2. Pickled Foods
Pickling is another form of processing that adds nitrates or nitrites, salt, and artificial coloring to food. In much the same way that too much alcohol can cause cancer in the parts of the body it touches directly, pickled foods are linked to cancer of the digestive track, especially the stomach and colon.
If you really love pickles, take the time to make them at home so that you can control the level of salt and avoid artificial pickling solutions.
