You assume that:

1) People know what's good for them

2) People want what's good for them

The existence of an economically viable product such as juice indicates that whatever the industry is doing, people want in its presented form.

Whether it's good for them or not is a completely different question.

Juice isn't really seen as a healthy choice in England. It's pretty much just a soda equivalent over here (in terms of healthiness). People drink it just because it tastes good.

Because juice tastes way better than soda, in my opinion. Only time I like soda is with things like pizza or a burger

Yes that is the point of juice. Why is that surprising? People love cheating, and drinking juice instead of eating fruit is a way to cheat -- get more of the sweet and less of the bland fiber.

You have never felt the desire for a tart citrus beverage?

Not since I came to understand what fruit juice actually is. If I want health I'll eat the actual fruit, and if I want a tasty-but-unhealthy drink I just drink soda.

Sure, the stuff tastes OK, but not as good as the fruit it comes from.

That's the thing, I love fresh orange juice. It tastes great. I do not really like Orange juice and I absolutely loath soda (it tastes awful). So I drink Orange Juice (and Apple Juice) because it tastes great.

Better than the actual orange?

Better brands of orange juice are more refreshing than the terrible, fibrous oranges that are available here for most of the year. I'd rather drink lemonade than eat a lemon, too, for that matter.

What's wrong with smoothies? Blended fruit gives you all the fiber in the pulp and it's super convenient to consume.

I don't really like them, but it seems like a decent way to go if you do.

Yes, exactly. I didn't drink much juice before I read this, but I stopped entirely after first reading it back in 2011.

It tastes good.
