7. Leafy Greens
Leafy greens should be the cornerstone of any healthy diet, as they are exceptionally rich in vitamins, minerals, antioxidants, and enzymes, yet very low in calories, fat, sodium, and other toxins. Spinach, kale, and chard are all rich in known cancer-fighting antioxidants, including vitamin C and beta-carotene.
Add a handful of leafy greens to your lunches and dinners to boost your nutrient intake. To simplify your intake, try vegetable juices, which are very easy to digest and simple to prepare at home.
