A medical professional has highlighted that the presence of white spots on fingernails could indicate a deficiency in essential minerals, a condition often overlooked by many individuals. Dr. Sami, known for sharing health-related content on TikTok under the handle @ask.doctor.s, recently discussed the signs of zinc deficiency in a video post.
In the video, Dr. Sami pointed out that white spots on nails or thinning hair may be indicative of a lack of zinc in the body. Zinc plays a crucial role in the production of keratin and collagen, vital proteins for maintaining healthy hair, skin, and nails. Additionally, zinc is essential for the proper functioning of over 300 enzymes that aid in processes like wound healing, hormonal balance, and immune system support.
Factors such as a diet low in meat and seafood, gastrointestinal issues affecting zinc absorption, excessive sugar or alcohol consumption, and chronic stress can contribute to low zinc levels. To address this deficiency, individuals are advised to incorporate zinc-rich foods like pumpkin seeds, lentils, chickpeas, eggs, nuts, and seafood into their diets. Oysters are particularly highlighted as a top source of zinc. However, caution is advised when considering zinc supplements, with a recommended daily intake not exceeding 25mg unless directed by a healthcare provider to avoid potential side effects.
According to the NHS guidelines, most individuals can obtain sufficient zinc through a balanced daily diet, with recommended daily intake levels of 7mg for women and 9.5mg for men aged 19-64. Food sources rich in zinc include meat, shellfish, dairy products, bread, and cereals.
Healthline notes that white spots on nails can result from various deficiencies, with zinc and calcium deficiencies being common culprits. While a doctor can assess the risk of mineral deficiencies, other potential causes of white spots include allergic reactions or fungal infections, emphasizing the importance of consulting a healthcare professional for any health concerns.
