Large, black, and sweet.

A while back, I saw a study that linked diet soda with obesity (drinking a lot of it = fatter people). Now I see that there may also be a link to depression. "New research suggests that drinking sweetened beverages, especially diet drinks, is associated with an increased risk of depression in adults... ."
Both studies (as always) caution not to draw too much of a hardline conclusion since there is no actual evidence for causality, just evidence of a link. (It could be that obese people are depressed and drink more diet soda, not necessarily that the diet soda leads to depression and obesity.)
At any rate, I'm pointing this out because the study also found "[a]dults who drank coffee had a 10 percent lower risk of depression compared to people who didn't drink any coffee."




 Mmmmmmmm coffee. This totally justifies my stop at Starbucks this morning.
