The investigators used a mouse model and found that eliminating pathogenic gastrointestinal bacteria reduced circulating inflammatory substances such as TMAO and improved the health of the animals blood vessels.   To apply this information for human benefit, they suggest that foods with beneficial bacteria such as yogurt, kefir, and kimchi as well as the consumption of fiber-rich foods will eliminate accumulations of harmful bacteria.  They also mention that olive oil, vinegar, and red wines are rich in dimethyl butanol, an a
