Salicylate Intolerance: The Complete Guide + List of Foods


[Last updated 10th June, 2019]

Salicylate intolerance is not fully understood by scientists.

The condition is often misdiagnosed, and there’s a variety of possible treatments.

Some salicylates are relatively easy to stay away from, but others are nearly impossible to avoid.

This article looks at the evidence-based ways to treat salicylate intolerance. 

What Are Salicylates?

What Are SalicylatesSalicylates is the general term for chemicals that have salicylic acid as their base.

Salicylic acid is a naturally occurring organic acid found in a variety of plants. These plants produce it as part of their defense system against diseases, insects, bacteria and environmental stress.

Salicylic acid is used as an ingredient in synthetic salicylates and a variety of other products. Aspirin, for example, is made by combining salicylic acid with a chemical called acetic anhydride.

Summary: Salicylates are a group of chemicals that form part of a plant’s natural defense system. They are also used as ingredients in a variety of products.

What Is Salicylate Intolerance?

Most tolerate regular amounts of salicylates without any issues.

However, in some people even a small dose can cause problems. This is called salicylate intolerance or salicylate sensitivity.

What Is Salicylate Intolerance

The percentage of people suffering from salicylate intolerance is unknown but it appears to occur more often in adults than children (1).

The only type of salicylate that has clearly been shown to cause negative reactions in those with salicylate intolerance is acetyl salicylate (in aspirin) (2).

The amount of salicylates in regular aspirin is typically 325 mg. Extra-strength aspirin or arthritis pain relievers can contain 600–650 mg.

In comparison, daily intake of salicylates from food is estimated to be 10–200 mg on average (3).

While foods containing salicylates may be able to cause similar reactions to aspirin, there’s no current research to confirm this. And since pain relievers are often taken multiple times a day, the potential amount of salicylates from medication can vastly outweigh those from foods.

As with other intolerances, such as histamine intolerance, the amount of salicylates consumed probably determines whether symptoms occur. Most people with sensitivities can tolerate at least a small amount.

Summary: Salicylates do not cause problems for most people, however those who are sensitive will react to small amounts. Aspirin is by far the largest source for humans.

Signs and Symptoms of Salicylate Intolerance

Signs and Symptoms of Salicylate IntoleranceTypical signs and symptoms of salicylate intolerance include (1):

  • Sinus inflammation and infection
  • Polyps (small, non-cancerous growths) in the nasal and sinus passages
  • Asthma
  • Hives
  • Fever
  • Tissue swelling
  • Inflammation of large intestine, which can cause abdominal pain and discomfort
  • Diarrhea.

As symptoms of salicylate intolerance can appear very similar to an allergy (hives and sinus problems, for example), it is often misdiagnosed. In fact, for some people salicylates only cause symptoms when they are experiencing allergies, making it even harder to separate the two (5).

However, unlike an allergy, salicylate intolerance doesn’t involve the immune system.

Salicylate intolerance is also more common among adults with asthma. It’s been estimated that 2–23% of asthmatics are sensitive to aspirin (4).

However, the mechanism by which aspirin and other NSAID medications containing salicylates affect asthma is thought to be due to the inhibition of COX-1 enzyme and not the salicylates themselves.

Summary: Symptoms of salicylate intolerance often include asthma, hives, sinus problems and nasal polyps. These symptoms are sometimes mistaken for allergies.

Food Sources of Salicylates

Food Sources of SalicylatesMany foods naturally contain salicylic acid.

Reported levels of salicylates in foods differ somewhat, likely due to differing methods of analysis and the growing conditions and varieties of plants tested.

In general, the highest amounts of salicylates are found in fruits, vegetables and spices. Cereals, meat, fish and dairy products contain very little or none (3).

Based on weight, herbs and spices have the highest concentrations of salicylic acid. Curry powder, for example, has been reported to have 218 mg per 100 grams of powder (3).

For comparison, raspberries are reported to have 4.4 mg per 100 grams and they are considered a high salicylate food.

