You're correct though. The term is very unclear and doesn't help people. Generally speaking the refinement process of carbohydrates and sugars means glucose hits your blood stream faster and increases inflammation. (These refined carbs are also more addictive, reduce insulin sensitivity over time and lead to obesity)
For an anti inflammatory diet think raw foods, whole grains, high fiber, quality protein, low amounts of complex sugars, NO refined sugars. Stay low on the glycemic index.
Basically, make your body do a little work to metabolize calories. No easy street.
Also don't fry with vegetable oils. Consume plenty of olive oil and fish oil.
