I first thought this was about the worst tasting food or worst value but they are talking about health. Why didn’t they just say that to start with.
BTW, the worst meal I ever had at a Restaurant was Po folks in Jackson Mississippi, maybe 20 years ago. Oddly enough the one in Dothan, Alabama was real good.
I don't make any effort to seek out such articles, but I do see them from time to time. I've seen enough to assume nowadays that if some article's about the "worst" foods, drinks, meals, or something like that, it's a sermon about What We Shouldn't Put in Our Mouths.
On occasion, I'm pleasantly proved wrong and the article's more like what you thought, but that kind of thing is clearly the exception in these enlightened days.
