As part of a heart smart diet, salmon contains omega-3 fatty acids, protein and biotin. When consumed, biotin prevents nails from becoming brittle.
An apple a day may keep the doctor away, but citrus foods, such as oranges, encourage nail growth while restocking the body’s folic acid levels.

Milk is another excellent source of protein as well as calcium, so choose low-fat options to keep nails healthy and strong.
