Everyone is different. I know a few people who have severe caffeine addiction. It can be addictive, yes, it can impair your immune system, it can kill the beneficial bacteria in your gut, it can contribute to fatigue. And some people can tolerate lots with no effects. It’s like the butter and eggs scare. We are free to consume. Myself, I drink a cup a day in the morning. I like a low acid coffee that is not very strong. I also take cream and sweetener. I drink it because I enjoy it. These studies are a waste of money IMO and it always seems like there is an agenda behind them. We just need to make care of ourselves and pay attention to what we eat and drink, instead of being mindless. Rant over.
