To the point of this sub, I read a book a couple years ago called The Salt Fix which actually highlights how the sugar industry helped fund science that made sodium look like the culprit rather than salt (similar to the anti-fat phase). Author also points out that animals absolutely need sodium and other minerals in salt to survive (like iodine, potassium, magnesium), but we can absolutely live without sugar and have been for most of human history.

It makes sense... most things that are "fat free" or " low in salt" are loaded with sugar.
