Going beyond precautions and vaccinations, doctors and the World Health Organization (WHO) have advised that proper nutrition and hydration would be key in fighting the second wave of Covid-19. It requires a throwback on some ancient wisdom.
About 2,500 years ago, Hippocrates, the Father of Medicine, hit the nail right on the head when he said: "Let food be thy medicine and medicine be thy food."
In January, the CSIR-Centre for Cellular and Molecular Biology (CCMB), Hyderabad had entered into an agreement with Arya Vaidya Sala (AVS), Kottakkal to check for the efficacy of ayurvedic formulations in the fight against coronavirus. AVS will provide standardised ayurveda formulations, and the CCMB will test them on the lab-grown coronavirus strains in cell culture system, and check for their anti-viral efficacy.
According to WHO, people who eat a well-balanced diet tend to be healthier with stronger immune systems and lower risk of chronic illnesses and infectious diseases. It goes on to add that one should eat a variety of fresh and unprocessed foods every day to get the vitamins, minerals, dietary fibre, protein and antioxidants for body needs.
A balanced diet helps in building a strong immune system that can help withstand any assault by the virus. In the current situation, it is necessary to be aware of the specific types of food that can improve our immune system in order to combat Covid-19.
