Why do we crave salty foods?

Salt isn’t just a seasoning, it’s a chemical compound (sodium chloride) that our bodies need to function.

Sodium helps regulate fluid balance, muscle contractions and nerve signals. But here’s the catch: we only need a small amount and our modern diets often exceed this by a mile.

Habitual eating: Most processed foods like chips, biltong, instant noodles and takeaways are loaded with salt. Over time, our taste buds get used to these high levels, making us crave them even more.
Stress and boredom: Ever noticed how you reach for salty snacks when you’re feeling overwhelmed or bored? The crunch and savoury taste provide a sense of comfort.
Dehydration or mineral imbalances: Sometimes, salt cravings might indicate dehydration or a lack of essential minerals, especially after intense exercise.
Underlying health issues: Persistent salt cravings could signal thyroid or adrenal gland problems. If your cravings seem excessive or unusual, it’s worth consulting a doctor.

It’s easy to blame the salt shaker but the truth is, that most of the salt we consume is hidden in processed and packaged foods. Think about it.

Even seemingly healthy options, like salad dressings, breads and breakfast cereals, can pack a surprising amount of sodium.

How excessive salt affects your health

Eating too much salt doesn’t just raise your blood pressure. It can lead to:

Heart disease and stroke: high salt intake puts extra strain on your heart and blood vessels, increasing your risk of life-threatening conditions.
Kidney damage: your kidneys work overtime to filter excess sodium from your bloodstream, which can lead to kidney disease over time.
Osteoporosis: a high-salt diet can cause calcium loss from bones, making them weaker.
Bloating and water retention: Too much sodium makes your body hold onto water, leaving you feeling puffy and uncomfortable.
