When it comes to salt consumption, many of us immediately think of blood pressure, but a diet containing high salt does not only affect people’s blood pressure. It also weakens the immune system. A study published last year in the journal Science Translational Medicine states that people who eat a high-salt diet suffer from more severe bacterial infections. The same study also showed severe immune deficiency in people who consumed an extra 6 grams of salt per day. The World Health Organization recommends consuming less than 5 grams of salt per day in order to prevent obesity, diabetes and some diseases, especially hypertension and heart diseases.
