The research, published in The American Journal of Clinical Nutrition, compared the difference between eating a meal with 65 millimoles (mmol) of sodium and a low-salt meal of five mmol.
As part of the study 16 healthy participants were given a meal with 65mmol of salt (considered “typical” for a meal) and a meal with five mmol of salt on two separate occasions.
The paper says: “FMD was significantly more impaired after the high-salt meal (HSM) than after the low-salt meal (LSM) at 30 minutes and at 60 minutes.”
It concludes: “An HSM, which reflects the typical amount of salt consumed in a commonly eaten meal, can significantly suppress brachial artery FMD within 30 minutes.
