I noticed a short while after starting to eat “paleo” that my nails were great - shiny and flat as flat.

Yesterday I noticed that they have developed ridges, along the length of the nail from nail bed to finger end. So in 20 months something has changed….

Some finger nails are more ridged than others, but does it indicate a deficiency of something? Or is it of no importance?? They aren’t BIG ridges - more like the grain in wood.
