Quoted from a site that is both alarmist and paranoid. They react as if "industry" is somehow associated with evil. Yes, salt is processed. But there is absolutely nothing wrong with processing.
Are some foods we eat overprocessed? Very likely, but certainly not all of them, and none are bad when eaten in reasonable quantities.
Are all processed foods bad just because they are processed? Don't be ridiculous. You are processing foods when you cook them. Whole grain flours are processed. Unbleached flour is no better for you any other refined carbohydrate.
Processing simply makes it more useful for consumption. Without processing some of the foods we eat would be unavailable more than 100 miles from the source. Some foods would be inedible. You can determine for yourself what level of processing is okay for you, but that doesn't mean that your ideas are the only useful ones.
You believe what you like, but don't try to use those alarmist scare tactics on me.
