The food we eat has a huge impact on our health and well-being, and this includes the health of our nails. Dry, cracked, and brittle nails can be a sign of nutritional deficiencies, while strong, shiny nails can indicate a healthy diet and lifestyle. A diet rich in fruits, vegetables, nuts, seeds, and dairy can help replenish vitamins and minerals essential for nail growth. Nails are made of a tough protein called keratin, so it's important to eat enough protein-rich foods such as eggs, lean meats, and beans. Other important nutrients for nail health include biotin, zinc, and iron, which can be found in foods like nuts, leafy greens, and fortified cereals. Hydration is also key to maintaining healthy nails, as water can help to prevent nail splitting and breakage.

What You'll Learn
Lean meats and eggs are a great source of protein and biotin
Eggs are an excellent source of biotin, with the yolks providing 10 micrograms, or approximately 33% of the recommended daily value. They are also a good source of vitamin D, which helps regulate calcium levels, and healthy fats. Half of the protein in eggs comes from the whites, which contain only trace amounts of fat and fewer calories than whole eggs.
Lean meats such as chicken, turkey, beef, and pork are excellent sources of high-quality protein and important nutrients like iron and zinc. Iron is especially important for adolescent girls, pregnant women, and menstruating women. Lean meats also provide collagen, which is crucial to nail health.
To avoid unhealthy saturated fats and sodium, it is important to choose leaner cuts of meat. These include white-fleshed fish, skinless poultry, and cuts of red meat such as loin and round. When preparing lean meats, it is also a good idea to trim off any excess fat.

Nuts and seeds are packed with vitamins and fatty acids
Some nuts and seeds that are particularly beneficial for nail health include almonds, cashews, walnuts, and sunflower seeds. Almonds are high in vitamin E, which helps to protect cells from oxidative damage, and they also contain zinc, which is key to strong nails. Cashews are another nut that provides zinc, while walnuts are a good source of omega-3 fatty acids, which help lubricate your nails and give them a shiny appearance. Sunflower seeds are also excellent for nail health, as they contain magnesium, manganese, copper, vitamin B6, zinc, and vitamin E, all of which contribute to healthy and strong nails.
In addition to these specific types of nuts and seeds, simply adding a variety of nuts and seeds to your diet can help support nail growth and strength. This is because they provide essential fatty acids and vitamins that promote overall health and nourish your body from within, which has a positive impact on your nails.
So, if you're looking to improve your nail health, incorporating a handful of nuts and seeds into your daily diet can be a simple and tasty way to provide your body with the nutrients it needs for stronger, healthier nails.

Leafy greens provide iron, folate, and calcium
Leafy greens such as kale, arugula, watercress, spinach, and collards are rich in iron, folate, and calcium, all of which are essential for maintaining strong nails. Here are the benefits of these nutrients in more detail:
Iron
Iron is crucial for nail health as it is a key component of red blood cells, which are responsible for carrying oxygen throughout the body, including to the nails. Without sufficient iron, oxygen delivery to the nails is compromised, which can lead to nail ridges, concavity, or a spoon-like appearance. Therefore, ensuring adequate iron intake through leafy greens can help prevent these issues and promote healthy nail growth.
Folate
Folate, also known as vitamin B9, is essential for nail growth and overall nail health. It plays a vital role in the formation of red blood cells and the development of new cells. A deficiency in folate can negatively impact nail health, leading to discolouration, rigidity, and brittleness. By consuming leafy greens, you can maintain adequate folate levels, thus supporting the health and appearance of your nails.
Calcium
While calcium is well-known for its importance in bone health, it also plays a role in nail strength. Calcium helps to regulate nail growth and contributes to the hardness and strength of nails. Including calcium-rich leafy greens in your diet ensures an adequate supply of this mineral, promoting stronger and healthier nails over time.
In summary, incorporating leafy greens into your diet is a natural way to boost your intake of iron, folate, and calcium, all of which are essential for maintaining strong and healthy nails. By providing these key nutrients, you can help prevent nail ridges, discolouration, and brittleness, resulting in an improved appearance and overall nail health.

Fatty fish like salmon provide healthy fats and omega-3s
Fatty fish, such as salmon, are excellent sources of healthy fats and omega-3 fatty acids. Omega-3 fatty acids are essential nutrients that offer a multitude of health benefits, including positive impacts on nail health.
Omega-3 fatty acids are a form of polyunsaturated fat, which are healthier alternatives to saturated fats commonly found in meat products. These "healthy fats" are vital to maintaining healthy cells in the body, as they are a crucial component of cell membranes, providing structure and facilitating interactions between cells.
In addition to their role in cell health, omega-3 fatty acids provide energy and support the health of various bodily systems, including the cardiovascular system and the endocrine system. They also play a role in lowering triglyceride levels, which, when too high, can increase the risk of atherosclerosis, heart disease, and stroke.
Fatty fish, such as salmon, mackerel, sardines, and tuna, are excellent sources of these omega-3 fatty acids. Consuming these fish regularly can help support overall health and nail health specifically. The healthy fats and omega-3s found in these fish contribute to shiny, strong nails.
It is important to note that while fish is a good source of protein and omega-3s, it is best to be mindful of potential contaminants. Some types of fish contain high levels of mercury or other environmental contaminants. Therefore, it is recommended to vary your sources of omega-3s and include plant-based sources such as flaxseed and chia seeds, in addition to fatty fish in your diet.

Fruits and vegetables are rich in vitamins and minerals
A diet rich in fruits and vegetables is essential for maintaining healthy nails. Nails are made of a tough protein called keratin, and a diet rich in vitamins and minerals helps support the growth, formation, and strength of new nail cells.
Vitamin E, found in abundance in almonds, is known as the "'beauty vitamin'" because it helps protect cells from oxidative damage. Almonds are also a great source of zinc, which is key to healthy and strong nails. Spinach is another food that is rich in vitamin E and zinc, and it also provides iron, which prevents common signs of nutrient deficiency in fingernails and toenails.
Vitamin B7, also known as biotin, is another important vitamin for nail health. It promotes healthy cell growth and aids in the metabolism of protein-building amino acids, which are essential for nail growth. Eggs, specifically the yolks, are an excellent source of biotin, providing approximately 33% of the recommended daily value. Other biotin-rich foods include cucumbers, cauliflower, mushrooms, and sweet potatoes.
In addition to vitamins, minerals like zinc and iron are crucial for nail health. Lean meats, such as chicken and turkey, are excellent sources of protein and biotin, which are essential for nail strength. Salmon and other fatty fish provide healthy fats and omega-3 fatty acids, which contribute to shiny, strong nails.
A well-rounded diet that includes a variety of fruits and vegetables ensures that the body receives the necessary vitamins and minerals to support nail health and overall well-being.
