21-Day Anti-Inflammatory Diet: Foods to Eat

For your 21-day anti-inflammatory diet, start with vegetables and fruit in a range of colors, such as leafy greens, broccoli, tomatoes, berries, and citrus, then add whole grains like oats, brown rice, or quinoa. A practical plate is half vegetables, one quarter whole grains, and one quarter protein, with fruit alongside breakfast or as a snack.

Rotate beans, lentils, tofu, eggs, and fish through your meals; salmon, sardines, and trout are useful choices when you eat seafood, while walnuts, chia seeds, and ground flaxseed offer plant-based variety. Use olive oil for cooking or dressing, and add foods such as avocado, nuts, or seeds in portions that fit your appetite and energy needs.

Instead of building meals around refined grains, processed meats, or sugary snacks, try oatmeal with berries and walnuts, a lentil-and-vegetable bowl, or fish with roasted vegetables and brown rice. Flavor meals with herbs, garlic, ginger, and spices, and choose water or unsweetened tea more often than sweetened drinks without feeling that every meal must be perfect.

For the first week, stock a few versatile staples—frozen vegetables, canned beans, oats, olive oil, and fruit—so you can assemble meals even when you have little time. During weeks two and three, repeat combinations you enjoy and vary the produce and protein; our Anti-Inflammatory Eating for Radiant Skin ebook is a companion if you’d like to explore this approach with a skin-focused lens.

You do not need to eat every food on an anti-inflammatory list: choose options you tolerate, can afford, and enjoy, including frozen or canned produce when fresh choices are inconvenient. If you have a food allergy, a medical condition, or a prescribed diet, keep those requirements first and ask your clinician or registered dietitian before making major changes; for more meal ideas, read our full anti-inflammatory diet article.
