Red wine remodels gut microbiota (Part 1)

Moderate red wine (RW) consumption is reportedly cardioprotective, but RW effects on gut microbiota and plasma TMAO are not fully understood. We conducted a randomized, crossover, controlled trial involving 42 males, average 60 yr with documented coronary artery disease, comparing 3-week consumption of 250 mL of RW/ day, 5 days/ week, with an equal period of alcohol abstinence, given adequate washouts.
