I watched this show the other night and was surprised that hot dogs can bring on a lot of illnesses .... The large corps want to hide from you and went to great lengths to do so ... becouse of the Potassium nitrate... something that makes them pink ...and more appetizing ... and I really only like a few brands of hot dogs ... but so many eat them becouse the easy to make and pick up for many people or large family's ... now I have had only one experience with someone ...who ate hotdogs with every meal ... and until the person stopped and slowed down on them is when they passed ... they could have have many issues but never saw any... and they lived a really long life ... maybe something in our gens that makes a difference ...
but all kinds of info on this ...

there are things like preservatives in just about ANYTHING that you buy nowadays that arent good for you,but for the most part,these shows,like 'the doctors',and 'dr oz' like you are talking about that feel the need to tell you just how dangerous these things are are nothing but fearmongers that are trying to frighten you,so that they can manipulate you into watching their show,and give them better ratings,which makes their show more profitable for them.
it is the television equivalent of 'clickbait'!
there is stuff that is not entirely healthy in just about EVERYTHING that you eat,but people eat them everyday,and they havent died,or gotten sick!
there are things like germs,and bacteria in just about everything that you eat,too,that arent entirely healthy for you,too[but,A LOT of it that IS healthy for you!!!] ,but unless your immune system is compromised,you are safe,and nothing bad is going to happen to you,unless you get some of the REAL BAD ones,like E coli,or botulism,which is actually pretty rare,unless you REALLY ignore basic food safety.
so,stop obsessing over stuff like this,and just enjoy eating what you want to eat!!
