Which of the following is NOT a characteristic of healthy nails?

Discoloration is not a characteristic of healthy nails. Healthy nails typically exhibit a consistent color that is uniform and free from spots or color variations. Changes in color can indicate underlying health issues, such as fungal infections, nutritional deficiencies, or other medical conditions. When nails are healthy, they tend to be strong and resilient, have a smooth surface, and grow consistently. These characteristics are essential indicators of overall nail health and can reflect the individual’s general health and hygiene practices.
