Is gammon ultra processed

[FrustatedAgain]

My son will only have ham sandwiches. I’m trying to think of ways to make that better. Is a joint of gammon that I boil at home myself still considered to be ultra processed?

I am no expert on this but isn't the idea of avoiding ultra-processed foods to avoid certain ingredients in them? I would therefore compare the ingredients list on a pack of pre-sliced ham with the ingredients on a joint of gammon you buy yourself, plus of course anything you add to that in cooking. My hunch is they would end up being very similar. I suppose he wouldn't eat roast pork or chicken instead? Or cheese, or hummus? (I sympathise, you'll have tried all this, I'm sure.)

My son (now 30 and extremely healthy) had a very limited list of things he would eat as a child. He usually had peanut butter sandwiches for lunch, for years on end. It's not ideal, but I took the view that it was better for him to eat something than nothing, and I used wholemeal bread and peanut butter made from just roasted peanuts, as far as possible. (He now eats virtually anything, so there is hope.)

It would be quite salty. You could soak before cooking.

I’d love to send peanut butter sandwiches to School.
Ate them all the time, myself, as a kid!

There is gammon available without nitrates or natural cure. That is what we buy from local Butcher, costs a bit more but it tastes like meat from the 80s.

Thanks, yes he is a fussy boy, a truly fussy child and there are a limited number of things he'll eat. Peanut butter is one of them, I know we can't send it in lunchboxes for good reason but it would really help if I could.
I've done the suggestion of reading the ingredients. I buy good quality ham and it does have more additives and even some E numbers listed on the ingredients. The gammon joints have less listed so I'll buy that from this weekend and pop it in the slow cooker on a Sunday. He will eat gammon. I'm also going to try and push chicken with him a bit more and see if he'll let me pop that in occasionally.
He eats too much processed food in his lunchbox daily so I really want to try and make a change where I can.
