The growing philosophies on food

We've swapped our full-cream milk for the skinny stuff, our wholemeal bread for gluten-free. We're drinking litres of water a day, we're buying organic but we're not eating meat, dairy or carbohydrates. Actually, we're not sure what we should eat.

Meanwhile, our waist-lines are expanding, the rate of diabetes is rising, food disorders are increasing among teenagers and the jury is still out on which food philosophy is best.
