A stroke is a major health concern in the United States, ranking among the leading causes of death and long-term disability. Each year, more than 795,000 people experience a stroke, and the fatality rate is so high, that in every three minutes, someone passes away. It is alarming, and one in four strokes are recurrent, which means it affects the individual more who have previously suffered from one. A recent study highlighted a potential intervention that could reduce the risk of recurrent strokes. This is by replacing regular salt with a potassium-enriched salt substitute. The research, published in JAMA Cardiology, suggests that this simple dietary switch may significantly lower stroke recurrence and related deaths. How Can Salt Substitute Lower Stroke RiskThe study, a subgroup analysis of the Salt Substitute and Stroke Study (SSaSS) examined over 15,000 participants with a history of stroke. It was conducted across 600 villages in northern China, and the research then followed the participants for fiver years. The participants who used the salt substitute composed of 75% sodium chloride and 25% potassium chloride experienced a 14% reduction in recurrent strokes and a 12% decrease in overall mortality. It also saw a drop in hemorrhagic strokes by 30%, while stroke-related deaths decreased by 21%. The researchers also found that using the potassium-enriched salt substitute did not significantly increase the risk of hyperkalemia (high potassium levels) making it a potentially safe option for many people. What Is The Science Behind It?Sodium intake plays an important role in blood pressure regulation, which is a major factor for stroke. This means that excessive sodium can lead to high blood pressure, which damages blood vessel walls over time, and increases the risk of blockages or ruptures that trigger strokes. When you replace sodium with potassium, it lowers blood pressure through two mechanism. The first one is when it reduces the overall sodium intake, which decreases vascular strain. Secondly, the added potassium has a vasodilatory effect, which helps the blood vessels to relax and improve circulation. Even a small reduction in blood pressure can have a significant impact. Research also suggests that lowering blood pressure just by 1mm Hg can reduce the chances of stroke by 5%. Potassium For Vascular HealthWhile salt substitute is a useful way to combat risk of heart stroke, experts also recommend to increase the intake of potassium-rich food in day to day diets. These include:Potatoes with skinTomatoesBananasAvocadosBeans and LentilsYoghurtLeafy greensUnsweetened dried fruitsThese foods not only help balance sodium and potassium levels but also provide fiber and other nutrients that support heart health. However, individuals with kidney disease or those on certain medications should consult a healthcare provider before increasing potassium intake.What Are The Other Ways To Reduce Your Sodium Intake?Season meals with herbs and spices instead of saltChoose fresh, whole foods over processed and packaged optionsOpt for “no salt added” or low-sodium products when shoppingCook at home to control sodium levels rather than relying on restaurant meals
