Updated on April 28, 2024

You’re at a backyard barbecue, the tantalising aroma of grilled meat wafting through the air. You reach for that mouthwatering burger, only to discover later that it triggers an unwelcome guest—alpha-gal allergy. 

Living with an alpha-gal allergy can sometimes feel akin to trekking through a culinary labyrinth. Having to pore over food labels persistently like an obsessive detective and bid farewell to your cherished meals can be somewhat overwhelming! In this article, we’re about to unfold exhaustive insights on the foods to avoid when grappling with this allergy. Are you prepared for the journey? Let’s hop right in!

What is Alpha-gal Allergy?

Alpha-gal allergy goes by many names. You might hear it called alpha-gal syndrome, AGS for short, or even red meat allergy and tick bite meat allergy. Alpha-gal allergy is not your typical food allergy. It’s not about peanuts or shellfish; it’s a unique food allergy where the immune system reacts negatively to a sugar molecule called galactose-α-1,3-galactose.

Connection to Lone Star Tick Bites

Here’s where it gets interesting: blame it on the Lone Star tick! When this tiny, seemingly harmless tick bites you, it injects a substance into your bloodstream that triggers your immune system to develop Immunoglobulin E (IgE) antibodies against alpha-gal. So, it’s not the meat itself that causes the problem; it’s the tick that has become an unwitting accomplice in the rise of alpha-gal allergy cases. So, next time you find yourself in a tick-infested area, maybe skip the steak dinner – your immune system will thank you!

What are the Symptoms of Alpha-gal Allergy?

So, you savour a delicious steak during a summer barbecue, and everything seems fine. But a few hours later, or even in the dead of night, your body decides it’s time to protest. Symptoms like itching, stomach cramps, hives, and swelling can surprise you when you least expect it. Some might develop severe allergic reactions and experience a severe drop in blood pressure, which is sometimes fatal. This condition called anaphylaxis happens in many cases—about 60 per cent!

It’s weird because these symptoms often show many hours after eating, making it a challenge to identify and manage, unlike other food allergies that strike almost immediately. So, if you think you have this type of allergy, seek your doctor’s help immediately!

Where is Alpha-gal Allergy Prevalent?

Alpha-gal allergy has been most commonly reported in the southeastern United States, where the Lone Star tick (Amblyomma Americanum) is prevalent. States like Tennessee, North Carolina, Virginia, and parts of the Midwest have historically shown 32% higher alpha-gal allergy cases.

However, it’s important to note that the distribution of alpha-Gal allergy is evolving, and cases have been reported in other regions as well. The Lone Star tick has been expanding its range. Climate changes and ecological shifts may contribute to the spread of both the Lone Star tick and, consequently, cases of alpha-gal allergy.

Which Age Group Does this Allergy Target?

Alpha-gal allergy can affect individuals of various age groups, including children, but it often presents itself in adults. The reason for this is related to the exposure to Lone Star tick bites, which is a significant factor in the development of alpha-gal allergy.

Lone Star ticks are commonly found in outdoor environments, and individuals who spend time in wooded or grassy areas where these ticks are prevalent are at a higher risk of encountering them. Outdoor activities like camping, hiking, or gardening may increase the likelihood of tick bites.

Foods to Avoid with Alpha-gal Allergy


So, you’ve found yourself in the alpha-gal allergy club, and now you’re wondering, “What’s on the no-no list?” Since alpha-gal is the culprit behind the allergy, let’s check out where this seemingly harmless sugar likes to hide. Alpha-gal is found in non-primate mammal meats like cows, pigs, and lamb, some dairy products, gelatine-containing foods, and some processed foods.

1. The Meaty Hit List: Specific Meats to Dodge

Beef, pork, lamb, and their relatives—these are the usual suspects. Say goodbye to your beloved steak dinners, burgers, ribs, and bacon-filled breakfasts. Goats, venison, rabbits, horses, and marine mammal meats are also on the ‘do not eat’ list. Watch out for terms like gelatine and collagen in ingredient lists to identify hidden meat derivatives and meat-based ingredients.

2. Ditch the Lard and Mammalian Derived Fats

Not just meats, but lard is also an unexpected source of alpha-gal! Pig fat can cause allergic reactions in people with alpha-gal allergy. You might find lard in biscuits or refried beans. It’s also used to thicken gravy and sauces. Be careful when buying baked goods and side dishes; they might also have lard in them! 

3. Dairy Dilemmas: The Stealthy Alpha-Gal in Dairy

Alpha-gal might just be the party crasher in your dairy delight. Keep an eye out for certain cheeses, milkshakes, and ice creams. But fear not! A world of dairy-free treats is waiting for you—almond milk lattes and coconut ice cream; here you come! These substitutes let you enjoy creamy goodness without triggering that alpha-gal allergy alarm.

4. Gelatine-Containing Squishes: Unmasking Alpha-gal in Disguise

Alpha-gal might be wearing a gelatine disguise, lurking in gummy candies, marshmallows, and even some medications. So, stay vigilant. Swap gelatine for plant-based alternatives like agar-agar or pectin. Your sweet tooth won’t even notice the difference, and alpha-gal allergy can take a backseat.

5. Spot the Alpha-gal in Processed Foods

Processed foods are alpha-gal’s secret hideout. Soups, sauces, and snacks deserve a scrutinised second look at those ingredient labels. Opt for snacks and meals that proudly declare their alpha-gal-free status. From sauces to soups, a whole world of allergy-friendly options is waiting for you. Eating safe doesn’t mean sacrificing flavour—it’s just a matter of knowing where to look.

