One of the big complaints processed food companies, physicians in clinical practice, and the great gourmet media all have in common is that cutting back on salt would make food taste flat, and you as an individual wouldn’t necessarily get a big drop in your personal blood pressure from doing it. They argue that only “salt-sensitive” people have to worry about their intake, and anyway, a few points lower, they all say, isn’t really impressive enough to give up your 300-mg serving of sodium in a bowl of Kellogg’s raisin bran or 390 in a slice of La Brea sourdough. And don’t, for g-d’s sake, ask your favorite name brand celebrity chefs to stop salting early and often in each dish!
A big statistical modeling study in the New England Journal of Medicine this week knocks all this wishful thinking on the head, and does it very nicely. The study looked not at individual blood pressure drops but the health and cost benefit of dropping average salt intake by 3 grams a day over the entire U.S. population.
The researchers found that if everyone drops their salt intake back down, the benefits start to look like the ones from quitting smoking, cutting cholesterol and saturated fat, and losing weight to get to a normal BMI.
That’s because even when individual blood pressures drop by only a few points, they’re not going up (as they are today), and when a small average drop happens in a very large group, the big bell curve of disease shifts toward lower risk of consequences and later starts for developing heart disease and high blood pressure. After the first national cholesterol lowering guidelines were issued in the late 1960s, the nation’s heart disease and stroke risk dropped by about a third, and at least until obesity and blood pressure started to cause a back-reaction, the average age for a first heart attack went from 50 to 60 in men. That’s a huge kind of benefit.
The combined drop in heart disease and stroke deaths from cutting salt would be something like 200-400,000 people per year, a lot more than can be saved by simply putting everyone on blood pressure medications–the study made that comparison directly.
Altogether, a solid recommendation for dropping sodium levels in processed and restaurant foods, which make up about 80% of today’s sodium intake. And for not imitating processed food and chain restaurant thinking in your professional or home cooking, as Francis Lam seems to in his Salon.com commentary on the new NYC Department of Health initiative. And if there was any doubt that the Culinary Institute of America has been training Continue reading
