As a health and nutrition expert with a background in public health, I can provide you with an informed perspective on why excessive salt intake can be harmful to your health.

Salt, which is primarily composed of sodium chloride, is an essential nutrient that plays a crucial role in maintaining fluid balance, nerve function, and muscle contraction. However, when it comes to health, it's all about balance, and too much salt can lead to a variety of health problems.

Excessive salt intake can lead to high blood pressure (hypertension), which is a major risk factor for heart disease and stroke. High blood pressure puts a strain on the heart and blood vessels, potentially leading to cardiovascular disease. It can also contribute to kidney problems by increasing the strain on these organs and making them work harder to filter out the excess sodium.

Additionally, too much sodium can cause water retention, which can lead to edema or swelling in the legs and feet. This can be particularly problematic for individuals with heart failure or chronic kidney disease.

In some cases, a high-salt diet can also exacerbate osteoporosis by increasing the amount of calcium excreted in the urine, which can lead to a decrease in bone density.

It's important to note that not all sources of salt are created equal. Processed and packaged foods often contain high levels of hidden sodium, which can contribute to a person's overall salt intake without them realizing it.

In conclusion, while salt is necessary for life, moderation is key. The recommended daily intake of sodium for most adults is less than 2,300 milligrams (mg), with an ideal limit of no more than 1,500 mg for optimal health.
