However, it may be possible for a person to have an allergy to both peanuts and sunflower seeds.
The American Academy of Allergy, Asthma and Immunology (AAAAI) notes that cross-reactivity occurs when the proteins in one substance, such as peanuts, are similar to those in another.
The medical team advised the person with a sunflower seed allergy to remove peanuts, sunflower seeds, walnuts, and hazelnuts from their diet and begin immunotherapy treatment.
Anyone with a peanut allergy should speak with an allergist to determine whether it is safe to eat sunflower seeds.

A person can be allergic to sunflower seeds, though it is
A 2022 case study noted that most people who experience severe reactions work in a facility that processes sunflower seeds.
Signs a person is allergic to sunflower seeds
Sunflower seed allergies present with similar symptoms to other food-borne allergies.
According to the
- abdominal cramps
- swelling of the face, tongue, or lips
- tingling or itchy sensation in the mouth
- vomiting or diarrhea
- flushed skin or rash
- swelling of the throat and vocal cords
- coughing or wheezing
- loss of consciousness
- trouble breathing
Symptoms can range from mild to severe and life threatening.
A person experiencing these symptoms for the first time should contact a doctor or allergist to determine what caused their reaction. While it may be the result of sunflower seeds, it is also possible another food caused the reaction.
Allergen cross-contact or cross-contamination occurs when a food product comes into contact with a known allergen during production.
When it comes to cross-contamination of other nuts and seeds, the manufacturer’s only requirement is to ensure they do everything possible to reduce or eliminate the risk of cross-contamination.
The FDA also recommends that manufacturers use voluntary labels indicating possible exposure.
Cross-contamination may occur due to the following:
- the presence of sunflower seeds in a salad bar
- improperly washed machinery
- food preparation in the same area as sunflower seeds
Foods to avoid if allergic to sunflower seeds
A person will need to use caution when selecting food due to the possible use of sunflower seeds or cross-contamination in certain foods.
When eating out, ask the staff whether any items on their menu contain sunflower seeds, and avoid salad bars if seeds are available there.
Other possible sources include:
- baked goods, such as bread
- pre-made salad bags
- snack mixes
Anaphylaxis or anaphylactic shock is a potentially life threatening reaction caused by exposure to an allergen, such as sunflower seeds.
According to the ACAAI, a person should remember S.A.F.E. if someone they know goes into anaphylactic shock. SAFE stands for:
- “S” stands for seek: Seek emergency medical attention by calling 911.
- “A” stands for allergen: Try to determine what allergen caused the reaction.
- “F” stands for follow: Make a follow-up appointment with a specialist.
- “E” stands for epinephrine: Use epinephrine in case of emergencies.
Epinephrine typically comes as a kit. Teaching friends or family how to prepare and use the medication is a good idea, as they may need to inject it into the person’s leg or buttocks.
Once they have injected the epinephrine, they should turn the person onto their side until an ambulance arrives.
Sunflower seed allergies are rare, and those with nut allergies can generally eat sunflower seeds safely.
However, there is a chance of cross-reactivity. As a result, a person with any nut allergy should speak with an allergist before consuming sunflower seeds.
A person should contact an allergist or doctor if they experience symptoms that could indicate a food allergy for the first time. They can help determine the cause of the allergic reaction.
