Vigorous exercise in warm weather helps sweat out waste products but that's, IMHO, no reason to assume high salt intake is OK. Sweating only gets rid of a portion, rest of salt etc stays in the body & helps keep system puffed up with excess water weight. I don't buy the concept that sodium lost thru sweating needs to be replaced. Sometimes on rides I'll drink CytoMax which has some electrolytes but I rely on it more for the carb/sugar boost to avoid "bonk".
I like occasional pickles/bacon/potato chips but would be best to do without. Low-salt home-made food is best.
