Official medicine has been trying to persuade people not to eat “excessive amounts” of salt for almost 20 years, while others have contrary views. In fact, salt consumption seems to be a subject of passionate debate among medical and dietetics experts up to this day. As if there was no simple solution to the problem. But there is.
The issue last came up again because of the school canteens reform in 2016 in Hungary, where it gave rise to highly emotional arguments. The reform produced a rather interesting result: the saltshaker disappeared from the dining table and landed in the children’s pockets and bags. However, scientific solutions have not much to do with feelings and emotions as a rule. Now again, the key lies in the laws of nature.
Physicians and dietitians tend to think that “excessive” salt consumption leads to health problems like, for instance, high blood pressure, and this calls for the need to reduce the intake of salt. Widespread support for this view then helped shape the almost saltless Hungarian school meal.
But what is the truth? Is there a specified limit to salt intake? And does “excessive” salt consumption really cause elevated blood pressure?
Here are a few reliable arguments to answer the above questions:
There are also some further facts:
In addition, here is a very important fact, actually a simple biochemical and mathematical correlation:
Consequently, if we consume a larger amount a carbohydrates, then we will need more salt, that is our salt requirement will increase. In those cases salt is essential, that is, we will add more salt to our food. If, however, we eat less carbohydrate, then originally saltless food will even taste salty for us.
Therefore, whereas experts are engaged in ardent debates today as to the ideal daily intake of salt, science provides an exact and unambiguous answer.
Our salt balance is self-regulated. The requirement for sodium ions determines the physiological requirement of salt. As sodium is quickly secreted in the urine and through perspiration, our daily salt requirement may rapidly change. It mostly depends on the amount of carbohydrates we eat. We cannot define the recommended daily amount because it depends on the individual person and his dietary habit. However, it adjusts to our carbohydrate consumption in every case.
So it is senseless to set limits on the quantity of salt intake. Food containing the same amount of salt may taste too salty on Monday and insipid on Tuesday. The observations of our research team and feedback from our patients have perfectly verified the principles described above. Moreover, we can take observations ourselves.
To be sure, you may use as much salt as you wish, as it will have no harmful effects. It will not cause hypertension. People whose diet contains added carbohydrates, chiefly glucose and fructose, would want to eat more salt. However, the same foods would taste too salty for a person on lowcarb or zerocarb diet.
Nonetheless, once you vote on salt, try to use original rock salt that contains no anticaking agents or any other additives. An anticaking agent is in fact a cyanide compound and no one has adequately ever examined its physiological effect. Nor is KCl (potassium chloride), a mineral supplement health gurus consider good, innocent because of its effect to cause arrhythmia. Remember to avoid it. The whiter a salt, the purer it is. The different rock salts contain different ions, metals that may occasionally exert physiological effects and cause complaints.
Salt is most often present, aside from the dinner table, in processed meat products. Therefore, it is worth examining before we buy the smoked ham we chose that what kind salt they used in the curing process. Avoid products processed by the application of salt containing nitrites and/or nitrates. Nitrite and, indirectly, nitrates, too, may cause cancer.
