Consume this food claimed to counteract high blood pressure, specifically targeted at women
In a groundbreaking study involving nearly 25,000 participants aged between 40 and 79, researchers have uncovered a significant connection between potassium consumption and blood pressure. The study, which was followed up for 19.5 years, revealed that this link is present regardless of salt intake [1].
The study, led by Professor Liffert Vogt and his research team, has shed light on the role of potassium in maintaining healthy blood pressure levels. The mineral helps the body excrete more sodium in the urine, thereby reducing blood pressure [2].
Intriguingly, the benefits of potassium were most evident in women who consumed high amounts of salt. High salt consumption, associated with elevated blood pressure and a raised risk of heart attacks and strokes, seemed to be countered by an increased intake of potassium [3].
For every one gram increase in daily potassium, women benefitted from a 2.4 mmHg lower systolic blood pressure [4]. After adjusting for confounding factors, people who consumed the most potassium had a 13 percent lower risk of cardiovascular events [1].
Professor Vogt suggests that potassium plays a crucial role in preserving heart health, but women seem to benefit more than men [5]. The relationship between potassium and blood pressure has been a subject of interest for researchers, and this study adds to the growing body of evidence supporting the importance of potassium in maintaining cardiovascular health.
Potassium offers other ways of protecting the heart as well. A high sodium diet can negatively impact the body's production of nitric oxide, a molecule that helps dilate blood vessels. By promoting the excretion of excess sodium, potassium helps maintain optimal levels of nitric oxide, further contributing to blood pressure control [2].
Incorporating potassium-rich foods into your diet is a practical way to boost your intake. Some examples include avocados, salmon, potatoes, sweet potatoes, pumpkin, dark leafy greens, and asparagus. Even green bananas have a special added benefit due to their high resistant starch content, which increases potassium absorption [6].
In conclusion, for women (and generally), raising potassium intake is a vital complementary strategy to reducing sodium for better blood pressure control, especially in the context of high salt consumption. This approach helps relax blood vessels and flush excess sodium, contributing to improved cardiovascular health and decreased hypertension risk [1][2][4].
