The sodium levels reported on the label are higher on kosher chickens than non-kosher chickens. I presume the same is true of turkey, and I presume the same is true of brined vs non-brined birds. I'm not sure I would call the sodium levels in kosher/brined birds "extreme". It might be on the order of twice as much sodium, though, as you'll see below much of the extra sodium is in the skin. Also, when you use a kosher/brined chicken, you can probably dial back the salt you add during or after the cooking process.
I am not on a reduced sodium diet, so I don't worry about the extra salt from kosher and brined foods. The primary source of sodium in the average diet is from processed foods. I don't eat much processed foods. So I tend not to worry about the extra salt from brined/cured/koshered meats.
According to a two-decade old study in the Journal of Food Quality:
Salt content in the breast, thigh and skin was determined in chickens which had been kosher-processed with different salting times, quantities and different numbers of rinses and after cooking. Significant differences in the salt content were obtained after 1.5 h of salting. Salt quantity significantly affected only the thigh and skin. Rinsings had no effect in reducing salt content in the breast and thigh. Cooking did not reduce the salt content of the chicken except in the skin. The salt treatments used in this study, which were similar to those used in commercial kosher dressing plants, did not increase uptake of water.
I haven't looked for more recent studies. But if you are looking for a way to eat a kosher chicken and reduce the salt content, I'd skip the skin.
