A study has proven that people who regularly consume yogurt possess optimal levels of inflammatory cytokines (infection-fighting cells) in blood.
Yogurt is also found to be beneficial for cholesterol reduction, stimulation of the immune system, and prevention of colorectal cancers.
6. Vitamin E
This nutrient stimulates natural killer cells of our body which target infective organisms and cancer cells and destroy them.
Vitamin E also enables the production of B-lymphocytes (a type of white blood cell) which produce antibodies.
Vitamin E can be found in raw spinach, sweet potatoes, nuts, grains, and seeds like almonds, walnuts, and peanuts.
This nutrient is a powerful antioxidant that enhances immunity and eradicates free radicals from the blood by increasing the number of white blood cells, natural killer cells, and helper T-cells.

Foods containing beta-carotene include carrots, sweet potatoes, pumpkins, spinach, kale, and red leaf lettuce.
