Still, "while this is very interesting and promising research, [it] has to be looked at further," she said.
Dr. Gregg Fonarow, a spokesman for the American Heart Association and professor of cardiology at the University of California, Los Angeles, agreed.
"While it has been well-documented that diet can impact blood pressure, the lowering seen here is way out of proportion to what one might expect," he said. "One problem could be the study design, in which all the patients knew exactly what they were being given, which gives a little pause as to what these findings may mean."
"I would be cautious with any interpretation of these results, and I would certainly like to see them replicated independently," he added.
Data and conclusions presented at meetings should be considered preliminary until published in a peer-reviewed medical journal.
