IF you have high blood pressure, you’re in good company. Hypertension afflicts 67 million Americans, including nearly two-thirds of people over age 60. But it isn’t an inevitable part of the aging process. It’s better to think of it as chronic sodium intoxication. And, as an important new study from Britain shows, there’s a way to prevent the problem — and to save many, many lives.

A lifetime of consuming too much sodium (mostly in the form of sodium chloride, or table salt) raises blood pressure, and high blood pressure kills and disables people by triggering strokes and heart attacks. In the United States, according to best estimates, excess sodium is killing between 40,000 and 90,000 people and running up to $20 billion in medical costs a year…

The reason that nearly everyone eats way too much sodium is that our food is loaded with it, and often where we don’t taste or expect it…A blueberry muffin can have more than double the salt of a serving of potato chips. Even healthy-sounding food can pack heavy sodium loads. Two slices of whole wheat bread can have nearly 400 milligrams of sodium, as can two tablespoons of fat-free salad dressing…

We all like the taste of salt, but there is much that food companies can do without driving away customers. Often they add sodium for leavening or food texture rather than taste, when replacement ingredients are available. And sodium levels in similar popular foods made by different manufacturers often vary two- or threefold (for example, a slice of pizza can pack anywhere from between 370 and 730 milligrams), which suggests that many manufacturers can cut sodium levels in their foods sharply without hurting taste. When salt levels in food drop, people’s preference for salt also shifts down, so no one would notice a gradual reduction in sodium across all foods.

That’s exactly what Britain’s Food Standards Agency has done. It divided processed food into different categories, set salt-reduction targets in each category and then asked companies to meet those targets over time. And as they did that, from 2001 to 2011, sodium consumption by the British fell 15 percent.

The new study shows that this drop in salt intake has been accompanied by a substantial reduction in average blood pressure, a 40 percent drop in deaths from heart attacks and a 42 percent decline in deaths from stroke…

There is absolutely no reason we can’t do an initiative similar to Britain’s on this side of the Atlantic now…A proposal as important to human life as this needs the stature and resources of the federal government to bring…the food industry along. The F.D.A. has been developing a new plan for a voluntary, coordinated, national initiative. Unfortunately, even though it is voluntary, the food industry is fighting it, and the plan is stalled.

Per usual, bought-and-paid-for politicians are as much part of the problem as bureaucrats and behemoth corporate budgets. As a side issue, one more reason to adopt an election model that allows NO private or PAC donations and probably includes a short regulated electioneering season. Take the money out of elections and you take most of the money out of political graft.

That still leaves us with libertarian silliness over the government stepping in on the side of medicine and science. But, fools can still add as much salt as they wish to their beer and onion dip.
