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.

7. Beta-carotene

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

8. Omega 3 Fatty Acids
