Why salt should be used with moderation?

Answer 1

Salt is needed in the diet, but a well-balanced diet already contains enough salt. Salt = table salt = sodium chloride (This answer also refers to sea salt.) Short term use of salt causes water retention, which increases blood pressure, which can cause a headache. Long term use of too much salt can cause more health problems such as high blood pressure and cardiovascular disease. That too, can cause more headaches. An old traditional method of suicide involved consuming a pound or so of salt. That'd possibly cause headaches & problems for more people besides just yourself! Potassium chloride tastes like table salt, and is among the modern commonly used salt substitutes for table salt (sodium chloride) for those on a low sodium diet, but salt substitutes have their own sets of negative medical side effects.
