A new low-fat noodle has sold out within two weeks of being launched into Holland & Barrett.

The Japanese Zero Noodles contain just 10 calories in a 200g pack (rsp: £1.99) and have been a success in the US, Australia, New Zealand and Europe. The carb, sugar and gluten-free noodles are made of 96% water and 3.8% konjack, a root veg containing a substance called glucomannan that is claimed to supress appetite. “Scientific research has shown this ingredient stabilises blood sugar levels and prevents hunger pangs,” said supplier Glow Nutrition.

Holland & Barrett parent NBTY Europe said it was extending distribution fourfold following the sell-out.
