A viewer asks: “I eat a single large hot dog once or twice a week as a source of protein. It makes a quick, easy-to-cook meal when my wife is busy, but I worry about eating low quality meat containing preservatives. Is this hazardous to my health, and if so, why? Would it be of significant benefit to my health to avoid them by substituting eggs and/or bacon?”

As you are well aware, hot dogs do have the deficiencies you noted, so it is unwise to have that in the diet, certainly as a regular feature, even somewhat sparingly. There is no other way to describe it. You will not get a rationalization from us as you are asking about the hazards and those are real. Although it won't kill you in the near term, it adds damage and this you do not need given the many other sources of toxic chemicals in food. Other sources of fresh protein like eggs or bacon would be far preferable.
