Scientists discovered a beneficial bacteria called Enterococcus faecalis HY0110 from bluefin tuna that could help protect gut health and fight harmful pathogens better than current probiotics. This marine bacteria produces important compounds like acetic acid that kill disease-causing bacteria, reduce inflammation in inflammatory bowel disease, and even slows cancer cell growth. When fermented with cockroach powder, it creates powerful health-boosting compounds that could make functional foods more effective for managing digestive diseases and supporting overall wellness.
