Foods containing vitamin A may be some of the best foods to boost immune system needs and health. Studies indicate that vitamin A can fight infection and inflammation in the body, and can even fight against some toxins, such as some types of food poisoning. Vitamin A-rich foods boost immune system properties by influencing and even helping to create beneficial cells in the body that fight certain diseases and conditions. So eating more vitamin A can boost immune system properties throughout the body.

Some common foods that provide vitamin A and boost the immune system include chicken, turkey, beef, carrots, sweet potatoes, pumpkin, spinach, collard greens and most all tomato products. There are also vitamin A supplements available if you need to boost immune system properties even more.