Coping Strategies and Alternatives for Alpha-gal Allergy

We have some strategies and alternatives to outsmart your alpha-gal allergy and make your journey a bit more enjoyable.

1. Explore Alternative Protein Sources

Miss the protein punch from red meat? Alpha-gal allergy might have removed the red meat protein source, but it opened the door to diverse protein alternatives. Here are some of your options:

  • Choose nonmeat alternatives like chicken, turkey, emu, duck, goose, and quail, as they do not trigger alpha-gal allergies.
  • Seafood, like shrimps, fish, and crabs—there’s so much variety here.
  • Soy is full of protein and can replace meat in most dishes.
  • Tofu and tempeh offer not just protein but delicious flavours. 
  • Nuts such as almonds, cashews, and peanuts are good for snacking. They’re high in proteins and healthy fats.
  • Seeds like sunflowers or pumpkins are also packed with protein.
  • Pulses like lentils, chickpeas, and beans are rich in proteins and can be used as main meals instead of red meats.

2. Use Butter Substitutes

We are aware that living with alpha-gal allergy is no small feat, and you’ll need to make some significant changes in your kitchen. One of them is finding butter substitutes, and here are some of your options:

  • Vegetable shortening is the top pick. It works well in most recipes.
  • Dairy-free butter is another good choice. It tastes like real butter!
  • Vegan options are great for severe allergies. These use plant-based ingredients.
  • Coconut oil acts just like butter in cooking and baking.
  • Plant-based spreads are the new favourite on bread and crackers.
  • Margarine does work as well.
  • Nut-based butter offers unique flavours for toast and sandwiches.
  • Olive oil can be used as a rich and healthy alternative.

3. Become the Chef of Your Kitchen and Modify Your Recipes

Become the maestro of your kitchen. Swap alpha-gal-laden ingredients with allergy-friendly alternatives. Turn a traditional lasagna into a plant-based masterpiece or transform a classic stir-fry into a friendly protein-packed delight. Cooking with alpha-gal allergy can be challenging, but there are still ways to enjoy mouthwatering meals. Here are some cooking tips to help you navigate your dietary restrictions:

  • Household items: Certain cleaning products and detergents may contain ingredients derived from mammals that could also have alpha-gal.
  • Vaccines: Some vaccines can be produced using mammalian cells or products, which may contain traces of alpha-gal.

Determining Your Tolerance for Alpha-gal

When it comes to alpha-gal allergy, the risk is variable. Each person’s tolerance for alpha-gal can be different. Some people may have mild reactions, while others may experience more severe symptoms. It’s important to remember that avoiding tick bites and mammalian meats is crucial in managing this condition. 

Managing Alpha-gal Allergy 


Managing your alpha-gal allergy can be a personal journey, as everyone’s tolerance level to alpha-gal varies. Working closely with your healthcare provider is vital to determine which foods and products you need to eliminate from your diet. They can guide you by creating a personalised nutrition plan that meets your specific needs. By customising your allergen management strategies, you can take control of your allergy and live a healthier life.

Managing Alpha-gal Allergy in Restaurants and Social Settings

When dining out with an alpha-gal allergy, it can be challenging to convey your dietary needs. However, restaurant cards can help make this communication easier. Here are some ways restaurant cards can support individuals with alpha-gal allergy:

  • Communicate your allergy: Restaurant cards clearly and concisely communicate your alpha-gal allergy to restaurant staff, chefs, and managers.
  • Specify foods to avoid: These cards outline the specific foods that must be avoided due to the alpha-gal allergy. This ensures the kitchen staff understand which ingredients should not be included in your meal.
  • Overcome language barriers: Restaurant cards are especially helpful for those travelling or dining in foreign countries where language may be a barrier. They can be printed in multiple languages, allowing you to communicate your dietary needs effectively despite any language differences.
  • Visual cue for kitchen staff: A physical card serves as a visual cue for the kitchen staff, helping them remember and prioritise your allergy when preparing meals.

Allergy Testing and Healthcare Support

If you suspect you have alpha-gal syndrome, it’s essential to:

  • Seek allergy testing: Getting tested for alpha-gal syndrome can help confirm whether or not you have the allergy. This will provide valuable information for your healthcare provider to develop a treatment plan and dietary guidelines tailored to your needs.
  • Seek healthcare support: Managing alpha-gal syndrome requires professional guidance and support from healthcare providers. They can provide you with the necessary medications, such as antihistamines or epinephrine auto-injectors, to treat allergic reactions. They can also monitor your condition and help educate you about potential triggers and ways to prevent allergic reactions. As alpha-gal syndrome is a chronic condition, ongoing healthcare support is crucial for long-term management. Regular check-ups with your healthcare provider can help track changes in your symptoms or tolerance levels over time.

Tips for Avoiding Tick Bites and Preventing Alpha-gal Allergy

Tick bite prevention is critical in avoiding alpha-gal syndrome. Here are some tips to help you prevent tick bites:

  • Wear long-sleeved shirts and lengthy pants outdoors, especially in wooded areas.
  • Use insect repellents that contain picaridin or DEET on exposed skin.
  • Treat your outdoor clothing and gear with permethrin, an insecticide that repels ticks.
  • Stay on trails, and don’t walk through tall grass where ticks may be present.
  • Check yourself for ticks on your body after you spend time outdoors. 
  • Remove any attached tick promptly by using tweezers to grasp it and pull it straight up with steady pressure.
