My fingernails have always been healthy and continue to be healthy on this diet. I don't pay enough attention to say for sure but I believe they are growing a bit faster than before. I cut them and file them, while keeping my thumb and four nails on my right hand longer than the rest for playing classical guitar. They never break or chip. One time I even bent back my longer thumbnail doing a judo throw right in the middle of the nail and it bled for a little while and everyone said it would fall off eventually and it didn't. The bent part you could see because there was dried blood under it, and it grew out and never fell off.
