Storm in a teacup?

A large volume of research has linked daily caffeine consumption (usually more than 150mg) with miscarriage. But no one is yet able to say with certainty how or why caffeine causes miscarriage.

Although the risk may not necessarily apply to all women, it is of particular importance to women who are prone to miscarriage. They may be particularly sensitive to the effects of caffeine and, armed with this information, may feel they would like to try cutting down.

Whether you’re pregnant or not, high consumption of caffeine is not a healthy habit. Physiologically, the side effects can run the gamut from heart palpitations to high blood pressure. It has been implicated in everything from cancer and heart disease to osteoporosis. And while some people find that caffeine gives them a buzz, others say it makes them tense, anxious and headachy.

If you’re interested in cutting down your caffeine consumption there are plenty of alternatives

The most obvious choice is a decaffeinated version of your favourite brew. Green tea is also very low in caffeine, as are herbal teas. Another alternative is herbal coffee made from roasted herbs such as chicory, carob, barley and betel nut, which can be ground and brewed.

Whichever way you choose to go, the key appears to be conscious consumption – if you don’t let caffeine become a habit, it’s unlikely to be a problem.
