Black coffee is a morning elixir, helping people wake up and provide a jolt of energy. It\u2019s famous for caffeine, of course, but it also comes with some impressive health benefits.<\/p>\n
Americans love the dark brew: Roughly two-thirds, 66%, report drinking coffee in the past day \u2014 more than any other beverage including plain water, according to a 2025 report from the National Coffee Association, up 7% since 2020.<\/p>\n
Take a sip and you will feel the effects right away: The caffeine in coffee is a central nervous system stimulant, \u201cspeeding everything up\u201d in the body and brain, according to the American Medical Association.<\/p>\n
\u201cIt will increase your energy levels. It can also decrease feelings of fatigue,\u201d Lisa Young, Ph.D., a registered dietitian and adjunct professor of nutrition at New York University, tells TODAY.com. She\u2019s the author of \u201cFinally Full, Finally Slim.\u201d<\/p>\n
Research also points to a positive impact on heart health, brain health, weight loss and mood, Young adds.<\/p>\n
A recent study found that drinking caffeinated coffee may prevent recurrence of atrial fibrillation in people who have the condition but have been managing it. People who drank at least one cup a day were less likely to have a recurrence and had a longer period on average before their next episode.<\/p>\n
Another study, published in the Journal of Clinical Endocrinology & Metabolism in September 2024, found moderate caffeine intake may protect against Type 2 diabetes, coronary heart disease and stroke.<\/p>\n
But it\u2019s not about refilling all day long. Drinking two to three cups of coffee was the \u201csweet spot,\u201d the researchers concluded, according to NBC News.<\/p>\n
And another study suggests coffee has the most benefits when you drink it in the morning. The research, published in January 2025 in the European Heart Journal, found that drinking coffee before noon leads to a 31% decrease in risk of dying from cardiovascular disease and 16% lower risk of death from any cause compared to those who don\u2019t drink coffee. For all-day coffee drinks, there was no decrease in cardiovascular disease risk compared to non-drinkers.<\/p>\n
\u201cThere are benefits to coffee. \u2026 But if you are a coffee drinker, I still think you should watch how much you drink,\u201d Young advises.<\/p>\n
Black coffee has virtually no calories or fat as long as you don\u2019t add cream or sugar to the beverage.<\/p>\n
One cup of brewed coffee prepared with water contains the following, according to the U.S. Department of Agriculture:<\/p>\n
Black coffee has no carbs, cholesterol or fiber. It contains some calcium, magnesium, niacin, phosphorus and folate.<\/p>\n
Adding milk and sugar \u201ctotally, totally changes the equation,\u201d inserting fat and calories, which can counteract any positive health effects, Young warns.<\/p>\n
Coffee beans have more than 100 biologically active compounds, including powerful antioxidants. These compounds can help reduce inflammation, improve insulin sensitivity, boost metabolism, inhibit the gut\u2019s absorption of fat and block receptors involved with abnormal heart rhythms, according to research presented to the American College of Cardiology in 2022.<\/p>\n
Two to three cups of coffee a day are associated with a longer life, and a lower risk of heart disease and heart rhythm problems, three studies found.<\/p>\n
The benefits applied to both people with and without heart disease.<\/p>\n
Moderate coffee drinkers who drank two to three cups per day were almost 50% less likely to develop cardiometabolic disease than people who consumed a cup a day or less, according to the 2024 study.<\/p>\n
Atrial fibrillation is a common condition where the heart beats irregularly, and it can lead to heart failure and stroke. There’s no standard guidance on whether caffeine, which can increase heart rate and blood pressure, is safe to drink when you have a-fib.<\/p>\n
However, a new study published in November 2025 looking at 200 older adults with a history of a-fib that had either been treated or resolved found that people who had a least one cup of coffee a day were less likely to have an a-fib episode than those who didn’t: 47% versus 64%.<\/p>\n
Drinking coffee, especially unsweetened coffee, is linked with a lower risk of death, another study found.<\/p>\n
People who drank 1.5 to 3.5 cups a day without adding sugar were 16% to 21% less likely to die during over seven years than people who didn\u2019t drink coffee at all.<\/p>\n
Moderate consumption of caffeinated coffee may also be part of a weight management strategy, a 2023 study noted, calling the impact an \u201canti-obesity effect.\u201d<\/p>\n
A 2021 study found people who drank four to six cups of coffee a day had a lower incidence of stroke and dementia.<\/p>\n
Too much caffeine can lead to a fast heart rate, anxiety, jitteriness, headache and insomnia, the U.S. Food and Drug Administration cautions. Caffeine also raises blood pressure in the short term, studies have found.<\/p>\n
The FDA says up to 400 milligrams of caffeine a day is safe for most adults. That\u2019s about four 8-ounce cups of brewed coffee. Keep in mind the portions in popular coffee chains are often much bigger, and other foods and drinks contain caffeine, including chocolate and cola.<\/p>\n
If you already drink coffee, like it and tolerate it well, \u201cyou\u2019re in luck\u201d when it comes to the potential health benefits that might come along with it, Young says.<\/p>\n
But if you\u2019re not a coffee drinker now, there\u2019s no need to start drinking it to try to boost health, she advises.<\/p>\n
