I want to address a topic that is very close to my clinical work and personal passion—the relationship between diet, inflammation, and chronic skin conditions such as psoriasis and eczema.

Recently, I have seen a growing number of people sharing their dietary changes online in an attempt to reduce inflammation and support skin healing. While it is encouraging to see individuals taking an active role in their health, the information shared is often inconsistent or not grounded in science.

Because every individual is unique, food triggers can vary significantly—some people react to dairy, others to eggs or specific additives. However, for the purpose of this article, I will focus on research-backed mechanisms associated with psoriasis and systemic inflammation.

1. Gluten and Psoriasis: The Link with Inflammation and Metabolic Health

Gluten remains a controversial topic, but in clinical and research settings, there is growing evidence suggesting a connection between gluten consumption, inflammation, and psoriasis severity, particularly in individuals with underlying metabolic dysfunction.

Importantly, if gluten makes you feel unwell, that physiological response should not be dismissed or overly intellectualised—your body is communicating a potential inflammatory reaction.

For individuals with psoriasis (without coeliac disease), research has identified several relevant associations:

• Moderate to severe psoriasis is often linked with metabolic syndrome

• Metabolic syndrome contributes to insulin resistance

• Insulin resistance is associated with increased systemic inflammation

Some studies suggest that gluten may contribute to inflammatory load and metabolic disruption in susceptible individuals.

Research has also indicated that a gluten-free diet may reduce inflammation, adiposity, and insulin resistance in certain populations by influencing metabolic regulatory pathways (Soares et al.).

2. High Glycaemic Index Foods and Insulin Resistance in Skin Conditions

Dietary carbohydrates with a high glycaemic index (GI) can contribute to rapid blood glucose spikes, which may worsen insulin resistance over time.

Insulin resistance is a known driver of systemic inflammation and has been associated with increased severity of psoriasis flare-ups.

To support metabolic balance and skin health, a low glycaemic index dietary approach is often recommended.

Better carbohydrate choices include:

• Brown rice

• Quinoa

• Buckwheat

• Millet

However, portion control is equally important. Even low-GI carbohydrates can contribute to metabolic stress if consumed in excess. A general guideline is to keep carbohydrates to approximately one-eighth of the plate, adjusted for individual needs (such as pregnancy or breastfeeding, where requirements differ).

3. Exercise, Inflammation, and Psoriasis Management

Exercise plays a significant role in regulating inflammation, glucose metabolism, and insulin sensitivity, all of which are relevant to chronic skin conditions.

While movement is essential for overall health, the type of exercise matters.

Strength training may:

• Improve insulin sensitivity

• Enhance glucose uptake into muscle cells

• Reduce systemic inflammation

• Support metabolic balance associated with improved skin outcomes

This is particularly relevant for individuals managing psoriasis linked to metabolic dysfunction or insulin resistance.

4. Yeast, Fermented Foods and Candidiasis Considerations

Yeast-containing foods are often discussed in relation to gut health and skin inflammation, particularly in individuals with suspected candidiasis or gut dysbiosis.

Common sources include:

• Bread and baked goods

• Yeast-based spreads (e.g. vegemite)

• Fermented foods (which naturally contain live yeast cultures)

In some individuals, fermented foods may aggravate symptoms, potentially due to microbial imbalance or sensitivity responses.

If you notice consistent symptom flare-ups after consuming fermented or yeast-containing foods, it may be worth moderating intake and exploring gut health-focused dietary strategies under professional guidance.

5. Gut Health, Leaky Gut and Autoimmune Skin Conditions

The gut plays a central role in immune regulation, with approximately 70–80% of immune activity occurring within the gut-associated lymphoid tissue.

When the intestinal lining becomes compromised—often referred to as increased intestinal permeability or “leaky gut”—larger, partially digested molecules may enter the bloodstream.

This can trigger immune activation and chronic inflammatory responses.

Contributing factors may include:

• Poor diet

• Chronic stress

• Alcohol consumption

• Medications

• Infections or illness

Over time, persistent immune activation may contribute to autoimmune and inflammatory skin conditions such as psoriasis and eczema in genetically susceptible individuals.

For further reading, research has explored the gut–skin–immune connection in psoriasis (e.g. PubMed: 29908580).

Understanding Psoriasis Triggers: A Holistic Perspective

Psoriasis is a complex inflammatory condition influenced by multiple internal and external factors.

Rather than focusing on a single cause, it is more effective to understand individual triggers and patterns.

Common contributors include:

• Dietary inflammation

• Gut dysfunction

• Stress and emotional load

• Hormonal fluctuations

• Blood sugar instability

• Immune dysregulation

Practical Self-Tracking for Skin Health

One of the most effective tools for managing psoriasis and eczema naturally is self-awareness.

Keeping a daily journal can help identify personal triggers, including:

• Food intake

• Stress levels

• Exercise patterns

• Sleep quality

• Menstrual cycle changes

• Hydration levels

Over time, this helps build a personalised understanding of what influences your skin health most significantly.

Final Thoughts on Managing Psoriasis Through Lifestyle

Psoriasis, like many chronic inflammatory conditions, is influenced by a combination of internal and external triggers. While there is no single dietary solution, understanding how food, gut health, metabolism, and lifestyle factors interact with the immune system can significantly improve long-term management.

The goal is not to “fight” the condition, but to understand it—so you can reduce flare frequency, improve quality of life, and support healthier skin over time.
