Coffee
It’s a running joke that scientists change their mind about the pros and cons of coffee every other week. But while that may have been true in the past, the verdict is pretty clear by now: Coffee is not inherently bad for you. There’s even a chance that regular coffee consumption may have some benefits, such as by lowering the risk of heart failure, though we’ll probably need more research to confirm any positive associations. Drinking coffee might worsen anxiety in some people due to the stimulant caffeine. But for the average joe, a cup of joe or two a day won’t hurt.
