A new study shows ‘a significant reduction in the level of stress’ with 500ml of daily pomegranate. What else would help? I got properly drenched on the way to the station this morning, then my train was delayed by 20 minutes en route to the office – hardly the most becalming of starts to the week. So having arrived at my desk holding a large, caffeinated cup of coffee, my eye was turned by a study from Queen Margaret University, Edinburgh, claiming my stress levels at work could be reduced by drinking more pomegranate juice.
