Excessive salt intake can cause dehydration and severe headaches. High blood pressure is the biggest cause of high blood pressure.
Excessive thirst is a common reaction to eating salty foods and naturally leads to an increase in fluid intake. This intake also naturally causes increased urination, says British dietitian Olivia Burley. The recommended amount of salt for the body is about six grams per day, equal to one teaspoon, according to British nutritionist Pippa Hill. But beyond this amount, experts agree, salt can be harmful to our health.