The following list the salicylate content of different food categories from low to high (2, 3, 13):

Other Sources of Salicylates

Many health and beauty products and household cleaners also contain salicylates.

They serve a variety of functions in these products including as fragrances, preservatives, exfoliants, conditioners, and anti-dandruff and anti-acne agents.

Summary: Salicylates are found in many foods, medicines, cosmetics and household cleaners. Foods with the highest amounts include spices, fruits and vegetables.

Does Salicylate Intolerance Cause Other Digestive Diseases?

Does Salicylate Intolerance Cause Other Digestive DiseasesSome data suggests that salicylate intolerance may cause other diseases of the digestive tract, including inflammatory bowel disease and food allergies.

One group of researchers suggested that 2–7% of patients with these conditions may also have salicylate intolerance (1).

In that study, patients with ulcerative colitis or food allergies were 3–5% more likely than those with Crohn’s disease to be salicylate intolerant.

The authors suggested that the possibility of salicylate intolerance should be considered among all patients with ulcerative colitis or food allergies.

Summary: Salicylate intolerance may be more common in those with food allergies or Ulcerative Colitis. However, scientists are unsure exactly how the conditions are related.

Treatments For Salicylate Intolerance

Treatments For Salicylate IntoleranceAvoiding aspirin and other salicylate-containing medications is the first line of defense for those with salicylate intolerance.

Switching to cosmetics and cleaners without salicylates may also be helpful.

In some cases, treatment with steroids, other medications or even surgery to remove respiratory growths may be necessary (5).

Desensitization is another treatment sometimes used. The patient is given daily doses of acetyl salicylate, and the dose is slowly increased over time. In about 80% of cases, improvements in ease of breathing, sense of smell and freedom from recurring polyps are observed (6).

Desensitization should only be undertaken with a physician’s care. The first phase is often done in a hospital, since adverse reactions, including asthma, can occur (5).

Summary: Avoidance of aspirin and other salicylate-containing products may be necessary for those with a salicylate intolerance. In some cases, medications, surgery or desensitization treatment may be suggested by a physician.

Is a Low-Salicylate Diet Necessary?

Is a Low-Salicylate Diet NecessaryFor adults who have found no other treatments helpful, a low-salicylate diet is worth consideration (9).

However, there is currently no scientific proof this form of elimination diet is of any benefit (10, 11). In fact, anecdotal reports indicate a low-FODMAP diet may be the better alternative, which is scientifically shown to help treat food intolerance.

Unfortunately, elimination diets are not really appropriate for children.

One study of 74 children put on an elimination diet for salicylates found that almost half experienced harmful side effects. This included nutrient deficiencies, food aversions and eating disorders (7).

Nutrient deficiencies during childhood can have long-lasting impacts on health and development (8). For these reasons a low-salicylate diet (or other elimination diet) should be the last line of treatment for children.

Summary: In severe cases, adults may trial a salicylate-restricted diet (followed by reintroduction) or a low-FODMAP diet. Elimination diets are not usually recommended for children.

A Low-Salicylate Diet Plan

A low salicylate diet planAdults with a high sensitivity to aspirin who have found no relief from other treatments may wish to try a low-salicylate diet.

Important tips to keep in mind:

  • Only foods with the highest levels of salicylates should be avoided (see list above).
  • Restrict high-salicylate foods for a maximum of 4 weeks.
  • Slowly reintroduce high-salicylate foods, noting any symptoms that occurs in a food and symptom diary.
  • Be sure to include plenty of fruits and vegetables that are not on the high-salicylate list.

Here is an example of a realistic 3-day low-salicylate diet plan:

Day 1

Breakfast: Cereal with milk, banana

Lunch: Salad with shredded cabbage, grilled chicken breast, shredded cheese and dressing; peeled green apple

Dinner: Baked fish with brown rice and roasted Brussels sprouts

Snacks: Yogurt, peeled pear

Drinks: Water, milk

Day 2

Breakfast: Yogurt with granola and sliced, peeled pear

Lunch: Sandwich with wholegrain bread, sliced turkey breast, iceberg lettuce and cheese

Dinner: Breakfast-style burritos with wholegrain tortillas, scrambled eggs, black beans, cheese and shredded cabbage

Snacks: Celery sticks with hummus, string cheese, peeled green apple

Drinks: Water, milk

Day 3

Breakfast: Oatmeal with chopped cashews

Lunch: Tuna sandwich on wholegrain bread, lentil soup, peeled pear

Dinner: Baked chicken with mashed (white) potatoes and green beans

Snacks: Yogurt, banana, wholegrain crackers with sliced cheese.

