The digestibility of ether extract varies greatly from forages to grains and further to added fats consisting mainly of triglycerides. This variation has been attributed to two main factors, the presence of nonhydrolyzable substances in the ether extract, especially in leafy foods, and the dilution of endogenous fecal fat. A ...

Although there is strong evidence that the amount and type of fat in the diet can have dramatic effects on metabolism, the case for carbohydrate subtypes influencing metabolic parameters is emerging. By definition, resistant starch (RS) is any starch that is not digested in the small intestine but passes to ...

Animal studies have shown conclusively that feeding of resistant starch (RS) increases production of large bowel total short-chain fatty acids (SCFAs). However, fermentation products of RS may be affected considerably by other dietary ingredients. In rats fed a 20% high-amylose cornstarch (HAS) with casein as the sole protein source, greater ...
