For decades, salt has been labeled a dietary villain. Public health guidelines have repeatedly warned us to cut back, linking sodium intake with high blood pressure and cardiovascular disease. But what if this advice doesn’t apply to most people?
Emerging research suggests that only about 15% of the population is truly “salt sensitive”—meaning that their bodies react to increased salt with swelling or a rise in blood pressure. That leaves the remaining 85% who may actually benefit from increasing their salt intake—especially those eating a whole-food or low-carb diet that naturally reduces sodium.
Salt Isn’t the Enemy for Most People
Salt (sodium chloride) is an essential nutrient that supports vital functions in the body, including:
- Hydrochloric acid production for proper digestion
- Electrical signaling via the sodium-potassium pump
- Fluid and electrolyte balance
- Muscle function and nerve transmissionAs more people shift toward real food and away from processed, packaged products, they’re also unknowingly slashing their salt intake. This can lead to a host of symptoms like:
- Headaches and migraines
- Brain fog
- Leg cramps and muscle pain
- Restless leg syndrome
- Low blood pressure and dizziness
- Stomach acid deficiency (bloating, reflux)
These symptoms may not signal disease—but rather a nutrient deficiency: salt.
The Case for More Salt – Within Reason
Most major health organizations currently recommend limiting sodium to 2 grams or less per day, but traditional diets in ancient cultures often included far more—without the rise in chronic disease we see today.
Standard salt intake used to range from 5–8 grams daily, depending on region and health policy. In contrast, a strict low-salt diet can become dangerous for those drinking large amounts of water or eating very clean, unprocessed meals. In fact, overhydration without electrolytes can flush sodium and other minerals from the body, potentially lowering sodium blood levels and worsening symptoms.
A good rule of thumb: If you’re drinking more than about 100 ounces of water daily, you may need to increase your salt and mineral intake.
Practical Tips for Increasing Salt Safely
Increasing your salt doesn’t mean pouring tablespoons into everything you eat. Try this instead:
- Measure out 2 teaspoons of sea salt or mineral salt into a small bowl each morning.
- Throughout the day, pinch small amounts onto your meals or into your water.
- Do not dump all the salt into one water bottle—this can cause digestive upset or act as a laxative.
Start slow and pay attention to how your body responds. Many people notice improvements in energy, clearer thinking, fewer cramps, and even reduced headaches or migraines.
🧠 Extra tip: Consider exploring the Stanton Migraine Protocol, which discusses the role of salt in headache prevention.
But What About Blood Pressure?
For those in the salt-sensitive 15%, caution is still warranted. But even for individuals with elevated blood pressure, sodium alone may not be the culprit—sugar, insulin resistance, stress, and other lifestyle factors often play a bigger role.
Routine bloodwork that shows sodium at the low end of the reference range may not be ideal. Many patients feel better with levels in the upper half of the normal range, especially if they’ve been experiencing symptoms like fatigue, headaches, or dizziness.
Final Thoughts
Helping patients unlearn outdated fears around salt can take time and repetition. But by shifting the focus from restriction to nutritional adequacy, we empower people to meet the actual needs of their bodies.
