Here is a rare and welcome thing: a piece of dietary news that revised in the generous direction. The American Heart Association now says up to five cups of coffee a day are safe for most adults — and may actually be good for the heart.
Five cups. Not a guilty two, not a hedged three — five, with a cardiac upside penciled in. After years of health guidance that only ever tightened, an official body looked at the evidence and loosened the rule.
Which is the whole reason it earned a spot in this edition. Evidence changed, and the honest response was to update the position rather than defend the old one.
Here is the part worth saying plainly for the book. The cardiologists just did the thing we ask of every position: they let new evidence overrule an old, comfortable conclusion, without sentiment. That is the entire job — when the facts move, move with them, and do not fall in love with the holding you are leaving or the rule you are rewriting. It is a low-stakes place to practice a high-stakes discipline, which is roughly the nicest thing you can say about a second cup of coffee.
No trade, obviously — unless you count the second cup. Filed under the one discipline that travels from a health panel to a portfolio: when the facts move, move with them, and do not get sentimental about the position you are leaving. Also, enjoy the coffee.
