Diabetes is one of the most widespread diseases of the moment, a metabolism disorder that has grown to reflect some of the deepest vices of modern lifestyle. Type two diabetes, which accounts for the vast majority (about 90%) of all diabetes cases, is closely linked with obesity and physical inactivity. At the moment, diabetes affects 246 million adults worldwide and accounts for six per cent of all global deaths - however, doctors warn that by 2025, 380 million people will be suffering from this disease, as more and more developing nations will adopt the "western" lifestyle of takeaway food, insufficient fruit and vegetable intake and little physical activity.

Under these circumstances, it's not surprising that diabetes is a primary target for widespread global research into whether a change of lifestyle can actually delay or even prevent its development. A recent such study took place in China and showed that a sensible diet and regular exercise reduced the incidence of diabetes by an impressive 43% over 20 years in the 577 adults who participated in the research. "This study has shown that group-based interventions targeting lifestyle changes such as diet and exercise produce a durable and long-lasting reduction in incidence of type 2 diabetes", the researchers wrote in the journal Lancet.

So, what are we to do to avoid or delay the onset of this disease? According to the Chinese and Japanese researchers who contributed to the study, the key words are "improved diet" and "better exercise". Drinking less alcohol and eating more fresh fruit and vegetables is a first step,and it's essential to turn these healthy diet habits into an everyday routine. The struggle against diabetes is a long-term process, so eating fresh vegetables for a month every year won't do the trick. Exercise is also a key factor, but it has to be done regularly for the rest of our lives. "The challenge is to translate research findings into substantial clinical improvements for patients", the researchers wrote in their published work. It may not be a certified cure, but it's a very promising beginning.
