Very cool, if true

There's some nice evidence that teas and even coffee have health benefits (in moderation). Enough that I actually resumed drinking 2 cups of coffee per day, on top of my rather weak green and black tea. I have zero trouble giving it up, and hadn't drunk coffee in years, so it was a deliberate decision. But I'm incredibly insensitive to caffeine, so I don't have any downsides.

I believe there are psychological mechanisms also behind the effect you describe for sweetened things. The sweet taste causes the body to ramp up to receive sugar (as I recall, affecting insulin levels?).

But I think we're in agreement on other sweet drinks. I mean nobody should have them with any regularity, especially kids.
