Most polyUnsats, and monoUnsats (like the ones in Nat. PB, flax) are good fats for ones intake of daily needs. Most saugage, once you do the math with calorie per gram with the grams of fat (and then consider the Sat. fat in it, which I believe ARE NOT GOOD), you learn fairly quickly it is HIGH. I stay away from polish saugage, unless there is a version of it that is more taylored to me goal, which I havent found yet. Omega-6 and 3's are generally good for you (flax and fish oils have it), but yes, if its coupled with far too much saturated fat, I would stay away from it.
I have taylored my diet where I virtually get no fat from animals (I know there is good clean steak, and pork, I just dont have in my diet for my owns reasons), with that said, I do eat clean baked chicken, fish (staple is fatty fish), and tend to favor chicken for two reasons (high protein, and virtually no carbs (like eating it before bed for an example). So I only get my fats from PLANTS (nuts, flax,etc). And has done fairly well. Does anyone know of a GOOD sausage, REALLY CLEAN and for real....low in fat?
