Dr Trombetti says she hates the stuff herself - but points to a welter of scientific evidence to back her case. Coffee contains tannin and antioxidants, which are good for the heart and arteries, she says. It can relieve headaches. It is good for the liver - and can help prevent cirrhosis and gallstones. And the caffeine in coffee can reduce the risk of asthma attacks - and help improve circulation within the heart.
There is no denying that coffee is not for everyone. If you drink too much it can increase nervousness, and cause rapid heartbeat and trembling hands. Pregnant women, heart patients, and anyone with a stomach ulcer are usually advised to avoid it. And even Dr Trombetti says no one should drink more than three or four cups a day.
