You love to eat at fast food outlets like MacDonalds, A & W and the likes, don't you? If you do, take note- you could be gobbling four of the top five cancer causing food: hot dogs, processed meat, doughnuts, and French fries. Hot dogs and processed meat contain sodium nitrate which are carcinogenic. Doughnuts and French fries which contain hydrogenated oils and are fried at high temperatures could just raise your chances of getting cancer. You would want to consider fasting on fast food!
