We are on the final countdown to Christmas next week. The holidays mean different things to different people. But there are some unifying factors. Nothing to do with religious beliefs, it’s all about food and drink. Plenty will get consumed, and most of it will be unhealthy.Yes, we wait for a whole year to get to the Christmas festivities. You might argue that there is therefore some justification for excessive indulgence. You wouldn’t really be wrong, so long as you watch what goes down your throat. There will be lots of roasts, calories-laden carbs and, cool fizzling and alcoholic drinks to wash everything down. But there will be other choices too. Salads, greens, lots of vegetables and fruits will be aplenty. And so too will be freshly pressed juices and the plain old water. You will be spoilt for choice.
