Some food sources of dietary fiber are wheat, rye, oats, beans, peas are some of the main foods that provide good fiber that can benefit people. Fruits and vegetables are better sources of fiber, but people would have to eat more of these foods in order to equal the fiber contributions of beans or cereal grains.
Soluble fiber helps increase the diet quality and decrease the rick of cardiovascular disease while insoluble fiber helps decrease cardiovascular risks and slow the progression of cardiovascular disease in high-rick individuals. Insoluble fiber promotes more calories that are absorbed by the body by slowing gastric-emptying.
The fiber recommendations for children versus adults is that children older than 2 years should adopt a diet that reduces the total and saturated fat intake to 30% and 10 % of total calories. When a childs calorie intake approach the adult range then 25 total grams of fiber should be tolerated. Children have to have a certain amount of fiber until they reach the adult range then they will be able to consume more fiber that will benefit them rather than hurt them.
I did not think that fiber was really important in a diet comparing to red meat or just plain eating and working out. I know now that many foods people eat must be taken in certain portions or diseases could take effect in the body. Preventing diseases with simple things as what we eat should be really simple as long as there are guidelines.
