Most of us worry about Lyme disease or Rocky Mountain spotted fever when getting a tick bite. But different species of ticks can transmit a variety of diseases—and at least one very unusual ailment, scientists have learned: an allergy to red meat.
Why can’t you eat red meat with Lyme disease?
The bite transmits a sugar molecule called alpha-gal into the person’s body. In some people, this triggers an immune system reaction that later produces mild to severe allergic reactions to red meat, such as beef, pork or lamb, or other mammal products.
How long after a tick bite are you allergic to meat?
Symptoms commonly appear 3-6 hours after eating meat or exposure to products containing alpha-gal (for example, gelatin-coated medications). AGS reactions can be different from person-to-person and can range from mild to severe or even life-threatening.
Can being bit by a tick make you allergic to meat?
Researchers have identified cases of rare red meat allergy linked to tick bites. Lone Star ticks range from the Southeast through the Eastern United States and bites from the arachnids are known to cause a rare allergy to galactose-α-1,3-galactose (α-gal), a type of sugar found in beef, pork, lamb, and other red meats.
What are the symptoms of a meat allergy?
Alpha-gal and Red Meat Allergy
- Hives and itching.
- Swelling of your lips, face or eyelids.
- Shortness of breath, cough or wheezing.
- Abdominal pain, nausea, diarrhea or vomiting.
Why do I get sick after eating red meat?
Weakened immune system
When your body doesn’t digest meat properly, you might get sick more often than usual. Your immune system can be affected because of the natural sugar (called Neu5Gc) found in red meat, and it is very hard for our bodies to digest.
What can you not eat with Lyme disease?
The ‘red flag’ foods that feed inflammation and Lyme are gluten, dairy, and sugar. Many of us have experimented with various gluten-free, dairy-free or other diets.
What foods to avoid if you are allergic to alpha gal?
Once alpha-gal allergy is diagnosed, all mammalian meats and by-products should be avoided. This includes, beef, pork, lamb, venison, mutton, goat, and bison, plus any food that contains red meat extracts. Some individuals with alpha-gal allergy must also avoid dairy products made from cow’s, sheep’s or goat’s milk.
Can you be allergic to sperm?
In rare cases, people have been known to have allergic reactions to proteins in their partner’s semen (semen allergy). Semen allergy isn’t a direct cause of infertility. Signs and symptoms of semen allergy include redness, burning and swelling where the semen has contacted the skin, usually in the outer genital area.
Can alpha gal allergy go away?
Symptoms of alpha-gal syndrome may lessen or even disappear over time if you don’t get any more bites from ticks that carry alpha-gal. Some people with this condition have been able to eat red meat and other mammal products again after one to two years without additional bites.
Is Alpha Gal an autoimmune disease?
As a result of autoimmune responses, some people become allergic to alpha-gal. People with this allergy may experience mild discomfort after eating meat, or they may have a dangerous reaction that leaves them unable to breathe. The spectrum of reactions to alpha-gal varies.
What foods contain alpha gal?
Foods made from high fat content milk, such as ice cream and whole cream, also may contain alpha-gal. Plasma expanders used in Europe and other parts of the world, such as polygeline (Haemaccel) and succinylated gelatin (Gelofusine) are also potential, albeit unlikely, sources of alpha-gal.
Can you eat chicken with alpha gal allergy?
Commins: Initially, we ask people to strictly avoid red meat—beef, pork, lamb, this would include venison, bison, buffalo—anything essentially that has hooves and walks on four legs, we ask them to avoid. They can certainly eat chicken, turkey and fish, but we often leave dairy in their diet if they can tolerate it.
Do eggs have alpha gal?
A person diagnosed with an alpha-gal allergy will probably have to change their diet and be careful when they eat out. Seafood, poultry, and eggs are acceptable protein choices for those with alpha-gal allergies. Many people can also tolerate dairy products.
