Why Is Too Much Salt Harmful?

Consuming too much salt can negatively impact health, primarily by causing high blood pressure (hypertension). High sodium levels in the body cause water retention, increasing blood volume and putting extra strain on the heart and blood vessels. Over time, this raises the risk of heart disease, stroke, and kidney damage. Excess salt intake can also lead to fluid retention and bloating, making the body feel swollen or puffy. Additionally, a high-salt diet may contribute to osteoporosis, as excessive sodium can cause calcium loss from bones. Processed and fast foods are often loaded with salt, so reducing intake by choosing fresh, whole foods and using herbs or spices instead of salt can help maintain good health. The World Health Organization (WHO) recommends consuming no more than 5 grams (about one teaspoon) of salt per day to prevent health complications.
