2022 article

Phenolic-rich beverages reduce bacterial TMA formation in an ex vivo-in vitro colonic fermentation model

Iglesias-Carres, L., Racine, K. C., & Neilson, A. P. (2022, July 11). FOOD & FUNCTION.

By: L. Iglesias-Carres  n, K. Racine n & A. Neilson n 

MeSH headings : Atherosclerosis / metabolism; Bacteria / metabolism; Beverages; Chlorogenic Acid; Choline / metabolism; Coffee; Fermentation; Humans; Methylamines / metabolism
TL;DR: Regular cocoa and coffee consumption could be a nutritional strategy able to reduce TMAO levels, and fractionating digested bioactive beverages determined that those fractions rich in chlorogenic acid were the most bioactive. (via Semantic Scholar)

Flavanol Polymerization Is a Superior Predictor of alpha-Glucosidase Inhibitory Activity Compared to Flavanol or Total Polyphenol Concentrations in Cocoas Prepared by Variations in Controlled Fermentation and Roasting of the Same Raw Cocoa Beans

ANTIOXIDANTS, 8(12).

By: K. Racine*, B. Wiersema *, L. Griffin n, L. Essenmacher*, A. Lee *, H. Hopfer *, J. Lambert *, A. Stewart *, A. Neilson n
