OR rather two. And one of salt. Just for good measure. I’m not a dieter, by nature or inclination. I rarely crave an apple, or wonder where my next orange is coming from. And it’s not just vanity or the full-length mirror that’s convinced me I need to lose weight, but a scary Channel 4 documentary last week about teenage girls having their stomachs stapled to stop them eating or in extreme cases – and these were extreme – dying. So I embarked with a reasonable degree of enthusiasm on a healthy eating regime. Last night it was a stir fry – lots of healthy veg and free range chicken cooked in olive oil. It looked a bit bland, so I ferreted around in the back of the cupboard and came up with a small jar of Hoi Sin and sesame sauce. It looked vaguely Chinese and had a blue dragon on, which must mean something. It was only after we’d eaten it that I checked the ingredients: 16.2g of sugar and 1.6 of sodium (roughly equivalent to 4g of salt) per 100 grams. The tiny jar held twice that amount, at 200g. Quite a lot of sugar and salt in one supposedly healthy meal.
