It is not only about medicines, but a proper diet can also help you fight the infection of the coronavirus. This is because immunity, which relies heavily on diet, is essential to how the body deals with the attack of microbes, including the SARS-CoV-2 virus. Scientists know better and better what diet helps fight disease. The omega-3 fatty acids found in fatty marine fish may play an important role.
The search for drugs for COVID-19 is of course very important, but it is not the only way to help your body fight the coronavirus. After all, it is known that the daily diet and related nutrition of the body can significantly affect the susceptibility to infection and the course of various diseases. Scientists are looking for answers to questions about whether the presence of certain components in the diet might affect susceptibility to COVID-19, the course of this disease and the speed of recovery. And there are already the first positive reports about it – they refer to polyunsaturated fatty acids from the omega-3 family.
Fewer deaths among people with high omega-3 index
Omega-3 fatty acids are known for their positive effect on health, including the immunity of the human body. The latest empirical research on them, published in the journal Prostaglandins, Leukotrienes and Essential Fatty Acids, provides some really good information.
The study authors found fewer deaths in the group of COVID-19 patients with a higher percentage of omega-3 fatty acids (the omega-3 index), which indicates a higher concentration of EPA and DHA in the blood, compared to patients. With less omega-3 fatty acids. Although the research is preliminary and should be confirmed in subsequent experiments, the results obtained point to an important direction. Researchers believe this pilot study raises great hopes for the consumption of fish, seafood or fish oil supplements as sources of omega-3s in the prevention and treatment of COVID-19.
How do omega-3 fatty acids work in people with coronavirus?
COVID-19 varies in severity – from mild to very severe – it all depends on the patient’s organism. The underlying mechanism of the acute form of COVID-19 is caused by a highly potent inflammatory response, known as “Cytokine storm”. Silencing it by the patient’s immune system may ease the course of the disease and facilitate recovery.
Studies have shown that the effect of omega-3 acids led to a decrease in cytokine production, suppression of the cytokine storm and a reduction in acute inflammation. The first results from pilot clinical trials appear promising, although they require confirmation in further studies. However, they confirm what we already know: that omega-3 fatty acids are anti-inflammatory and have a beneficial effect on health, so they must be present in the diet on a daily basis.
What are the best sources of omega-3 fatty acids?
The best source of omega-3 fatty acids, such as DHA and EPA, in the diet are fatty sea fish, as well as seafood and algae. Although fish do not produce omega-3s themselves, they feed on marine phytoplankton rich in omega-3 fatty acids. The fish then store it in its muscles and liver. The best sources of omega-3 fatty acids are the following types of fish:
- rainbow trout
- salted fish
- shaft perch
According to the recommendations of nutritionists, fish and seafood should be eaten at least 1-2 times a week. The diet should include vegetable oils (such as olive oil and rapeseed oil), which are also a good source of omega-3 fatty acids.
