- Heart problems is the main reason behind demise worldwide.
- Diets excessive in sodium improve an individual’s danger of hypertension and heart problems.
- With the widespread consumption of processed meals, many individuals discover it onerous to restrict their sodium consumption.
- Now, a examine has discovered that, for girls, a potassium-rich weight loss plan might fight the consequences of a excessive sodium weight loss plan, and decrease blood strain.
- In males, nevertheless, a potassium-rich weight loss plan had no vital impact.

A weight loss plan excessive in sodium is extensively believed to
A examine from the Netherlands, printed in European Heart Journal, has discovered that girls might be able to fight the consequences of sodium by consuming a potassium-rich weight loss plan, probably reducing their danger of CVD.
Prof. Tim Spector, co-founder of ZOE, instructed Medical Information Right now:
“Nicely-conducted and huge cohort — [the study was started] within the 90s which is definitely fairly a very long time in the past now: Our meals surroundings and sources of sodium within the weight loss plan have modified quite a bit since then. The authors additionally acknowledge that drawing a clinically impactful conclusion from one 24-hour urine pattern is a severe limitation.”
The massive-scale examine took virtually 25,000 contributors from the EPIC-Norfolk study within the U.Ok. Contributors ranged in age from 40 to 79, with imply ages of 59 for males and 58 for girls.
At the beginning of the examine, all contributors stuffed out a life-style questionnaire. Researchers then measured their blood strain and picked up a urine pattern. They estimated dietary consumption of sodium and potassium ranges by measuring urinary ranges of those two minerals.
Researchers analyzed the impact of potassium consumption on blood strain, after adjusting for age, intercourse and sodium consumption.
In ladies, they discovered a damaging correlation between potassium consumption and systolic blood strain (SBP) — as consumption elevated, SBP decreased. The impact was best in these ladies who had the very best sodium consumption.
In ladies with a excessive sodium consumption, each 1 gram improve in day by day potassium was related to 2.4 millimeters of mercury (mm/Hg) decrease SBP.
“Decreasing the SBP by simply over 1 mm/Hg isn’t clinically vital in observe. What it does point out is that sodium consumption alone isn’t the one issue we ought to be concentrating on when stopping CVD, and customized vitamin approaches are key in attaining optimum well being outcomes,” famous Prof. Spector.
The researchers discovered no affiliation between potassium consumption and blood strain in males.
To extend potassium consumption, an individual ought to embrace meals which might be excessive in potassium of their weight loss plan.
- candy potatoes
- dried fruits, comparable to raisins, apricots and prunes
- beans, peas and lentils
Prof. Spector provided comparable recommendation, saying: “I believe the recommendation we ought to be giving is to extend complete plant meals, naturally excessive in potassium, comparable to avocados, legumes, artichokes, beets and apricots, and reduce ultra-processed meals which are sometimes very excessive in sodium.”
The researchers adopted up with contributors after a median of 19.5 years, with the final recordings in March 2016. Throughout this time, 55% have been hospitalized or died attributable to CVD.
The researchers seemed for any affiliation between dietary potassium and cardiovascular occasions, having managed for age, intercourse, physique mass index, sodium consumption, use of lipid-lowering medicine, smoking, alcohol consumption, diabetes and prior coronary heart assault or stroke.
They discovered that, general, these with the very best potassium consumption had a 13% decrease danger of cardiovascular occasions than these with the bottom.
When analyzed individually, excessive potassium consumption decreased the lads’s danger by 7%, and the ladies’s by 11%. Dietary sodium didn’t affect the connection between potassium and CVD.
“The outcomes recommend that potassium helps protect coronary heart well being, however that girls profit greater than males. The connection between potassium and cardiovascular occasions was the identical no matter salt consumption, suggesting that potassium has different methods of defending the center on high of accelerating sodium excretion,” explains examine creator Prof. Liffert Vogt, from Amsterdam College Medical Facilities within the Netherlands.
Though larger potassium consumption had the best impact in these ladies with a high-sodium weight loss plan, present recommendation is to restrict sodium consumption.
“Decreasing sodium consumption alone doesn’t permit for a weight loss plan which improves well being, it merely tries to cut back danger by eradicating a single element of meals, which is simply too reductionist,” mentioned Prof. Spector.
“The salt discount program within the U.Ok. launched practically 20 years in the past has helped lower salt content material in processed meals however CVD prevalence has proven little proof of change — decreasing sodium consumption isn’t the magic bullet within the struggle in opposition to CVD,” he identified.
So, maybe—notably for girls—rising the consumption of potassium-rich meals may very well be an efficient technique to try to defend cardiovascular well being.
