Fiber- we see this word everyday in newspapers, on the internet, and in food labels. Why do doctors and nutritionists recommend a daily intake of fiber, and how does it help in getting people to lose weight?
The Fiber in Foods
The fiber found in food is not the same type of rope fiber used to tow cars when they break down. Fiber comes in many forms, but what our bodies specifically need is Dietary Fiber. Essentially, dietary fiber is made up of nutrients that cannot be digested when they pass through our gastrointestinal enzymes and intestines. This plant compound is mainly a carbohydrate, made up of polysaccharides such as dextrins, chitins, beta-glucans, oligosaccharides, cellulose, pectins, inulin and waxes. You might also hear the terms “roughage” and “bulk” when dietary fiber is being mentioned in context, but these might mislead you in thinking that fiber is rough or bulky in appearance.
