Processed foods contain a lot of ingredients that cause inflammation. One of the worst are trans-fats or partially hydrogenated oils. Partially hydrogenated oils are known to cause systemic inflammation and contribute to dozens of diseases from heart disease to cancers.
Read labels carefully as even a tiny bit is bad for you. Trans-fats are used to make food shelf stable, so you’ll find them in breads, baked goods, snacks like potato chips or microwave popcorn, fried food, refrigerator dough, nondairy creamer and margarine.
