Post Date: 2/4/12 9:19 am Well, fiber is technically a carbohydrate - it's a chain of polymerized (or linked) sugars. The thing with fiber is that they are carbs our body cannot break down - sugars or not. You probably know that humans can't digest cellulose from plants, right? We can't break that down. It's fiber - it passes through our digestive system. But pasta is also linked sugars, and we digest that quite fine - that's a complex carb.
Fiber keeps your regular and decreases your odds of having colon cancer.
Because fiber is a carbohydrate, and the way that nutritional law is written in the US, it's displayed under "carbohydrates" on the food label (because it is) but then consumers are left confused when they are wanting to minimize carbs or have a low-carb diet, but also told to keep fiber intake up.