Drinks: Water, milk

If you feel a low-salicylate diet plan may help you, see a registered dietitian to help you plan an appropriate balanced diet.

Fish Oil For Salicylate Intolerance

Fish Oil For Salicylate IntoleranceLooking at supplements, only fish oil may has been examined for salicylate intolerance.

One small study reported on three patients with extreme intolerance to salicylates, including severe hives and asthma.

After taking fish oil for 6–8 weeks, all three experienced complete or nearly complete improvement of their symptoms. The authors suggested that daily supplementation with 10 grams of fish oil rich in omega-3 fatty acids appears to be a safe and effective treatment for salicylate intolerance (12).

Unfortunately, due to the study size and quality we can’t make any recommendations until more research is complete. Additionally, 10 grams of fish oil per day is incredibly high and should be done under medical supervision.

Summary: Early evidence suggests 10 grams per day fish oil supplementation may help treat salicylate intolerance. However, this is based on a weak study.

We Have Much More To Learn

Salicylate intolerance is a poorly understood condition.

Treatment can be difficult as it shares symptoms with many allergies and other food intolerances.

Salicylates are also present in a wide variety of foods, medicines, cosmetics and other products, making them difficult to minimize.

The most important step is to eliminate exposure to aspirin and non-food sources of salicylates. If there’s no improvement, consider reducing food sources with either a low-salicylate diet or a low-FODMAP diet.

Always talk with your doctor before making any changes.

Salicylate intolerance is not well-understood, and often misdiagnosed. This article looks at the evidence-based ways to treat salicylate intolerance.

  1. The 3 day diet is not low sals. I have sals intolerance and would be ill if I fo,llowed your diet. For example the only low sals lettuce is iceberg, tomatoes are high sals. They basically rip; my stomach apart my reaction is so bad to them. There are many other examples here of high sals. Plesae ensure your information is correct before publishing. The RPAH in Sydney is the world leder in this – but is not mentioned anywhere.

  2. I recently been asked to do an elimination diet for three weeks for my 7 years old….heard many mums with ADHD children have found an improvement by removing the high content foods. Not quite convinced as couldn’t find any studies confirming calculates linked to hyperactivity. I can see you haven’t mentioned it at all in your article. I might give him a go with fodmap which is less restrictive.

    • Hi, A complete elimination diet might be going a bit far but taking all the additives out of a diet would a great idea. I’ve heard a lot of wonderful stories come out of the mouths of mothers who have done this. It’s awful when you think of the things that these people can put into packets these days and actually call it food. I go cross eyed trying to read lables, or I did until I stopped and when onto all natural stuff.
      Yours sincerely Toni.

  3. This is the worst list I’ve ever seen. I’ve been salicylate sensitive for more than thirty five years and I know there is probably fifty or sixty items missing off this list. The only one that is nearly right is the herbs which I have to agree with. When It comes to the fruits and vegies it’s only fifty percent right and where there drinks are concerned…..well you can walk through the supermarket with your eyes shut. There’s nothing you can pick up off the shelves except water and milk. All the other stuff which is just frrit and coloured water is off the list. Teas especially.

    • I recently suffered anaphylaxis after taking 2 soluble aspirin for a headache. For 2 months prior to this I had been experiencing intermittent rashes/hives, headaches, lethargy and occasional vomiting for no obvious reasons. Various food allergy tests have been carried out with the only positive result being egg white. After seeing a dermatologist last week he suggested that I check out salycilates. Wow, what a minefield? I am determined to crack this and would be grateful for the benefit of your personal experience as I find the food lists quite confusing. Many thanks

      • I am very similar to you last year i went into anaphylactic shock and was passed out by time ambulance came from taking asprin. I never had an alergy before then. Since then i have been experiencing awful stomach pain vomiting, bloating and reactions. Only through my own research i found out about salacites in foods products etc my immunologist never told me anything about avoiding foods or products. Since elimating anything on high list from my diet i do not have any more symptoms.

