1, cause the weakness of the limbs, because the normal skeletal muscle contraction and nerve conduction requires the participation of salt, if long-term salt is not eaten is likely to cause a decline in limb strength. 2, may lead to edema, because salt has an important role in regulating the balance of fluid distribution in the body, if long-term salt is not eaten will cause changes in the osmotic pressure inside and outside the cells in the body, which will cause a high incidence of edema. 3, may It may cause a decrease in digestive capacity, resulting in a high incidence of acid reflux and heartburn, because sodium chloride is needed as a raw material for the synthesis of gastric acid, and a lack of salt may cause a decrease in gastric acid, resulting in a high incidence of acid reflux and heartburn due to a decrease in digestive capacity.
