In the 1930’s, in a small town in southern California, pediatrician and research scientist Dr. Francis M. Pottenger, Jr., made two discoveries that were nothing less than prophetic. His first discovery revealed that other cats fed a poor diet passed their health problems onto their kittens over three generations. Pottenger’s second discovery was as revolutionary, for he found that it took at least four generations of a healthy diet for kittens to recover from—meaning, to turn around—the health-robbing effects of the poor diet fed to the first generation. Is it really possible to pass on health problems to unborn generations? Is diet-related health status—over generations—relevant to human beings? Conversely, can consuming a healthful diet reverse the trend and turn illness to wellness for ourselves and our offspring? An emerging new state-of-the-art science called epigenetics is offering early answers to questions raised by Pottenger and his prophecy of diet-based wellness or illness decades ago. And recent research is doing even more, for it is providing a crystal ball into the future of food and our health, indeed, into the role diet plays in our survival as a species.
