Good news:
Drinking several cups of tea or coffee a day appears to protect against heart disease, a 13-year-long study [of 40,000 people] from the Netherlands has found.
Less good news:
Consuming between two to four coffees a day was also linked to a reduced risk... the protective effect ceased with more than four cups of coffee a day,
But at least:
even those who drank this much were no more likely to die of any cause, including stroke and cancer, than those who abstained.
