A study of credibility?

A recent Ananova article suggested that eating cheese before you go to bed can help you have a good night sleep. Well that sounds reasonable enough - but how can they be sure? Well, perhaps the British Cheese Board could commission a study? Which is what they did. Two hundred people ate cheese before bedtime for a week and 72 per cent slept well say researchers. And why was that so? Scientists say cheese contains an amino acid called tryptophan which reduces stress and aids sleep. Perhaps there's an ice cream board out there that wants to field a similar study. If so, I hope they know where to find me!
