Hello, I'm a nutrition expert with a strong background in biochemistry. Biotin, also known as vitamin H or vitamin B7, is a water-soluble vitamin that plays a crucial role in various metabolic processes within the body. It's essential for the synthesis of fatty acids, amino acids, and glucose, and it's also vital for the health of our skin, hair, and nails. Despite its importance, biotin deficiency is relatively rare because our bodies can produce it in the gut, and it's also found in a variety of foods. However, there are several causes that can lead to biotin deficiency:
1. Inadequate Dietary Intake: A diet lacking in biotin-rich foods can lead to deficiency. Foods such as eggs, dairy products, nuts, and certain vegetables and fruits are high in biotin. Vegetarians and vegans, who may not consume enough animal products, are at a higher risk of developing a biotin deficiency.
2. Gastrointestinal Disorders: Conditions that affect the gastrointestinal tract, such as Crohn's disease, celiac disease, and inflammatory bowel disease, can interfere with the absorption of biotin, leading to a deficiency.
3. Long-term Use of Certain Medications: Some medications, particularly those used to treat seizures like anticonvulsants, can increase the excretion of biotin and lead to a deficiency.
4. Excessive Consumption of Raw Egg Whites: As you mentioned, raw egg whites contain a protein called avidin, which has a strong affinity for biotin. This can lead to biotin deficiency if consumed in large amounts over a long period. Cooking egg whites reduces the bioavailability of avidin, thus mitigating this risk.
5. Genetic Disorders: Certain genetic disorders can affect the body's ability to utilize biotin effectively, leading to a deficiency.
6. Pregnancy: The increased metabolic demands during pregnancy can lead to an increased need for biotin. If dietary intake is not increased accordingly, it may result in deficiency.
7.
Long-term Parenteral Nutrition: Individuals who receive long-term intravenous nutrition without biotin supplementation can develop a deficiency.
8.
Excessive Alcohol Consumption: Chronic alcohol abuse can lead to malnutrition and deficiencies in various nutrients, including biotin.
9.
Strenuous Physical Activity: While exercise is generally beneficial, excessive physical activity without proper nutrition can deplete the body's stores of certain nutrients, including biotin.
10.
Age-Related Factors: Older adults may be at a higher risk of developing biotin deficiency due to decreased absorption and increased excretion.
It's important to note that while biotin deficiency can have serious health implications, it can be prevented and treated with a balanced diet and, if necessary, supplementation. If you suspect a biotin deficiency, it's crucial to consult with a healthcare provider for proper diagnosis and treatment.

However, deficiencies can be caused by consuming raw egg whites over a period of months to years. Egg whites contain high levels of avidin, a protein that binds biotin strongly. When cooked, avidin is partially denatured and binding to biotin is reduced.
