Salt - a moderate quantity of salt keeps weakness and sickness at bay. Extremely good for people who have low blood pressure, salt is required by the body for the absorption of glucose. It should be used in controlled amounts in sweet drinks like sweet lemon water/soda to improve absorbability, especially for people who are vomiting or have diarrhea. Not only this, it also helps in the maintenance of electrolyte balance of the body. Required for proper nerve stimulation of the body, lack of salt can lead to weakness and sickness.
