In a new study conducted at the University of Haifa by Prof. Micah Leshem, no connection was found between salt consumption and thirst or increased drinking of water," Pub owners can reduce the amount of salt in their well snacks, without fearing a decrease in the amount of drinks consumed," said Prof. Leshem
Eating salty food does not necessarily increase the feeling of thirst, according to a new study conducted at the University of Haifa. "According to the concept that salt consumption increases thirst, the assumption was also born that as a result there is a fear of increased consumption of sugary drinks. However, our study did not find any support for this assumption," noted Prof. Micah Leshem from the Department of Psychology, who conducted the study.
According to the popular perception, consumption of salt will make us thirsty and drink more, to restore the balance of minerals in the body. According to Prof. Leshem, another assumption that is added to the first assumption is that because of the great feeling of thirst, and in light of the preference of many of us to consume drinks with a high caloric value - sugary or alcoholic drinks - the consumption of salty food actually also leads to an increase in calorie consumption and indirectly - to obesity.
However, according to Prof. Leshem, despite the feeling that it is "obvious" that salt increases drinking, this relationship has not been studied under conditions that simulate eating high-salt foods, such as salty appetizers. Therefore, in the current study, in which 58 students participated, the researcher wanted to test the effect of salt in solid food. The subjects arrived once every few days, after two hours in which they did not eat or drink anything but water and did not smoke. Every day they tasted nuts - once candied nuts, once salted and once without addition. They rated the degree of their thirst and after about two hours, during which they answered various questionnaires, they also received bottles of water, when everyone could drink as much as they wanted.
The main finding was that the degree of thirst and the amount of actual drinking after eating the salted nuts were not different from after the sweet or unsalted nuts. In order to further examine this possible connection, the researchers selected the 10 male and 10 female students who consumed the largest amounts of salt (4.4 g and 3.7 g of salt respectively) and asked to know if there was a connection between thirst and drinking among this small group, however No such connection is found here either. That is, even those who consumed large amounts of salt did not drink abnormally compared to the others.
Apart from the scientific implications regarding the balance of salts and fluids in our bodies and in our diet, Prof. Leshem concluded that "according to the findings, pub owners can lower the amount of salt in their well snacks, without compromising on the sale of drinks and the health of their customers".

really? The researchers should watch the video showing how a hunter makes a baboon show him where there is a water reservoir. Tip: This is of course related to the salt
In the past I didn't stop drinking after eating fish that was very salty...

I pointed out the specific deception regarding the salt and expanded my words on the whole mechanism of spices or "appetizers" (a well-known nutritional method of increasing appetite and thirst when eating or drinking).
Specifically regarding the salt, there are many ways to get rid of the feeling of excessive saltiness: for example, getting rid of the taste of saltiness by eating and not by drinking, each person chooses how to get rid of the taste in the way that suits them best. The preference to get rid of the salty taste by drinking is because drinking is the easiest to prepare (but many would prefer eating food to get rid of the salt load, especially if the salt is added as an appetizing spice to the main food).
In a more inclusive way (I said in a previous comment). The mechanism of eliminating flavors exists not only for salt but for almost any substance that is defined as a "spice". For example: vinegar or "pepper powder" or "garlic". If the spices are eaten separately from food or drink they leave a bad taste; Adding them to food is intended to stimulate the desire to eat (to eliminate the bad taste they create by swallowing the main food). Try eating a quarter of a teaspoon of "garlic" without any accompanying food or drink and you will immediately understand how bad it tastes and why it arouses the desire to eat when it is added as a spice. This is the case with all the spices.
Billions of people who add spices to increase appetite are worth more to me than psychologists who test 100 people. Just bullshit research.
Psychologists don't understand anything about drinking (just like they don't understand a thousand other phenomena that they "research"). I only mentioned the matter of the salt because here they were caught red-handed in the bluff.
More examples. Coca-Cola adds phosphoric acid to the Coca-Cola drink, exactly the same mechanism of increasing thirst by eliminating the bad taste through drinking. Most soft drinks add acidity to the drink to stimulate drinking in order to eliminate the sour taste (this includes the acidity of CO2 in carbonated drinks).

I didn't say for a moment that I accept or don't accept the research - I resented the fact that it was said "psychologists don't understand anything about drinking". In my view, an arrogant expression and not to the point.
But, in this case I think you are wrong. If I were to claim that "A" leads to "B", and I were to show in an experiment that there is a correlation between "A" and "B", then you are absolutely right that one should be careful with conclusions, and you are right that there should also be an explanation.
Here - the situation is different! They found that there is no correlation between "A" and "B" 🙂 That is, there is nothing to explain at all. The experiment disproves a correlation, so in my opinion, the conclusion is more convincing.
Miracles, don't be so quick to accept "scientific" conclusions, just because an "orderly" study was done.
The research presented in this article is very superficial.
I do not doubt the data found by the study, but the interpretation he gave them.
Research that wants to investigate a phenomenon in a serious and in-depth way conducts a large number of experiments, of different types, and from different angles.
Studies based only on statistics are very problematic. They supposedly show a connection between two phenomena, but do not collect any data that explains the mechanism that makes this connection possible.
Without an understanding of the mechanism behind a phenomenon, there is a very high chance that the examiner's question of the study will be wrong and misleading.
Hypothetical example: suppose that after eating salt, most people need a little water to wash the saltiness out of their mouths.
It is enough that the examiner's measure of thirst is chosen as "the amount of water the subjects drank" to give a distorted result, since it is not the amount of water that is relevant.

What did you base that on? Drinking is a concept of psychology, so who exactly is supposed to understand it?
There are many things we are sure are true, until proper research is done. For example - most of us think that salt raises blood pressure...
Psychologists understand nothing about drinking. They are experts in complicated questionnaires with the help of which you can prove that every strange claim of theirs is a true claim.
Anyone who eats something very salty needs to drink or eat to get rid of the bad feeling of high salinity.
It is possible to eliminate the bad feeling of saltiness also with the help of eating after the salty substance, (this is what the method of appetizers is based on). Other substances also require drinking or eating to eliminate the bad feeling of eating "spicy" or "bitter" substances, this is the method of adding spices to food.
Do your research by tomorrow, I have to drink after Doritos
