I wondered if he might talk things over with Novak, they're friends I know - in fact there aren't too many people on the tour Andy doesn't get along with - which speaks volumes. Andy is obviously learning about changing/adapting his diet, even if he may not need to be glucan-free, changes could still help him. Good Luck Andy.
Yes he does seem to get on well with almost everyone doesn't he. I imagine some of his fellow players are quite perplexed as to why he's not more popular in his own country (UK that is not Scotland). It could well be that the difference Novak's diet has made to his fitness prompted him to look at his own diet. But it does seem rather odd doesn't it that his fitness coach hadn't thought about this before? Perhaps he's eaten well sports wise but they just hadn't realised it wasn't the right diet for his body. Anyway, really hoping we see the effects over next month or so.
