Prevent Stroke with olive oil
Olive oil may reduce the risk of stroke in the elderly. Thus, the conclusion of a recent study conducted in three French cities in people aged 65 years and above were observed for an average of five years. The aging who regularly cook with olive oil or use it in salad dressings known stroke risk 41% lower than those who rarely eat them. From the observed 7625 senile, 148 people have a stroke in the study. Overall stroke rate was 1.5% in the olive oil users and 2.6% in non-users. The results are reported in the journal Neurology (15/06/2011).
Substitution effect?
Eating less saturated fat harmful improve users' health olive oil. As we know, other oils such as butter oil, sunflower oil and animal fats can increase the risk of stroke and other cardiovascular problems. Elements of olive oil itself, including oleic acid or polyphenols, also may hold secret protection effect, said Samieri. Polyphenols are antioxidant nutrients that reduce inflammation in the vascular system. Oleic acid, the main fatty acid in olive oil, contribute to lower bad cholesterol, which is harmful to the cardiovascular system.
Long before this study, the health benefits of olive oil are well known. In Finland, a public health program that began in the 90s has invited the public to use olive oil. As a result, 65% reduced incidence of stroke, heart attack reduced by 75% and 65% reduced cancer. An independent U.S. Food and Drug Administration (FDA) states that "the scientific evidence is limited and not conclusive suggests that eating about two tablespoons (23 grams) of olive oil daily may reduce the risk of coronary heart disease due to a single-chain unsaturated fat in it. To achieve these potential benefits, use olive oil to replace the same amount of saturated fat and not increase the number of calories you eat in a day. "

Low Density Lipoprotein (LDL)
In accordance with the terms penamaanya, LDL (low density liporotein) has less protein content and contains more cholesterol. In his travels throughout the body through blood vessels, cholesterol has a nature that is easy to stick to the walls of blood vessels.
When the process of attachment to the blood vessel walls accumulate, it becomes fatty plaque accumulation and the volume increased to constrict the flow of the blood vessels. When a flow in blocked blood vessels, a wide range of potentially fatal threat to attack the human body. Call them stroke, coronary heart disease and other even death. As a result, LDL cholesterol group today are familiar with the term 'the bad cholesterol'.
LDL cholesterol is the one that is touted as the ringleader of a variety of diseases that can be caused from the evils of cholesterol. 'Crime' thereof can have fatal consequences for the body.
However, not all cholesterol has a character that 'evil' as LDL cholesterol, the blood circulation there are HDL (high density lipoprotein). Cholesterol has a higher protein density has recourse nature of the circulatory function, which bind and bring LDL cholesterol that sticks to the walls of the blood vessels to continue the 'journey' through the body to become energy reserves as appropriate.
LDL cholesterol comes from the natural production by the body. Also, the body actually has the ability to meproduksi have appropriate levels of cholesterol it needs, but the result of the consumption of saturated fat, trans fat, can increase LDL cholesterol levels than normal.
When too much LDL cholesterol circulates in the blood, LDL will slow the formation of artery walls in a section that provides nutrition and oxygen to the heart and brain. Together with other substances, LDL will form plaque, which is a tough and thick deposits in the blood vessels which can cause constriction of the blood vessels and make them less flexible or not anymore. This condition is known as atherosclerosis. If there is a formation of clotting or coagulation of blood cells, then this will cause a blockage which resulted in a heart attack or stroke.
It is important to control LDL cholesterol levels remain low and increase the levels of HDL cholesterol to be free from the threat of hypercholesterolemia. How to control there is someone with the control diet and diet foods that have low fat content.
What is cholesterol?
Cholesterol is including fatty acids, this is one of the components of the fat itself. The presence of fat in our body itself actually has a function as a nutrient that is needed by the body in addition to other nutrients such as carbohydrates, proteins, vitamins and minerals.
Fats are energy reserves that contributed the highest calories. Cholesterol is often a scourge and are often discussed as a source of degenerative health problems today. However, it does not mean that cholesterol does not have the function of the human body.
In a variety of metabolic processes, cholesterol also play an important role include:
The process of formation of cells in the body, fat acts as forming cell walls.
It takes the basic material for the formation of steroid hormones.
Making bile acids for fat emulsion process.
Needed to make vitamin D, and also serves as an ingredient for making hormones - sex hormones and corticosteroids.
Mechanism of Cholesterol
Cholesterol itself is actually not very soluble fat in the blood. Because it is not very soluble in the blood, cholesterol need help to be able to circulate in the blood vessels of the body. Cholesterol in the blood is bound to a 'vehicle' called lipoprotein cholesterol that can help to circulate in the blood vessels of the body
In addition to its own production of the body, the body also get cholesterol from the foods we consume daily, especially egg yolks, shellfish such as shrimp, crab, offal (intestines, tripe, liver, spleen, brain, kidneys, and heart) as well as foods derived from milk (butter, cheese).
Cholesterol is produced in the liver as well as the surrounding 1gr/hari intestine will then circulate in the blood. In the content of the blood, cholesterol is bound by a lipoprotein substance, the substance is composed of:
chylomicrons, chylomicrons is a substance that has the function of bringing the energy in the form of fat to muscle.
VLDL (Very Low Density Lipoprotein), a substance that serves to bring the cholesterol that has been released by the liver to the tissues to be stored as energy reserves.
LDL (Low Density Lipoprotein),
IDL (Intermediate Low Density Lipoprotein), and
HDL (High Density Lipoprotein).
But unfortunately, in its function, cholesterol have a lower protein density (VLDL, ILDL, LDL) easy to stick to the walls of the coronary arteries, causing plaque (fatty deposits in the blood vessel wall is familiarly called atherosclerotic plaque).
If the blood vessels are blocked by fatty deposits, the impact of which is far more strokes, heart attacks, and other leading fatal to the human body. Therefore the LDL familiar today known as bad cholesterol designation.
While HDL cholesterol is caught being in a free state in the blood vessels to later carry over into the liver for further processing. Therefore, HDL cholesterol familiar regarded as good.
Indeed, the cholesterol we need is normally produced by the body is in the right amount. However, along with the existing arbitrariness diet, the amount to be far from a mere excess body needs.
The emergence of the amount of cholesterol is too high, due partly to overly excessive intake of foods derived from animal fats, eggs and foods, and today is known as junk food (junk food).
It is important to know more about the character of each lipoprotein were there to raise awareness of the importance of a healthy lifestyle that allows us to control and restrain the health status of our bodies.
Controlling Cholesterol in the Body
The ultimate goal of controlling blood cholesterol levels is to reduce LDL levels and increase HDL levels. Cholesterol is a fatty, not necessarily the most basic logic to control the fat content in the body is to limit the intake of fat contained in our diet everyday.
By controlling your diet, you already had a very good step to healthy living. Low-fat diet also benefits from keeping us safe from the threat of obesity.
Do not miss regular physical activity. Physical activity or regular exercise can help increase HDL levels. Olaharaga if done regularly, can help control diabetes, high blood pressure, and weight-all risk factors for heart disease.
In addition to regular sports activity, those who smoke, you have to and would not want to, and like it or not have to quit smoking. Because smoking can lower HDL levels and damage the walls of blood vessels thus increasing the potential for the accumulation of LDL cholesterol in the blood vessel walls, causing plaque deposits that could potentially be a blockage of blood vessels.
It's also important for us to keep an eye on cholesterol levels checked regularly. Thus, the movement of cholesterol in the blood can be monitored well
