After eating a high-potassium meal, people with controlled high blood pressure may have slightly better blood vessel relaxation two hours later, but this difference isn't strong enough to be considered statistically significant.

Scientific Claim

Treated hypertensive patients show a non-significant trend toward higher radial artery flow-mediated dilation (5.2% vs 3.9%, p=0.07) after a high-potassium meal (2278 mg) compared to a low-potassium meal (530 mg) at 120 minutes postprandial.

Original Statement

“at 120 min, FMD tended to be higher in participants after the high K+ meal (5.2 ± 4.1%) than after the low K+ meal (3.9 ± 4.1%) (p = 0.07).”

Assessment Explanation

The claim correctly uses 'non-significant trend' to describe the p=0.07 result, avoiding definitive language for a non-significant finding.

Similar Assertions

For people with controlled high blood pressure, eating a meal with lots of potassium doesn't change how well their blood vessels relax at the start of the meal compared to a meal with less potassium.

92%

Eating meals with different potassium levels doesn't change the size of the radial artery or how much blood flow increases after a temporary blockage in people with controlled high blood pressure.

79%

Two hours after eating a high-potassium meal, people with controlled high blood pressure have slightly higher diastolic blood pressure compared to a low-potassium meal, though the difference is small.

75%

When people with controlled high blood pressure eat a meal high in potassium, their blood potassium levels go up significantly compared to a low-potassium meal, especially within an hour and two hours after eating.

74%

One hour after eating a high-potassium meal, people with controlled high blood pressure have higher blood fat levels compared to a low-potassium meal, which is a statistically significant difference.
