According to the Centers for Disease Control and Prevention, approximately one in every 20,000 raw eggs may contain Salmonella bacteria. This statistic causes many to wonder: are liquid egg whites safe to eat?

Did you know that a protein in raw egg whites can prevent your body from absorbing a key vitamin? It's true; a compound called avidin binds tightly to biotin in raw eggs, making it unavailable to your body.

According to the National Institutes of Health, biotin deficiency is relatively uncommon in healthy people, but a number of factors can significantly interfere with the body's ability to absorb this vital nutrient. Understanding what inhibits the absorption of biotin is essential for those at risk of deficiency, ensuring optimal intake and preventing health complications.

In the early 1900s, researchers observed that feeding large amounts of raw egg whites to rats produced a toxic syndrome characterized by severe dermatitis and hair loss. The subsequent discovery of biotin, and its tight binding by avidin in the raw egg whites, revealed the reason for this condition. So, does avidin block the absorption of biotin? The answer is a clear yes, but only under specific circumstances that are easily avoidable.

In the early 1900s, scientists discovered that feeding raw egg whites to animals caused a condition known as "egg-white injury," eventually leading to the identification of avidin, the protein that decreases absorption of biotin. This insight highlights a crucial interaction between food and nutrient bioavailability.

While many water-soluble vitamins are notoriously fragile when exposed to heat, biotin, also known as vitamin B7, displays a surprising degree of thermal stability. Understanding the real science behind biotin's resistance to heat is crucial for preserving its benefits when preparing biotin-rich foods.

According to the FDA, approximately one in 20,000 eggs is contaminated with Salmonella, presenting a significant food safety risk. This fact alone raises a crucial question for many health enthusiasts: are eggs healthier when raw, or does the cooking process offer superior benefits?

According to the University of Rochester Medical Center, biotin is not destroyed by cooking. This fact is particularly relevant for those who want to maximize their nutritional intake, as some water-soluble vitamins are notoriously vulnerable to high temperatures. So, is biotin sensitive to heat, and what does this mean for your diet?

While a large, raw egg contains about 6.3 grams of protein, a cooked egg of the same size holds a very similar amount, averaging around 6.4 grams. The key distinction, however, lies not in the total quantity, but in how effectively your body can actually use the protein once consumed, which directly addresses the question: does a raw egg have the same amount of protein as a cooked egg?

Marginal biotin deficiency affects a significant proportion of pregnant and lactating women, indicating that optimal absorption is not always guaranteed. Understanding what hinders biotin absorption is crucial for anyone looking to maintain sufficient levels of this vital nutrient.
