Most of the benefits from soluble corn fiber that couldn’t be found in IMO fiber emerge from the particular short-chain fatty acids that soluble corn fiber turns into while it moves into the large intestine1. The most abundant and important SCFAs are acetate, propionate, and butyrate, which all have considerable importance for human health
• Human studies show butyrate has anti-inflammatory effects, both in the gut4 and on wider-reaching systemic inflammations5, as well as benefits to the cardiovascular system6.
• Further studies on animals show a reduction in body fat percentage7, improved insulin sensitivity8, improved immune responses9, greater oxidization of fats10, and an increased sense of satiety11.
• Butyrate is also directly linked to H-DAC suppression in humans, which is one of the factors thought to be responsible for the anti-cancer effects12 of caloric restriction.
• Blood glucose and insulin responses to corn-based dietary fibers are excellent and extraordinarily predictable13.
