Researchers evaluated plasma levels of DHA, an essential polyunsaturated omega-3 fatty acid, docosahexaenoic acid.
After adjusting the models for various factors that may have influenced the results, the team found that those with the highest omega-3 index were 21% less likely to test positive for COVID than those with the lowest levels. Additionally, patients with the highest omega-3 index had 26% less need for hospitalization than those with the lowest.
