Two-thirds of Americans drink coffee every single day, according to data collected by the National Coffee Association in 2022, and the debate about how much is too much and whether or not any amount of caffeine is safe persists. But recent research shows that the answer is more complicated than you'd think.

A Harvard study, that followed nearly 50,000 women over the course of 30 years and published in June, found that drinking coffee every day may lead to healthy aging in women. One to three cups a day was also linked to heart health benefits and lower mortality rates.

But research also shows that high coffee consumption can increase your likelihood of dementia. And a 2022 paper published in the Journal of the American Heart Association found a link between heavy coffee consumption and an increased risk of dying from cardiovascular disease in people with hypertension.

Benefits, drawbacks, and the right amount all depend on your individual lifestyle and overall health. And health experts consistently advise that, like with most things, moderation is key for your daily coffee.

Deepak Chopra, author, speaker and proponent of alternative medicine, told CNBC Make It in 2023 that he drinks two to three cups of coffee each day before noon. While that may sound like too much caffeine for the average person, it's actually within a healthy range.
