Your fingernails can divulge information about your general health. Because nails grow quickly, they often show visible signs of nutritional problems before other tissues do. Fingernail ridges can indicate vitamin or mineral deficiencies as well as general malnutrition or other illness if they run horizontally, but are usually benign if they run vertically. Nutritional deficiencies can also cause fingernails to become misshapen, discolored or brittle, breaking easily. See your doctor if you notice changes in your fingernails. prom selections in black
