Aoife Hearne: My son eats lots of dairy but has brittle nails, what else should we do?

"Our nails are primarily made of the protein keratin - protein is essential for growth and repair, so it plays a vital role in all our cells."

Brittle nails are a common complaint and affect up to 20% of the population.

My teenage son’s nails have become quite brittle. He eats plenty of dairy products, mostly milk and cheese. What other foods does he need to consume?
