Voedingsadvies El MondoResearch Question:
Prospective cohort studies have the relationship between the daily intake of potassium and the incidence of cardiovascular diseases examined but their results are not entirely consistent. It was therefore carried out this review article.
The daily intake of potassium lowers the chances of getting heart disease?
Study Design:
This overview article contained 15 cohort studies with an average follow-up time of 12.2 years (5 to 19 years). The studies 247510 male and female participants, of which knew 7066 cases with stroke and 3058 cases with heart disease.
The potassium intake was obtained by 24-h dietary recall (n = 2), food frequency questionnaire (n = 6) or 24-hour urine (n = 3).
There was a significant heterogeneity between the studies and no question of publication bias.
Results and conclusions:
A pooled analysis showed that 1.64 g of potassium per day the chance of getting a stroke significantly reduced by 21% [95% CI = 0.68-0.90, p = 0.0007]. Significant is, there is a link at a 95% reliability.
A 21% significant reduction leads to a reduction in annual worldwide 1155000 death cases caused by a stroke.
There was a non-significant trend of a reduced risk of getting heart disease to spot. Non-significant is, there is no link to a 95% reliability.
The researchers concluded that a high potassium intake (1.64 grams per day) reduced the chance of getting a stroke and possibly the chance of getting heart disease.
