The Federal Government's Killer Salt Advice

The Federal Government’s Killer Salt Advice

A new study published in the Journal of the American Medical Association (May 4), reports that among 3,681 study subjects followed for as long as 23 years, those on a low-salt diet were more than 50% more likely to die from cardiovascular causes than study subjects who consumed substantially more salt.

The researchers concluded that their findings “refute the estimates of computer models of lives saved and health care costs reduced with lower salt intake” and they do not support “the current recommendations of a generalized and indiscriminate reduction in salt intake at the population level.”

But that sort of reduction is precisely what the U.S. government now recommends.

In April 2010 the Institute of Medicine (IOM) issued a report calling for Americans to reduce salt intake from an average of 3,400 milligrams per day to 1,500 milligrams per day, and less for those over age 50.

The IOM report claimed that such population-wide reduction could prevent more than 100,000 deaths annually. “Sodium intake is too high to be safe,” was what Dr. Jane Henney, former commissioner of the U.S. Food and Drug Administration and chairman of the IOM committee that produced the report, told the media at the time.

Then this past February the U.S. Department of Agriculture incorporated the IOM’s recommendations into the federal dietary guidelines.

So who should we believe?

The new JAMA study didn’t break any ground with its finding. In fact, a host of studies published since 1995 fail to show any improved health outcomes for broad populations on reduced-salt diets.

While the new study authors rightly acknowledge that their current findings “do not negate the blood pressure-lowering effects of a dietary salt reduction in hypertensive patients,” only a small portion of the population has that pathological condition.

Given that there is no scientific evidence showing dietary salt by itself to cause hypertension, as opposed to simply contributing to the condition once it already exists in individuals, a population-wide recommendation to reduce salt intake is simply unwarranted.

Imagine if the government made a population-wide recommendation limiting sugar intake because some people have diabetes. Personal health matters are more appropriately handled on an individual physician-patient basis.

But of course the matter is more serious than simply the Nanny State taking away food’s tastiness by making it less salty. Proverbially rubbing salt in the wound, the federal government’s advice could actually kill people, according to the new study, as well as prior research.

There is a larger point here that goes beyond salt.

Since the 1970s the federal government and the alarmist public health establishment have been telling Americans what to eat. Don’t eat butter; switch to margarine. Reduce egg intake. Eat less meat. Eat more fiber and grains.

But there isn’t any sound science behind any of this advice. As it turns out the public health establishment now ranks trans fat-containing margarine as less heart healthy than the butter it replaced. Oops. Eggs too have been exorcised, except perhaps for those individuals with a pathological cholesterol condition. And the dietary fiber myth was never based on any science to begin with, junk or otherwise.

The reality is that while many tasty foods are easily demonized and made politically incorrect, and while many not-so-tasty foods are haloed and made politically correct, precisely what foods and how much of them individuals can healthfully consume is far more complex than the government is willing to admit.

The vast majority of us can enjoy, say, regular sodas, salted pretzels, hot dogs, buttered popcorn or whatever as part of a healthy lifestyle. There are no good foods or bad foods, despite food nanny badgering.

And then imagine passing up the pleasure of salty chips only to have that sacrifice actually cause or contribute to your heart attack.

Yes, Virginia, there are also scientific reasons for the government to stay out of our personal lives.

  1. My intuitive ring of truth has always been to ignore all that junk–butter tastes better, margarine tastes OFFal. above the salt is nonsense—and bless you for intervening. I must always check with you.

  2. my wife had a spke in blood pressure when hospitalised for severe headaches. they put her on a low salt diet. bloodpressure would not come down even with medication. more restrictions on salt and medication…bloodpressure even higher. she said screw it from side effects and trouble staying on diet, went back to regular food. within 1 week bloodpressure down to normal. her pcp[who was taken out of the loop by ‘specialists’ believe the pressure spike was pain related and all the diet restriction and meds caused her pressure to rise. one size does not fit all and heaven help these caught in the governments trap.

  3. The low salt diet probably resulted in low iodine and poor thyroid function since the MAJOR source of iodine in the US is iodized salt. This could easily explain the increased mortality. Another reason to avoid sea salt as it has no iodine.

  4. Too much of anything is bad for you. By the same token the human body is a wonderful machine that will keep on going despite many, MANY, abuses to it. To be honest I am more worried about pathogens then I am about salt intake, think about it salt that mineral in and of itself, has been created as on of the tastes our mouth can taste!!! Why, because it is HIGHLY important for our bodies to consume it.

    Thanks Steve for talking about this study. May we find more people who ignore Governments advice in the future.

  5. The underlying problem here, and in many similar instances, is the unwarranted assumption that people in Government are smarter than people who are not in Government.There is no reason why this should be so,and events have proven again and again that it isnt so.Also there is no reason why”Government” should be involved at all in what we eat.That is not Governments business.
