Salt makes almost everything taste better — we add it while cooking to enhance the flavor of other ingredients, sprinkle some into baking to balance out sweetness, and enjoy it in our favorite snacks, like chips, pretzels, and microwave popcorn. Besides these obvious sources, many highly processed foods — foods we wouldn't ordinarily consider salty — contain an unexpectedly high amount of sodium, such as canned goods, salad dressings, cold cuts, various cheeses, flavored yogurts, ketchup, and much more.

While lower salt consumption has long been recommended for people with cardiovascular issues like high blood pressure, researchers from the Finnish Institute for Health and Welfare have presented new research showing a strong link between higher sodium intake and the risk of obesity. This research is set to be presented at the European Congress of Obesity in May 2025.
