Diets and fashion: Let’s sort the wheat from the chaff

DIETS, like beards, come in and out of fashion.

Not so very long ago the Atkins diet was advanced as the holy-grail answer to all our weight problems. We’ve had high-fat low-carb diets, we’ve had raw-food diets, blueberry and cranberry diets.

We’ve had the paleo or stone-age diet, we’ve had sugar-free diets and some people even invested time and faith in the clay cleanse diet.
