When it comes to immune-supporting foods, there are tons and tons of options to choose from—after all, each fruit and veggie boasts its own impressive list of antioxidants and nutrients, which is why most experts recommend a diverse, vitamin-rich diet at large to really punch up the immune-supporting benefits.
