Cutting teen salt could save future health costs

Reducing the amount of salt teens eat by 3 grams per day – that's about 1,200 milligrams (of sodium) or a 1/2 teaspoon of salt – could lead to a 68 percent decrease in the number of teenagers with hypertension and also lower the number of U.S. adults with heart conditions in the future, says new research from epidemiologists at University of California, San Francisco. [Update: Some commenters expressed confusion about the 1,200 milligrams. This number is the amount of sodium in 3 grams of salt. The American Heart Association also answers questions about sodium on their website.]

Hypertension or high blood pressure can lead to strokes and heart attacks, and although these problems are not common in teens, studies have found that young adults in their 20s and 30s who have high blood pressure often began the struggle as children.

Dr. Kristin Bibbins-Domingo, lead author of the UCSF study, says the taste for salt is a learned behavior, and so early intervention is key. "We can hopefully change the expectation of how food should taste,  ideally to something slightly less salty," she says.

Bibbins-Domingo used a computer model to analyze cardiovascular disease in teenagers between ages 12 and 18 and predict how lowering salt intake for this age group could help decrease the numbers of hypertensive adults in the future.

The study found that if teenagers today started eating a 1/2 teaspoon less of salt each day, there could be as much as a 43 percent decrease in the more than 2.7 million adults between ages 35 and 50 who suffer from hypertension.

"If you start with higher systolic and diastolic blood pressure numbers in your teens, you'll likely have even higher numbers in your 20s and 30s." Bibbins-Domingo explains.  "Your body gets accustomed to foods you eat, so the key is to set habits for healthy eating throughout your life."

The results of this study are being presented at this year's American Heart Association Scientific Session.

The USDA currently recommends people over age 2 eat fewer than 2,300 mg of sodium per day – the equivalent to about 1 teaspoon of salt. However, researchers say most Americans eat nearly twice that much, with teenagers consuming more salty food than any other age group.

Experts say paying attention to nutrition labels and making gradual reductions in the amount of sodium your teenager eats can help.  For a list of common foods and the estimated number of milligrams of sodium each contains, visit the USDA's National Nutrient Database. Also, the National Institutes of Health provides this blood pressure table, to help you understand the healthy blood pressure ranges for children between ages one and 17.

      I was wondering how they would get such a bizarre number like 1200, and then after some searching I realized what they did. It turns out that 3 grams of SALT has about 1200 milligrams of SODIUM.

      The article is kind of right. 3000 mg of NaCl (table salt) contains about 1180 mg of Na which is pretty close to 1200 mg. It is the Na that causes the problem.

      Sodium Chloride is salt. 1200 mg is the Sodium and 1800 mg is the Chloride which totals 3 grams or 3000 mg. Salt has an ionic bond so it readily separates in water. Comes from Chemistry 101.

    Any chain food store has tons of salt added to the food. When you look up all the food you eat and log your salt/fat/cal/ect.. it is mind boggling! Even when you are eating the healthiest foods, you get tons of salt. I was just logging food in my journal this weekend. I went to Jason's Deli and ate a Grilled Veggie Sandwich (960mg salt), no cheese. I also ate at Chipolte and had a vegetarian burrito (1100mg salt). If I eat at home I barely consume enough salt to even make my daily quota. These chain food locations really need to cut out the salt to truly make the food healthy. I don't even know how they add so much salt. It must be infused into the food!

      As someone with hypertension, I try and avoid salt, and do wish they could cut back on it, but the down side to that is the same as the down side of getting rid of the bad fats in the oils which has left us with tasteless french fries and tasteless KFC Chicken. So remember, we sometimes do get what we asked for with not so fun side effects

    This is another false report about salt. It has been going on for 45 years now and it was a lie when it came out and it is still a lie. Research money is what started it and it is probably why it is still being sold as the truth. It is BS to the millionth degree.

