Is coffee good for you? The evidence, explained

Coffee has been called both a health risk and a superfood over the years. The truth, as usual, sits in the middle. Here's a balanced look at what the research generally suggests — though for anything specific to you, it's always worth speaking to a doctor.

The potential upsides

For most healthy adults, moderate coffee drinking is generally considered safe and may come with benefits. Research has associated regular, moderate coffee consumption with things like improved alertness and concentration (thanks to caffeine), and some large studies link it with a lower risk of certain conditions. Coffee also contains antioxidants. It's worth stressing these are broad population-level associations, not guarantees for any individual.

The things to watch

• Sleep: caffeine lingers for hours, so afternoon and evening coffee can disrupt sleep. A decaf pod is a great evening swap.
• Anxiety and jitters: too much caffeine can cause the shakes or a racing heart in sensitive people.
• What you add: a lot of coffee's "downside" is really the syrups, sugar and cream — the coffee itself is virtually calorie-free.

How much is sensible?

Common health guidance suggests up to around 400mg of caffeine a day is fine for most adults — very roughly four to five espressos — with lower limits often advised during pregnancy. Everyone's tolerance is different. Our guide to how much caffeine is in coffee helps you keep track.

The takeaway

For most people, coffee in moderation is a perfectly reasonable part of a healthy lifestyle — and choosing good-quality coffee you enjoy black or with milk (rather than sugary shop drinks) is the healthiest way to drink it. If you have specific health concerns or are pregnant, check with your GP.
