Do the best you can, with what you have, where you are.
Some foods build your health, others cause you harm. We’re entering a season when bad eating has become de rigueur. I doubt anyone will eat and drink only good things between now and the New Year – and we don’t have to. If your basic habits are sound, a little bit of Christmas cake won’t kill you. Pick the best of what’s on offer and enjoy good company. Merry Christmas.
