Men who gorge on junk food could be condemning their future children to diabetes, research suggests.
The warning comes as Britain fights an epidemic of type 2 diabetes, with some two million already diagnosed and the figure forecast to double by 2025.
Another seven-million are on the borderline of the condition which usually comes on in middle age and greatly raises the odds of heart disease, stroke and amputation and can shorten lifespan by 10 years.
Much of the rise of the disease has been blamed on expanding waistlines. But the latest research suggests that at least some of the seeds of destruction could be sown in previous generations.
It also suggests that prospective fathers should keep an eye on their diet, in the same way as mothers-to-be do.
The Australian and American researchers fed young male rats a high-fat diet, mated them with healthy females and tracked the health of the female pups they went on to sire as adults.
The 'daughters' developed diabetes before they reached puberty, with blood glucose concentrations double those of pups born to normally-fed males.
The junk-food rats' daughters also produced half the amount of insulin, the hormone that regulates blood sugar levels and is key to the development of diabetes, the journal Nature reports.
