Is salt dangerous? Certain organizations – such as those issuing official dietary guidelines – have warned for a long time against salt and recommended a reduced intake. But as often when it comes to nutrition, the science is far from settled.
A recent review of all good studies in this area shows that the amount of salt that most people consume is associated with good health. Both an extremely high salt consumption and a low consumption seem to be worse.

The review can be added to several similar reviews in recent years, that question the dead-certain warnings against salt. Neither too much, nor too little, seems to be best.
You can actually get too little salt. This causes fatigue, dizziness and difficulty concentrating. You lose focus. And maybe you don’t just feel worse from salt deficiency, perhaps it’s also really bad for your health.
Avoid high doses of salt from junk food, cheap processed foods, soda and bread. Extreme amounts of salt are hardly good for you, and there are more reasons to avoid such foods. But if you eat real food, you can probably put as much salt on your food as you like.
If you have symptoms of salt deficiency, try taking half a teaspoon of salt, dissolved in water. If you quickly feel better, you were probably salt deficient.
