Caffeine: We love it, we consume it, and we can't live without it. While we all wish that a cup of coffee could cure the world of all its problems, for some people, it can actually do more harm than good. So, is caffeine actually bad for you?

Dr. Mia Finkelston, MD, a board-certified family physician who treats patients via telehealth app LiveHealth Online, believes the answer changes on a case-by-case basis. "There have been numerous studies that have tried to answer questions about caffeine, and you can find many that support the notion of it being 'bad' for us as well as just as many that boast about its many benefits. For instance, if you experience symptoms from caffeine that impact your physical well-being in a way that it interferes with your work, sleep, exercise, or ability to eat a nutrient-dense diet, then it's probably not good for you."
