The onslaught of global COVID-19 pandemic has made one thing clear: Immunity is the most crucial weapon against this contagious condition. That is why scientists all over the world are racing against time to find a vaccine against the COVID-19 infection. In fact, experts and governments are also turning to Ayurveda to rev up the overall immune system in order to reduce your risk of this condition. While vaccines and certain schools of medicine can improve our body’s defence mechanism, there are certain foods that will help us do the same.

What exactly are fermented foods?
A food becomes fermented when bacteria, yeast or other living microorganisms break down its sugar and turn it into alcohol and acid. Yogurt, kefir, sauerkraut and some kinds of cheese are examples of fermented foods which are loaded with lactic acid bacteria and other living microorganisms. Research suggests that they benefit our health in more ways than one. Improving our digestive system, boosting weight loss and revving up the immune mechanism are some of the health perks these bacteria and microorganisms are associated with.

How do fermented foods boost immunity?
According to the findings of researchers at the University of Leipzig in Germany, lactic acid bacteria found in fermented foods generate an acid in the digestive tract. This acid binds well with the proteins found in immune cells, known as HCA3 receptors. This whole process, researchers observe, boost the capacity of our immune system. Scientific evidences also suggest that some fermented foods reduce your risk of catching an infection, thanks to the high volume of vitamin C they have. Sauerkraut and kimchi are such examples.

Kimchi: This a close cousin of sauerkraut. Made from cabbage again, kimchi is a more spicy version. You can use it as a topping on your tacos and burgers.
Kefir: This is a milk-based drink tasting more like yogurt. It is the result of healthy bacteria breaking down its lactose. It is loaded with an essential micronutrient: Calcium. You can have it in your smoothies.

Yogurt: This is made from fermented milk. The probiotics in yogurt not only increase the count healthy bacteria in your gut flora but also help in digestion.
