单项选择题

Questions 17-20 are based on the following conversation about a new snack food.
W: I’ve been reading about a new snack food. It’s made from fish. Have you heard anything about it
M: No, I haven’t, but I don’t like fish very much anyway,
W: Not to worry. Although it’s made primarily from fish, it actually doesn’t have a fishy taste. In fact, it can be flavored with tomato, cheese, or chocolate for instance.
M: How can it not taste fishy Do you know how this snack food is made
W: First the fish is minced and cooked and fermented.Then water and starch are added to make a dough.
M: It sounds awful.
W: Actually the dough isvery bland at that point, so the flavorings are added to give it some taste.
M: Well, it still sounds a little strange. But I suppose this product will at least be low calorie and high protein, like a health food.
W: Yes, you could call it that.And it has a long shelf life, so it won’t spoil quickly It is also easy to digest and can be made from types of fish that usually aren’t eaten, or from high grade fish by-products.
M: Mm, have you got any samples I might be willing to try the cheese-flavored variety.
W: No, none of it seems to be available yet. As f understand it, this fish snack food probably won’t be in the stores for another couple of years. So you’ll have a while to get used to the whole idea.
M: A couple of years, ah It may just take me that long, but thanks for telling me about it.

What would be a good reason for buying the product（）
