TikTok Doctor Explains Common Misconception About Shellfish Allergies

A recent TikTok video by Dr. Rubin, MD, a board-certified allergist, has gone viral, shedding light on a common misconception surrounding shellfish allergies. The video opens with a relatable scenario: a girlfriend inadvertently feeds her shellfish-allergic boyfriend a dish containing snails. "It's a common misunderstanding," explains Dr. Rubin in the video. "Many people don't realize that snails are shellfish." Dr. Rubin goes on to explain the crucial distinction between crustacean (shrimp, lobster, crab) and mollusk (snails, mussels, clams, oysters) shellfish allergies. He emphasizes that an allergy to one doesn't automatically mean an allergy to the other, due to differences in their protein structures. The video highlights the protein tropomyosin, found in most shellfish, as a primary allergen. He warns, "Even small traces of protein can cause a reaction, so cross-contamination is a serious concern." The video's informative and engaging style has resonated with viewers, prompting important conversations about food allergies and responsible food handling. Dr. Rubin's expertise adds credibility, making this a valuable educational resource.
