Salt restriction does not lower blood pressure variability

Urinary sodium excretion and salt intake are not independently associated with 24-hour blood pressure variability (BPV), according to a study.

Tan Lai Zhou and colleagues used data from 2,652 participants in the Maastricht Study to evaluate whether urinary sodium excretion and salt intake are associated with 24-hour BPV. Participants adhered to a seven-day low- and high-salt diet (50 and 250 mmol NaCl/24 hour, respectively) with a washout period of 14 days.

The researchers found that 24-hour urinary sodium excretion was not associated with 24-hour systolic or diastolic BPV (β, per 1 g/24-hour urinary sodium excretion: 0.05 mm Hg [95 percent confidence interval, −0.02 to 0.11] and 0.04 mm Hg [95 percent confidence interval, −0.01 to 0.09], respectively). There were no significant differences observed in mean difference in 24-hour systolic and diastolic BPV between the low- and high-salt diet (0.62 mm Hg [95 percent confidence interval, −0.10 to 1.35] and 0.04 mm Hg [95 percent confidence interval, −0.54 to 0.63], respectively).

"Our results do not indicate that salt restriction would be an effective strategy to lower BPV," the authors write.

Also, you have to consider everything else that is in BBQ sauce, such as the truckload of sugar. Sugar can spike blood pressure when your body deals with the emergency of spiking blood sugar.

In the event these people actually sweat, they should lick their arm. It will taste salty. The body has always been able to easily rid itself of excess salt.

Thanks C.M.! I do need to watch BP, but always thought it had more to do with Sodium/Potassium levels. (It will rise if I overdose on Salt though!)
