Everything you love about potato chips comes down to the combination of three basic flavors: potatoes, oil and salt. But as health concerns about sodium continue to rise, food manufacturers are scrambling to figure out how to reduce it -- without sacrificing taste.
Research and development executives at PepsiCo, the company that owns Frito-Lay, think they have the answer. And it's a solution only a chemist could love: They're going to change the basic shape of salt.
A quick high-school science class recap: Salt molecules are basic cubes, which means it takes each crystal awhile to break down in your mouth when you're chomping on chips.
"Early on in our research, it became apparent that the majority of salt on a snack doesn't even have time to dissolve in your saliva because you swallow it so rapidly," Mehmood Khan, senior vice president, chief scientific officer and a former Mayo Clinic endocrinologist, said during a recent PepsiCo investor presentation.
A Wall Street Journal piece reported only about 20 percent of the salt on a potato chip dissolves on the tongue, while the remaining 80 percent is swallowed without contributing to taste. The solution? Use crystal chemistry to re-jigger the shape of salt to create more surface area. That way, no un-tasted salt ends up in your digestive system. PepsiCo thinks it can cut up to 25 percent of the sodium in their chips using this technique.
If messing with nature makes you a little nervous (remember Olestra?), you can breathe easier knowing that Brits have been consuming a similarly altered salt for three years with no reported problems. And you have some time to get used to the idea -- chips using this technology aren't expected on shelves for at least a year.

How much of that has actually worked?
The NLEA which mandates Nutrition Facts on many foods is from the 1990s... it was SUPPOSED to save lives by showing people how many calories were in foods so people could make healthy choices. Back in the 1990s, about 20% of the population was obese; today, more than 33% of the American population is obese.
There seem to me to be MANY government programs that are well meaning, but have done NOTHING to improve the health and wellness of the population at large (and no pun intended there... well... maybe...). This salt program will end up being the same; lots of fanfare, and it does nothing for the public.
Especially since the salt shaker will still be on the table...

So yes, eliminating too much salt from the diet can do you some good if you have blood pressure issues.
This is not a "new thing" but has been known as an issue for many years. People with high BP have always been told to lower the amount of salt in their diets. It does not mean to eliminate all salt, just to reduce it. I have been able to do that with every recipe I make and still have them taste good.
Lays already has a "lightly salted" chip that tastes far better than the regular ones anyway. You can actually taste the fact that they are made out of potato instead of getting a mouthful of salt.
4-29-2010 @10:50AM Firehaven said... Susan, What tastes better is always a matter of personal preference, so you cannot categorically say that something tastes better...maybe it will to you...but not necessarily to someone else...
4-29-2010 @11:12AM Eileen Bettenhausen said... If I wanted to taste all that salt I would just shake the salt shaker into my mouth. I want chips with almost no salt, They taste much better.
4-29-2010 @12:35PM Tom said... Why not switch to a product called "No Salt" I believe it has potassium chloride, but no sodium. I use it and use less of it because it tastes more salty
4-29-2010 @1:17PM Al Schrader said... I already invented an even better way to put salt on chips. It's powdered salt, not granulated.
It all dissolves instantly as soon as it hit your tongue....alfredschrader@aol.com
4-29-2010 @3:54PM Harvey said... It is impossible to find "lightly salted or no salt" chips and many other products. I'm totally amazed that the FDA or other agencies haven't forced lowering of salt in food products. It is a known fact, sort of like tobacco causing cancer, that salt is a major contributor to obesity and heart related issues.
Our food industry needs to get involved NOW. Ever have to wait at Burger King for no salt fries? The "king" instructs the french fry area to salt fries, BIG TIME ! Watch them poor it on sometime. I've complained endlessly, but management fails to listen, they'd rather see me wait for 10 minutes for my unsalted fries. Little do people realize that the salt in ketchup is more than enough to meet the salt taste of french fries.
Also many current "Lays" chips are so heavily salted, I can't eat them. Yes, another intervention, but its long overdue in the entire food industry. Tobacco survived, there it was people quitting, this can be easily solved by simply "lightly" salting things and their products will still sell !

