FIZZY TEA DRINK

Profusion Organic Kombucha

Turmeric, Ginger & Lemon, 330ml, £2.70, health food shops, ocado.com and amazon.co.uk CLAIM: A lightly sparkling fermented green tea drink ‘enhanced with superfoods’. The manufacturer also says it is ‘organic, raw and alive’. VERDICT: Kombucha is made by adding sugar to tea as well as a bacteria and yeast culture, then leaving it for eight to 10 days. Although lots of sugar is used in the home-made version, the fermentation process converts it so the final product is only about 1 per cent sugar, a lot less than many fizzy drinks. However, some commercial options include added sugar, so check the label. This one is 4.5 per cent sugar — with around three teaspoons per bottle. While some might be left over from the ferment, most of it will be added. It’s unpasteurised, so will still contain live bacteria — but the amount is unclear. Including plenty of fibre and vegetables in your diet would be far better for gut bacteria than this.
