It is not true.
To make it cook faster
yes the salt raises the temperature to boil faster
Since salt is an electrolyte, yes, it does cook faster, but it's not that much of a difference.
Water is a bad conductor of heat.salt has a slightly high boiling point
It takes to long to get the noodles softened.
There is the opinion that cooking would be faster; I did not notice this effect.
Spaghetti will cook faster in salt water compared to plain water because the salt increases the boiling point of the water, allowing it to reach a higher temperature more quickly. This results in faster cooking times for the pasta.
Salt
Adding salt to beans can help them cook faster because it can increase the temperature at which the beans soften. Salt can also enhance the beans' flavor and help maintain their structure during cooking. However, it's important to add salt at the right time; adding it too early can toughen the beans' skin, so it's often recommended to add it after the beans have started to soften.
