Moderate consumption of caffeinated coffee or tea was linked to reduced #dementia risk and modest improvements in cognitive outcomes; no benefit was seen for decaffeinated coffee in an observational study of US adults.

A cup (or 2 or 3) of coffee or tea a day helps keep dementia away — Proving that most of what natural foods or drinks people consume in moderation is fine.

Saw the headline, went looking for this, and found it. The headline makes it sound as if the anti-dementia effect is limited to the 2-3 cup range, but it's not. The health benefits of coffee in general seem to be like this— they don't keep increasing with more, but they flatten out.
