how many cups of coffee is safe to drink?

I was traveling today and found a very interestign article in the airport (I didn't have much time to read and money to buy the journal for 23eur.) so next what I did - I asked my CHATGPT 😁 and explained that this articel was written that the FDA did some kind a research about a coffein and how many cups per day you should only drink, here's what it found:

Fresh update (this month): the American Heart Association just published a big review in Circulation and moved the number up. Their statement now says up to 400 mg of caffeine/day, equivalent to up to 5 cups of caffeinated coffee, is generally safe for most adults and appears linked to a lower risk of several cardiovascular conditions including heart failure and stroke. That's a shift from the old "3-4 cups" framing that used to circulate. American Heart Association

Worth knowing before you set your own limit:

• The 5-cup upper limit is intended for most healthy adults — pregnant women, people with caffeine sensitivity, certain arrhythmia patients, and people managing LDL cholesterol should discuss coffee intake with a clinician. Medical DailyMedical Daily

• On blood pressure specifically, the picture is nuanced: drinking one to three cups per day was associated with a slightly increased risk of developing high blood pressure in people who currently have optimal readings, while more than three cups per day was associated with a lower risk.

• All caffeine sources stack — energy drinks and espresso count toward the same daily budget, so if you're also drinking Red Bull or espresso shots on top of drip coffee, subtract those from your "cups" count. Barista Life

• Add-ins matter: added sugar, flavored syrups, milk or cream may reduce coffee's potential health benefits or lead to negative outcomes. Daily Coffee News

Bottom line: 4-5 cups of plain black coffee (roughly 400mg caffeine) is the number to work with as a healthy adult. Given your marathon training, worth noting caffeine timing also affects sleep and recovery — if you're doing hard morning runs, cutting off caffeine after early afternoon helps more than the total cup count does.
