Mrs. Dash is a great brand for no-salt spice mixes (plus they make a good marinade). Just be sure to read the labels on EVERYTHING - products marked as "healthy heart" usually have high sodium. Also, some products change ingredients from time to time so something you thought was safe can be too high. I also learned the hard way that even fresh products, like raw chicken, can have salt water injected, so you have to read even those items. You can google low salt or low sodium recipes and find alot of good sites for low sodium products and recipes. Good luck! It takes some time to get started but once you do it's not so hard. Also your taste buds will adjust (tell your friend to hang in there) and soon he will be happy to eat foods w/less sodium.
One other thing - eating out is brutal - most foods in America are heavily salted. I go to the websites for restaurants whenever available and look up nutritional info. Then I write down one or two choices from the restaurants I most likely might visit and keep it in my purse. Then when I unexpectedly end up in a restaurant I can eat something that is healthy - low calorie/low sodium and not make a big deal of it in front anyone else.
