A dad's sperm affects his son's metabolism, Nature study says

I'm always on the lookout for illustrations that might find some use in the classroom. Here's one, for example, about how diet affects epigenetic expression. 

A dad’s sperm records his diet — and this record affects his sons’ metabolism, according to a study of mice and humans.

Giving male mice a high-fat diet raises levels of some types of RNA in their sperm, the study found. The research also showed that the male offspring of male mice on this unhealthy diet had metabolic problems such as glucose intolerance, a characteristic of diabetes. The sons of human dads with a high body mass index (BMI) exhibited similar problems, according to epidemiological analysis.

The study was published in Nature on 6 June.
