New study: Could low-salt diets be associated with an increased risk of heart disease?


Could it be bad to avoid salt? The controversy over the advice to eat less salt continues with a new study published in the prestigious The Lancet.

Researchers find that people eating a low amount of salt have an increased risk of cardiovascular disease and death. A moderate intake is generally associated with the lowest risk. But people eating a high amount of salt only have an increased risk of heart disease if they also have high blood pressure.

What it means

This study – like most – is based on statistical data, that can’t prove cause and effect. But it strengthens the argument that a moderate intake of salt, 3 to 6 grams of sodium per day (7,5 – 15 grams of salt), may be best for many people. This matches what most people eat in developed societies.

Current official advice on low-salt diets may be misguided.

So if you like salt you may not need to worry about it too much. You might primarily want to keep your salt intake down if you have high blood pressure.
