Edamame
Ever had edamame soybeans? There are many good reasons to try and keep eating them (they pair well with many dishes), especially if you’re looking to improve the condition of your fingernails.
Edamame is a good source of folate – the body needs this to produce new nail cells. The beans also contain cysteine. This is an amino acid required to produce keratin, a protein that makes up skin, hair, and nails.
