Do people need to avoid eating processed, plasticized, and canned foods and beverages? It has been found that these types of foods and beverages contain chemicals that are endocrine/hormone disrupters and carcinogens, causing several adverse medical conditions and diseases. Do these chemicals really affect people’s normal cell functioning? For example, why would a child’s cells be affected by consuming bisphenols from soda cans, nitrates and nitrites from colored processed foods, and phthalates from plastic-packaged foods (among many other examples)? People may not want this for their children and for themselves, but how come we are still being polluted by food products we buy in the supermarket? What is the truth behind eating packaged processed foods and liquids?
