Coffee may be able to count towards your eight glasses of water for the day. Since coffee is mostly water content, drinking it throughout the day can hydrate you in some capacity. Professor Eric Rimm, an expert on nutrition at Harvard, weighed in on this finding, “Water isn’t necessarily better than other beverages, ‘except for those high in added sugars, like a sports drink,’ he says. Coffee is healthier than soda ‘for almost all health reasons.’ Coffee can actually be a great alternative to water, especially when it’s unsweetened, because ‘it is almost without calories.’ Coffee drinkers are gulping nearly all water when consuming black coffee.” The key to hydrating yourself with coffee is to drink it black—flavored coffee, added sugars, milk, powders, etc. change the content of the coffee, making it a high calorie breakfast drink rather than an alternative form to water.
