But food manufacturers aren't likely to lower their products' sodium content voluntarily. The simple fact is that salt makes processed food taste good. In Salt, Sugar, Fat author Michael Moss discusses how companies use salt as "the great fixer." Lots of processed food tastes genuinely bad without loads of salt. To prove it, some researchers at Kellogg made versions of their most popular products with no salt. Moss wrote that "The Corn Flakes tasted like metal filings, the Eggo frozen waffles like straw. Cheez-Its lost their golden yellow hue, turning a sickly yellow, and they went all gummy when chewed. The buttery flavor of the Keebler Town House Light Buttery Crackers, which contained no actual butter to start with, simply disappeared." They even showed the drop-off point. Oscar Meyer ham tastes okay with 37 percent of the salt removed, but drop it by another 3 percent and Moss wrote it tastes "like rubber." No company is going to put out a ham that tastes bad, even if it's better for their customers' health. And that means it's up to you to simply not buy those products in the first place.
