"That morning cup of Joe is a daily, practically sacred ritual for many of us. A large body of research has confirmed that a coffee habit is perfectly fine for most people, and may even have some health benefits – from fighting depression in women to lowering the risk of stroke and prostate cancer."

"But is there too much of a good thing?"

"A study published this week in Mayo Clinic Proceedings suggests that when it comes to coffee, too much appears to be more than 28 cups per week, at least if you are under 55."

"The researchers found that younger men who passed the 28 cup weekly threshold – which works out to about 4 cups per day – had a 56 percent increased risk of death from all causes. Younger women who were heavy coffee drinkers had a greater than two-fold increased mortality risk."
