    Prevalence of diabetes

    WHO estimates that, globally, 422 million adults aged over 18 years were living with diabetes in 2014. In the UK, 2018 statistics state that almost 3.7 million people have been diagnosed with diabetes and 1 million cases remain undiagnosed. This has more than doubled over the last 20 years and 90% of cases will be type 2 diabetes. Another 12.3 million people are at risk of developing diabetes. This used to occur nearly entirely among adults, but now occurs in children too. The majority of type 2 diabetes cases are in fact preventable and often related to poor dietary and lifestyle choices. Diabetes is the leading cause of blindness and amputations in the UK.

    Healthy lifestyle and diabetes

    Being overweight and especially central obesity, is strongly linked to type 2 diabetes. Therefore weight control through regular physical activity and a healthy balanced diet are important.

    Plant based eating and diabetes

    Observational studies show that prevalence of type 2 diabetes is lower in those following a healthful plant-based diet. Data from the Seventh-day Adventist Health Study (including 22,434 men and 38,469 women) found that as the intake of animal products decreased and consumption of plant-based products increased, there was a reduced prevalence of diabetes. Prevalence of type 2 diabetes decreased from 7.6% in non-vegetarians to 2.9% in vegans. This can be explained by the associated lower body mass index of individuals consuming a more plant-based diet.
