Yes, washing hands, staying at home and practising social distancing is important, but what about your immunity? Your immune system plays an important role in keeping you protected from diseases and that’s why it’s essential to build your immunity.
Immunity cannot be strengthened overnight. While regular exercise is non-negotiable, consuming rich foods to boost immunity is even more crucial. From fruits and vegetables to immunity-boosting drinks, here are some superfoods that you must include in your diet.
Learn which nutrients these immunity-boosting fruits carry so that you can start your mornings with a refreshing boost to your body’s natural defences.
