The National High Blood Pressure Education Programs recommends that healthy adults limit sodium to 2400 mg of sodium a day, well above survival level. In addition, we are programmed to consume salt. Our taste buds are coated with salt-seeking cells, and we have a physical craving for salt when our bodies run low on the mineral. So, cutting back isn't necessarily easy. But it's quite manageable.
Most people adjust to much less salt in a month or so.
A starting point towards moderation is to plan meals around foods that contain no more than 200 mg of sodium per serving. Read the food labels. Of course, decrease the amount of salt you add to food. As a substitute, try adding some tang to your food. A few drops of lemon juice boosts flavor as does a little vinegar, pepper and other herbs and spices.
