Salicylate Foods - sensitivity, intolerances and food list.

Salicylates – what are they exactly?

Salicylates are natural compounds found in the plants that we eat that act as protective measures for the survival of the plant. The protection is imposed against opportunistic pathogens that may affect the plant's health or abiotic factors such as temperature changes, water differentiation, atmospheric changes like oxygen levels, chemical elements such as acidity or mineral changes to the soil, and wind funnily enough as wind affects all other factors above consequently.

Why do Salicylates benefit humans?

Phenolic compounds like that of Salicylates exist to benefit the survival of plants and have both positive and negative health factors for humans depending on the form. Both natural and pharmaceutical synthetic forms of existing salicylates elicit multiple beneficial responses in humans. Studied to be effective towards the approach of :

• Neuroprotective.
• Antidiabetic.
• Anti-inflammatory.
• Reduction of oxidative stress.

The synthesis of pharmacological salicylates in the form of Asprin was one of the most incredible discoveries of its time, however, its actual natural origins date as far back as Hippocrates, most famously known as ‘the father of medicine’. Hippocrates discovered the effects of salicylates when prescribing extracts from willow leaves or barks to women during childbirth to relieve pain . The active ingredient of this extract was found to be salicylic acid when isolated, converted to salicylic acid upon ingestion. Heading into the 19th century it was again used frequently for the treatment of inflammation and in 1897 Pharmaceutical company, Bayer, synthesized it into a product we have come to know as Asprin.

What happens when we get too much of a good thing?

As humans, it can be common to come across overload and or intolerance of compounds in our system. When we overload the circuit unintentionally with good intentions it can wreak havoc in unfair ways. One of these is seen with Salicylate intolerance, an intolerance rarely talked about, however, is one of the most searched intolerance terms we have come across! Figuring out what an intolerance is can be difficult as it’s not an instant allergen response or necessarily something that requires the action of the immune system. Its often an accumulation met with a maximum threshold. Salicylate intolerance has been known for more than 100 years now and yet, not adequately recognized by research until more recent years.

So, if you are experiencing some of these bizarre symptoms and suspect an intolerance to salicylates, it may be something to address for yourself and with your health care professional. Symptoms of salicylate intolerance include:

• Respiratory irritation – asthma-type responses.
• Headaches/migraines.
• Gastrointestinal discomfort.
• Increased frequency of urination.
• Irritability, restlessness, and attention difficulties.
• Sleep disturbances.
• Tinnitus.
• Joint pain, inflammation, and arthritic complaints.
• Swelling and fluid retention.
• Mouth ulcers and rash around lips.
• Persistent cough.
• Sore, itchy, watery, or burning eyes.
• Muscle tremors and twitches.

All of these symptoms sound very similar to histamine responses – it's technically not an immune response, although it feels very much like one! Histamine is exhibited in response to foreign pathogens. Salicylates are different in this instance.

What’s happening with Salicylate Intolerance inside of us?

Salicylates, among many other compounds such as analgesics and anti-inflammatory drugs, particularly the non-steroidal anti-inflammatory options you can opt for, inhibit Cyclooxygenase which is the mediator for the synthesis of prostaglandins. Prostaglandins are lipid groups that are involved at the site of injury or illness to control processes around inflammation, blood flow, the formation of blood clots, and also the induction of labor in pregnant women.

An individual’s intolerance to Salicylates, while there is an inhibition of Cyclooxygenase, there is an activation of Basophils, Eosinophils, macrophages, mast cells, platelets, and lymphocytes. Just so we don’t lose you; these cells all play an essential role in the secretion of active substances in the body that cause what is known as a ‘pseudo-allergy’ response. This is because it’s likely to be more an enzyme deficiency caused by intake of COX (cyclooxygenase) inhibitors such as phenols/salicylates and low functional levels of PST (phenol-sulfur-transferase).

Can you test for a phenol/Salicylate intolerance?

Phenols and salicylates are processed through the liver via phase 2 conjugation and this process requires:

• Glutathione.
• Sulfur (Sulta1A).
• Glycine.
• Phenol-sulfur transferase (PST).
• Glucuronic acid.

However, most commonly this is an issue with a PST deficiency. This enzyme breaks down these compounds into what can be used and what can be disposed of and removed from the body. Thus, when deficient, an accumulation occurs of these salicylate compounds and causes the effects mentioned above.

An Organic Acid Test is one of the best measures for identifying areas of deficiency that may be inhibiting the effective conjugation and removal of salicylates from the body effectively. You can request an Organic Acid Test and have it interpreted through our practitioner service with ATP Science or if you have an available naturopath/practitioner to you, you can request the Organic Acid Test this way.

Please note:

This page is only a guide, the list of salicylates is forever changing and we do not update this list. This is a simple blog as we saw a need to share some form of the guide with everyone as there is minimal information out there.

Phenylethyl salicylate Red dye (#40) Salicylaldehyde Salicylamide Salicylate Salicylic acid Sodium salicylate Spearmint Yellow dye (#5 and #6)

Vitamin B6 in large amounts can be a common denominator in the depletion of this enzyme and downregulation of sulfation pathways, however, foods higher in magnesium upregulate this pathway.

Salicylates in medications and alternative medicines

Pharmaceutical medications, herbal remedies, and lotions, ointments, and creams may all contain salicylates.

Your healthcare practitioner can advise you on salicylates and your prescription.

Do not change any prescribed medicines without consulting with the prescribing doctor first.

Tips for living with salicylate sensitivity:

• Thickly peel fruit and vegetables.
• Eat fruit and vegetables as ripe as possible.
• Discard the outer leaves.

Pro Tip: The Amino Acid Glycine helps to conjugate up or bind with Salicylates so adding this in with meals is a great way to offset some of the absorptions, this then gets excreted by the kidneys.
