Causes of high blood pressure

Raw (about 30% of people with hypertension are unaware of being infected), it can damage your organs and even the development of other potentially life-threatening diseases, including stroke, heart disease and renal failure.

Hypertension occurs when the body retains too much water, which increases the volume of blood to the heart, arteries and veins of our increasing pressure from the walls of the heart and blood vessels. Sometimes the heart beats too heavy and can also increase the pressure. Either situation leads to high blood pressure, to compensate the blood vessels of the time.

Blood pressure is measured in millimeters of mercury (mm Hg), when the amount of air pressure must be a column of mercury 1 mm high support. Blood pressure has a number of systolic and diastolic. Your systolic blood pressure, the pressure in the vessels when the heart beats, should offer less than 140 mm Hg your diastolic pressure, the pressure between the heart, must be less than 90 mm Hg

Like heart disease, hypertension is a disease of modern civilization. Hypertension is a product of how our bodies over the centuries, developed the ability to retain water and avoid dehydration. We tend to retain salt (sodium chloride or NaCl), since before modern times, salt was relatively rare. When the salt is maintained in the blood vessels, it is important that the water from the so-called osmotic effect, and therefore water is not eliminated, as would otherwise be the case through the kidneys and excreted in urine.

Not granted, all are sensitive to salt in the same way. However, there is no doubt that the general population to eat more salt than before, probably at least two or three times, and what are the patterns of negative effects on our health, including increased blood pressure.

Since the first people can not easily get the salt will not go out to eat very salty potato chip, and the pressure of blood on the ceiling. Indeed, the excretion of salt was an important goal of early humans - that was a good thing, if you lived in Savannah and would not eat or drink for several hours. It is bad if you live in America in the 21st century, and eat fast food three times a day.

The elderly also have more exercise, eat less food in general (), not by choice, and not to smoke, use drugs or alcohol to drink. However, these difficult circumstances lead to more infections, and when eaten by tigers and rocks falling hazards in the workplace of primitive man. Fortunately, these people are not worried, even on blood pressure, zoom after eating a hamburger and fries.

Cheeseburger despite our need for salt as soon as possible, we have developed a taste for salty foods, never lost. The salt enhances the flavor of other foods, and many chefs believe that it is an essential ingredient in the kitchen. Salt your pasta water with a handful of salt does not cause high blood pressure. Most salt in our system comes pre-processing, packaging and more) of frozen foods (except flash-frozen fruits and vegetables we eat, and salt in restaurant and fast food. Food Processors use large quantities of salt to food to improve flavor to hide the absence of other natural flavors, and act as a preservative. Watch a food label, and you will find astronomical levels of salt in the diet - often more than 25% of one portion. The best way to avoid excess sodium in foods is to buy fresh, unprocessed whole foods and prepare your own meals. If you buy canned beans and vegetables, low in sodium, should be flushed about 40% sodium.
