Normal blood pressure in adults is below 120/80 mmHg. One of the most important things to do when controlling blood pressure is to reduce the amount of salt in your diet. However, in some cases, even if you reduce the amount of salt, your blood pressure may still be high.
Blood pressure index reflects the force of blood on the blood vessel walls when the heart contracts and when the heart rests between beats. When blood pressure rises above normal levels, especially from 130/80 mmHg or higher, the vessel walls must bear greater pressure, causing the cardiovascular system to overload, according to the health website Healthline (USA).

This condition, if prolonged, can damage the lining of blood vessels, promote atherosclerosis, and reduce blood flow to the heart, brain, and kidneys. The risk of stroke, myocardial infarction, heart failure, aortic dissection, and kidney failure increases significantly with the degree of hypertension. Therefore, blood pressure control is very important for health.
However, many people still have high blood pressure despite limiting salt in their diet. In these cases, the root cause is likely insulin resistance.
The main function of the hormone insulin is to bring glucose into cells so that the cells can use it for energy. When insulin resistance occurs, the cells need more insulin to absorb glucose.
The pancreas responds by secreting more of the hormone insulin, which can lead to a number of health problems. The kidneys retain sodium and water instead of excreting them, which increases blood pressure. Blood vessels constrict, creating extra pressure in the vessel walls.
Additionally, increased insulin also causes chronic inflammation in the arteries, which is a risk factor for heart disease. Without addressing insulin resistance, medications and a low-salt diet can only mask the symptoms.
To truly lower blood pressure, metabolic health must come first. In addition to limiting salt, people with high blood pressure also need to prioritize healthy proteins, fiber, and limit refined sugars and foods high in white starch.
In particular, they need to exercise regularly. Regular exercise increases insulin sensitivity, controls blood sugar and reduces blood pressure.
In addition, patients also need to get enough sleep and control stress. These are all factors that affect hormonal balance. These changes, although slow, need to be consistent and maintained as habits. They can bring better results than instant solutions, according to Healthline.
