Fruits and vegetables are high an antioxidants which are really important for your body, so many some kind of antioxidant supplement. Instead of making fruits and veggies a chore maybe you could add them in by making a smoothie (frozen berries with yogurt) or even a soup (chicken stock and peas pureed together). If not you could always try V8 drinks too. Then maybe taking a multivitamin, with the a, b, c, d, e, magnesium's and calcium's etc.
