After eating a high-salt diet for several weeks, older female rats with high blood pressure had similar blood pressure levels as those on a low-salt diet, around 178 mm Hg in both groups.

Scientific Claim

In 20-month-old female spontaneously hypertensive rats, mean arterial pressure does not significantly change with a high-salt diet (8% NaCl) compared to a low-salt diet (0.3% NaCl), with measurements of 178±5 and 178±4 mm Hg (p=NS).

Original Statement

“MAP was not salt sensitive (C+T: 178±5; HSD+T: 178±4 mm Hg, p=NS)”

Similar Assertions

In older female rats with high blood pressure, starting blood pressure was similar whether they ate a normal low-salt diet or a high-salt diet, with numbers around 174 and 168 mm Hg.

99%

Giving a common antioxidant drug called Tempol to older female rats with high blood pressure did not lower their blood pressure, whether they ate a low-salt or high-salt diet.
