From the crusader credited with popularizing the phrase "junk food," Salt Wars uncovers the group of scientists who worked with food industry lobbyists and fought all efforts to reduce the dangerous levels of sodium in our food.
A high-sodium diet is deadly; studies have linked it to high blood pressure, stroke, and heart attacks. It's been estimated that excess sodium in the American diet causes as many as 100,000 deaths per year. And yet salt is everywhere in our diets--in packaged food, fast food, and restaurant meals. Why hasn't salt received the sort of attention and regulatory action that sugar and fat have? In Salt Wars , Michael Jacobson explains how the American food industry have fought government efforts to reduce dangerous levels of sodium in our food.
I read this along with The Salt Fix by DiNicolantonio so that I could get both sides of the story at once. However, the few studies referenced in this book have numerous problems. Even the author admits that much of the evidence is inconclusive. For example, lower blood pressure MIGHT be due to lower sodium levels, but it might just as easily be due to significant weight loss by a study's participants. Instead of trying to design better studies, which the author says would be too expensive, he simply says that if the American Heart Association and others insist that salt is harmful, then it must be harmful, and everyone should drastically reduce the sodium in their (our) diets. The Salt Fix by DiNocolantonio is much more thorough, offers many more studies (both for and against salt, although admittedly most are pro-salt), and outlines some of the dangers of lowering sodium intake for certain populations (such as pregnant women). Lower sodium levels are sometimes (often?) accompanied by an increased heart rate, which negates any benefit of the slightly lower blood pressure obtained. All in all, I was disappointed in this book. It did not convice me that salt is the enemy of good health.
I really liked this book, as a whole. It’s very well researched, and the fact that the author has been one of the major proponents of limiting salt in the American diet says much about his credentials. One aspect of this battle is how absolutely firmly entrenched and adamant the food industry is against any type of compromise or willingness to, as a group, reduce the amount of sodium in their products. Included is the vast majority of restaurant owners in refusing to do so, as well. A very few food product manufacturers have, on their own, worked to somewhat limit the amount of health-damaging sodium in their food products and I applaud them. The only negative in the book, to me, was the insistence by the author to accuse all Republicans, as well as Republican legislators as a whole, of refusing to allow any helpful legislation to be passed. It’s as if he feels that every non-Democrat is too stupid to realize that a salt-laden diet is harmful. Other than that it’s an excellent book and I highly recommend reading it to learn of the fight to limit and restrict sodium in our food supply. I especially appreciate those who don’t want our children to grow up physically damaged by the foods they eat, at home, at school and in restaurants.
Michael F. Jacobson, foremost nutrition advocate and founder of Center for Science in the Public Interest, pens a memoir to his multi-decade campaign to improve America's health.
In what one hopes will be the first of many volumes: this book details the enduring Food Politics when scientists, government organizations and food lobbyists battle out efforts to reduce America's consumption of salt in processed and prepared foods.
This book is primarily written to answer those in the salt industry and medical community who refuse to see sodium as detrimental to our health. It's a bit too academic in nature, so not necessarily something for everyone, but it's a good book.