    If the teenagers are obese or have other medical conditions then salt can make them worse, just as in Adults. For healthy normal weight people salt is self regulating and it is not dangerous. Sea salt has many different minerals in it so it is a more complete and balanced source of salt and probably healthier.

      The problem is no one knows who will be badly affected by too much salt. The best solution is avoid it as much as possible. Salt is used because it is an incredibility cheap way to make almost any food taste better. Humans have a biologically bias to eat salt because until a few hundred years ago it was hard to get. Now it drenches almost all of our food. It is very hard to avoid too much salt except by preparing food from scratch.

    It's not the salt (NaCL) that's bad for you it's the Sodium (Na). Switch to a non-Sodium salt substitute (e.g. KCl). It will add the same salty flavor, while being healthier for most. By adding more potassium (K) while reducing sodium in the diet, you're more likely to achieve the optimum 1:1 Na:Cl ratio, since most individuals tend towards a 2:1 or higher Na:Cl ratio.

    High blood pressure comes from grains (try eliminating all grain ~especially corn...corn syrup, corn sweeteners, corn oil, any other words that imply corn derivatives for three days and see if your condition improves) for me. I need salt to get rid of the extra fluid that I retain when I eat grain...i suspect that's what raises my blood pressure...the extra fluid. I listened to the American Heart Association and lowered salt and did all of the things they said to do. I'm convinced they are a front company to make people have heart attacks earlier from the information they give to people. I met a researcher that worked on salt many years ago at a major big ten university in the midwest...and i gotta tell ya...that guy had issues. I wouldn't trust much from that guy. His project was salt and it's affect on blood pressure. Knowing what I know now, I'd be questioning that information again. I believe they looked at salt by itself and not in conjunction with all of the sugar we eat in the American diet. If grain makes you retain fluid, salt helps you get rid of the excess (either too much or not enough...so there's still a balance there). But to say that salt is bad...isn't quite right. I tend to need salt.

      oh...i forgot. some people think that table salt is the bad one. but not the one with minerals and such. they both work in a pinch for me. the himalayan salt label says that it makes you more alkaline. that's interesting. given that we eat as much sugar (makes you acidic) as we do. it would be interesting to know if that has any effect on our ability to fight diseases to run through the pH system like that. it might wipe out more diseases to cover a spectrum. thinking...

    there's no food in the picture you are showing. it's all corn. it would make anyone blow up. grain makes people sick. you need salt to drop the fluid from the inflamation that you get from corn. (it's still a too much or too little type of thing, but you can control it fairly easily)

      Inflammation makes you retain fluids. (raises blood pressure) but there might be something inherently in grain that eating it makes you retain fluid also (not salt, but sugar? seems to take salt to get rid of it). that's where i'd be looking. but i don't think they really want to know. they wouldn't be able to sell all of those drugs and get all of the patient visits that they get now if they solved this one. ever notice how they study around anything that would actually make sense in these studies?

      just eating grain may have some fluid retention properties to it also. so...you would have to figure those out separately. how much is from grain because it's grain? and how much is from inflammation? i would chase those down. if i had a lab. and people that want to know. but, in the meantime...just don't eat grain and stay away from corn (that's hard) and see if it gets better. and keep a little salt around if you feel puffy. then sprinkle a little bit on your hand and lick it and see if you lose fluid in a couple of minutes. it works. blood pressure of a kid.

    The consumption of salt isn’t the main cause of high blood pressure. There has been a lot of research on this subject. The most reliable result is that if we cut our salt intake by half, the blood pressure declines somewhere between 2 mm Hg and 5 mm Hg. But when we talk about high blood pressure, we mean an overpressure of 25 or 40 mm Hg or even more. Conclusion? Salt intake can’t be the main cause. The real cause is the abundance of carbohydrates.

