Dairy products such as milk, cheese and yoghurt appear to help prevent type 2 diabetes, the 'lifestyle' form of the disease, say researchers from Cambridge University.
However, they're not entirely sure if dairy has a direct protective effect or whether they are consumed as part of a healthier diet.
If it's because of the foods themselves, it's all to do with their atomic numbers, it seems. Foods, such as dairy, that have odd carbon atoms-such as 15 or 17-have a protective effect, while those with even numbers, such as 14, 16 and 18, appear to help cause diabetes.
The researchers base their theory on a review of 12,403 people with type 2 diabetes, who were compared with a group of 16,154 healthy people.
