You are What Your Father Ate, too

Research has shown that what your mother ate during pregnancy can affect your health. But a new study shows that mice whose fathers were fed low-protein diet show distinct and reproducible changes in the activity of key metabolic genes.

The fathers never saw their offspring and spent minimal time with their mothers, but the changes still occurred. This suggests that nutritional information is passed on to the next generation via the sperm.

Science Daily reports:

"The new findings ... add to evidence that epigenetic reprogramming of genes may be an important mechanism for passing information about the environment, and in this case the nutritional environment, from one generation to the next. Epigenetics refers to heritable chemical modifications to DNA".
