sausages and hotdogs are usually crappy meat leftovers and other animal tissue all grounded up and made into the sausage shape. plus all the preservatives like rodja said. you need to discover healthy meats/fish that you like. there are so many choices of uncooked fresh food you can make, why bother with this sausage crap. Chicken or turkey breasts, salmon filets, good cuts of steak, thats just to start off with. IF you want to be fit you will have invest time into buying and cooking raw food. Make eggs, meats, fruits and vegetables all a base of your diet and build up from there.
