food components, such as fats, proteins or carbohydrates — which your body breaks down and absorbs — fiber isn’t digested by your body. Instead, it passes relatively intact through your stomach, small intestine, colon and out of your body.
    Fiber does way more than just keep you regular. The rough stuff can also help lower cholesterol, keep your blood sugar stable, make it easier to lose weight,, and even help keep you alive longer.

    To get all those benefits, there are two types of fiber that your body needs:
    soluble and insoluble. Both come from plants and are forms of carbohydrates. But unlike other carbs, fiber can’t be broken down and absorbed by your digestive system. Instead, as it moves through your body it slows digestion and makes your stools softer and easier to pass.

    Most foods contain both insoluble and soluble fiber but are usually richer in one type than the other. The easiest way to tell them apart: Soluble fiber absorbs water, turning into a gel-like mush (think of what happens when you add water to oatmeal) while insoluble fiber doesn’t (think of what happens when you add water to celery).
    Soluble Fiber:
    the kind that dissolves in water as it moves through your digestive tract – can help improve your health by slowing down the rate at which your intestines absorb cholesterol and glucose. By doing so, soluble fiber can help regulate your blood levels of these nutrients, which can be of use in managing diabetes or reducing your risk of cardiovascular disease. Of the recommended 25 to 30 grams of total dietary fiber you should get daily, roughly 25 percent – between 6 and 8 grams – should come from soluble fiber.
    Insoluble Fiber
    In contrast to soluble fiber, insoluble fiber doesn’t dissolve in water. It does, however, increase the bulkiness of waste products moving through your gastrointestinal tract, and, in doing so, it encourages regular bowel movements that are easy to pass. By reducing constipation and decreasing the likelihood of developing hemorrhoids and diverticular disease, insoluble fiber helps keep your digestive system in good working order. In addition, it can help you feel full for a longer period of time and may discourage you from overeating.
    The health benefits include:
    Normalizes bowel movements. Dietary fiber increases the weight and size of your stool and softens it. A bulky stool is easier to pass, decreasing your chance of constipation. If you have loose, watery stools, fiber may also help to solidify the stool because it absorbs water and adds bulk to stool.

    Helps maintain bowel health. A high-fiber diet may lower your risk of developing hemorrhoids and small pouches in your colon (diverticular disease). Some fiber is fermented in the colon. Researchers are looking at how this may play a role in preventing diseases of the colon.

    Lowers cholesterol levels. Soluble fiber found in beans, oats, flaxseed and oat bran may help lower total blood cholesterol levels by lowering low-density lipoprotein, or “bad,” cholesterol levels. Studies also have shown that fiber may have other heart-health benefits, such as reducing blood pressure and inflammation.
    Helps control blood sugar levels. In people with diabetes, fiber — particularly soluble fiber — can slow the absorption of sugar and help improve blood sugar levels. A healthy diet that includes insoluble fiber may also reduce the risk of developing type 2 diabetes.

    Aids in achieving healthy weight. High-fiber foods generally require more chewing time, which gives your body time to register when you’re no longer hungry, so you’re less likely to overeat. Also, a high-fiber diet tends to make a meal feel larger and linger longer, so you stay full for a greater amount of time. And high-fiber diets also tend to be less “energy dense,” which means they have fewer calories for the same volume of food.

    Another benefit attributed to dietary fiber is prevention of colorectal cancer. However, the evidence that fiber reduces colorectal cancer is mixed.
    How much fiber do you need each day? The Institute of Medicine, which provides science-based advice on matters of medicine and health, gives the following daily recommendations for adults:
    Age 50 or younger Age 51 or older
    Men 38 grams 30 grams
    Women 25 grams 21 grams
