5 FOODS TO EAT FOR HEALTHY HAIR AND NAILS
By Sally Shi-po POON (Registered Dietitian)
Shiny hair and strong nails are hallmarks of beauty. The solution could be in your kitchen! Here are 5 beauty foods that dietitian Sally Poon recommends to eat for healthy hair and nails.
Eggs deliver all the amino acids our body needs to build protein. Protein is found throughout the body; and both hair and nails are made from a protein called keratin. Therefore, eating adequate amounts of protein daily plays a crucial role in healthy hair and nails. An extra-large egg contains 7 grams of protein, which can be considered as 1 ounce-equivalent from meat, fish and poultry. In general, adults are advised to consume 5 to 8 ounces of meat, poultry, fish, egg and alternatives daily.
Eggs also contain biotin – a key nutrient for maintaining healthy hair and nails. Eggs should be eaten cooked as avidin found in raw egg whites can interfere with biotin absorption. Cooking denatures avidin, making biotin absorbs efficiently in the gut. Other foods that contain the most biotin include beef liver, salmon, tuna, pork, sunflower seeds, almonds, and sweet potatoes.
- Pine nuts
Pine nuts are a good source of copper – one of the key nutrients involved in collagen formation. Collagen is found in our skin, hair and nails. Copper also works with iron to help the body produce red blood cells. Other dietary sources of copper include oysters, organ meats, whole grains, beans, and yeast.
Oysters are an excellent source of protein and zinc. Zinc is found in cells throughout the body. It plays a role in immune function, protein synthesis, cell growth, and wound healing. Zinc deficiencies have been linked with hair loss and Beau’s lines (indentations that run across the nails). Other dietary sources of zinc include beef, lamb, pork, poultry, crab, lobster, beans, nuts, fortified breakfast cereals, and dairy products.
Seaweed is the best food source of iodine. Iodine helps maintain normal thyroid function and its deficiency can lead to thyroid disorders as a cause of hair loss. Other food sources of iodine include fish, seafood, dairy products, eggs and iodized salt.
Beef is an excellent source of iron – one of the key nutrients involved in blood formation in our body. Iron deficiency anaemia has been linked with hair loss and appearance of spoon nails (soft nails that look scooped out). Other food sources of iron include lean meat, poultry, liver, oysters, salmon, tuna, dried beans, dried fruits, egg yolks, fortified cereals, wholegrains, and spinach.
Our body absorbs plant-based iron better when you eat it with meat, fish, or poultry. Foods rich in vitamin C, such as guavas, kiwifruits, oranges, strawberries, bell peppers, and tomatoes, also increase iron absorption.
