So in addition to polyphenols and fish oil, make sure you add prebiotic foods to your daily menu. Many of them also contain polyphenols, so your Akkermansia can get a double hit of goodness. For instance:Ottman, N. et al. Pili-like proteins of Akkermansia muciniphila modulate host immune responses and gut barrier function. PloS one 12, e0173004 (2017). Not all FODMAPs are health-promoting. Here is a list of some common foods and ingredients that are high in health-promoting FODMAPs that can promote the growth of A. muciniphila : 10 Rantala, A.
