Nails

Protein and iron, a mineral, are important to nail health.
For protein sources, you can eat meat, poultry, fish and other sources such as soy, while iron can be found in oysters, lentils and iron-fortified cereals.
Along with protein and iron, think about biotin. Biotin, a water soluble B vitamin, may help strengthen nails. Biotin can be found in foods such as eggs, broccoli and fish.
