The advice to eat a healthy diet is not new. Back around 400 B.C., Hippocrates, the Greek doctor, had this missive: Let food be thy medicine.
But as a society, we've got a long way to go. About 1 out of every 2 deaths from heart disease, stroke and Type 2 diabetes in the U.S. is linked to a poor diet. That's about 1,000 deaths a day.
