There’s a reason why junk food manufacturers fill their products with salt: It tastes good! As anyone with taste buds knows, a little salt makes bland food taste better. There is something in salt that we are hard-wired to like. Biologists believe this is leftover from our days as hunter-gatherers, when salt was hard to come by. So it’s normal to crave salty foods sometimes.

One of salt’s main benefits is to promote fluid retention in our bodies. For this reason, dehydration from sweating, diarrhea, or vomiting may increase our taste for salt.

When people develop a salt craving that is new, increased, or persistent, it can be a sign of underactive adrenal glands (adrenal insufficiency). The adrenal glands secrete hormones that help regulate the balance of salt and water in the body.

Other symptoms of adrenal insufficiency include weakness, low blood pressure, fatigue, and weight loss. For a salt craving that’s new, increased, or persistent, see a doctor to make sure it’s not just a snack attack.
