Nails covered in little white marks? Science is here to explain WHY

Much like we thought hovering a buttercup beneath our chin as children would indicate our affinity for the dairy product, we were also brought up to believe that those small white marks on our nails suggested a lack of calcium.

But it turns out – like the buttercup fiasco of the 90s- one has absolutely no bearing on the other.

According to the good folk from the world of science, the small white marks which most of us ignore by painting over are, in most cases, a result of minor trauma – so minor it's likely we didn't even notice it happening.

With the help of a handy science lesson on YouTube, we soon learned that these marks – which are actually known as punctate leokonychia – have very little to do with how much milk you drink.
