The battle against cancer can begin as early as you start your day.  A simple combination of three ingredients can lead to a reduced risk of developing cancer cells.  Aside from being chock full of anti-oxidants, oats are also believed to have a cleansing effect that drag food along, thereby lessening the chances of getting colon cancer.  When preparing your oatmeal, use soy milk, which is also rich in anti-oxidants, rather than dairy.  To round your breakfast out, replace your coffee with green tea.  A report from the Journal of the National Cancer Institute found that green tea possesses one of the most powerful anti-oxidants around.  Just one tip when buying green tea, be sure to check the ingredients before purchasing the box as some manufacturers add caffeine to the product.
