And Americans are sick — much sicker than many realize. More than 100 million adults — almost half the entire adult population — have pre-diabetes or diabetes. Cardiovascular disease afflicts about 122 million people and causes roughly 840,000 deaths each year, or about 2,300 deaths each day. Three in four adults are overweight or obese. More Americans are sick, in other words, than are healthy. Instead of debating who should pay for all this, no one is asking the far more simple and imperative question: What is making us so sick, and how can we reverse this so we need less health care? The answer is staring us in the face, on average three times a day: our food.
