Faster with Mediterranean
When I first started researching anti-inflammatory eating, I was overwhelmed by the lists. Superfoods, supplements, protocols — all promising results. What actually moved my CRP marker was simpler than I expected: a consistent rotation of fatty fish, extra virgin olive oil, leafy greens, and a few key spices. The power was in the combination and the consistency, not in finding some exotic ingredient I’d never heard of.

Why Food Is Your Most Powerful Anti-Inflammatory Tool

Chronic inflammation is driven primarily by what you eat, how you sleep, and how much stress you carry. Of these three, food is the most controllable — and on a keto Mediterranean approach, every meal becomes an opportunity to actively reduce inflammatory load rather than simply avoid adding to it.

The Key Mechanism

Refined carbohydrates trigger inflammatory cytokine release within 2 hours of consumption. Eliminating them removes the most frequent daily inflammatory driver. The Mediterranean foods listed below then actively reduce existing inflammation — through oleocanthal in olive oil, EPA and DHA in fatty fish, and curcumin in turmeric. You’re not just stopping the damage — you’re actively healing.

The combination of ketosis and anti-inflammatory Mediterranean ingredients works faster than either approach alone. Ketones reduce oxidative stress at the cellular level while Mediterranean polyphenols suppress inflammatory signalling pathways directly.

Fatty Fish — The Highest-Impact Category

If you could only make one dietary change for inflammation, it would be eating fatty fish 3–4 times per week. The EPA and DHA omega-3 fatty acids in fatty fish are the only nutrients that directly convert to resolvins — the molecules that actively switch off inflammatory signalling.

01

Sardines

More EPA + DHA per serving than salmon, far cheaper, shelf-stable in tins, and the easiest protein to add to any meal. The bones (soft and edible in tinned sardines) add significant calcium. One tin delivers approximately 1.5–2g of omega-3s.

✦ Priority frequency: 3–4× weekly. Best eaten straight from tin with olive oil, lemon, and herbs — zero cooking required.
02

Wild Salmon

The most familiar and versatile fatty fish. Wild-caught delivers significantly more omega-3s than farmed. Salmon also contains astaxanthin — the carotenoid that gives it its pink colour and acts as a powerful antioxidant that crosses the blood-brain barrier.

✦ Priority frequency: 2–3× weekly. Air fryer at 180°C for 8–10 minutes — pull at 57–60°C internal temperature.
03

Mackerel & Anchovies

Mackerel has one of the highest omega-3 contents of any commonly available fish. Anchovies — often dismissed as a pizza topping — are one of the most concentrated sources of EPA and DHA available. Both are significantly cheaper than salmon.

✦ Anchovies dissolve into sauces and dressings — a teaspoon of anchovy paste adds anti-inflammatory fat to any dish invisibly.

Oils and Fats — The Foundation

Avocados contribute monounsaturated fats and potassium — important on keto where electrolyte depletion can itself trigger inflammatory stress responses. Kalamata olives provide a concentrated source of hydroxytyrosol, one of the most bioavailable polyphenols in the Mediterranean diet.

Vegetables and Herbs

Leafy Greens — Unlimited

Spinach, arugula, kale, and Swiss chard are effectively unlimited on keto — extremely low in carbohydrates, high in magnesium (which keto depletes), and rich in vitamin K and folate which support methylation and inflammatory regulation.

Cruciferous Vegetables

Broccoli, cauliflower, and Brussels sprouts contain sulforaphane — a compound that activates Nrf2, the master regulator of the body’s antioxidant defence system. This is the mechanism that makes cruciferous vegetables genuinely anti-inflammatory rather than merely neutral.

The Spice Stack That Changes Everything

Turmeric + black pepper is non-negotiable. Curcumin (the active compound in turmeric) is poorly absorbed on its own — piperine in black pepper increases bioavailability by up to 2000%. Without black pepper, you’re getting roughly 3% of the curcumin. Together, it’s a meaningful NF-κB inhibitor that reduces inflammatory gene expression.

Greek oregano contains carvacrol — a compound with antimicrobial and anti-inflammatory properties significantly stronger than standard Italian oregano. Use generously on everything.

Foods to Avoid for Maximum Benefit

Anti-inflammatory eating is as much about removal as addition. These foods drive the cytokine production you’re trying to reduce.

❌ Seed Oils

  • Canola oil
  • Soybean oil
  • Sunflower oil
  • Corn oil
  • Vegetable oil blends

❌ Refined Carbs

  • Bread and pasta
  • White rice
  • Sugar in all forms
  • Crackers and cereals
  • Processed keto bars

❌ Processed Meat

  • Deli meats with nitrates
  • Factory-farmed meat
  • Breaded or fried fish
  • Sausages with additives
  • Smoked meats daily

❌ Other Drivers

  • Alcohol
  • Artificial sweeteners
  • Low-quality dairy
  • Margarine
  • Hydrogenated fats

Daily Meal Ideas

Breakfast

  • Spinach and mushroom omelette in EVOO, topped with avocado and oregano
  • Smoked salmon with cream cheese, capers, and arugula
  • Chia pudding with coconut milk, walnuts, and a drizzle of olive oil

Lunch

  • Large arugula salad with sardines, Kalamata olives, and EVOO dressing
  • Cauliflower rice bowl with mackerel, roasted vegetables, and turmeric
  • Bone broth with leafy greens, garlic, and ginger

Dinner

  • Wild salmon with roasted broccoli and cauliflower mash finished with EVOO
  • Grass-fed beef with bok choy, ginger, and rosemary
  • Sheet pan sardines with zucchini, cherry tomatoes, oregano, and lemon

What to Expect — Week by Week

Weeks 1–2
  • Reduced bloating
  • Improved mental clarity
  • Better sleep quality
  • Less afternoon energy crash
Weeks 3–4
  • Anxiety beginning to quieten
  • Joint pain and stiffness reducing
  • Brain fog lifting noticeably
  • Skin beginning to clear
Weeks 8–12
  • CRP measurably lower
  • Stable energy all day
  • Improved cardiovascular markers
  • Mood and motivation improved
Consistency matters more than perfection. You don’t need all 15 foods every day. Focus on variety throughout the week — fatty fish 3–4 times, EVOO daily, leafy greens at every meal, and turmeric with black pepper as often as possible. That rotation, sustained for 8–12 weeks, is what moves the markers.
