I underlined the word processed because it’s important.
My guess is that you’re probably not eating fast-food everyday of your life but most people have no idea how processed much of their food really is.
You probably already know to stay away from trans fats.
Those are strongly linked to systemic chronic inflammation and are so bad for you that the Institute of Medicine recommends you simply keep trans fatty acid consumption as low as possible.
French fries are by no means the only culprit though.
Soybean, corn, peanut, and sunflower oils are examples of vegetable oils that are rich in omega-6 fats, which most Americans consume far too much of.
Too much omega-6 causes pathologic inflammation.
If your body has lost its ability to call off the pathologic inflammation when it’s not needed, you can run into problems, especially if you’re over 25 years old.
What keeps people under 25 from having to deal with pain and what makes them immune to arthritis?
