Consuming large quantities of sugar is bad for us. Health authorities are seeking ways to reduce consumption of sugar. Here’s how.

Forget the pseudo science and celebrity endorsements, here is how to tell which diets really weigh up.

Fad diets and questionable nutrition advice are so widespread in the media that we often overlook the best and most basic healthy-eating model.

The Mediterranean diet involves not only what people eat, but also how, where and with whom. As such, it refers to the “art of living”, that is to say, the translation of the Greek word "diaita". In the 20th century, when the eating habits of rural labourers in this region were discovered to be beneficial to their health, many of the more affluent began following their example.

Since time immemorial, humans have tried to improve their health through their diet. This has resulted in ironic turnabouts in beliefs about what constitutes healthy, rich or inadequate food: the Middle Ages feared fresh fruit, the 1950s sung the praises of sugar, the early 21st century demonises gluten, while “100% natural” is just part of the cycle, periodically calling us to order.
