Fatigue facilitates the development of viruses such as the coronavirus. To boost your energy, focus on iron-rich foods such as blood sausage, offal, eggs, red meat and fish.
Concerning zinc, it has an antioxidant power which allows to reinforce the immune system. It helps the body to fight against infections by producing anti-microbe molecules. To reduce the risk of coronavirus, eat regularly foods that contain zinc. These foods include seafood, organ meats and beef.
