Christmas cake is full of dried fruit and often made with the fruit soaked in more fruit juice.
What's wrong with that I hear you ask?
Fructose is what's wrong. If you read my November letter reviewing the book "Sweet Poison" you will see that sugar - actually the fructose in sugar is toxic to your body and can cause many chronic illnesses. As dried fruit and fruit juice contain concentrated fructose, they are the worst things to consume - particularly at a time of year when you are probably overindulging with other things such as rich dinners and alcohol.
So take my advice and give the fruit cake (and fruit mince pies) a miss this Christmas. Your body (and wastleline) will thank you for it.
