You probably consume processed foods regularly. In fact, 70 percent of all food consumed by Americans is actually processed. While some processed food consumption will have little negative effects on your health, consuming a lot of processed food can adversely affect your health long-term. Additives such as sodium and sugar are prevalent in processed foods. Over consumption of sodium can hurt your brain, kidneys, bones, liver, heart, skin and stomach. Too much sugar can lead to obesity and unhealthy teeth and can even lead to liver problems or diabetes.
