Taylor tells the Health Blog that he doesnâ€™t question the notion that salt consumption is linked to cardiovascular risk. But he says giving individuals dietary advice alone isnâ€™t likely to cut it as a means of permanently lowering their salt intake, and therefore isnâ€™t likely to have a long-term impact on health outcomes. â€œWhatâ€™s not working is the advice,â€ he says.
On the other hand, many studies comparing how much salt people consume with their incidence of cardiovascular disease have come up with clearer links. A 2009 meta-analysis3 of 13 such studies, incorporating 177,000 patients, found that a high-salt diet increased the risk of stroke by 23%.