    • HELP Please….I have had severe acid reflux for 8 years and thought I d tried every diet, but had not heard of salicylate, histamine issues. Can someone recommend a diet that has NO allergy/salicylate/histamine/etc.. issues….at this point I just want to rule out that it could be ANYTHING I am eating, but I don’t know where there might be a list that covers it all so I can just jump in and see. Also, if I do this type of long is a fair time to try it to see if it effects my reflux. Thanks…you all seem to have more knowledge than I do and doctors are just not helping at this point.

      • Hi,I had acid reflux for around 15 years and took prilosec or some other pill for it every day. If I missed a does I thought I was going to die. due to chronic hives for 24 years I decided to try the elimination diet to see if I could get the hives under control. I had tried other things, juice fast ect. 4 weeks in I stopped taking my prilosec one day. I was just waiting for (all you know what) and nothing happened . I had no acid reflux. It was a miracle. Its been about 2 week off meds and not one bit of reflux. None! I still cant believe it.The the doctor tells me I have to be on this diet for 4 to 6 months to clear and heal my immune system and hives.I pray this helps you. I thought I would be on prilosec forever and it is very dangerous. Its like the doctors want you on the meds . No one had any advice for me. On the diet I was very weak the first couple of weeks …getting off the sugar. I ate a lot of melon that helped me sugar level out .
        My hives are not better at all but my doctor said 4 to 6 months . I will do anything at this point to heal my body so I am going to keep doing it. Check with your doctor and see what they think. I hope and pray for you . I know how bad reflux is and Im so thankful that I have at least cleared that up.

      • I am 67 years old. Self-diagnose SALS intolerance about 5 years ago. My life has drastically changed for the better. Here is the site taught me:

        Much info and it will take a while to comprehend. When I first started the diet I ate only the foods in the very low and low categories. I noticed a difference in a few days. Ate only those foods for the first 2 weeks. Keep in mind that even some of the foods in these categories can have an adverse reaction. I now limit myself to 1 or 2 servings from the medium category a day. There are days I have food that I shouldn’t and I pay dearly for it for 2 to 3 days. Its all trial and error. But once your body starts to feel better there is no going back to old eating habits. You won’t want to. And I need to share. Mom use to say if you are hungry you will eat anything. Believe me, the food may get boring but Mom was right, of course! Wait long enough and the boring food tastes great. Over the years I’ve found Malt Vinegar is delicious. Did not like it at first. Hope this info helps you. Good luck!

    • Go to The food list there is accurate and comprehensive. I live by it. Otherwise it’s hives and anaphylaxis with an unpleasant 30 minute sit on the toilet.

  4. Start with Australian RPAH like Joyce said. Also Sue Dengate’s Fed Up and the Failsafe Cookbook, as well as her website Food Intolerance Network. There is also a blog called Cooking for Oscar that would be helpful for anyone dealing with Salicylate Sensitivy/Intolerance. They’ve been lifesavers for me since the end of March when I became histamine and salicylate sensitive in conjunction with my seasonal allergies.

    • Hello all that feel/know they are salicylate intolerant. I discovered this for myself at 5 yo – some 55 years ago now – but was told I was imagining it and just get on with eating what was dished up. At the ripe age of 40 I finally rediscovered the link between migraines, constant unwellness, and nausea – and it was all the healthy salads and coffee I was consuming topping up my toxic chemical content. I was so over the couple of days off per month without a migraine – and the constant black bags under my eyes from the repetitive toxins I was consuming under the guise of healthy food – that I sought out an allergist.

