What's wrong with repetitive adrenal whipping is that adrenal fortitude is variable; many people's adrenals eventually fail to respond to the prod of salt and the body begins to suffer from a lack of adrenal hormones. Often those inheriting weak adrenals manifest semi-failure in childhood. The consequence is that ordinary, irritating substances begin causing severe irritation. The person becomes allergic to pollen, dust, foods, animal danders, etc. We see asthma, hay fever, sinusitis, etc. Though one can then discover specific allergens and try to remove them from the environment or diet, often this case can be solved far more easily by complete withdrawal from all salt. This rests the adrenals and they may recover their full function; almost certainly their function will improve. The asthma, allergies and etc., gradually vanish. Most of us don't need to eat salt as a nutrient. There's enough sodium in one dill pickle to run a human body for a year. There's enough natural sodium in many types of vegetables to supply normal needs without using table salt. Perhaps athletes or other hard working people in the tropics eating deficient food grown on leached-out depleted soils, people that sweat buckets day after day may need a little extra sodium. Perhaps. Not having practiced in the humid tropics myself, I have no definitive answer about this. Unfortunately, the average American is entirely addicted to salt and thinks food tastes lousy without it. To please the average consumer, almost all prepared foods contain far too much salt for someone suffering from exhausted adrenals. Interestingly, Canadians do not like their foods nearly as salty as Americans, and prepared foods like soups and the like in cans and packages that look just like the ones in American supermarkets (though with French on the back panel) have to be reformulated for our northern neighbors. I've observed that Canadians are generally healthier than Americans in many respects. We would all be far better off consuming no salt at all. Those with allergies or asthma should completely eliminate it for a month or two and discover if that simple step doesn't pretty much cure them. The trouble is that bakery bread is routinely two percent salt by weight. Cheese is equally salted or even more so. Canned and frozen prepared food products are all heavily salted. Restaurant meals are always highly salted in the kitchen. If you want to avoid salt you almost have to prepare everything yourself, bake your own bread, abstain from cheese (though there are unsalted cheeses but even I don't like the flavor of these), and abstain from restaurants. My family has managed to eliminate all salt from our own kitchen except for that in cheese, and we eat cheese rather moderately.
