8. Refined Carbs
Refined white flour is a product that takes healthy whole grain and strips every bit of nutritional value from it. The result is a product that increases harmful cytokines in your blood stream; cytokines in turn spark (you guessed it) inflammation. White flour is also high on the glycemic index and will spike your blood sugar.
White flour is really hard to avoid because it is in hundreds of products. However, you may want to reduce your consumption as much as possible by choosing whole grain bread and occasionally replacing flour tortillas with lettuce and pasta with shredded zucchini or squash.
