What You'll Learn

Lean meats, fish, and poultry
Lean meats, poultry, and fish are excellent sources of protein, which is essential for building muscle and keeping strong. Nails are made of protein, so consuming protein-rich foods is important for maintaining strong nails. Lean meats, such as beef, lamb, veal, pork, and chicken, are also good sources of other vitamins and minerals that support nail health. For example, beef is rich in vitamins and minerals such as niacin, iron, vitamin B6, vitamin B12, phosphorus, and selenium. Pork is a good source of thiamine (vitamin B), iron, and zinc.
Chicken is another lean meat that is high in protein and provides vitamin B12, choline, zinc, iron, and copper. Organ meats, such as liver, are also excellent for nail health due to their high content of iron and biotin. Fish is also an excellent source of omega-3 fatty acids, which help lubricate and moisturize nails, giving them a shiny appearance. Salmon, halibut, and tuna are particularly good sources of omega-3 fatty acids, as well as zinc, copper, and selenium, which aid in collagen production.
When preparing lean meats, it is recommended to use healthier cooking methods such as baking, broiling, roasting, or stir-frying instead of frying. Choosing lean cuts of meat, such as beef and pork labelled "loin" and "round," can also help reduce fat intake. For ground beef, opt for 90% or 95% lean and trim any excess fat before cooking. Similarly, when preparing poultry, it is best to remove the skin and visible fat.
In addition to lean meats, poultry, and fish, a well-rounded diet should also include a variety of fruits and vegetables, nuts, seeds, and legumes to ensure adequate intake of vitamins and minerals essential for nail health.

Fruits and vegetables
Vitamin C, found in citrus fruits and green vegetables, is an essential nutrient for collagen production, which helps provide strength and integrity to your nails. Fruits such as oranges, strawberries, blueberries, and kiwi are rich sources of vitamin C. Vegetables such as red bell peppers, green peppers, and tomatoes are also excellent sources of this nutrient.
Some vegetables are also rich sources of biotin, which helps reduce nail breakage and promotes healthy nail growth. Cucumbers, cauliflower, and mushrooms are excellent sources of biotin, especially when consumed raw.
Additionally, consuming enough water-rich fruits and vegetables can help with hydration, which is crucial for maintaining healthy nails. Cucumbers, watermelon, and tomatoes are examples of produce that can help you stay hydrated and promote nail health.
In summary, incorporating a variety of fruits and vegetables into your diet provides essential vitamins, minerals, and hydration that support nail health and help prevent and repair brittle nails.

Nuts and seeds
Nuts, such as almonds, cashews, and walnuts, are packed with vitamins and minerals that support nail health. Almonds, for example, are high in vitamin E, which helps protect cells from oxidative damage, and zinc, an essential mineral for nail growth. Cashew nuts provide zinc and walnuts provide omega-3 fatty acids, both of which are crucial for nail strength and health.
Additionally, seeds like chia seeds and flaxseeds are excellent sources of omega-3 fatty acids, which help lubricate and moisturize nails, giving them a shiny appearance and reducing inflammation in the nail bed. Chia seeds also provide calcium and protein, further supporting nail health.
Including a variety of nuts and seeds in your diet can help ensure you're getting the necessary nutrients to support nail health and strength, as well as providing other health benefits.

Eggs
In addition to biotin, eggs also contain vitamin B9 (folate), which is important for nail growth and health. A deficiency in folate can cause a pigment change in your nails and make them rigid and brittle.
The omega-3 fatty acids found in eggs can help lubricate and moisturize your nails, giving them a shiny appearance. These fatty acids may also reduce inflammation in your nail bed, which nourishes and promotes the health of cells that give rise to your nail plate. A lack of omega-3 fatty acids could contribute to dry and brittle nails.
Overall, eggs are a nutrient-rich food that can provide many benefits for nail health. Incorporating them into your diet may help improve the strength and appearance of your nails.
