W: Have you ever stopped to think about how our appetites and eating habits have changed, or for that matter, considered,
how these habits might change in the future? Our guest today is Roger Sabarta, a food scientist who’s done a lot of research in these areas. So Mr Sabarta, what’s one of the biggest changes in eating habits that you’ve found?
M: Well.I’d say that, (22)the biggest change is the amount of eating out that most of us do nowadays. In 1955 the percentage of food budgets spent away from home was 19%, and in 1997 it was 38% and it just keeps going up.
W: I’d never really thought of it, but of course, thinking of my parents and how often they were likely to eat out compared to me in my life, well, it’s a lot different.
M: Exactly. And then kids nowadays eat out even more often.(23)In the same 42 years from 1955 to 1997, fast food consumption increased 166% for teenage boys .
W: 166%? Wow! So teenage boys are eating a lot more fast food than they used to! I’d guess, it probably isn’t all that healthy.
M: Not really. For example, there’s soda and soft drinks versus milk.(24)Nowadays, people drink about twice as much soda as they used to and a lot less milk.
W: And that’s because of eating out so much?
M: Yes, at least to some extent. Of course there are other factors contributing to this.(25)The amount of advertising done by the food and drink industry goes up every year, so that certainly has an effect as well.
W: Well, we have to stop here. Thank you very much, Mr Sabarta.
