What Are the Symptoms of Celery Allergy?
The symptoms of a celery allergy vary. Some can be reminiscent of a cold or flu, while others affect your stomach and digestive system or even cause breathing difficulties. If you have an allergy to celery, the symptoms include:
- Coughing, sneezing and runny nose
- Shortness of breath
- Nausea and vomiting
- Itchy or swollen eyes
- Stomach pain
- Lightheadedness
- A skin rash
- Swollen lips or throat
In some extreme cases, an allergy can result in anaphylaxis.
In most cases, if you have a celery allergy your symptoms will be worse if you eat raw celery rather than cooked celery.
What Is Food Intolerance?
A food intolerance is caused by your body's inability to process or metabolise a certain type of food, which leads to painful or unpleasant symptoms. This is unlike an allergy, which is your body mistaking the food as a threat, triggering a response from your immune system. Both an intolerance and an allergy can develop at any stage of your life.
How Common Is a Celery Allergy?
Celery allergies and intolerances are surprisingly common, however, because symptoms are far more noticeable after eating it raw, it's only commonly diagnosed in regions where people eat high amounts of raw celery. This includes Switzerland and France, where between 30% and 40% of people with food allergies have a reaction to celery.
So, if you experience any of the above symptoms after eating raw celery, there's every chance it's because you have an allergy or intolerance.
What Should You Do if You Think You Have a Celery Allergy or Intolerance?
If you think you might have a celery intolerance or allergy, you should stop eating celery or food that contains it – even if it's cooked. This isn't just because the symptoms can be uncomfortable, but they can worsen over time.
To find out if you have an intolerance or allergy so you can manage your diet, a food intolerance test or allergy test is a fast and easy way to find out for sure.
How Do You Test for a Celery Allergy or Intolerance?
There are several ways you can find out whether or not you have a celery allergy or intolerance, with varying degrees of accuracy:
- An elimination diet involves you removing food that contains celery from your diet to see whether your symptoms stop.
- You can start a food diary to monitor what you eat and when you experience symptoms to see if there are any patterns.
- You can speak to your doctor or healthcare provider and ask them for advice.
- A food intolerance blood test or food allergy test can help you identify an intolerance or allergy, even if it's not celery.
What Foods Should You Avoid if You Have a Celery Allergy or Intolerance?
If you have an allergy or intolerance to celery or suspect that you do, you'll want to avoid eating any type of food that contains celery, including celeriac and celery seeds. However, other foods to be mindful of that regularly contain celery include:
- Soups
- Sauces
- Salads
- Stews
- Juices
You may also develop an allergy to carrots and spices, and specifically parsley – part of a recognised cross-reactivity pattern sometimes called celery-birch-mugwort-spice syndrome – so this is also something to be mindful of if you have a celery allergy or intolerance.
