Allergies

Updated: Sep 11, 2023


Spring is a time of blooming buds and lush, thriving grass.

But with the blossoming flowers and warmer winds comes an increase in seasonal allergies.


Allergies are an overactive immune response to a normally harmless substances such as pollen or certain foods. This is your body’s immune response to the perceived threat (allergen).


This can result in:

  • Sneezing

  • Runny nose

  • Congested sinuses

  • Watery/itchy eyes

Common allergens include:

  • Pollen

  • Dust

  • Grass

  • Mould

  • Animal hair

  • Insect stings

  • Air pollutants

Hay fever

Allergic rhinitis or commonly known as hay fever affects 1 in 5 Australians. It occurs when an allergen such as pollen or dust is inhaled by a susceptible individua triggering the production of the allergic antibody immunoglobulin E (IgE). This then causes the release of histamine, resulting in itching, swelling and mucus production.

Symptoms vary from individuals:

  • Sinus and nasal congestion

  • Hives and digestive disturbances

  • Headaches and fatigue

  • Nausea or vomiting

Histamine intolerance is not a sensitivity to histamine, but an indication that there are excessive histamine levels.

Histamine is usually eliminated from the boxy by two enzymes, diamine oxidase (DAO) and histamine n-methyltransferase (HNMT).

The function of these two essential enzymes can be impaired by many factors, including gastrointestinal issues, hormones and genetic predisposition.


Antihistamine Diet

Some foods can either be high in naturally occurring histamine or block the DAO enzyme.

If you suspect high histamine try reducing histamine-rich foods.

Histamine is often produced by ageing and fermentation. Enjoy fresh fruits and vegetables and avoid leftovers, especially meat.

Other foods to avoid include:

  • Fish (Mackerel, Herring, Sardines, Tuna)

  • Meats (Sausage, salami, ham)

  • Aged cheeses

  • Vegetables (sauerkraut, spinach, eggplant)

  • Alcohol (wine both red and white, beer, champagne)

Natural solutions for allergic rhinitis.

Gut health and Histamine Intolerance

Histamine intolerance has been shown to play a significant role in gastrointestinal disorders. Symptoms can include abdominal pain, bloating, and diarrhoea.

It's important to support gut health through improving gut barrier integrity, reducing inflammation and restoring a healthy microbiome.

Supplements

Quercetin

Is one of my favourite supplements for allergies and in particular hay fever.

Quercetin, a bioflavonoid has been shown to exert significant anti-allergy effects by preventing the release of histamine.

Vitamin C boosts immunity and is a natural antihistamine.

Bromelain is a compound found in pineapples, as well as supplements. It has anti inflammatory properties, especially for the sinuses.

Probiotics - a good multi-strain probiotic has been shown to modulate the immune response to harmful antigens and down regulate hypersensitivity reactions (2).
