How Salt Raises Blood Pressure

Michael Roizen, M.D. By Thursday, 02 October 2025 11:58 AM EDT Current | Bio | Archive

Pizza, cold cuts, and cured meats, burritos, tacos, chips, bacon, frankfurters, and sausages are major sources of excess salt in the American diet.

And the salt in those foods doesn't just impact how the heart and kidney function, leading to high blood pressure (HBP). It also activates immune cells in the brain, triggering inflammation that causes the hormone vasopressin — produced in the hypothalamus — to increase your blood pressure.

A lab study in the journal Neuron revealed this salt-brain connection to HBP and inflammation. The researchers say it helps explain why around 33% of patients with HBP don't respond to standard antihypertension medications, which were developed based on the idea that HBP begins only in the blood vessels and kidneys.

Although the average American ingests 3,400 mg of sodium daily, the guidelines say to aim for 2,300 mg or less. The body actually needs less than 500 mg — around a quarter teaspoon — per day  to function properly. (People might need more if they're competitive athletes or working in high-heat environments.)

Ironically, salt substitutes may elevate a person's blood potassium to unhealthy levels if he or she is taking blood-pressure medications such as ACE inhibitors or potassium-sparing diuretics.

Instead, opt for flavor-enhancing spices, herbs, and fruits to add zest to your meals.
