One of the most common things people tell us is that their skin "seems worse after certain meals" — or that it mysteriously improves on holiday, when their diet naturally changes without them thinking about it.
These are not coincidences to dismiss. They are observations worth taking seriously. But the relationship between food and skin is more nuanced than the simple idea of a single "bad food" to cut out.
The Gut, the Skin and the Immune System
The skin, the gut and the immune system are in constant conversation. A large part of the immune system lives in and around the digestive tract. When digestion is under strain, the effects can show up far from the gut itself — including on the skin.
This is why we spend so much time, during a consultation, understanding digestion. Not because every skin condition is caused by food, but because the gut is so often part of the broader picture.
Intolerance Is Not the Same as Allergy
A food allergy is an immediate, often dramatic immune reaction. A food intolerance is quieter and slower — a low-grade response that can build over hours or days, making it far harder to spot.
This is precisely why intolerances are so easily missed. The reaction is delayed and subtle, so the connection to a particular food is rarely obvious from everyday experience alone.
How We Investigate
We begin with your complete history — what you eat, how you feel, and how your skin behaves over time. Where helpful, we may also use a non-invasive computer controlled food intolerance screening system to gather additional information.
This screening is never used in isolation. It is a supporting tool, interpreted alongside your full clinical history. The consultation itself — the questions, the listening, the pattern recognition built over decades — remains our most valuable investigative tool.
The goal is never simply to hand you a long list of foods to avoid. It is to understand your individual picture and build a strategy that is realistic and sustainable for you.
Key Takeaway
Food is rarely the sole cause of a skin condition — but understanding your individual food, gut and immune picture is often a crucial part of the story.
