We recently wrote about how avoiding five specific bad habits can significantly extend your life. Now, a new meta-analysis published in The BMJ adds further weight to the argument for eating less salt and being healthier.
According to the meta-analysis of 133 clinically randomised trials, lowering salt intake reduces blood pressure – even in individuals who are not yet at risk of hypertension-related conditions. This is important because heart disease is the number one global killer and high blood pressure is the leading cause of heart disease. Furthermore, hypertension is also the leading cause of stroke, heart failure and kidney disease, highlighting how potentially beneficial a low slat diet could be for many people.
Interestingly, the research found that the greater the reduction in salt intake, the greater the benefit to blood pressure.
At present, U.S. government guidelines advise Americans to not consume more than 2,300 milligrams (mg) of salt per day as part of a healthy eating pattern. However, the vast majority of U.S. adults are eating more sodium than they should -- average of more than 3,400 mg each day.
One of the biggest problems is the amount of salt that is contained in manufactured foods, which is usually added to enhance flavour, texture and colour, as well as improve longevity. So even if you don’t reach for the salt shaker at every mealtime, you could still be consuming too much.
It’s good to get into the habit of checking the foods you buy to see how much they all contain. After all, just a small reduction could significantly improve your health and reduce your risk of early mortality.
Speaking about the findings of the research, lead author Feng He, a researcher at Queen Mary University of London, said: “The totality of evidence in the JACC review and this latest BMJ research shows that reducing our salt intake will be immensely beneficial.”
