Prevention of heart disease

Prevention of cardiovascular disease:

Prevention of heart disease, protection against infection and prevention of diseases in general are all related to keeping the blood healthy. So here I will explain how blood plays an important role in the prevention of diseases and the protection against infection.

At the end I will give you advises on how to keep your blood healthy.

Foreign organisms such as bacteria may enter the body through the lining of the respiratory system, through the alimentary canal and through breaks in the skin. Many of these organisms are pathogens, i.e. capable of producing disease. Blood has several components which protect the body from infection:

• (a)White corpuscles – those white corpuscles that are amoeboid are sometimes called phagocytes, i.e. they are capable of ingesting living bacteria, dead cells and other foreign particles in the blood and tissue fluid spaces; they do this rather as Amoeba ingests its food.
• (b)Antibodies – these are complex blood proteins found in the plasma. They are almost certainly secreted or stored by those white corpuscles that are formed in the lymph system. Antibodies are said to act against pathogens in the circulation in three main ways:
• (c)Antitoxins – these are a special type of anti-body. They are secreted into the plasma but act against the excretions of pathogens rather than against the pathogens themselves. These excretions are called toxins; they are largely responsible for the characteristic symptoms (fever, rash, etc.) of a particular disease. Each type of bacterium produces a different toxin, which can be neutralized by a specific anti-toxin. Where an infection is extensive, e.g. at a septic cut, bacteria at first outnumber the white corpuscles; the bacteria secrete toxins which kill large number of white corpuscles. The dead corpuscles accumulate and form pus.
• (d)Clotting – this process prevents excessive loss of blood when blood vessels are damaged. It is extremely complex, but the essential stages are as follows:
  1. When the skin is cut and blood flows out, the platelets become exposed to the air; they disintegrate and liberate an enzyme thrombokinase into the plasma. Apparently some thrombokinase is also set free from the damaged blood vessel walls.
  2. Thrombokinase in the presence of calcium ions, found in blood, can now change the plasma protein prothrombin to an active enzyme thrombin.
  3. Thrombin reacts with the soluble plasma protein fibrinogen and changes it to insoluble fibrin which is precipitated as strands in a meshwork.
  4. Corpuscles become trapped in the mesh, dry, die and harden to form a scab under which the wound can heal and which prevents entry of foreign particles.
     (the blood of people who suffer from the hereditary disease haemophilia lacks substances necessary to complete the clotting process.)
• (e)Inflammation – where part of the body becomes infected, e.g. when a wood splinter is left in the skin, the blood vessels may dilate. More warm blood reaches this part: the local rise in temperature kills many bacteria. At the same time, the blood capillaries become increasingly permeable, allowing antibodies and white corpuscles to reach the infected part more easily.
• (f)Immunity – pathogens liberate protein substances called antigens into the bodies of the organisms which they invade. Each type of pathogen produces its own special type of antigen, and this provokes the production of a specific antibody against it.The first time that a person is infected by a particular pathogen (even if the infection is not sufficient to produce disease symptoms), specific antibodies are manufactured in response. Normally, its various protective activities (inflammation, the activities of white corpuscles, and the formation of antibodies and antitoxins) enable the person to survive. Afterwards , some of the specific antibodies remain in the person, which somehow ‘remembers’ how to make them – the ability to form the particular anti-body is even passed on the daughter cells after cell division. In any subsequent infection of the same type, specific antibodies will be readily available to deal with it. Because of this, it is rare for anyone to suffer from measles, mumps or chickenpox more than once.This process is called natural immunity, because it has not been brought about by medical treatment. (Many viruses, such as those that cause colds and influenza, exist in different forms called ‘strains’; although a person may develop natural immunity from several of these strains, other ‘new’ strains can cause disease symptoms.)

Advises on how to keep your blood healthy.

Since your blood is everywhere in your body, keeping it healthy is of upmost significance. The first advice that I will give you is of general nature, that is eat healthy. To be more specific I will say:

1. Drink much water every day.
2. Drink one liter of water in the morning on empty stomach.
3. Don’t smoke.
4. Eat healthy (less fat, less sugar, less salt, more fruits & vegetables).
5. Drink a class of warm water, 20 minutes after every meal.
6. Don’t drink cold water (or any other beverages which are cold)
7. Don’t drink alcoholic drinks.
8. Don’t drink cold drinks and juices that have too much sugar.
9. Perform regular physical exercises (minimum 30 minutes’ walk daily)
10. Perform some form of meditation daily for at least 15 minutes.
