Fatty Fish
Oily fish contains omega-3 polyunsaturated fatty acids, which have been shown to reduce inflammation and may reduce the risk of heart disease, cancer, and arthritis. Both white and oily fish are high in lean protein. According to a research review published in Infection & Chemotherapy in December 2020, omega-3 fatty acid sources such as fish (such as salmon, cod, and sardines, according to the Mayo Clinic) may help lower the inflammation associated with COVID-19.
Previous research has shown that omega-3 fatty acids are incorporated throughout the body into a specific layer of your cell membranes, according to those researchers. They note that this process can help reduce inflammation, which may have an antiviral effect. Nonetheless, more research on omega-3s and COVID-19 is required.
