Prebiotic nut compounds and human microbiota

Crit Rev Food Sci Nutr. 2017 Sep 22;57(14):3154-3163. doi: 10.1080/10408398.2015.1096763.


Nut consumption is clearly related to human health outcomes. Its beneficial effects have been mainly attributed to nut fatty acid profiles and content of vegetable protein, fiber, vitamins, minerals, phytosterols and phenolics. However, in this review we focus on the prebiotics properties in humans of the non-bioaccessible material of nuts (polymerized polyphenols and polysaccharides), which provides substrates for the human gut microbiota and on the formation of new bioactive metabolites and the absorption of that may partly explain the health benefits of nut consumption.

Keywords: Nuts; butyrate; fiber; polyphenols; polysaccharides; urolithins; valerolactones.
