Dousing every meal in salt might make food tastier, but all that extra sodium is eventually going to raise your blood pressure—giving you bigger problems than bland food. So researchers in Japan have built a prototype electric fork that uses electrical stimulation to simulate the taste of salt.
Does it have an MSG setting? 😉
According to most science, with some exceptions for people with a hypersensitivity, the salt & blood pressure thing isn’t true: http://www.scientificamerican.com/article/its-time-to-end-the-war-on-salt/
The other thing to consider about table salt is the amount of iodine that’s in it, as a preventative measure against iodine deficiency and gout. That’s why some recipes specifically call for other types of salt, but as you can see – table salt should not be avoided entirely.
