Probiotics May Reduce Severity of Heart Attacks

Happy Chinese New Year!
According to a new study in rats, the bacteria that reside in our digestive tract may have an effect on the severity and risk of heart attack.

The study involved three groups of rats. The first group was fed a standard diet. The second group was treated orally with an antibiotic in their drinking water. The third group was fed a commercially available probiotic supplement that contains Lactobacillus plantarum 299v – a probiotic bacterial strain that suppresses the production of leptin (a protein hormone that plays a key role in appetite and metabolism).

The group fed the probiotic showed a reduction in circulating leptin levels (by 41%), smaller myocardial infarcts (29% reduction in heart damage), and improved mechanical function (23%).
