Consume 35 portions of fruits and veggies a week. Make sure cauliflower, broccoli and kale are at least three of those and spinach, collards and other leafy greens are another four to six, while seven servings are citrus fruits. Stock up on fatty fish such as mackerel, sardines and trout. Eat at least one serving every five days. Herbs are also rich in antioxidant properties. Add fresh sage, rosemary, parsley and basil to reap the protective benefits of the good green stuff. Another steep measure is to consume green and black tea on a regular basis. The antioxidants found in this drink stop the proteins that cause skin cancer to develop. Also, be sure to enjoy a glass of red, red wine. Studies show the catechins and resveratrol found in wine protect against cancer and growth of human cancer cells.
