Chronic Inflammation
Chronic low-grade inflammation underlies most modern chronic diseases — cardiovascular disease, type 2 diabetes, cancer, Alzheimer's, and autoimmune conditions. Diet is one of the most powerful modulators of the inflammatory state.
The Inflammatory Diet Connection
Inflammation is measured by biomarkers including C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). These are elevated in obesity, metabolic syndrome, and chronic disease states, and dietary patterns strongly predict their levels. The Dietary Inflammatory Index (DII), developed from 1,943 studies, scores individual foods by their inflammatory potential.
The most anti-inflammatory dietary pattern identified is the Mediterranean diet — a 2019 meta-analysis of 17 randomized trials found Mediterranean diet adherence reduced CRP by 0.58 mg/L and IL-6 by 0.33 pg/mL, statistically and clinically significant reductions associated with lower cardiovascular and cancer risk.
Specific anti-inflammatory powerhouses: curcumin (turmeric) inhibits NF-κB and COX-2 enzymes; omega-3 EPA/DHA suppress eicosanoid inflammatory cascades; quercetin blocks histamine release and inflammatory cytokines; resveratrol inhibits COX-1 and activates SIRT1. Conversely, excess omega-6 from vegetable oils, refined sugar, and processed meats directly upregulate inflammatory pathways through arachidonic acid and TNF-α production.
Evidence-Based Recipes
Ingredients
- 500g butternut squash, cubed
- 1 large sweet potato, cubed
- 1 large onion, diced
- 3 garlic cloves
- 2cm fresh turmeric, grated (or 2 tsp ground)
- 2cm fresh ginger, grated
- 1 tsp black pepper (essential for curcumin absorption)
- 400ml coconut milk
- 600ml vegetable stock
- 2 tbsp coconut oil
- Juice of 1 lime
- Salt to taste
- Pumpkin seeds and fresh cilantro to serve
Preparation
- Heat coconut oil in a large pot. Sauté onion 8 minutes. Add garlic, turmeric, ginger, and black pepper — cook 2 minutes.
- Add squash and sweet potato. Stir to coat in spices.
- Pour in stock and coconut milk. Bring to boil, then simmer 20 minutes until vegetables are tender.
- Blend until smooth. Add lime juice. Season.
- Serve topped with pumpkin seeds and fresh cilantro.
Ingredients
- 2 salmon fillets (wild-caught if possible)
- 100g mixed berries (blueberries, raspberries, blackberries)
- 40g walnuts, roughly chopped
- 100g arugula
- 50g baby spinach
- 2 tbsp extra-virgin olive oil
- 1 tbsp balsamic vinegar
- 1 tsp honey
- 1 tsp Dijon mustard
- Salt and pepper
Preparation
- Season salmon. Cook skin-side down in a hot oiled pan 4–5 minutes. Flip and cook 2 minutes. Rest 2 minutes.
- Whisk olive oil, vinegar, honey, and mustard into a dressing.
- Combine arugula and spinach in a bowl. Toss with dressing.
- Place salad on plates. Top with salmon, scattered berries, and walnuts.
What to Eat & What to Limit
Beneficial Foods
- Oily fish — salmon, mackerel, sardines (EPA/DHA)
- Extra-virgin olive oil (oleocanthal, polyphenols)
- Turmeric with black pepper (curcumin)
- Berries (anthocyanins, quercetin)
- Leafy greens (antioxidants, K1)
- Walnuts (ALA, polyphenols)
- Ginger (gingerols inhibit COX-2)
- Green tea (EGCG inhibits NF-κB)
- Brassica vegetables — broccoli, cabbage (sulforaphane)
- Beans and legumes (prebiotic, low glycemic)
Limit or Avoid
- Refined sugar and high-glycemic foods (AGEs, insulin spikes)
- Excess omega-6 oils — sunflower, corn, soybean (arachidonic acid cascade)
- Trans fats (strongly pro-inflammatory)
- Red and processed meat in excess (saturated fat, heme iron)
- Alcohol above 2 drinks/day
- Refined grains and ultra-processed foods
- Artificial trans-fatty acids
Red Wine Polyphenols: Anti-Inflammatory Evidence
Consistent moderate intake reduces CRP; excess acutely raises inflammatory markers
When Inflammation Requires Medical Investigation
Elevated CRP or other inflammatory markers without clear cause warrant investigation:
- CRP persistently above 10 mg/L without obvious infection — rule out autoimmune disease
- Joint swelling, stiffness, and fatigue together (possible inflammatory arthritis)
- Recurring skin rashes, fatigue, and sun sensitivity (possible lupus)
- Mouth ulcers, eye inflammation, and bowel symptoms (possible IBD)
- Unexplained weight loss, night sweats, and fatigue (requires thorough workup)
