The science
You don't need to avoid these forever. The data is clearest on chronic high consumption: daily soda, frequent ultra-processed meals, refined carbs at every meal. Occasional indulgence has minimal long-term impact for most people. Pattern matters more than any single food.

Frequently asked
What is the most inflammatory food?
Highly processed foods loaded with refined seed oils, added sugar, and chemical preservatives consistently rank worst. Sugary drinks (soda, energy drinks) hit the body acutely with both refined sugar and minimal nutritional offset.
Are eggs inflammatory?
For most people, eggs are neutral to mildly anti-inflammatory thanks to choline and antioxidants in the yolk. People with egg sensitivity or autoimmune conditions may react differently. Quality matters: pasture-raised eggs contain more omega-3s.
Is dairy inflammatory?
Mixed evidence. Full-fat fermented dairy (yogurt, kefir, aged cheese) tends to be neutral or anti-inflammatory in trials. Conventional milk and processed dairy products show mild inflammatory effects in some studies, especially in people with lactose intolerance.
