Tea fans may want to pay more attention to the quality of their teabags, as new research has suggested that cheaper bags contain high levels of fluoride and are potentially damaging to your health.
In the UK, tea drinking is one of the few edible pleasures we have left that isn’t unhealthy or fattening, but it seems that the humble teabag could be hiding a dark secret.
Researchers at Derby University measured the levels of fluoride in supermarket own-brand teabags by looking at the amount found in a litre of tea, the equivalent of four cups a day. It’s the amount the average Briton drinks a day. (And we don’t know about your office, but around here four cups would be the bare minimum to get us through the day.)
On average, the level of fluoride in own-brand teabags was 6mg. The recommended daily amount (taken from US recommendations as there a recurrently none in the UK for fluoride) is just 4mg. Only Waitrose’s own brand teabags were below this, with 3.6mg of fluoride per litre found.
