Refined sugars, oils, dairy products and alcohol contain no fiber and comprise 48% of the energy in the average U.S. diet. Getting enough fiber is important for overall health and disease prevention. Collagen fiber is made from fibrous protein subunits linked together to form a long and straight fiber.Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. Resistant starch has numerous powerful health benefits. Connective tissue is classified into two subtypes which are soft and specialized connective tissue.
