Walnuts are one such super-food whose nutritional qualities are never-ending [and so are its beauty benefits. Know here]. According to a research done on mice for breast cancer prevention, it is believed that the anti-inflammatory qualities of this nut give your body a tumour-fighting potential, thus reducing the risks of cancer. You can either include these nuts in your meal by mixing them along with your breakfast cereal, or just have them as an evening snack.
