Food abundance, on the other hand, was associated with a greatly shortened lifespan of the grandchildren. Early death was the result of either diabetes or heart disease.

Nutrition & the Epigenome

Could it be that during this critical period of development for the grandfather, epigenetic mechanisms are "capturing" nutritional information about the environment to pass on to the next generation? Food abundance for the grandfather was associated with a reduced lifespan for his grandchildren. As we better understand the connections between diet and the epigenome, the opportunity arises for clinical applications.

Just as mapping our gene variations gives us a window into our personalized medical needs, so might a profile of one's unique epigenome. Formed through a lifetime of experiences beginning in the womb, our epigenome may provide a wealth of information about how to eat better.

Enter the future field of nutrigenomics, where nutritionists take a look at your methylation pattern and design a personalized nutrition plan. While we're not quite to that point yet, your doctor can already tell a lot about the your disease risk by looking at your family health history. Royal jelly is a complex, protein-rich substance secreted from glands on the heads of worker bees. A larva destined to become a queen is fed large amounts of royal jelly inside a compartment called a queen cup. The larvae that develop into workers and queens are genetically identical. But because of her royal jelly diet, the queen will develop ovaries and a larger abdomen for egg laying, while the worker will be sterile.

She'll also develop queenly behaviors: the instincts to kill rival queens, make communication sounds known as "piping," and go on "mating flights. In a series of experiments, scientists determined that royal jelly silences a key gene Dnmt3 , which codes for an enzyme that silences a group of queen genes.

When Dnmt3 is turned "on," the queen genes are epigenetically silenced, and the larvae develop into the default "worker" variety. But when royal jelly turns Dnmt3 "off," the queen genes jump into action, turning the larvae into queens. Queen Bee Larvae: Queens are raised in specially constructed cells called "queen cups," which are filled with royal jelly.
