Two Types of Inflammation: Acute vs Chronic
Acute inflammation is the kind you know: a swollen ankle after a sprain, redness around a cut. It is fast, localised, and beneficial — part of the healing response. Chronic low-grade inflammation is different. It is slow, systemic, produces no dramatic symptoms on its own, and operates beneath clinical detection thresholds while continuously damaging tissues over months and years. It is now understood to be a central driver of acne, eczema, IBS, type 2 diabetes, cardiovascular disease, and many autoimmune conditions. Diet is its most modifiable fuel source.
How to Measure It
Chronic low-grade inflammation is assessed through blood biomarkers. Key ones include:
- C-reactive protein (CRP): Produced by the liver in response to IL-6; elevated CRP correlates with inflammatory activity
- Interleukin-6 (IL-6): Cytokine that promotes inflammation; chronically elevated in poor-diet populations
- TNF-alpha: Tumour necrosis factor; elevated in inflammatory bowel conditions and metabolic syndrome
- Fasting insulin: Proxy for insulin resistance, which drives and is driven by chronic inflammation
You do not need regular blood tests to act on this information. Diet patterns that raise these markers are well-established, and so are the patterns that lower them.
Pro-Inflammatory Foods
The following dietary patterns consistently raise inflammatory biomarkers in clinical research:
- Refined sugar and high-fructose corn syrup: Elevates insulin, AGEs (advanced glycation end products), and directly activates NF-κB (a key inflammatory signalling pathway)
- Refined seed oils (corn, soybean, sunflower, safflower): High in omega-6 linoleic acid; excessive omega-6 shifts the eicosanoid balance toward pro-inflammatory prostaglandins
- Ultra-processed foods: Combine refined carbs, seed oils, emulsifiers, and additives that collectively disrupt gut barrier function and microbiome composition
- Refined carbohydrates: Rapidly digested, driving insulin spikes and AGE formation with minimal fibre or nutrient content
- Excess alcohol: Damages gut barrier function, increases intestinal permeability, and elevates LPS (bacterial endotoxin) in the bloodstream
Anti-Inflammatory Foods
Foods and dietary patterns associated with reduced inflammatory biomarkers:
- Omega-3 fatty acids (EPA and DHA): Found in fatty fish, flaxseed, walnuts; compete with omega-6 for eicosanoid production, shifting the balance toward anti-inflammatory resolvins
- Polyphenols: Found in berries, dark chocolate, extra virgin olive oil, green tea; inhibit NF-κB and reduce oxidative stress
- Fermented foods: Support microbiome diversity and SCFA production, which reduces gut permeability and systemic LPS translocation
- Leafy greens: High in folate, magnesium, and anti-oxidants that reduce homocysteine and oxidative stress
- Turmeric (curcumin): Clinically studied NF-κB inhibitor; bioavailability improves significantly with black pepper (piperine)
How Inflammation Connects to Acne, Eczema, and IBS
Chronic systemic inflammation does not cause these conditions independently, but it lowers the threshold for trigger reactions. A baseline state of low-grade inflammation means that each trigger food produces a bigger immune response — more sebum, more skin barrier disruption, more gut hypersensitivity. Reducing background inflammation through diet therefore reduces the severity of individual trigger reactions, even before specific triggers are identified.
How Sensio Solves This
Sensio logs your meals by photo and correlates them with your skin and gut symptoms across the 24–72 hour delayed reaction window. Beyond identifying specific triggers, the pattern data reveals whether high-processed-food days consistently precede worse symptom days — capturing the cumulative inflammatory load effect that individual meal analysis misses. Over weeks, you see not just which specific foods are your triggers but what your overall dietary inflammation pattern looks like.
FAQ
How long does it take for dietary changes to reduce inflammation?
CRP can begin to fall within 2–4 weeks of consistent anti-inflammatory eating. Skin and gut symptoms often show meaningful improvement over 4–8 weeks as background inflammation reduces and trigger sensitivities lower their threshold.
Do I need to eat a completely clean diet to see benefits?
No. The inflammatory diet effect is dose-dependent. Reducing ultra-processed food from daily to 2–3 times weekly while adding more omega-3 sources and vegetables produces meaningful changes in inflammatory markers without requiring perfection.
