Red bell peppers
"Red bell peppers contain more vitamin C than oranges, and vitamin C encourages the production of the white blood cells that are responsible for defending the body against pathogens," says Kasper.
Vitamin A, which is helpful for supporting your immune system, can also be found in red bell peppers.
"Vitamin A is important in maintaining the natural mucus barriers located in the eyes, gut, and other parts of the body," says Kasper, "These barriers are designed to trap bacteria and are essential to optimal immunity."
Kasper also adds that it helps to choose red bell peppers specifically because they contain higher levels of vitamin C and A than green bell peppers.
"While vitamin D is often connected to bone health, emerging research out of Boston University suggests that it may also be vital to proper immune function," says Kasper.
