Tick, Tick, Tick: Allergen in red meat linked to heart disease

Allergen in red meat linked to heart disease

Only in recent years did scientists identify the main allergen in red meat, called galactose-α-1,3-galactose, or alpha-Gal, a type of complex sugar. They also found that a tick -- the Lone Star tick -- sensitizes people to this allergen when it bites them. That is why red meat allergies tend to be more common where these ticks are more prevalent, such as the Southeastern United States, but also extending to other areas, including Long Island, New York.

Researchers have suspected for some time that allergens can trigger certain immunological changes that might be associated with plaque buildup and artery blockages, but no one had identified a specific substance that is responsible for this effect. In the current study, researchers showed for the first time that a specific blood marker for red meat allergy was associated with higher levels of arterial plaque, or fatty deposits on the inner lining of the arteries. The blood marker they identified is a type of antibody (immunoglobulin or IgE) that is specific to the alpha-Gal allergen.