      I was advised that whilst I didn’t have “an allergy”, the nasal inflammation and repetitive migraines – and possibly my lifelong dance with rheumatoid arthritis and being unwell indicated there was something amiss. Having been then referred to a dietitian, I proceeded to undertake the ELIMINATION DIET to determine what my cause was. THIS WAS BRILLIANT – although testing at times – BUT I HAD VALIDATION OF WHICH NATURAL FOODS WERE POISONING ME CONSTANTLY, by my own hand.

      This is not a quick fix, but if you have the same problem as me, this process helps find your triggers and helps you become well again. I have been on a very low salicylate diet now for 20 years, and I know that when my stress levels go up, my tolerance levels drop rapidly, and then if I eat the wrong things, I’m back to migraine and nauseous territory for days/weeks.

      PLEASE KEEP IN MIND that when you eat something your body reacts badly to, it can take days/weeks to get this out of your system. Prevention is better than cure, so find your trigger/s and drastically reduce or eliminate those triggers. MELONS are not anywhere near my diet these days or gravy/sauces, and DON’T FORGET, if you’re eating off a fruit platter – with mixed fruits – the juice is just as toxic to you as the fruit itself. So don’t eat off anything that is not separated to meet your needs.

      I hope this helps,

  5. has a fantastic compiled food sensitivity comparison guide that lists whether a food is low, medium, or high in histamines, amines, glutamates, oxalates, salicylates, sulfites, thiols, and nightshade. It’s proven accurate when compared to lists like the RPAH and the SIGHI list of histamines. I went through and compiled a list of low lows, then low mod foods that saved my sanity when shopping for things I could comfortably eat. A big part is definitely removing the food additives, food colors, and extra sugar that so many commercial products contain. Good Luck.

  6. HELP Please….I have had severe acid reflux for 8 years and thought I d tried every diet, but had not heard of salicylate, histamine issues. Can someone recommend a diet that has NO allergy/salicylate/histamine/etc.. issues….at this point I just want to rule out that it could be ANYTHING I am eating, but I don’t know where there might be a list that covers it all so I can just jump in and see. Also, if I do this type of long is a fair time to try it to see if it effects my reflux. Thanks…you all seem to have more knowledge than I do and doctors are just not helping at this point.


  7. What is the best option for pain relief. I cannot take aspirin due to severe breathing problems, but I seem to also struggle with paracetamol. Am I imagining the paracetamol reaction or is there a definite connection between paracetamol and silicylates. I’ve tried codeine but it makes me nauseous and seems to be a weak pain killer. Any options would be grateful

    • Hi Alan, Iv’e been allergic to NSAIDs for years and me Dr. gives me a prescription for a muscle relaxer for times when my back or neck are sore. These probably wouldn’t work on headaches though, luckily I don’t get those.

    • I have the same problem and I’m desperate for a pain killer for headaches! Any ideas would be much appreciated! Thanks.

  8. I got the intolerance for over 7 years, every time I eat tomato or drink too much coffee, honey, the asthma will attack and I must use the Prednisolone at least 20mg per day.
    Around an half year ago, I just tried to take 2 pills fish oil daily after read your post, it’s really helpful. Thanks a lot for your information.

  9. I am so glad that others have jumped in to note how ill-informed the list of salicylates is in this article – I would be really ill if I ate that 3-day diet! And the comment about “plenty of fruit and veg for kids” if kids are sals sensitive this would not help at all. I cannot eat any fruit even ripe green pears which are supposed to be the lowest sals fruit.

    I used the Fed Up web site to work out what to eat – if you have kids with issues it is good to work with a dietitian who is completely familiar with FAILSAFE diet. FAILSAFE stands for: Free of Additives, Low in Salicylates, Amines and Flavour Enhancers. I do have to say the Fedup web site is not easy to use but once you work out how to use it the info is the best out there (the program is the one that Sue Dengate from the Royal Prince Alfred Hospital in Sydney Australia has worked on). There are books you can get with clearer info. Yes, cooking for Oscar is good.

    I am also sensitive to amines which the FAILSAFE diet deals with that too.

