It's really not all that unhealthy, depending on how you make it. In typical American size portions, it is an excessive amount of red meat for one sitting. We have it on our inpatient menu at the hospital I work at. Though the portions are not typical, the recipe is pretty standard but with less added salt.
I made it about a month ago, and it was a recipe that added in a bit of lentils to add in some more bulk/fiber/texture. It turned out pretty well. Wouldn’t be something I’d make a lot, but I’d certainly do it again
It's probably the same as with any kind of food. You can prepare it with good ingredients and it's fine, but when you buy that mass-produced shit, you now you are eating garbage.
I mean the only thing in the can is the tomato sauce.
You still have to provide your own ground beef, cook it up, and then add the sauce. But you can also make your own sloppy joe sauce with some tomato sauce from scratch. And you dont even need to use beef. Ground turkey or chicken, or even some lentils for a vegan version.
