Citrus fruits and vitamin C

When it comes to natural foods for a vibrant immune system, citrus fruits, and the vitamin C that they contain, should be at the top of your list. Vitamin C helps to increase the quantity of white blood cells – an intrinsic part of your body’s infection fighting capability.


Capsicums, or bell peppers, and red bell peppers in particular, actually contain more vitamin C than citrus fruits, pound for pound.

Broccoli – another of the natural foods for a vibrant immune system

Broccoli is another great food for boosting your immune system. It is packed with vitamins and minerals; in particular vitamins A, C and E. It also contains high levels of antioxidants. Cook it al dente to preserve its nutrient content. Better still, eat it raw.

Probiotic yogurt
