Women with normal blood pressure consuming the least amount of potassium—less than 1925 mg per day— were 32% more likely to have a stroke than women with normal blood pressure consuming more potassium than this after adjusting for multiple risk factors according to the 2014 Women’s Health Initiative Observational Study.
The risk of stroke in women with normal blood pressure was similar in each quarter of women consuming more potassium than this.
The second quarter of women with normal blood pressure who consumed 1925 to 2519 mg of potassium per day were 25% less likely to have a stroke during the 11 year follow-up than the one-quarter of women with normal blood pressure consuming the least potassium (less than 1925 mg per day).
The third quarter of women with normal blood pressure who consumed 2519 to 3194 mg of potassium per day were 25% less likely to have a stroke during the 11 year follow-up than the one-quarter of women with normal blood pressure consuming the least potassium (less than 1925 mg per day).
The quarter of women with normal blood pressure who consumed the most potassium—more than 3194 mg of potassium per day—were 21% less likely to have a stroke during the 11 year follow-up than the one-quarter of women with normal blood pressure consuming the least potassium (less than 1925 mg per day).