    This is ABOSLUTELY false and it doesn't surprise me that it made its way to the headlines. The predisposition for hypertension is entirely genetic. In such persons, salt can exacerbate the condition but salt absolutely does not cause or lead to hypertension in persons not susceptible. That study is being driven by insurance carriers who are pushing hard for a healthier America because they have to pay out less premiums, equating with higher margins on profit. They can't state the real truth, but rather try and make you believe that everyone who eats salt as a teen will develop hypertension, leading to strokes, heart attacks, diabetes, blah blah blah. It's corporate massage hard at work on the American people. Trash it.

    When I was younger, maybe 20 or so, I went to the doctor to get a check up and had high blood pressure. I told her I have had high blood pressure pretty much my whole life. She immediately started listing off medications (plural) I would need and scheduled a couple tests to take. Luckily for me, I had just been brought over to sanity regarding the health system in this country, and wanted to avoid medications if at all possible. I asked her if there were any "natural" things I could do to lower my blood pressure. She literally, literally put the pencil down mid prescription and said, "Oh, well high blood pressure is 99 percent a mineral imbalance, so cut out sodium and try a daily supplement for other things." My blood pressure was normal at my next checkup for the first time in my life.

    I wonder how many thousands of dollars per month I could have cost our country if I didn't ask that one simple question. Several tests and lifelong medication rather than limiting salt. Incredible.

    Kieth is correct. Salt weighs 6 grams per teaspoon. In that six grams there are 2,350 mg of sodium. Cutting salt out is easy at home. Bread can be made without it, all meals can be prepared without it, etc. Eating out is where the danger is. Fast food and some chains like Applebee's, etc simply cannot cut salt out. In the west a burger chain known as In-N-Out will cut salt out of the burger and fries. There are support Web sites on the Net like Megaheart.com and others that provide all the data most people need.

    I'll be blunt – This is BS.

    Let's be very clear: There is no scientific fact or even a consensus that lowering your salt intake is good for your health. It is an (overly) cautious assumption that salt is bad for us. Like a lot of things (the bankruptcy of Dow Corning due to the silicone scare is the first that comes to mind), this is based on guesses, loose connections and fears.

    As with all things, look for what real experts and facts have to say. A decade or so ago ('98), the JAMA (as in one of the most prestigious publications around) did an analysis of over a hundred studies on salt and their conclusion was that there wasn't enough evidence to support a general, lower salt intake. This was followed by others that more or less in future articles/studies; this has not changed in recent years.

    Look at the wordings in this article and from the researchers themselves. The key word here is, "could." As in, "I could go outside in the middle of nowhere and be run over by a car." The other key is "computer model." Well, if biology in theory/model was so great, we wouldn't need years of clinical trials. But, we need the trials, because nature is diverse and unpredictable. Using a computer model, and without looking at it I already know that there's no way that they input all the sodium related functions in the human body, filled with assumptions is ridiculous.

    If you have a certain condition, there are things you have to avoid. An ironic one is how those on blood thinners have to avoid eating a lot of broccoli and kale (widely and justly considered to be super foods), because they're extremely high in vitamin K, the vitamin that plays a big role in blood clotting. Likewise, if you already have high blood pressure, reducing your salt intake MAY help you; even that's a maybe, since studies say it will only help about a third.

    For most of us, salt is fine. And, lowering your intake is likely to do more harm than good, since it's something that you need in rather high quantities to, you know, live. How can I be so sure of all this? Because our bodies are pretty damn good at controlling high quantities of stuff. Too much salt in your diet? Well, thank your kidneys for balancing it all out. (Kidney problems are another matter.)

    To sum it up:
    - Computer models do not make for a good biological "study."
    - That lowering salt intake is good is NOT proven/accepted science.
    - Your kidney is good. Be kind to it.
    - It's different if you have a preexisting condition.

    I think that these meals that are being served to kids and teenagers at the fast food restaurants should be reevaluated. If you need any information about health and fitness check out my blog. http://razzlea.blogspot.com/

    Where is the solid evidence that salt ALONE is responsible for these health effects? It's not there. Lowering salt intake is ALWAYS confounded with amount of food (total calories) and type of food.
