Is zinc deficiency causing your allergies?

Low zinc levels can affect almost every aspect of your health because zinc is an 'essential' trace element, meaning it is a vital nutrient for life. Although severe zinc deficiency is very rare, marginal zinc deficiency affects 31 per cent of the global population (1).

Zinc deficiency and allergies

Zinc plays a major role in storing histamine in the body. So, when there's a deficiency, the body releases more histamine into the surrounding tissues. High histamine levels can increase your overall sensitivity to food and environmental allergens, and may also contribute to histamine intolerance.

Zinc and leaky gut

Leaky gut is a condition where the intestine becomes permeable (‘holey’), which can spark chronic inflammation and allergy-related conditions, such as eczema and IBS. Studies have shown that zinc supplementation can strengthen the gut lining and support immune system function (2).

How to find out if you are zinc deficient

The best way to identify whether you have a zinc deficiency is by requesting to have your zinc levels checked as part of a regular blood test with your GP.

Improving your zinc levels


Depending on your level of deficiency, increasing your dietary intake of zinc may be enough. Focus on boost your intake of zinc-rich foods, such as:

  • pumpkin seeds
  • grass-fed beef
  • lamb
  • cashews
  • chickpeas
  • mushrooms
  • chicken
  • kefir/yoghurt
  • spinach
  • cocoa powder


If you are not getting enough zinc through your diet, supplementation may help. Speak to your health professional about getting the right zinc supplement for you.

Do you suffer from allergy symptoms? Try our Natural Allergy Treatment! The Naturopaths at HWA use a form of muscle testing (or kinesiology) to discover which food or environmental substances may be contributing to your scalp dryness. We then perform a natural allergy treatment which aims to reduce your reactions, called Positive Association Technique (PAT).

PAT is a non-invasive holistic therapy, which:

  • draws on acupressure and kinesiology techniques
  • aims to re-train your body
  • may reduce your reactions to food and environmental substances that may be causing or exacerbating your allergy symptoms

This blog is intended as general information only. PAT cannot diagnose or cure allergies – it is intended to decrease reactions and help manage symptoms. It is not intended to raise unrealistic expectations. If symptoms persist, consult your GP.
