I can vouch for the benefit of eating Jello if you have fingernail issues. Every time I was pregnant I craved Jello. I don't know why, but I did. My fingernails were the healthiest they had ever been. A few years ago, as I got older, (ahem) and after foolishly doing the acrylic nail thing, I started having problems with my nails again and remembered the results of the pregnancy craving and solution so I startd eating Jello every day. It worked again. My nails are in great condition so I will continue to injest the jiggly stuff everyday.
