At the University of Toronto, studies examining specific dietary effects related to lowering blood cholesterol show that people adhere to a prescribed diet more faithfully and have reduced cholesterol levels when strawberries are included in daily meals. Such diets incorporate fruits, vegetables, soy products, prebiotic fiber (such as from oatmeal), plant sterols, and nuts.

It is often difficult to manage hyperlipidemia in FHC with standard dietary management. Specific fibers in appropriate amounts exert a pronounced hypolipidemic effect in man and animals. Pectin and Guar have been especially effective in lowering cholesterol in normal and hyperlipidemic patients.10-H However, not all fibers are effective in iowering lipids. No two sources of dietary fiber have the same effect on lipid metabolism. 2 Some dietary fibers, although effective as hypolipidemic agents, are not palatable or are difficult to incorporate into food because of increased viscosity or other chemical or taste properties.

Fibers and Fiber Sources. Fibers are present ia varyiag amounts ia food iagredients and are also added separately (see Dietary fiber). Some fibers, including beet pulp, apple pomace, citms pulp, wheat bran, com bran, and celluloses are added to improve droppiags (feces) form by providing a matrix that absorbs water. Some calorie-controUed foods iaclude fibers, such as peanut hulls, to provide gastroiatestinal bulk and reduce food iatake. Peanut hulls normally have a high level of aflatoxias. They must be assayed for aflatoxia and levels restricted to prevent food rejection and undesirable effects of mycotoxias.
