Yes, it is true. There are a lot of other things about nitrites that aren't so great either. They cause headaches. The headache that your child gets that is blamed on being in the sun at the ballgame is really due to the hotdog they ate. Hot dogs also contain a lot of sodium and some have as much as 50 percent of calories from fat.
Hot dogs are the number one cause of choking deaths in children.
That is another good reason to avoid hot dogs. I don't think sub sandwiches and cookies are nutritious yet they serve it as an option. It is absolutely disgraceful. The Department of Agriculture has used the school lunch program as a dumping ground for low fiber, high sodium and high fat foods. The lunch program contradicts what the children are being taught in their classes.
