A 400 mg increase in daily potassium intake was associated with a 40% reduction in the risk of stroke-associated death during a 12 year follow-up according to a 1987 study which followed 859 men and women, aged 50 to 79 years, in Southern California.

In the one-third (1/3) of people consuming the least amount of potassium, stroke mortality was

• 2.6 times higher in men and
• 4.8 times higher in women

compared to the two-thirds (2/3) of people consuming the most potassium.

(Unfortunately, I do not know the potassium intake of these groups because I do not have a copy of the paper.)
