Slim Jim's do contain some good protein so in moderation the Slim Jim is healthy to eat.
However Slim Jim's are not the healthiest and don't contain a whole lot of protein but you do get some protein from the Slim Jim's.
However Slim Jim's are also high in fat and sodium content so they are not the healthiest.
The skin on the Slim Jim is edible and you do not have to pee the Slim Jim's.
I've eaten Slim Jim's for years now and never once have I peeled the Slim Jim before eating them.
I just remove the Slim Jim from the package and eat it.
You could peel the skin off the Slim Jim if you want too but it's edible and there's no need to or requirement to peel the Slim Jim before eating it.
Just enjoy the Slim Jim as is as the skin on them are just as enjoyable.
Slim Jim's are not the healthiest snack but they are healthier than other snacks.
If you need to watch your weight then also don't eat too many Slim Jim's as they could increase your weight.