    Really important to eliminate non-food sources of Sals (especially for kids) – toothpaste and even the mildest soap is a problem for me. I use charcoal tablets for brushing my teeth (which is the best tooth cleaner there is) and use DermaVeen products for body and hair washing. Perfumes must be avoided at all costs!.

    Am going to try fish oil to see if it reduces symptoms.

  10. “The mechanism by which aspirin and other pain relievers containing salicylates affect asthma is not clear…” FALSE. Many studies have shown that in aspirin-sensitive asthmatics (AERD, Samter’s Triad) are reacting to NSAID medications (including those that are NOT salicylates) because they inhibit the COX-1 enzyme. We are reacting to the “acetyl” part of aspirin NOT the salicylate. Experts on these diseases do not recommend avoiding dietary salicylates because they do not inhibit COX-1 and would not cause a reaction. Please inform yourself.

  11. I have been salicylate intolerant almost all my adult life.( I was born with severe eczema.) However, I was only diagnosed about 2 years ago, by a frustrated doctor as a throw away line, after I was unable to tolerate the supplements she was prescribing to improve my gut health! As I was leaving her surgery, she suggested in quite a loud voice, that I google salicylates! How my life has changed!!
    Just a few warnings…..
    Watch manufacturers carefully. If I see ‘new and improved’ on an item now I panic! Recently, have been caught with worrying results. First on was Coles bread which was recommended by the dietitian from the Salicylate Intolerance clinic at RPA hospital here in Sydney. When the loaf was reduced to $1.80 a loaf I thought I was on a winner. But no, after only a few weeks, I knew something was wrong, and discovered they had substituted palm oil for the recommended canola oil. Also Arnotts Scotch Finger biscuits, which were my sweet treat, substituted palm oil in all of their biscuit range ( excluding Cruskits). I can no longer eat Arnotts!
    I have found a local doctor here now, a new graduate, who is very interested in my situation. As a last resort, I needed to seek medical advice, because one of my symptoms of salicylate overload is rheumatic like pain in my joints, and my hands had locked up! I now take prednisone when I flare up, but I am only able to take any drug for 2 or 3 days. His parting words to me when I was leaving his surgery were…… C …you are between a rock and a hard place, but you have to get your levels down! Easier said than done! Welcome to my world!

  12. I have had aspirin/ NSAID allergy since my mid 30’s when I also began to have hives and asthma, along with sinusitis and later nasal polyps. Lost my sense of smell 10 years later and started having recurrent respiratory infections in my 50’s. 6 years ago things got so bad – I was wheezing and coughing most of the time and getting itchy rashes, I couldn’t sleep properly and so became fatigued. When I got ear infections and eye infections and became sensitive to preservatives in medicines and foods…especially sodium benzoate, I began to panic. I started a medium to low salicylate diet 5 years ago and it was magic !
    I stopped itching; I stopped wheezing and coughing at night; my rhinitis improved as did my hayfever interestingly; nasal polyps began to reduce over the next year and occasionally my sense of smell returns. I have been on this diet for more or less five years. I know how much salicylate foods I can manage. I feel the itching if I’ve over done it. It does mean I can occasionally have a tomato based sauce or a small glass of red wine, as long as I don’t have them together

    • omega 3 can heal, extra virgin olive oil can increase the DAO, folic acid other B’s help balance, watch out for the olive oil try small amount on skin first, I put too much on and since my Magnesium levels are high and olive oil is high in magnesium I went over my bucket and got half an hour of drizzle in both my eyes. Like rain on the window in my eyes, very trippy and scary first time in happened when I was driving from soaking in epson salts too much. It is one of my symptoms when I go over my bucket, another is vertigo and of course all the regular stuff like hives, rashes, itchy eyes, skin, diarrhea etc. etc. I’m going to try zinc to lower my magnesium levels, got blood tested it is on the very edge of the high level. Drizzle in my eyes is very annoying! Hard to drive can strike whenever. Luckily it passes. Also going to try natural progesterone as getting a hysterectomy soon and assume my allergy symptoms will get even worse now after reading the link between these hormones and allergies.
