We're finally catching up with reality, at least in one arena. In the past week I've read two local newspaper articles, one article in the Annals of Internal Medicine and an accompanying editorial in the same monthly journal from the American College of Physicians, all on our need to decrease our salt intake.

Those of us who've spent much of our medical careers dealing with the treatment and the consequences of high blood pressure, medically termed  hypertension, have been on a low-salt kick for years. Both of my parents and, eventually my older brother had hypertension, so I watched my blood pressure for years and, when it went up to high normal, cut way back on my salt intake. I also started to lose weight and to exercise more.

So two days ago I read an article titled "Shaking the Salt Habit." That was written for our Fort Collins paper and was followed by one today, from the Associated Press, titled "Too Much Salt: Report urges FDA to force rollback. Then there were the two medical pieces which came out in the April 20th edition of the  Annals. The editorial encapsulated the concept: "We Can reduce Dietary Sodium, Save Money, and Save Lives.

The bottom line is the American diet contains roughly twice as much salt as is optimal for health, nearly 4,000 milligrams vs. the maximum recommended of 2,300 mg. for young, healthy adults, and the 1,400 to 1,500 mg. that is the suggested maximum for people with high blood pressure, for African-Americans and for anyone older than 40. Much of the excess comes from processed foods.

Other countries have already made progress along the lines of cutting average salt intake (salt, of course, is sodium chloride, but I'm used to using either term). The UK started in 2003, and cut salt intake by an average of 9.5% The Annals article suggests if we were able to do the same, gradually perhaps so people didn't think the taste of food was inferior and started salting things at the table, we'd save lots of lives.

The consequences of hypertension include heart attacks, strokes and kidney failure. That less than ten percent decrease in our dietary salt could prevent over a half million strokes and just under a half million heart attacks in our 40 to 80-year old group. That would save over $32 billion dollars in medical costs.

The UK plans further cuts in salt intake, up to a 40% decrease by 2012. Japan, Finland, Ireland, Australia and Canada plus other countries are also implementing similar programs.

We don't cook with salt for ourselves, decrease the amounts specified in recipes when we cook for others, don't add salt at the table and tend to avoid processed foods. I wondered if we were getting enough iodine, added to most or all salt you purchase, but the salt that goes into processed foods, according to the articles I read, doesn't have idoine anyways. Plus our senior vitamins have the RDA (recommended daily allowance) for iodine anyway. So I quit worrying that we'd develop thyroid problems.

The bottom line is we Americans need to wean ourselves off our excess salt habit and doing so will both improve health and save a healthy chunk of change.
