Food antioxidants can prevent or/and delay free radical formation which is responsible for oxidative stress. Nowadays, natural remedy becomes the highest concern in many countries, as well as discouraging the intake of synthetic counterparts to avoid the burden of side effects on human health. Regular intake of dietary antioxidants could help to improve the fitness of the body, and subsequently make the body more competitive in its fight against diseases through enhanced immune response. The present review thus summarised recent knowledge on the dietary source of antioxidants, and also mechanism of action and functionalities on human health benefits. Due to the proven ability to restore mitochondrial function and cellular redox balance, food antioxidants also have great potential as natural therapies against COVID-19. However, the numbers of trials are still limited. There must be more tests with the hope that these compounds will mitigate the COVID-19 and similar outbreaks in the future.
