Brussel Sprouts Allergy – Symptoms and Treatment


Brussel sprouts are vegetables belonging to the family of cabbage. They are rich sources of sulforaphane and indole-3-carbinol known for anti-cancer and DNA repair properties. But, brussel sprouts allergy is reported by individuals whose body is sensitive to these otherwise beneficial natural chemicals. This article tries to learn about the symptoms and treatment of this brussel sprouts allergy.

Scientifically no allergen of this plant in pure form has been yet verified. Lipid transfer protein or LTP has been found in Broccoli which is a close family member of Brussel but it is not yet confirmed if it is present in it. However, people do complain about this allergy and we have collected this data from the web especially forums which might give insight to people who develop symptoms out of eating it.

Brussel Sprouts Allergy Symptoms

Below are some of the primary symptoms of Brussel Sprouts Allergy which is very similar to other forms of food allergy:

  • Itching
  • Swelling of face, arms and feet
  • Skin rash
  • Difficulty in breathing
  • Skin color changes
  • Runny rose
  • Headaches
  • Stomach pain
  • Drop in blood pressure
  • Dizziness
  • Allergic reactions spreading all over the body rapidly

Awareness of these symptoms can help in early consultation with the doctor. A type of blood test known as radioallergosorbent or RAST test can identify the chemical behind the allergy or the allergen. Later, a skin patch test can confirm the condition.

Brussel Sprouts Allergy Treatment

The immune system is the natural protection mechanism of the body. A protein called IgE found in the blood is part of this system. Its responsibility is to deal with the allergens and protect the body from them.

In some individuals, the immune system mistakenly identifies the beneficial chemicals in a substance to be threat to the body. These chemicals are targeted by IgE as part of the defensive response. Such over-response initiates certain undesirable reactions in the body known as allergy.

Unfortunately, there is no cure for food allergy. The treatment aims at keeping the symptoms of the allergy under check. Blood test and skin patch test can find the probable allergens and confirm the condition by verifying the signs.

Prevention is better than cure. So the first step to get rid of this allergy is to stay away from brussel sprouts. This simple step can control the mild signs. However, moderate to severe symptoms of allergy from brussel sprouts may require antihistamine drugs.



  1. Grilled Brussel Sprout Lover on

    I have an allergic reaction that used to be very bad when I was younger. My Mom forced me to eat a brussel sprout even though I said the smell was making me very nauseous. After projectile vomiting across the table, she believed me. I can eat grilled brussel sprouts now with no problem and actually love them. I still can barely get down boiled brussel sprouts, I tried recently.

  2. I used to throw up brussel sprouts when I was a child I cannot hold them down the boiled ones my son just made him the other day he tried them on in the skillet and I still throw them up it doesn’t matter I don’t know why I throw up I tried him and I try to keep him down for two days now I’ve been sick

  3. I get dizzy and my head throbs keeping me awake at night. I have just realized that this must come from eating brussel sprouts which I roasted in the oven. Also I feel very congested in my nasal passages and head and it carries over for a day or so. I finally realized it must be the brussel sprouts!

  4. This is so funny. I love BS’s. I learned that by boiling them for a few minutes in water with fresh lemon juice, I could get rid of the bitterness that makes them offensive to many folks. I prefer roasting them after the boiling ‘cure’. But I just noticed that they make me dizzy. 🙂 That’s why I googled this. Odd.
