High Blood Pressure: The Silent Killer in Every Family
High blood pressure is a leading cause of cardiovascular-related deaths globally. According to statistics from the Vietnamese Ministry of Health, approximately 30% of adults suffer from this condition without even knowing it. What’s frightening is that it often exhibits no clear symptoms, but can lead to stroke, kidney failure, heart attack, or even sudden death.
Ms. Hanh (45 years old, Hanoi) used to think she was healthy because she didn’t experience dizziness or fatigue. However, during a routine check-up, her doctor warned that her blood pressure was higher than normal. “I was shocked to learn that I was at risk of a stroke. Since then, I’ve changed my diet, especially by incorporating more green vegetables and fruits,” she shared.
Bananas and Broccoli: Superfoods for a Healthier Heart
A new study by the University of Waterloo, Canada, has revealed a surprising finding: increasing the ratio of potassium to sodium in one’s diet can be more effective in regulating blood pressure than simply reducing salt intake.
Professor Anita Layton, a leading expert in physiological modeling, commented, “Usually, we only think about reducing salt, but in fact, adding potassium-rich foods like bananas and broccoli can have a more positive impact on blood pressure.” (Source: ZingNews.vn citing Mirror)
Potassium plays a crucial role in maintaining electrolyte balance, regulating blood vessel contraction, reducing water retention, and supporting stable heart function. In contrast, sodium (salt) increases blood volume, overworking the heart and leading to high blood pressure.
Why Modern Diets Are Making Us Sick
In the past, our ancestors consumed large quantities of fruits and vegetables, which are natural sources of potassium. However, the modern Western diet is characterized by an abundance of fast food, processed meals, excessive sodium, and a lack of potassium.
Melissa Stadt, a researcher at the University of Waterloo, explained, “The human body has evolved to function optimally on a potassium-rich, sodium-poor diet. This reversal is contributing to high blood pressure becoming a prevalent disease in industrialized nations.” (Source: Vietnamnet.vn)
The study also revealed an interesting fact: men are at higher risk of high blood pressure than premenopausal women, but they also respond better to an increased potassium-sodium ratio.
How to Incorporate Potassium into Your Daily Diet
You don’t need to search for expensive foods. Bananas, broccoli, sweet potatoes, spinach, oranges, and lentils are all potassium-rich “superfoods” easily found in markets or supermarkets.
Nutritionist Nguyen Thi Lam, former Vice Director of the National Institute of Nutrition, advised, “Adults should consume approximately 3,500-4,700 mg of potassium daily. Incorporating a variety of fruits and vegetables into your meals helps regulate blood pressure and supports heart health, digestion, and weight maintenance.” (Source: VnExpress.net)
It’s important to note that you should not supplement potassium with medication without a doctor’s recommendation, especially if you have kidney issues.
