40% is some kind of magic number in the food world. A ton of your standard off-the-shelf spirits check in at 80 proof, i.e. 40% alchohol content. Kinda likewise, a lot of canned foods seem to provide you with roughly 40% of the USRDA of sodium.
Hormel Chili No Beans, the food substance I hate to love, is one example. Campbell’s Chunky Soups are another. Except for one important note: that’s 40% of your daily sodium intake PER SERVING, and the cans I was looking at allegedly contain “about two” servings. So if like a normal human you eat the whole can of soup, those Saltines you were eyeing as a side dish are not a great idea.
I think eating “low sodium” or “low fat” variations of your favorite foods is a dead end. They don’t taste as good. Makes eating a chore. A more useful idea is to get your flavor from healthier seasonings. Black pepper – good on fries. Chili peppers, bell peppers, onions, garlic – good eatin’. Skip the ketchup-flavored corn syrup and go with salsa or mustard.
