I’m a doctor — here are 5 signs your body needs more nutrients

By Tracy Swartz Published Oct. 22, 2024, 5:00 a.m. ET A study published in August found that more than half the world doesn’t consume enough micronutrients essential to health, including calcium, iron and vitamins C and E. Now, California gastroenterologist Saurabh Sethi is sharing five signs that your body needs more nutrition: brittle nails, eyelid twitching, clicking of the joints, premature graying of the hair and bruising easily. Brittle nails Nails are primarily composed of the protein keratin, so it’s crucial to eat plenty of protein to keep nails healthy and strong. The Recommended Dietary Allowance is 0.8 grams of protein per kilogram of body weight — or 0.36 grams per pound. For a 150-pound person, that’s 54 grams of protein daily. More common in women than men, brittle nails can be from frequent hand-washing stripping moisture from the nails, using acetone to remove nail polish, living in cold, dry weather or something as simple as aging. Thyroid disorders and iron deficiency anemia are also possibilities. Foods rich in iron include red meat, poultry, fish, spinach, beans, whole grains and eggs. Eyelid twitching “Twitching in the eyelids or the limbs indicates magnesium deficiency, which is critical for transmitting nerve impulses,” Sethi explained. Myokymia is the scientific term for the orbicularis oculi, a muscle that surrounds the eye and closes the eyelids, contracting involuntarily. The condition has been linked to stress, fatigue, caffeine consumption, an electrolyte imbalance, eye strain from staring at a computer for too long, certain medications and, less commonly, brain and nervous system disorders. Magnesium plays a critical role in muscle function, and while magnesium supplementation is popular, experts encourage consulting with a doctor beforehand to ensure you’re taking the type of magnesium that best suits your needs. Clicking of the joints Cracking, clicking or popping knees are a common occurrence, especially as the body ages. However, Sethi warned “it could be a warning sign of vitamin D3 or calcium deficiency.” Calcium builds and maintains strong bones, while vitamin D helps the body absorb calcium from foods such as milk, sardines and leafy greens.
