An anti-inflammatory way of eating is mostly a familiar healthy pattern: plenty of vegetables, fruit, beans, whole grains, nuts, olive oil and fatty fish, with fewer refined carbohydrates, sugary drinks, fried foods and processed meats. No single “superfood” switches inflammation off. What matters is the overall pattern you eat most days, over months and years.
What inflammation is, and why diet matters
Inflammation is your immune system’s normal response to injury or infection. Short-term (acute) inflammation, like the swelling around a cut, helps you heal. The problem is low-grade inflammation that lingers. Harvard Health notes that chronic inflammation is associated with heart disease, diabetes, cancer, arthritis and bowel diseases, and that carrying excess weight can keep the body in a state of inflammation longer.
Food is one of the factors you can influence every day, alongside activity, sleep, stress and not smoking. Skipping alcohol also supports these health and weight goals.
Foods to eat more often
Harvard Health’s list of anti-inflammatory foods includes tomatoes, olive oil, leafy greens such as spinach, kale and collards, nuts like almonds and walnuts, fatty fish like salmon, mackerel, tuna and sardines, and fruits such as strawberries, blueberries, cherries and oranges. Here is how to use those and similar foods.
Vegetables and fruit
Colourful produce provides antioxidants and polyphenols, protective plant compounds. Aim for variety: dark leafy greens, tomatoes, peppers, broccoli, carrots, beets, berries, cherries, oranges and apples. Frozen and canned (without added sugar or salt) count too.
Beans, lentils and whole grains
Beans, lentils, chickpeas, oats, barley, brown rice and whole wheat are rich in fibre and help replace refined carbohydrates. If you want more plant-based meals, our guide to a plant-based diet is a good next step.
Healthy fats
- Extra virgin olive oil for cooking, roasting and salad dressings.
- Nuts and seeds, a small handful a day: walnuts, almonds, chia, ground flax.
- Avocado on toast, in salads or blended into dressings.
Fatty fish and other omega-3 sources
The NIH Office of Dietary Supplements lists fish and seafood such as salmon, mackerel, tuna, herring and sardines as the main sources of the omega-3s EPA and DHA. Plant sources of the omega-3 ALA include flaxseed, chia seeds, walnuts and canola and soybean oils. Including fish regularly is a practical way to get them; if you do not eat fish, use the plant sources often.
Herbs and spices
Turmeric, ginger, garlic, cinnamon, rosemary and oregano are an easy way to add flavour without extra salt, sugar or fat. Turmeric gets a lot of attention, but using it in cooking is a flavour choice, not a treatment. Talk to your doctor before taking turmeric or other supplements, especially if you take medication.
Drinks
Water is the best everyday choice. Sparkling water with citrus, milk or a fortified soy beverage, and herbal teas are good alternatives. Replacing pop and other sugar-sweetened drinks is one of the most useful changes you can make.
Cocoa, in moderation
Cocoa contains plant compounds called flavonoids. If you enjoy chocolate, a small square of dark chocolate or a mug of hot chocolate made with milk and real cocoa can fit into the pattern. Keep portions small because most chocolate is also high in sugar and fat.
Foods to limit
The same Harvard Health article suggests limiting these as much as possible:
- Refined carbohydrates such as white bread and pastries
- French fries and other fried foods
- Pop and other sugar-sweetened drinks
- Red meat (burgers, steaks) and processed meat (hot dogs, sausage)
- Margarine, shortening and lard
“Limit” does not mean “never.” Think about what you eat most often. Our tips on how to reduce processed foods can help with this side of the plate.
Two proven patterns to follow
You do not need a special “anti-inflammatory diet” plan. Two well-studied patterns already fit:
| Pattern | Core idea |
|---|---|
| Mediterranean-style eating | Vegetables, fruit, whole grains, legumes, nuts, olive oil as the main fat, fish often, less red meat and sweets |
| DASH (Dietary Approaches to Stop Hypertension) | Vegetables, fruit, whole grains, low-fat dairy, lean protein, nuts and beans, with less sodium, added sugar and saturated fat |
Harvard Health points to the Mediterranean diet as a pattern that closely follows anti-inflammatory eating. A plate built mostly of vegetables and fruit, with whole grains and protein foods filling the rest, fits well too.
A sample anti-inflammatory day
- Breakfast: Oats with blueberries, ground flax and a few walnuts; a glass of milk.
- Lunch: Big salad with spinach, tomatoes, chickpeas, peppers, olive oil and lemon dressing; whole grain bread.
- Snack: An orange and a small handful of almonds.
- Dinner: Baked salmon with garlic and herbs, roasted broccoli and sweet potato.
- Evening: Plain yogurt with cherries, or a mug of peppermint or ginger herbal tea.
Making it practical
- Change one meal at a time. Start with breakfast or lunch rather than overhauling everything.
- Keep staples on hand: canned beans, frozen berries and vegetables, oats, canned salmon or sardines, olive oil, nuts.
- Cook more often. Home cooking gives you control over oil, salt and sugar.
- Roast a tray of vegetables twice a week to add to meals.
- Swap, don’t just remove: sparkling water for pop, whole grain bread for white, nuts for chips.
Eating this way on a budget
Anti-inflammatory eating does not require expensive specialty products. Some of the best choices are among the cheapest in the store:
- Dried or canned beans, lentils and chickpeas
- Large-flake oats, brown rice and barley bought in bulk
- Frozen berries, spinach and mixed vegetables, which keep well and reduce waste
- Canned salmon, sardines or light tuna in place of fresh fish
- Carrots, cabbage, onions, sweet potatoes and apples, which are often affordable year round in Canada
- Store-brand olive or canola oil and bulk seeds such as ground flax
Buying produce in season and planning meals around what you already have also keeps costs down.
When to check with a professional
Diet supports long-term health, but it is not a treatment for inflammatory conditions such as rheumatoid arthritis, inflammatory bowel disease or lupus. If you have ongoing joint pain, swelling, digestive symptoms or fatigue, see your doctor. Check with your doctor or pharmacist before starting supplements such as fish oil or turmeric, particularly if you take blood thinners or other medication.
Key takeaways
- Focus on the overall pattern, not single superfoods.
- Eat more vegetables, fruit, beans, whole grains, nuts, olive oil and fatty fish.
- Limit refined carbs, sugary drinks, fried foods and processed meats.
- Choose water, milk and herbal teas; skip alcohol and pop.
- Make one swap at a time and keep healthy staples stocked.
FAQ
How quickly will I notice a difference?
There is no set timeline. Many people notice more steady energy within a few weeks of eating more whole foods, but the main benefits are long term.
Do I need to avoid nightshades or gluten?
Not unless you have a diagnosed condition or a clear reaction. Tomatoes are on Harvard Health’s anti-inflammatory list, and whole grains are part of both the Mediterranean and DASH patterns.
