Depending on how sensitive your body is to changes and how much caffeine you’re used to getting, you could feel withdrawal symptoms if you cut down during your switch from coffee to tea. 'It usually happens when you have a significant change like cutting it out, but it could happen as well if you just cut down,' says Angelone. After your body gets used to the change, though, those symptoms will go away. 

Numerous studies have shown that coffee could prevent type 2 diabetes, but scientists haven’t pinned down why. Some think it’s because coffee increases proteins that carry sex hormones such as testosterone and estrogen, which help reduce risk of type 2 diabetes, while others say it’s because coffee increases insulin sensitivity. 'Observational types of studies don’t always come up with a reason. They just say we see it,' says Angelone. 'But when they continue to show the same things, it’s a good sign.' Regardless, you probably won’t get that same level of prevention from tea, she says.
