How salt changes food and affects our bodies

Salt is a wonderful mineral that mysteriously and intensely enhances the flavor, consistency and chemistry of our foods. Salt is always essential in the kitchen, but the amount of salt we should eat every day is also very important to human health.

Salt can be produced from salt mines or by exposing seawater to evaporation over salt fields. We use salt to prepare everyday foods and to replenish our minerals with minerals.

Our fondness for salt may in part stem from a biological need. Professor Russell Keast, a food scientist at Deakin University in Australia, said: “From a human health research perspective, we have studied and found that sodium concentrations are related to physiological health of the human body ''.

Sodium makes up half of every molecule of table salt, which works to keep our nervous systems and physical bodies functioning properly. At first humans found the compound to be rare, Keast said, which might explain why we like the flavor so much. Our original ancestors made sure they ate everything before they figured out how to taste it.

But the salt content in most of the diets is above the allowable level. Instead of consuming the right amount of salt, most of us eat too much salt because commercial foods produce high salt content in the ingredients that makes the dish delicious.

Because of the commercialization of food, people are currently using salt in excess of what it needs, which is harmful to health. Mr. Keast said that it is more difficult to get diners out of our high-salt diet than imagined, partly because we are by nature to prefer to eat more minerals. "It is a result of our habit that we do not have a solution yet," he said.

Control adequate salt levels in food

Salt helps improve the taste of food, besides it is also an essential ingredient for the body to function properly. In dishes, salt will help reduce bitterness and increase sweetness. This means that salt is very effective at directly affecting three of the five flavors we normally feel by mouth: sweet, bitter, salty, sour, and seasoning.

It is not clear how salt modifies the taste of foods, Keast said. Presumably, the change in taste affects the nerves, after taste senses all the compounds in each piece of food and relayed signals to our brain.

What's more impressive is that salt can alter the flavor of food from the inside, which is difficult to detect.

Participants in one study sampled a variety of broths, such as vegetarian broths. When the broth is added with salt, the eater perceives and savor the changed flavor but cannot determine where another flavor is.

Only when the amount of salt reaches a level that scientists call the "perception threshold" will people taste the so-called salinity. Mr. Keast said at that point, the attractiveness of the broth began to decline. A dish at the Goldylocks' salt level - not too much and not too little - is when the overall taste is at its best.

Food processing industry with salt

The salt content of each food is different (whether you feel it or not), there is a difference. This is why the sodium content in some products is surprisingly high. Foods made from whole grains, for example, easily incorporate high amounts of salt without spoiling taste. In the United States a
