Too much salt weakens the immune system
When understanding the relationship between low sodium and immune system, is low sodium good for the immune system? According to a recent study at the University of Bonn, it could be.
The researchers mentioned two studies: an experiment with animals and research with human participants.
The animal study showed that mice with increased levels of sodium exhibited 100 to 1,000 times more disease-causing pathogens. Urinary tract infections in laboratory mice also seemed to heal more slowly when they have high levels of salt in their body.
Likewise, volunteers who consumed 6 grams of salt on top of their usual diet for a week seemed to develop a weakened immunity. The researchers noted that their immune cells “coped much worse” with bacteria after their high salt diet.
How much is too much salt
Now that we have a better understanding of how low sodium could be better for the immune system, let’s talk about healthy salt intake. So does low sodium and immune system have a connection?
According to experts, adults should have no more than 5 grams of salt (2 grams of sodium) per day.
The problem is, most people consume about 9 to 12 grams of salt daily. That’s more than twice the recommended amount.
It would be helpful to remember that many foods already contain salt, so reaching out for the salt shaker to add taste to meals might lead to excessive salt intake.
