Foods rich in potassium improve women’s cardiac health

Cardiovascular diseases are the leading cause of death in the world. Les régimes riches en sodium augmentent le risk of hypertension and cardiovascular maladies. With the widespread consumption of processed foods, many people have limited sodium intake. Une étude vient de révéler that, chez les femmes, a regime riche en potassium can combat the effects of a regime rich in sodium and abaisser la tension artérielle. Chez les hommes, en revanche, a regime riche en potassium has no significant effect.

According to l’Organisation mondiale de la santé (WHO), les maladies cardiovasculaires (CVD) are the main causes of death in the world, with 17.9 million lives each year. The main risk factors are hypertension, hypercholesterolemia and smoking, but diet is also a contributing factor.

It is generally thought that a regime rich in sodium increases the risk of cardiovascular disease and arterial hypertension. Processed foods, particularly ultra-processed foods, often contain high levels of salt, the sort of thing for many people who control their sodium intake. A Dutch study, published in the European Heart Journal, revealed that women may be able to counteract the effects of sodium by adopting a potassium-rich diet, which could reduce the risk of CVD. Une grande cohorte bien mée, l’étude a été launched dans les années 90s, ce qui est loin d’être le cas aujourd’hui: Notre environnement alimentaire et les sources de sodium dans l’alimentation ont beaucoup changé depuis lors. Les authors reconnaissent également that le make de tirer une conclusion having a clinical impact à partir d’un écontillon d’urine de 24 heures constitutes an important limitation.

A plus marque effect chez les femmes

Large-scale cohort study of close to 25,000 participants in the UK EPIC-Norfolk trial. The participants were between 40 and 79 years old, the average age being 59 years for men and 58 years for women. At the start of the study, all participants completed a lifestyle questionnaire. The researchers then measured their blood pressure and took a urine sample. They estimated the dietary intake of sodium and potassium by measuring the urinary rates of these two minerals. Les chercheurs ont analysé l’effet de l’apport in potassium on the artérielle pressure, après avoir ajusté lâge, le sexe et l’apport en sodium.

Among women, they found a negative correlation between potassium intake and systolic arterial tension (SAS), plus the intake increases, plus the SAS decreases. L’effet était le plus important chez les femmes dont l’apport en sodium era le plus élevé. Chez les femmes ayant un apport élevé en sodium, each augmentation of 1 gram of daily potassium was associated with a baisse of 2.4 millimeters of mercury (mm/Hg) from SBP. A drop in TAS of more than 1 mm/Hg is not clinically significant in practice.

What it indicates, c’est ce l’apport en sodium n’est pas le seul facteur sur lequel nous devrions nous concentre pour preventer les MCV, and which des approches nutritionalnelles personalized are essentials for get des results optimaux in matter of santé », concluded Professor Spector, responsible for studies. The researchers found no association between potassium intake and blood pressure among men.

Foods rich in potassium

The WHO recommends that adults should consume 3,510 milligrams (mg) of potassium and no more than 2,000 mg of sodium per day. La plupart des adults currently consume trop de sodium
et trop peu de potassium dans leur alimentation.

Pour augmenter l’apport en potassium, une personne must include in his diet des aliments riches en potassium.

Parmi ceux-ci, citons

– les bananas
– les patates douces
– dried fruits, such as raisins, apricots and prunes
– les haricots, les pois et les lentilles
– les fruits de mer
– les avocats.

Professor Spector formulated advice in this sense: «I think that the advice we give is to increase whole vegetable foods naturally rich in potassium, such as avocados, legumes, artichokes, beetroots and apricots , et de minimiser les aliments ultra-transformés qui sont souvent très riches en sodium. »

Cardiovascular diseases

Les chercheurs ont suivi les participants après une durée médiane de 19.5 ans, les derniers enregistrements remontant à mars 2016. During this period, 55% were hospitalized or died due to cardiovascular disease. Les chercheurs ont recherché toute association entre le potassium alimentaire les cardiovascular events, après avoir contrôlée lâge, le sexe, l’indice de masse corporelle, l’apport en sodium, l’utilisation de médicaments hypolipidémiants, le bagisme, la consommation d’alcohol, le diabetes et les antécédents de crise cardiaque or d’AVC.

They found that, in the ensemble, the people with the highest potassium intakes had a 13% lower risk of cardiovascular events than those with the lowest intakes. Analysés séparément, les apports eléfêt en potassium reduisaient le risk de 7% chez les hommes et de de 11% chez les femmes. Dietary sodium did not influence the relationship between potassium and MCV.

The results suggest that potassium helps preserve heart health, but women benefit more than men. The relationship between potassium and cardiovascular events was similar to salt consumption, suggesting that potassium has other means of protecting the heart and increasing sodium excretion.

Another way to protect cardiovascular health?

Bien qu’un apport plus élevé en potassium ait eu le plus grand effet chez les femmes ayant un régime riche en sodium, le conseil actuel est de limiter l’apport en sodium. The reduction of sodium intake does not permit a single step to have a regimen that improves health, it simply tries to reduce the risk by suppressing a single component of the diet, which is too reductionist
