> Hu said that moderate coffee intake—about 2–5 cups a day

5 cups of coffee per day is moderate?

The definition of "cup of coffee" used in studies often doesn't match the type of coffee drinks that people consume.

Typically, when someone cites these numbers they're referring to total caffeine intake under 400mg. It would be 5 small cups of mild coffee.

You can exceed this number with a single drink from Starbucks.

True. But if you drink more than that, you should be using bigger cups.
