According to an article in The Guardian, patients who have died or been admitted to intensive care with Covid-19 have been found to be deficient in a vitamin found in spinach, eggs, and hard and blue cheeses, raising hopes that dietary change might be one part of the answer to combating the disease.
A Dutch researcher Dr. Rob Janssen Says vitamin K could be the key nutrient and encourages a healthy intake of vitamin K, except to those on blood-thinning medications such as warfarin.
According to Dr. Janssen, there are vitamin K1 and K2. K1 is in spinach, broccoli, green vegetables, blueberries, all types of fruit and vegetables. K2 is in Dutch cheese and French cheese.
He also says that natto is particularly high in the second type of vitamin K and there may be cause for further studies into its health benefits.
“I have worked with a Japanese scientist in London and she said it was remarkable that in the regions in Japan where they eat a lot of natto, there is not a single person to die of Covid-19; so that is something to dive into, I would say,” he added.
It seems to be easy to absorb K1 from plant-based sources, but it is harder for vegetarians or vegans to get K2 if cheese is the main source.
That makes natto to be your savior.
