Hi Penny,
My husband recently had to go on low salt diet. I've had to reduce the salt in all his favorite foods. At first he really complained about the lack of taste, but after 3 weeks, his brain/perception finally changed.
So, as for his favorite BBQ sauce. I eliminated any added salt. Then all the products I bought, I found low salt or no salt added. So, for the katsup, I went to the diabetic section and natural foods section and found a low sugar (for me) and low salt for him. Same thing with tomato sauce, Worcestershire sauce, etc.
I am amazed at how many grams of salt I eliminated from the BBQ sauces original recipe. And like I said, after a few weeks, he still loves his favorite BBQ sauce recipe
I hope this helps a bit.
