Vitamin A: Vitamin A is essential for maintaining healthy mucous membranes, which act as a barrier against pathogens.
Antioxidants: Antioxidants, such as anthocyanins, flavonoids, and carotenoids, protect your cells from damage caused by free radicals.

Research and Studies
Numerous studies have highlighted the benefits of fruits for immune health. Here are a few examples:
