I agree. In general these meats can be full of hidden 'nasties'. But not all.

In my area the deli section of the large supermarkets keep a folder behind the counter which lists the nutritional analysis for all of the deli meats. It is updated each week.

Staff are happy for me to look at the folder.

Although one was a bit surprised when she said

"If its for a diet, we have the low fat meats marked".

and I replied

"Yes it is for a diet, now give me 1/2 a kilogram of that Salami and a kilogram of that bacon"
