I: Can you tell us a little about superfoods? W: Well, um, superfoods include tomatoes, broccoli and spinach. I: Hmm. W: These have lots of vitamins, and they are really good for you. I: Right. W: Anyway, they may improve our health, but I don’t think superfoods will be the answer to our eating problems in the future. I: Can you tell us why not? W: Well, the most important thing is to eat healthy food every day. I: Um, right. W: And this is more important than the idea of superfoods. Eating an apple a day is better for you than eating a kilo of spinach one day a week. I: I see. So what you’re saying is … I: There’s been a lot of talk about food pills. W: Yes. I: Are they healthier than other types of food? Could they be the food of the future? W: Well, in the past astronauts ate a type of food pill when they were in space. It was dried food and they added water to it. I: Right. W: But I don’t think food pills will replace normal food. I: Right. Why’s that? For health reasons or social reasons? W: Well, cooking and eating together is an important part of family life and it always will be. You sit down together at a table and you eat and talk. It’s a very old tradition, and eating pills isn’t the same. I: Hmm, so we won’t eat only food pills? W: Food pills might become more popular, but no, we won’t eat only food pills in the future. I: Well, that’s interesting because I was reading about … W: In the future we may have special food that can change its flavor. I: Can you give an example? W: For example, imagine you like chocolate ice cream, but your friend likes strawberry. You eat the same ice cream but it will taste different for both of you. I: The same food that tastes different for different people … W: You’ll think it’s chocolate ice cream and your friend will say it’s strawberry. It might happen with drinks, too. You take a bottle of liquid out of the fridge. You press the button which says “coffee” or “lemonade” or “hot chocolate”. You put the bottle in the microwave and the liquid becomes the drink that you choose. I: So it starts off as the same food or drink, but then we change its flavor by pushing a button. W: That’s right. Just by pushing a button. I: So how does it work? W: Well, this is possible because of nanotechnology. The technology might not replace normal drinks and food, but it may become common in the future. I: And nanotechnology is something that’s used in different areas of science …
