Use fresh, rather than packaged, meats. Fresh cuts of beef, chicken or pork contain natural sodium, but the content is still much less than the hidden extra sodium added during processing in products like bacon or ham. If a food item keeps well in the fridge for days or weeks, that’s a tip off that the sodium content is too high. This was the tip I found from https://www.kidney.org/news/ekidney/june10/Salt_june10.
I am going to try to cut bacon totally out of my diet and really look at any other processed meats I use (especially sandwich meat). I already looked at one the other day and it had so much!
