Researchers have found that plant foods with insoluble fiber, such as vegetables, fruits, nuts, and whole grains, contain unique bioactives, including beta-carotene, lycopene, quercetin, and lutein. Bioactives have been associated with health benefits, such as lower incidence of Type 2 diabetes and cardiovascular disease. Furthermore, researchers noted that plant byproducts of food productions (e.g., pells, hulls, pulp) could be used to fortify processed foods.
