We could do a lot to improve public health and reduce runaway medical expenses if we focussed more on preventing disease and less on medical fixes, says Gary Bennett.

From Duke University, this is “Glad You Asked,” where we consider the question, “What should we be talking about this election season?”
"I’m Gary Bennett. I’m a professor of psychology and neuroscience at Duke. I think we should be talking about the idea that good policy is better than medicine. The problem that we have in the U.S. right now is that we have healthcare costs that are just spiraling completely out of control. And this is really unsustainable.
And if you look at what we’re dying of, there are things like cardiovascular disease, cancer, diabetes. These are all mostly preventable conditions. And then the burden of those conditions falls disproportionately on the poor. And if you can’t get behind the moral imperative to fix that problem, then I think you have to get behind the economic one, which is, we just can’t afford it.
The good news here is that if you look at these leading killers, you can seriously mitigate your risk by doing some extremely common sense, very simple things. Things like never smoking, losing weight, eating a healthy diet and being physically active. For those four conditions, we have good treatments. But they all require high levels of motivation. And we know that a lot of the American population just is not motivated to improve their obesity and their diet and their physical activity and their smoking rates.
And that’s where good policy comes in. Because good policy can help to structure environments in a way that the default choice is always a healthy choice. So we really need to be thinking about the kinds of policies that can make our world a place where it’s easier to be healthier. In the area of physical activity, what would really help is for us to create neighborhoods that had greater street connectivity, to increase the number of sidewalks, to increase our bike lanes, to really make our physical environments conducive to physical activity. And that requires good public policy. It requires investments in our physical infrastructure.
In the area of obesity, we have good examples here in North Carolina of policies that are designed to make it easier for corner store operators to offer healthy fruits and vegetables. These are really important policies that can add meaningfully to the health of Americans."
