Americans drink a lot of coffee. Like, a lot. Roughly 80 to 85 percent of Americans drink coffee on a regular basis, according to the American Psychological Association, and the average daily intake is somewhere around 300 milligrams. That’s about three (eight-ounce) cups of plain coffee, if you’re wondering.
But when it comes to how much coffee is recommended per day, the jury has been back and forth for a while. The 2012 recommendation from the Food and Drug Administration warns adults from exceeding 300 milligrams of coffee a day. As does the recommendation from the International Food Information Council.
Now, a new study published in the journal Food and Chemical Toxicology reviewed 15 years of data to find that consumers can actually safely exceed 300 milligrams a day. Specifically, the average healthy adult can go up to 400 milligrams of caffeine without doing any damage, while pregnant women should stay within 300 milligrams.
