Fast Food and diabetes link

Fast food, sometimes considered a major contributory factor in the spread of obesity throughout the developed (and increasingly the developing) world, leads to weight gain and an increased likelihood of developing type 2 diabetes.
Type 2 is usually caused by an inherited pre-condition coupled with environmental factors such as diet and lifestyle. The sedentary lifestyle typified by developed nations such as America is perceived as being partially responsible for the diabetes pandemic sweeping the entire world. Fast food is one aspect of this.
A study, conducted by researchers at the University of Minnesota, took data from over 3,000 American adults. The study group reported their eating habits, including fast food over the course of 15 years. Results indicated that the frequency of fast food consumption was a major factor in weight gain. Subjects who ate fast food regularly (more than twice per week) were shown to double their insulin resistance.
Researchers do not consider fast food to be the exclusive cause of the widespread occurrence of obesity and diabetes. Further lifestyle factors were also attributed including alcohol, indolence and television, and a generally less healthy diet. The links between diet and diabetes are once again reinforced.
