But the less salt, the better , because in addition to providing a salty taste, the main component of salt is sodium chloride, sodium is an essential nutrient. Once deficient, it may cause potential the threat of hyponatremia, causing fatigue, nausea, vomiting, muscle spasms, and homeostasis disorders.
Therefore, we must learn to reduce salt scientifically in our daily life.
