Fats / lipids (oils, butter, margarine, nuts, seeds, avocados and olives, meat and seafood)

These 2 essential fatty acids are the starting point for other important omega-acids (e.g. DHA, EPA)

Soluble fiber -- which dissolves in water -- is readily fermented in the colon into gases and physiologically active by-products, such as short-chain fatty acids produced in the colon by gut bacteria; it is viscous, may be called prebiotic fiber, and delays gastric emptying which, in humans, can result in an extended feeling of fullness.
Insoluble fiber -- which does not dissolve in water -- is inert to digestive enzymes in the upper gastrointestinal tract and provides bulking.Some forms of insoluble fiber, such as resistant starches, can be fermented in the colon.Bulking fibers absorb water as they move through the digestive system, easing defecation.
