It isn't hard to see why this might be so when you consider that it is only within the last couple of hundred years - a blink of an eye in evolutionary terms - that mass food manufacturing has become a part of our world. Our bodies developed to process whole, natural foods so it is hardly surprising that they struggle with the barrage of chemicals they now face.
Besides the almost unpronounceable substances that you will find on practically every food label, one of the worst problems is the prevalence of sugar in processed food. Manufacturers have two main aims for their products, palatability and good shelf-life, and as sugar is key in attaining both, it finds its way into a vast amount of foodstuffs. The net result is that we end up eating far more sugar than we are aware of, and in sensitive individuals that means almost inevitable weight-gain and associated health problems.
So the first aim of anyone wishing to lose weight or gain health should be to remove as much processed food from their diet as they can. In as far as possible, make your meals from scratch using whole foods, don't be lured by fast-food and takeaway outlets and throw out any junk food in the house, and then you will know exactly what is going into your body.
