Citrus fruits such as oranges, grapefruits, lemons and limes are rich in Vitamin C and contain antioxidants that prevent the break up of cells. Apples on the other hand contain the antioxidant Quercetin which reduces the risk of lung cancer. Strawberries are loaded with chemicals which help halt the growth of cervical and colon cancer.

2) Nuts

Nuts such as walnuts, almonds and Brazil nuts are rich in Vitamin E, a powerful antioxidant that helps boost the immune system especially in older generations. Hazelnuts and Pistachios are rich in Vitamin C which increases your white blood cell count and antibodies. Vitamin C also acts as an antioxidant that coats cell surfaces to prevent viruses or bacteria entering them.

3) Green vegetables   

Leafy vegetables like cabbage, broccoli and spinach are loaded with vitamins and antioxidants that boosts the functioning of your immune system. Other vegetables such as edamame contains phytosterols which reduces the cholesterol within the body, reducing your risk of a stroke or heart disease.

Oily fish such as Tuna and Salmon are rich in Omega 3 fats which increase the activity of your body’s white blood cells. An increase in white blood cell activity means your body is doing more to protect itself from infection or foreign bodies.

5) Garlic                                                                         

There are many health benefits associated with garlic from helping fight the common cold and reducing high blood pressure to fighting against various cancers such as colon, prostate and ovarian cancer. These benefits arise from antioxidants such as Selenium and Manganese as well as Vitamins C and B6. Eating garlic also aids fighting infections within the stomach.

6) Sweet potato

Sweet potatoes contain beta-carotene which turns into Vitamin A once you have ingested it. Vitamin A benefits your body in a variety of ways, one of which is helping to maintain healthy skin. Acting as your first line of defence, your skin helps prevent viruses and bacteria infecting your body.
