Like our hair, our nails reflect the state of our health. If your nails break easily, are weak or have white marks on them, they're trying to tell you something: you have nutritional deficiencies! Keep an eye on your nails and adjust your diet accordingly if you're missing out on these nutrients:
Calcium strengthens nails and makes them grow. Feed your nails: Dairy produce, fruit and vegetables and some types of mineral water.
Iron is a fortifying trace element that enriches red blood cells and increases oxygenisation of tissue, especially in nails that break easily. Feed your nails: Red meat, shellfish and pulses.
Sulfur is a misunderstood mineral that's vital for strong nails (it strengthens the nail structure). Feed your nails: Seafood, asparagus, onion, garlic and cabbage.
