The latest nasty showing up in sugar-free foods and drinks is E223. It’s especially triggering for asthmatics, and destroys Vitamin B1 in the intestine. This additive does not provide any beneficial effects whatsoever to the human body.
E223 (Sodium Metabisulfite) is classified as a sulfite and while approved for use in small quantities, E223 destroys Vitamin B1 in the intestine and alters the balance of beneficial and harmful bacteria in the gut. Leading to disruption of the intestinal barrier, creating inflammation.
But that's not the worst. It can trigger severe allergic reactions - including asthma attacks and anaphylactic breathing difficulties - in sensitive individuals, particularly asthmatics.
The concern here is that New Zealand consistently has one of the highest asthma prevalence rates in the world, affecting roughly 10% of the general population. This places it well above many OECD nations, particularly for children and adults. Unfortunately, that rate is even higher at 20% for Maori and 15% for Pasifika.
Here is what E223 does in the body:
• Metabolism: When ingested, E223 breaks down into sulfites, which are metabolised in the liver into sulfates and excreted in the urine.
• Allergic-Type Reactions: In sulfite-sensitive individuals, E223 can trigger asthma-like symptoms, including wheezing, chest tightness, coughing, and breathing difficulties as it narrows the airways.
• Irritation: It can cause gastrointestinal issues, including nausea, diarrhoea, abdominal pain, and heartburn.
• Skin Reactions: It can trigger allergic contact dermatitis, hives, and skin rashes.
• Nutrient Degradation: Sulfites can destroy vitamin B1 (thiamine) in the digestive tract. Vitamin B1 is a vital water-soluble nutrient that converts fat, protein, and carbohydrates into energy, essential for metabolism and proper nerve, muscle, and heart function. It acts as a coenzyme in energy production, supports immune system health, and plays a role in cognitive function.
• Potential Long-Term Effects: Some studies have suggested it may destroy gut microbiota, damage the intestinal mucosa, and cause potential neurotoxic effects (e.g., delayed visual response).
So you can put E223 down as another ingredient to be wary of, and to be very careful to avoid giving products like sugar-free syrups that contain E223 to anyone with asthma.
