Seven Principles of Clean Eating. We asked âclean eatingâ expert, Diane Welland, to break down the main principles of this buzz-worthy trend.
Dietary fibers can act by changing the nature of the contents of the gastrointestinal tract and by changing how other nutrients and chemicals are absorbed. Some types of soluble fiber absorb water to become a gelatinous, viscous substance which is fermented by bacteria in the digestive tract. Some types of insoluble fiber have bulking action and are not fermented. Lignin, a major dietary insoluble fiber source, may alter the rate and metabolism of soluble fibers.
Soluble fiber soaks up the moisture in food and slows digestion. This can help keep you regular if you make it part of your daily routine. Insoluble fiber adds bulk to your stool and relieves constipation faster, and has the added benefit of getting toxins out of your body quicker. Good sources of soluble fiber are: oranges, apples, carrots, oatmeal, and flax seed. Good sources of insoluble fiber are: nuts, seeds, fruit skins, and dark leafy vegetables.
