Selenium, like Vitamin C, is a powerful antioxidant. It works alongside other antioxidants such as vitamins E and C and is essential for the immune system. Studies suggest that a selenium-rich diet can help to protect against skin cancer, sun damage and age spots which of course, we all want to avoid. One way to boost your intake is to eat Brazil nuts. Just four nuts will provide the recommended daily amount (RDA). That's it - just four!! Mix Brazil nuts with other seeds rich in vitamin E as a snack or salad sprinkle. Other good sources are fish, shellfish, eggs, wheatgerm, tomatoes and broccoli.
