Cardiovascular disease is a word that encompasses a wide spectrum of diseases and conditions, the cardiovascular system. It may also include the hardening and stiffening of the arteries, called atherosclerosis, which chlolesterol deposits that are in our arteries, a condition known as artherosclerosis, and a number of resulting problems such as heart attacks, blood clots, stroke, poor blood circulation and gangrene.

This variety of conditions and diseases is creepy enough, a fear of the prospect of old and poor weight gain or develop high blood pressure and high cholesterol levels, two of the pre-marker of potential cardiovascular disease.

There are a number of theories about the cause of the disease ranged widely. Some attribute it to the trunk and emotions such as anger and fear. Others believe that cardiovascular disease is caused by too much low-density lipoprotein or bad cholesterol and not enough high density lipoprotien or good cholesterol. This was the dominant theory for years, and it has been linked to cardiovascular disease, but in the last forty years there has been growing evidence for another cause of cardiovascular disease, homocysteine.

Homocysteine is the product of the distribution of proteins, we take in our food. Normally, the body with a vitamin known as folic acid to help connect these in a different form, such as methionine. In some cases, not enough folic acid in the system for the conversion of homocysteine, or it is another problem hampering the conversion. This leads to a body of homocysteine in the blood.

Homocysteine is toxic to the lining of blood vessels. A structure of IT in the blood can lead to scarring of the inside of blood vessels. For a long time this scarring may lead to stiffening and hardening of the arteries, and it may even damage the heart. Does this sound familiar? It should. This stiffening of blood vessels is almost exactly like the description of atherosclerosis.

Research has found that patients with atherosclerosis have elevated homocysteine in the blood. And an estimated ten percent of the risk of cardiovascular disease from 1999 was due to elevated homocysteine levels. There are a number of studies that link elevated homocysteine levels to heart disease. A study published in 1995 showed that there was a forty percent increased risk of heart disease Arteriosclerotic increase for each of four micromoles per liter of homocysteine in the blood.

A chronic shortage of low levels of folic acid may possibly drastic and long-term consequences such as homocysteine in the blood continue to build or damage to the lining of blood vessels. The recommended daily intake of folate for adults is four hundred mcg. This amount of folic acid can be taken in by the consumption of a lot of dark green green vegetables, fortiefied breakfast cereals and other foods with folic acid. By ensuring that a minimum amount of folate in the diet every day, it is possible to reduce the risks of developing cardiovascular disease.
