Too much salt causes you to retain water. I'm sure you've heard that expression before. When the blood is moving through your veins, carrying nutrients to the cells, those nutrients must pass through the cell wall by osmosis. Salt stops that process. Nutrients can't get in and wastes can't get out.
Water is retained, waste is retained.
I have nothing good to say about fried foods. That's how much fat is in it. And what do you need it for anyway. By getting rid of fried foods, you eliminated an enormous amount of fat, fibreless food and a lot of salt. Fried food elimination was high on my list of things to stop eating back in 1990.
