My 80 year old grandpaw was told to cut down on his salt intake. We bought the no-salt substitute because he would not cut down on the amount of salt he used. His taste buds are not working correctly because he can not tell the difference. If you have ever tried it you knoe what I mean. Anyway, someone told me before the salt substitute caused some people problems. I don't know if it was just a few people or many. If anyone knows anything about this please let me know. Thank you

This problem is a simple fix. Take the salt away completely. He will eat when he is hungry enough.
