🥚 Raw Eggs and Vitamin B7: What You Need to Know! 🥚
Did you know that raw egg whites contain a protein called avidin that can block your body from absorbing vitamin B7 (biotin)? 🤯 Let’s break it down in simple terms!
Biotin is a water-soluble vitamin that keeps your body running smoothly:
💇 Supports healthy hair, skin, and nails
⚡ Helps turn food into energy
🧠 Supports brain and nervous system health
Basically, biotin is like your body’s little energy and beauty helper! 💛
🧐 What is Avidin and Why is It in Eggs?
Avidin is a protein naturally found in raw egg whites. Its main job? To protect the egg by binding to biotin which bacteria need to grow helping keep the egg safe until it’s ready to hatch. 🐣
But here’s the catch: when we eat raw egg whites, avidin also binds to our biotin, stopping it from being absorbed. Over time, eating lots of raw eggs can lower your biotin levels.
🔥 Why Cooking Matters
Good news! Cooking denatures (inactivates) avidin. That means:
🍳 Raw egg whites → Avidin active → Biotin blocked
🍳 Cooked egg whites → Avidin inactive → Biotin absorbed normally
⚠️ Clinical Relevance
Biotin deficiency is rare but can occur with frequent consumption of raw egg whites. Symptoms may include:
Hair thinning or hair loss 💇
Brittle nails 💅
Skin rashes 🌿
Fatigue, mood changes, or tingling sensations 😴
Fun tip: Egg yolks naturally contain biotin, so eating whole cooked eggs gives you all the biotin benefits without the blockage! 🥚💛
