Effects of Moderate Consumption of a Probiotic-Fermented Sour Beer on the Inflammatory, Immunity, Lipid Profile, and Gut Microbiome of Healthy Men in a Participant-Blinded, Randomized-Controlled Within-Subject Crossover Study.

Probiotic sour beer (PRO) fermented with Lpc-37 is a novel beverage option, which may potentially offer health benefits. In this study, the effects of PRO are evaluated on the inflammatory, immunity, lipid profile, and gut microbiome of consumers in a 5-week, participant-blinded, randomized-controlled within-subject crossover study. Twenty-one healthy male participants consumed 330 mL of PRO and normal sour beer (CON) daily for 2 weeks each with a 1 week of washout.

Postprandial glycemic and lipidemic effects of black rice anthocyanin extract fortification in foods of varying macronutrient compositions and matrices.

Anthocyanin (ACN) fortification of commonly consumed foods is significant as a dietary strategy against the development of metabolic complications by delivering ACNs at high doses. However, its bioactivity and translated metabolic effects in the presence of varying food matrices and macro-constituents is particularly unclear. This end-to-end study investigates the metabolic effects of black rice ACN extract (BRAE) fortification-from in-vitro enzyme inhibitory activities and digestibility, to downstream in vivo impacts on GI, postprandial glycemia and lipidemia.

Impact of Starch-Rich Food Matrices on Black Rice Anthocyanin Accessibility and Carbohydrate Digestibility.

Anthocyanins reduce starch digestibility via carbohydrase-inhibitory pathways, but food matrix effects during digestion may also influence its enzymatic function. Understanding anthocyanin-food matrix interactions is significant as the efficiency of carbohydrase inhibition relies on anthocyanin accessibility during digestion. Therefore, we aimed to evaluate the influence of food matrices on black rice anthocyanin accessibility in relation to starch digestibility in common settings of anthocyanin consumption-its co-ingestion with food, and consumption of fortified food.

Effects of anthocyanins on bread microstructure, and their combined impact on starch digestibility.

Several studies have confirmed the reduction of starch digestibility with anthocyanins in food systems via mechanisms of enzyme inhibition. However, starch-polyphenol interactions may also contribute to this reduction, by modifying food microstructures and physicochemical properties of starch. The interactions among anthocyanins, starch digestibility, and food microstructures are significant to clarify the digestion processes of fortified food systems, but its interrelationship lacks clarity.
