The nails in your fingers and toes are important functional parts of your body. Brittle nails have a tendency to break or tear easily, which can be very painful. The appearance and strength of your nails are directly related to the types of food you eat, so strive for a balanced diet that's rich in vitamins and minerals.
Description of the Nail
Nails exist at the tips of your fingers and nails to help protect the nerve endings in these parts of the body, provide additional structural support to prevent damage or injury and to assist in the functions of gripping, holding and tearing. The body of the nail is made up of a clear structural protein called keratin, which gives the nail its strength, luster and water-resistant characteristics. The appearance of the nail can vary due to diet, genetics, climate, age, fitness level and gender.
Significance
Brittle nails can be weak, thin, yellowish-colored or may grow slowly. Brittle nails have a tendency to break, crack, split or tear easily. One particular characteristic of brittle nails is the appearance of small ridges that run from the top to the bottom of the nail. The cuticles, or the skin surrounding the nail plate, may also be sensitive and dry.
Causes
Malnutrition and eating disorders can cause a deficiency in vitamins and minerals that promote protein development in the nails. You may suffer from brittle nails if your diet is deficient in protein, calcium, B vitamins, vitamin C or folic acid. MedlinePlus explains that low levels of zinc and iron as well as thyroid problems may cause brittle nails, though aging is the most common factor. Diets that contain high amounts of saturated fats and insufficient amounts of essential fatty acids can affect the appearance of the nail.
Treatment
Nutrition is one of the major factors in developing strong, healthy nails. Strive for a diet rich in protein, iron, calcium, folic acid, vitamin C and B vitamins. Dairy products such as yogurt, dark green leafy vegetables, almonds, beans and oranges are ideal foods that can help improve and strengthen the condition of your nails. Seafood is a good source of zinc and essential fatty acids. The American Osteopathic College of Dermatology suggests taking 2.5mg Bioton, a B vitamin that promotes protein growth in hair and nails.
Warning
If simple home remedies don't improve the condition of your nails, you may need to speak with your doctor. Discolored and misshapen nails can sometimes be a sign of fungal infection or other diseases that your doctor can assess and diagnose.
