Now, listen to Part Two of the interview.
M: Yeah, all seem like good ideas. In your article, you also talked about some obstacles to research on the effectiveness of food markets. Could you talk a little bit more about those?
W: Absolutely. And there are a lot of things about this research that make it difficult to do. So one is just the types of stores we’re dealing with.(6)If we’re talking about these small corner stores in different communities, many of them do not have electronic cash registers. They don’t provide receipts. You want to know whether customers are buying the healthy food that’s being introduced. And that can be tough to determine, at least by just looking at sort of an output of sales like you might be able to do with a larger supermarket. That’s one obstacle.
M: That’s too bad.
W: And another obstacle is whether people are actually eating what they buy.(7)We assume that if people, you know, are buying, say, spinach, then they’re going to eat it. But we’ve also all had, you know, spinach go bad in our refrigerator and thrown it out. So we don’t really know whether people are eating what they buy.
M:(8-1)So what about pricing? Isn’t it more expensive to eat healthier foods?
W:(8-2)A lot of people think that, and it certainly can be a lot more expensive. It really depends on what you eat. It does not have to be more expensive.
M: Well, that’s good to know. Now looking at this study more overall, there’s a key assumption being made in this type of study that may not necessarily be true about the relationship between access to healthier foods and weight. So can you talk about that?
W: Sure.(9)So I mink when people talk about increasing access to healthy foods as a way to make people healthier, basically, to improve overall health, there’s this assumption that if you eat more healthy food, that means you’re going to eat less unhealthy food. So the healthy food is replacing the unhealthy food. And that makes sense, but we really don’t know that it’s true.
M: Alright.(10-1)So is there cause for optimism in the future? What is left to be examined about food markets?
W:(10-2)Yeah. I think that in some ways, we’re actually near the beginning of all of this, because people have only in the last few years been trying to really look systematically at what strategies make a difference. And I think we are certainly seeing hints that we can change eating habits and that people will eat more healthy foods. A lot of people do want to be healthy.
M: Great. Thank you, Jennifer.
W: Thank you. Thanks for having me.
