For healthy nails, be sure to get plenty of quality protein, and take a protein supplement. Eat grains, legumes, oatmeal, nuts, and seeds. Eggs also are a good source of protein, as long as your blood cholesterol levels are not too high.


Eat a diet composed of 50 percent fresh fruits and raw vegetables to supply necessary vitamins, minerals, and enzymes. Eat foods that are rich in sulfur and silicon, such as broccoli, fish, onions, and sea vegetables. Also include in the diet plenty of foods that are high in biotin, such as brewer’s yeast, soy flour, and whole grains.


Drink plenty of quality water and other liquids. Cuts and cracks in the nails may indicate a need for more liquids.


Drinks fresh carrot juice daily. This is high in calcium and phosphorus and is very good for strengthening the nails.


Consume citrus fruits, salt, and vinegar in moderation, if at all. Excessive intake of these foods can result in a protein/ calcium imbalance that may adversely affect the health of the nails.


Supplement your diet with royal jelly, a good source of essential fatty acids, and spirulina or kelp, which are rich in silica, zinc, and B vitamins, and help to strengthen nails.


For splitting nails and/or hangnails, take 2 tablespoons of brewer’s yeast or wheat germ oil daily.


To restore color and texture to brittle, yellowed nails, make a mixture of equal parts of honey, avocado oil, and egg yolk, and add a pinch of salt. Rub the mixture into your nails and cuticles. Leave it on for half an hour, then rinse it off. Repeat this treatment daily. You should begin to see results after about two weeks.


To strengthen the nails, try soaking them in warm olive oil or cider vinegar for ten to twenty minutes daily.


Treat your nails gently. Using them to pry, pick, scrape, or perform tasks such as removing staples can damage them.


Keep your nails relatively short. Nails longer than one-quarter inch  beyond the fingertip break and bend easily.


Do not cut the cuticles. Uncovering the nails this way is harsh and irritating, and may cause infection. Use baby oil or cream and gently push the cuticles back.


Do not pull at hangnails. Cut them with sharp clippers or scissors. Keep your hands moisturized to help prevent hangnails.


If you are diabetic, see your health care provider if your cuticles become inflamed, because the infection can spread.


If you wear nail polish, use a base coat underneath it to prevent yellowing.


Use nail polish removers as little as possible. They contain solvents that leach lipids from the nails and  make them brittle. These solvents are also potentially highly toxic, and can be absorbed through the skin.


Never apply artificial nails over your own. They may look nice for a while, but they destroy the underlying nail. The chemicals and glue used are dangerous to the body, and are readily absorbed through the damaged nail has also been known to contribute to the development of fungal infection of the fingernails.
