Understanding High Blood Pressure
High blood pressure (hypertension) occurs when the force of your blood against artery walls is consistently too high. Over time, this can damage your arteries and vital organs.
Key Facts:
Normal BP: Less than 120/80 mmHg
Stage 1 Hypertension: 130-139/80-89 mmHg
Stage 2 Hypertension: 140+/90+ mmHg
Causes:
Poor diet (high in sodium and processed carbs)
Obesity
Lack of physical activity
Chronic stress
Excessive alcohol and smoking
How Diet Affects Blood Pressure
Diet plays a crucial role in regulating blood pressure. Foods high in sugar, refined carbs, and sodium can contribute to insulin resistance, weight gain, and stiffened arteries—factors that increase the risk of hypertension. By making mindful food choices, you can directly influence your cardiovascular health.
