Randomized trial shows high potassium diets decrease stroke deaths in hypertensive rats, suggesting ancient dietary benefits.

This research examines the protective effects of high potassium diets against stroke deaths and kidney disease in hypertensive rats.
Male spontaneously hypertensive stroke-prone rats were fed either 0.75% or 2.11% potassium diets for 8 months.
Mortality rates, blood pressures, and brain infarcts were measured and compared between diet groups.
Dry weight of mesenteric arterioles was assessed to evaluate hypertensive hypertrophy.
On the normal potassium diet (0.75% K), 69% of rats died, compared to only 2% on the high potassium diet (2.11% K), p<0.00001.
A matched group comparison showed a 91% reduction in mortality from 64% to 6%, p<0.0001, with high potassium diets.
Brain infarcts were significantly lower with high K diets, showing a 94.5% reduction, from 36% to 2%, p<0.0001.

Louis Tobian (1986) studied this question.
