CHOCOLOGIC NO ADDED SUGAR DARK CHOCOLATE

100g, £1.20, tesco.com. Cocoa: 55 per cent. Per 100g: Calories, 432; saturated fat, 21.9g; protein, 5.3g; fibre, 34.8g; sugar, 3.2g; salt, 0.02g

EXPERT VERDICT: ‘Marketed as 90 per cent less sugar compared to similar chocolates. It uses the sugar substitute erythritol, a sugar alcohol. It’s essentially a reinvention of diabetic chocolate with added fibre. It is better for teeth and slightly lower in calories. However, in large amounts, erythritol has a laxative effect.’

TASTE TEST: Slightly crumbly, almost dusty texture. Sweet for a dark chocolate, but there’s no satisfying richness.
