It is funny how habits can change. I was a complete sucker for the “you can’t eat just one” advertisement. Put that stuff in front of me and I would not stop till it was over. Frankly, and I should be ashamed, I would just ask for more once it was over. It did not really matter what I was eating; it was the salt I was craving. So the advertisement is really alluring your craving for salt, not the product itself (just so you know). Today, if I taste something that is excessively salty, it feels bitter and undigestible. It is just a function of how you train your body.
So why are salty foods so addictive? The reasons could be many. For starters, in some cases, it could be that you are genuinely salt deprived. If you are reading this, you are likely to be eating well over the recommended 2200 mg a day or 1500 mg if you are over 50. Other reasons include a slow adrenal system that is not functioning well. This is a outcome of a stress filled environment. You could also be dehydrated and instead of drinking liquids you are craving salt. You could also missing other trace minerals like zinc or magnesium. You are then trying to compensate by eating salt. Finally, of course, you are jut habituated to the evening salty snack and like with everything else, your body now craves the kick at 5 pm. It is almost amazing but just short of 5 pm, your body will send a signal reminding you that it is due a treat at the appointed hour. It is the power of habit.
The solutions are fairly simple. If it is a habit, just simply stop. It will take a few days but you will lose interest. If you are deficient, get yourself tested and make up for what you are truly missing. Soon, you will not be able to swallow even one.
