Just like any other foods, coffee must be consumed in moderation. For its true health benefits to be achieved, it cannot have a ton of unhealthy additions such as a lot of heavy cream or sugary syrups in it. According to Johns Hopkins, research shows evidence that coffee, in moderation, can link to many health benefits. These include reduced risk of contracting Alzheimer's, strokes, colon cancer, Parkinson's disease, heart failure, diabetes, kidney disease, and more ("9 Reasons Why (the Right Amount of) Coffee is Good for You"). Cleveland Clinic also provides research showing evidence that coffee can be a source of nutrients, "including B vitamins, potassium, and riboflavin", and provides many antioxidants ("This Should Perk You Up: The Surprising Health Benefits of Coffee").
