The lowdown on gelatin and your fingernails

Everyone knows that gelatin is protein that strengthens fingernails. Too bad everyone’s wrong. Gelatin is produced by treating animal bones with acid, a process that destroys the essential amino acid tryptophan. Surprise:
Bananas are high in tryptophan. Slicing bananas onto your gelatin increases the quality of the protein. Adding milk makes it even better, but that still may not heal your splitting nails. The fastest way to a cure is a visit to the dermatologist, who can tell you whether the problem is an allergy to nail polish, too much time spent washing dishes, a medical problem such as a fungal infection, or just plain peeling nails. Then the dermatologist may prescribe a different nail polish (or none at all), protective gloves, a fungicide (a drug that wipes out fungi), or a lotion product that strengthens the natural glue that holds the layers of your nails together.
