Keratin is a protein that is found in many parts of the body, including the skin, hair, and nails. It is not a nutrient that is found in food, so no food contains keratin.
Keratin is produced by the body, and the amount of keratin produced can be influenced by factors such as genetics, age, and diet.
While food does not directly contain keratin, some foods contain nutrients that are important for the production of keratin, such as:
- Protein: Protein is essential for the production of all proteins, including keratin. Good sources of protein include meat, poultry, fish, eggs, beans, lentils, and tofu.
- Biotin: Biotin is a B vitamin that is important for hair and nail growth. Good sources of biotin include eggs, nuts, and seeds.
- Zinc: Zinc is a mineral that is important for cell growth and repair. Good sources of zinc include oysters, red meat, and nuts.
- Vitamin A: Vitamin A is important for the health of skin, hair, and nails. Good sources of vitamin A include sweet potatoes, carrots, and spinach.
By consuming a diet that is rich in these nutrients, you can support the body's natural production of keratin.
