Well, one possibility: Who do you think is more likely to be shopping at a health food store, the person who is ridiculously healthy or the one who feels vaguely rotten? Something motivates people to shop at an alternative food store. I can easily see someone who’s sick being motivated to change their eating habits (or at least hitting up the various nostrums and snake oils that a lot of health food stores sell).

Exactly.
People who shop at health food stores are people who are trying to BECOME healthy, not necessarily people who are only trying to maintain a healthy body.
