1. Kale
A single serving of kale has more calcium than six ounces of cow’s milk. Kale is the most bitter and nutrient-packed of all crucifers. Studies show kale is effective not only for helping to prevent cancer but also for slowing its growth. Store in the crisper drawer of your fridge and eat within a few days. You can lightly steam, sauté in extra-virgin olive oil, or make roasted kale chips!
2. Collard Greens
These beauties are full of vitamin C, and they’re a great source of vitamin K. They are yet another leafy green that may offer cancer killing benefits. When shopping for them in the store, look for dark green leaves that are crisp.
