As I’m sure anyone following these forums is well aware, the latest version of Huel contains a low dose of fluoride. In low doses, fluoride improves the health of bones and teeth. Too much fluoride leads to fluorosis, which damages bones and teeth. Dental fluorosis tends to occur when teeth are still developing, and children are probably more vulnerable to overdoses of fluoride.
It’s very difficult to calculate total fluoride intake. WHO only seem to provide recommendations for the amount of fluoride that should be present in drinking water. Their recommendation is 1.5 mg per litre of water. Most parts of the UK either have this level naturally or add it to the water. Given that we consume aprox 2.5 litres per day, this gives us about 3.75 mg of fluoride from our water. A day’s worth of Huel contains 3.5mg of fluoride, almost doubling your intake from water. I don’t really want to get into the “is this good for adults?” debate, but it seems like a bad idea for anyone who is still developing teeth.
More than happy to be shown evidence to the contrary.
