Whether or not you need more salt depends entirely on your individual circumstances and health status. While excessive salt intake is linked to numerous health problems, a deficiency can also be detrimental.
The Importance of Sodium
The human body requires a small amount of sodium (the main component of salt) for crucial functions such as nerve impulse transmission, muscle contraction, and maintaining proper fluid balance.

Risks of Excess Sodium
High sodium intake is strongly associated with increased blood pressure, a major risk factor for stroke and heart disease [Source: US News & World Report, FDA]. The kidneys work to eliminate excess sodium, but if they are unable to keep up, it leads to health complications. [Source: Harvard Health].
When More Salt Might Be Necessary
There are specific situations where increased sodium intake may be beneficial or necessary:
- Intense physical activity: Athletes engaging in prolonged, strenuous exercise can lose significant amounts of sodium through sweat, necessitating replenishment [Source: Prevention].
- Certain medical conditions: Some individuals with specific health conditions, such as those with low blood pressure or those experiencing excessive fluid loss, may need to increase their sodium intake under medical supervision. [Source: Chief Nutrition]
The Bottom Line: It's Complex
The statement "Do we need more salt?" is too broad. The answer is highly personalized and depends on individual health, diet, and activity level. While most people consume excessive sodium, a deficiency can occur and it's important to consult a healthcare professional or registered dietitian for personalized guidance. Simply adding more salt without medical advice could be harmful. [Source: Chris Kresser]
