Why Meat Glue Isn’t Just Gross — It Could Be Unhealthy Too

Meat glue, or transglutaminase (mTG), has been making headlines for its unusual ability to “glue” pieces of meat together. While it may create a perfect steak or a visually seamless sushi roll, research shows it may also pose health risks, particularly for digestive and autoimmune health.

What is Meat Glue? Transglutaminases (TGs) are natural enzymes in the body that crosslink proteins to stabilize structures like skin, hair, and blood clots. Factor XIII, for example, helps blood clotting, while TGs assist in wound healing and tissue stabilization.

In food production, microbial transglutaminase (mTG) is made from bacteria through fermentation, purified, dried, and added to products to bind proteins together. Unlike naturally occurring TGs in the body, mTG can behave differently once consumed.

Where You’ll Find Meat Glue Many products beyond obvious meat items contain mTG. Here are common examples:

• Processed Meats & Poultry: Formed or restructured hams, sausages, chicken nuggets (learn safe protein practices).

• Dairy Products: Yogurt, cheese, milk, and dairy desserts.

• Seafood: Imitation crab sticks, fish balls, shrimp balls.

• Bakery Goods: Bread, cakes, noodles, and pastries to enhance dough stability.

• Plant-Based & Vegetarian Alternatives: Used to bind vegetable proteins for a meat-like texture (explore healthy meal ideas).

Labeling and Restaurant Use In packaged foods, items containing mTG must appear as “formed” or “reformed” (e.g., “Formed Beef Tenderloin”). But restaurants are not required to disclose if meat glue is used, making it hard to know what you’re consuming.

Potential Health Concerns Studies suggest that eating mTG may contribute to leaky gut, gluten sensitivity, or celiac disease, potentially triggering autoimmune reactions. While more research is ongoing, minimizing intake of processed foods containing mTG is a practical step toward better gut and overall health.

How to Avoid Meat Glue

• Choose high-quality, whole meat: Opt for regenerative, pasture-raised, hormone-free, antibiotic-free, U.S.-sourced meats (family dinner recipes made simple).

• Read labels carefully: Avoid products labeled “formed” or “reformed,” as well as prepackaged meats like chicken nuggets or hot dogs.

• Ask when dining out: Confirm if mTG is used in menu items.

Bottom Line Meat glue may make dishes look perfect, but it’s more than just a visual trick—it’s a hidden ingredient that could impact your health. By focusing on whole, unprocessed foods and reading labels, you can enjoy safer meals and protect your digestive system while still exploring creative, nutritious recipes at home.
