Gastrointestinal Health Benefits of Sorghum Phenolics.

Sorghum is considered a promising food security crop and remarkable rich source of bioactive components including phenolic acids, flavonoids, and tannins. Sorghum phenolics exhibited numerous protective effects against multiple chronic diseases. However, there is no review of the effects of sorghum phenolics on gastrointestinal (GI) health. Specifically, recent studies have highly suggested that sorghum phenolics can maintain gastrointestinal homeostasis and enhance microbial diversity and richness. Furthermore, sorghum phenolics showed GI anticancer effects in both in vitro and in vivo studies against colorectal and esophageal cancers. Treatment of GI related human cancer cell lines stimulated apoptosis and suppressed proliferation. Sorghum intake and extracts treatments reduced intestinal oxidative stress and inflammatory mediators in human and in vivo studies. In addition, understanding the role and mechanisms underlying gastrointestinal health benefits of sorghum phenolics is crucial to determine treatment strategies of different GI diseases.
