Therefore, you should follow an anti-viral diet, paying particular attention to getting a good intake of vitamins D and E and the minerals selenium and calcium. Also eat organic wherever possible and have lots of soya (in tofu and soya milk), beans and lentils - although don' t overdo the soya, as this can encourage allergic reactions in some people. Supplement antioxidant nutrients and at least 3g of vitamin C a day. Also, avoid anything that weakens your immune system such as smoking, alcohol and fried foods. I recommend that you see a nutritional therapist who can help you find the perfect diet and supplement programme for you.
