Key Findings: Human gut bacteria can be either beneficial or harmful. Prebiotics are compounds in foods that promote the growth of beneficial bacteria. Some of the prebiotic compounds of nuts (including peanuts) include proanthocyanidins, polyphenols and fiber. Studies have identified that some of these prebiotic compounds may stimulate hormones in the gut while increasing the concentration of bifidobacterium and lactobacillus (good bacteria).
