Refined carbohydrates
White flour products (breads, rolls, crackers) white rice, white potatoes (instant mashed potatoes, or French fries) and many cereals are refined carbohydrates. According to Scientific American, processed carbohydrates may trump fats as the main driver of escalating rates of obesity and other chronic conditions. These high-glycemic index foods fuel the production of advanced glycation end (AGE) products that stimulate inflammation.