You say you cut your salt intake and that, to me, is the key of it all. Do we need food producers to cut down on salt for us? No. We are perfectly capable of doing this on our own if we have the willpower and discipline. I think this is what Michael might be trying to say.
The government or whatever institution can try making foods healthier, making it easier to identify healthy or unhealthy foods, and all that, but in the end, its up to us to not eat what we know isn't healthy. I'm in good shape (incl. blood pressure, fat percentage, cholesterol, etc) according to my physician and I. Is this because of diet soda? No. Is it because I'm eating products that shout "No trans fat!"? No. Is it because of products containing less salt? No. It's because I am capable of not eating french fries and hamburgers too often. I'm capable of not dousing my potatoes in salt. I'm capable of eating less chips than are in an entire bag.
Many people nowadays just don't have the willpower or discipline to do what is good for them. Everybody knows that instead of sitting here looking at a computer screen, they could be outside taking a walk, swimming, or working out on the eliptical machine in their bedroom. Everybody knows too much salt is no good, as is too much of anything. It's common sense. And as long as people refuse to listen to their common sense and blame their problems on media, advertising, or whatever, they are going to have high blood pressure, be overweight, or have other similar problems.
As to you, Susan, way to go! Staying away from things can be tough, but you did it and succeeded. That takes strength and you've got it. Props!
4-29-2010 @3:36PM Mary said... I love my salt and will contunue to use it until a docter not the governmet tells me to cut back. And at 65+ I don't figure on doing that any time soon. Next thing the government will tell us what we are allowed and not allowed to eat.
4-30-2010 @9:38AM k said... Yeah, the Wall Street Journal. That's where I'd go to find the latest scientific research. Good choice - if you believe a journalist knows the difference between NaCl and KCl.
4-29-2010 @5:11PM Victor said... I didn't realize until recently, and I don't think many ppl do, there is a difference between "salt" and "sodium" the first thing processed food manufacturers can do and you can do for your salt shaker is switch to Kosher salt, per tbl spoon regular Salt has 590mgs of Sodium while Kosher Salt only has 280 for the same amount, it's the Sodium in Salt that raises your blood pressure, sounds confusing I know but it's a fact, So just switch, and right there your reducing your Sodium intake. Mickey Dees, Burger King etc Kosher Salt as soon as possible!
4-29-2010 @8:22PM Paul said... Susan,
All salts have the same amount of sodium per gram of salt. Kosher and Sea salts SEEM to have less sodium but that is only by VOLUME because the granules are shaped differently. So, yes, measured by volume, kosher salt has less sodium, but by WEIGHT it is the same.

From a biological imperative these three things are required for life, but very uncommon in the natural world. Since we can now create them in their pure form in any quantities we want, a so called "proper" diet requires us to fight what our bodies are telling us to do and not simply consume without end. So yes, watching salt intake is up there with fat and sugar.

I try to eat organic and non-GMO foods whenever I can..I am 46 and have definitely learned that my metabolism isn't what it used to be! So my husband and I have changed a few things to help us maintain our weights.. we actually go to Pilates 2 x a week.. that has been great for us...another tip.. cut the meals you eat out! we have been cooking more to help us make better choices.. the problem... the lazy old bag wasn't doing his fair share of the cooking! So I went out and got him a very appropriate (and completely politically incorrect) cookbook... I can't tell you the name.. but if you google "whipped and beaten culinary works" you will find it.. but seriously.. don't go if you get offended easily and you don't have a good sense of humor!
4-29-2010 @6:20AM Misty said... Whats sad is america has gotten fatter because we are all so dang parinoied about what we eat! Look at most of our parents.

Heres whats bad for you EVERYTHING! were all going to die from something comeon people live your life and be happy and healthy. We were all not born with the gene that makes us super models!

4-29-2010 @8:29AM Teresa said... Exactly! People's bodies weren't designed to last this long! This is whats wrong with the world ... too many of us are living wayyyyy too long now. We cannot feed the people living on this planet now, whats gonna happen as it gets worse ... when we all live to be 125? Where are we gonna live? How are we gonna live when we cut down all the trees to make places to live? WE AREN'T! Live a long, happy, SHORT life and get over all this other unimportant crap! I plan to.
4-29-2010 @9:48AM jlw said... They were also alot more active than most are now, had fewer chemical additives to food, a whole lot less lab altered food, and no fast food available on every corner. Farmers ate bacon, eggs, butter, beef,salt, sugar, but - engaged in some sort of physical activity all day, every day and lived long lives (no, spinning around on your desk chair doesn't count as physical activity).
4-29-2010 @2:08PM thomas carney said... The things I read here are typical of normal, average people who just don't get it. First of all, we are "meant" to eat anything or to live a certain length. Overpopulatiohn is a myth (whole world could fit into texas each with home), and "mother nature" is nothing more than a buzzword. "Messing with nature" is what we do all the time...what do you think steel is? Or cement? Or medicine? All of these things "aren't nature", yet we use them anyway. People are afraid of anything different and scientific, and goes "against nature"-- well there IS no such thing as nature, whatever is, just is. So if thet change the shape of salt, good, thats the shape of salt on the chips. If you really want to keep everything natural, go live in a cave.
@Teresa, the world can support a much longer lifestyle- humans aren't "meant" to live anything, which is why I am a transhumanist and life extensionist- I think technological can radical increase the human lifespan.
