We’re a nation fuelled by caffeine. We drink about 100 million cups of tea a day, according to the UK Tea & Infusions Association; and, says the British Coffee Association, somewhere in the region of 95 million cups of coffee. And that’s before we even mention energy drinks.

Yet the health advice surrounding caffeine can sometimes be confusing. A study published in BMJ Evidence-Based Medicine found that pregnant women should cut out caffeine completely to help avoid miscarriage, low birth weight and stillbirth. This is in contradiction to the current guidance in the UK, which states that a daily caffeine intake equivalent to two cups of medium-strength coffee (200mg) is safe for pregnant women.
