The effect of diet on blood pressure
One of the first things you should change your lifestyle if you have been diagnosed with high blood pressure is a change in your diet. Many people can control your blood pressure problems almost entirely with dietary restrictions. However, many do not know why they have to make these changes. Sometimes this lack of knowledge can lead to demotivation to make the necessary changes. Understanding how the foods we eat affect blood pressure begins with understanding what is blood pressure.
What is blood pressure?
Blood pressure is the force exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. High blood pressure (also called hypertension) occurs when blood moves through the arteries at a higher pressure than normal producing a voltage in the blood vessels, arteries and heart. Hypertension usually has no symptoms, but can cause serious problems such as stroke, heart failure, myocardial and renal failure. Few people know what really causes high blood pressure, but can be treated with changes in diet.
The effect of salt on blood pressure
Salt is the main culprit when it comes to foods that increase blood pressure. Foods that are high in salt are also high in sodium. Sodium has the ability to absorb water. The normal volume of blood plasma of an individual can increase considerably when consumed a diet rich in sodium. This increased amount of blood flowing through the inside of the arteries produces a pressure against its walls increasing blood pressure.
The effect of fat and calories in blood pressure
A heart – healthy diet is one that is low in fat and calories. Fats and calories do not directly affect blood pressure, but if they do so indirectly. A diet high in fat and calories will make most people gain weight. Being overweight is a risk factor for high blood pressure. The heart works forced and more if there is a risk of cholesterol and / or triglycerides.
All these factors (obesity, hypertension, high cholesterol and triglycerides, genetic predisposition) make increase the risk of more severe coronary complications galleys. Studies have shown that the loss of 5 kilos drastically reduce blood pressure for those who have been diagnosed with hypertension.
The effect of alcohol and caffeine on blood pressure
A study by researchers at the department of social medicine at the University of Bristol (UK) shows that drinking alcohol can increase blood pressure more than thought, even among those who drink in moderation. Scientists say that the risk is doubled among regular drinkers. In addition, alcohol contains empty calories that can increase the weight.
Caffeine is another food that causes increased blood pressure, even for those who have no blood pressure problems. Caffeine works by stimulating the heart, increases the heart rate, contraction force and also increases blood pressure transiently. This increase in blood pressure is particularly dangerous for people who rarely consume caffeine because blood pressure peaks can be very high for these people.
