When patients think about food and skin health, they typically think about whole foods — dairy, wheat, eggs, nuts. And these are certainly areas worth investigating.
However, one area that receives far less attention — yet features prominently in our clinical observations — is the potential role of food additives.
Preservatives, artificial colours, flavour enhancers, artificial sweeteners, and other chemical additives are now present in an extraordinary range of everyday foods.
How Widespread Are Additives?
Most families consume food additives every day without realising it. They appear in bread, sauces, snack foods, processed meats, breakfast cereals, soft drinks, chewing gum, vitamins, medications and many restaurant meals.
The average Australian may be exposed to dozens of different chemical additives daily. While individually each additive may be present in small quantities, the cumulative exposure deserves consideration.
What We Have Observed
Over more than 65,000 consultations, we have frequently observed patients whose skin symptoms improved significantly when their exposure to certain food additives was reduced.
Common additives of interest include monosodium glutamate (MSG and its related numbers), artificial colours (particularly the azo dyes), certain preservatives (sulphites, benzoates, sorbates), and artificial sweeteners such as aspartame.
We do not claim these additives "cause" skin conditions. But in susceptible individuals, they may represent one contributing factor worth investigating.
The Practical Approach
Our consultations provide practical guidance on identifying additive exposure, reading food labels, and making manageable dietary adjustments that reduce unnecessary chemical intake without creating an overly restrictive or stressful lifestyle.
The goal is always understanding and balance — not fear or perfection.
Key Takeaway
Food additives are one area of investigation that can produce surprisingly meaningful insights for some patients with chronic skin conditions.
