In May, the Observer reported that dietitians have become so worried about claims being made for so-called superfoods that they convened a debate on the subject at the Science Museum. It may be claimed that particular exotic berries boost IQ, energy and immunity, but the only science even vaguely backing this up is that they contain folic acid, which does boost brainpower, but is present in many foods. The antioxidants in pomegranate juice, which supposedly fight diseases as different as cancer and arthritis, actually only last in the body for an hour. Wheatgrass, that standby of the trendy juicebar, is said to be rich in detoxifying chlorophyll, but every green vegetable and leaf in the world contains cholorophyll - which is not, in fact, absorbable by our bodies.
The added irony, in the topsy-turvy world of supermarkets, is that rich desserts often cost very little, while fruit, especially organic, fairtrade, and prepared fruit, is marked up. At the Sainsbury's where I got my lunch, I could have had four 100g creme brulees for 44p, two tiramisu for 98p, and six chocolate mousses for 69p - or a grand total of 11.5p each, making those Pink Lady slices, gram for gram, four times more expensive. We are, more or less willingly, paying through the nose for a particularly 21st-century version of virtue. "You're made to feel worthy, and therefore you're made to pay a premium for it," says Sanders. "Supermarkets have a lot to answer for in the obesity debate.""The way you've got to look at fruit is that it's better to eat fruit than biscuits, cakes and puddings, because there's very little energy value in it and it's not fattening," he says. "A bit of sugar gives you a lift and takes the pangs of hunger away. But it's not full of all sorts of other nutrients as well. That's a myth"
