Electric Fork Simulates a Salty Flavor By Shocking Your Tongue (med.news.am)

An anonymous reader writes: It's common knowledge that excess sodium can be detrimental to one's health. So researchers in Japan have built a prototype electric fork that uses electrical stimulation to stimulate the taste of salt. The battery-powered fork was engineered and designed at the University of Tokyo's Rekimoto Lab. It features a conductive handle that completes a circuit when the tines make contact with a diner's tongue, electrically stimulating their taste buds. The prototype fork, which was built from just $18 worth of electronics, creates a sensation of both salty and sour, and has adjustable levels of stimulation.

That not enough sodium in your diet can be detrimental to one's health.
And more importantly, not enough Iodine, depending on location, can be pretty bad also.

Bring on the Iodised salt!

Come on people, is it that complicated? everything in moderation, and a well rounded and balanced diet?

Of course, if they can invent a Chocolate fork... I suspect they will do well.

Walk into any building that sells food on this planet and ask where the low-sodium-soy-free-non-MSG-no-additives-no-preservatives-no-growth-hormones-no-HFCS isle is.

You don't even have to ask. Just use some common sense.

Start with the fresh produce department, where the bulk of what you should be eating should be coming from anyway.

Rice of all sorts, quinoa, wheat, oats and other grains are also readily available and contain none of the things you listed, so you can get some variety in your carbohydrates if you're tired of potatoes and yams.

For protein, most stores will have at least half a dozen different types of dried beans. If you don't want to eat a vegetarian diet, it's not hard to find meat and eggs produced without growth hormones, antibiotics and so forth.

In other words, the only reason you're stuck with all the stuff you've listed in your food is because you're choosing to buy products that contain all that stuff. Buy the ingredients and cook your own food and you get to choose what goes into it.

when I was a kid I wore braces. I also tested batteries with my tongue. One day I decided to connect a 9V battery (the one with the poles side by side) with my braces, to see what will happen. One pole on the upper side, the other on the bottom. There was a big shock, my field of vision became bright white for a split second, and I never tested batteries with any part of my face ever again.

ahem

Full Definition of electrocute
        transitive verb
      1 : to execute (a criminal) by electricity
      2 : to kill by electric shock

Notice that the definition of electrocute involves dying? When you say "mild electrocution", you're saying "mildly dead", which doesn't really make a lot of sense.

You're welcome to use the word as you want, of course (that's one of the fundamental things that makes English a living language) but when someone else is using the word, you need to be aware of the dictionary meaning of the word or communication suffers.

That having been said, electricity takes the path of least resistance. The only way the path between the tines of the fork will be through your heart or the nerves that drive your heart will be if the fork has been stabbed into your heart or your spine or, I suppose, just the right bit of your brain. In all three cases, you have much bigger and more lethal problems than the minuscule amount of current between the tines of the fork.

Common Knowledge is wrong

ISTR hearing about new research showing that the amount of salt in your diet has little to no effect on coronary heart disease.

While we're on the subject, the amount of fat in your diet has been shown to have no effect on blood cholesterol levels.

Not that I'm suggesting you consume salt by the bucketful or anything.

Look up super capacitors.

Argh! Supercapacitors are special because of their resistance to leakage and a high energy density. They actually have a lower voltage so they discharge slower, are heavier AND more expensive than regular electrolytic or ceramic capacitors making them exactly the WRONG choice for the purpose of electrocuting someone based on every possible consideration. What you want is an electrolytic capacitor in series with the power supply and a pull-up resistor set in parallel with the resistor going to ground. Go back to the eighth grade you AC retard!
