8. Cashews
Nuts are high in protein, plus they contain zinc, which helps nails grow. Be careful when adding them to your diet, though, because they also tend to be high in fat and calories.
9. Dried beans
To prevent nails from cracking, add dried beans to soup. The added fiber will also fill you up at mealtime.
10. Carrots
It never hurts to add some extra veggies to a salad, and carrots are high in vitamin A, an antioxidant that fights off free radical damage.
11. Almonds
For a protein and biotin-rich snack, reach for almonds.
