Fruit consumption and risk of type 2 diabetes: results from three prospective longitudinal cohort studies

In primary and secondary care, doctors often advocate that patients eat healthily. Patients’ diets can have dramatic effects on their long term health outcomes.
WHO recommends a minimum intake of 400g of fruit and vegetables per day (excluding potatoes and other starchy tubers) for the prevention of chronic diseases such as heart disease, cancer, diabetes, and obesity.1 As the average serving of fruit or vegetables is approximately 80 g, this minimum intake is commonly communicated as “five a day”. However, not all fruits and vegetables will have the same effect, and some chronic diseases will be more affected by diet than others.
The authors of this study were interested specifically in the prevention of diabetes. Their primary research question was, essentially, “Are all fruits created equal in the purported powers to prevent type 2 diabetes?”
The authors also looked at the effect of consuming whole fruits instead of fruit juices,
