Effect of Tea Consumption Health : Tea and heart

Effect of tea's health benefits have been demonstrated in the experimental studies using animal and some human studies. Two of the most intensively investigated is the heart disease and cancer.

Although the mechanism Protective activity of tea against the disease has been proposed, there are inconsistencies in the relationship between tea consumption and risk of disease in humans.epidemiologik have been many studies investigate the effects of tea consumption kardiovaskuler disease. On a long-term study in the Netherlands, tea consumption associated with a lower risk of death due to coronary heart disease and stroke incidence is low.

In the study in Rotterdam, a best tea consumption with illness aterosklerosis aortik has been in the observation. Health study in Boston found that subjects who drank a cup (200-250 ml) or more of black tea per day had approximately half the risk of a heart attack compared with people who do not drink tea.

One mechanism proposed for Protective effects of tea that may be against the disease kardiovaskuler is that tea polifenol prevent oksidari LDL, known to be involved in the development of aterosklerosis.

Studies have indicated that consumption of black tea has an LDL against oxidation ex vivo. Polifenol the accumulation of LDL particles in the 3 days after consumption of green tea or black, but their level is not enough to strengthen the resistance of LDL oxidation.

Summary of hipokolesterolemik tea can also contribute to protection against heart disease. In the animals that were given feed and high-fat cholesterol, green tea, black tea, and tea have been polifenol prevent lipida increased serum and liver, have lower total serum cholesterol or aterogenik index, and have increased ekskresi fekal from lipida and total cholesterol.

When the animal is given a high fat feed, the animal is given a green tea or green tea plifenol have serum total cholesterol and low-level triasilgliserol but ekskresi fat fekal is higher than the control group.

However, the study and test epidemiologik in humans have failed to show an effect of lowering serum cholesterol consumption of green tea or black. Epidemiologik of 13 studies, only four reported the inverse relationship. One other potential mechanism may be through the effect on body weight and fat.

Latest observation that administration of black tea has intragastrik prevent platelet aggregation and prevent thrombosis koronari was experimental and that the dog polifenol green tea consumption has been decreasing platelet aggregation terinduksi of ADP that provides a mechanism for the possible prevention of disease kardiovaskuler. However, green tea extract equivalent to 10 cups (2 liters) tea for 4 weeks has no significant effect on several indicators related to disease kardiovaskuler.

Black and green tea has caused a large increase in acute (30 minutes after ingesti) on blood pressure than caffeine alone. However, regular tea consumption does not change blood pressure.

Deviation can result in Fatal Blood on the Baby

High degree of bilirubin in the blood called hiperbilirubinemia (hiper = excessive, bilirubinemia = bilirubin in the blood), is the result of the rupture of red blood cells. Excessive bilirubin in the blood will cause a yellow color on the surface of the skin so that people know the term jaundice.

In the normal person in the wall there is a red blood cell enzyme G6PD (glucose-6-phospat dehidrogenase) that function to maintain red blood cell wall that is not easily broken when exposed to material that is oksidatif. For example: camphor (containing nafthalen), peanut koro, the sulfa drugs, antibiotics chlorampenicol, antimalaria drugs, the nitrofurans, febrifuge the phenacetin and asetanilid, vitamin K3, vitamin C and high doses.

Contact with materials or drugs can occur through the food / beverage, respiratory, or through the skin. daughter because the mother suffered from lack of blood cell G6PD so easily broken red that may be caused by exposure to the materials above. Because blood cells red broken polynomial, baby mother is also lack of red blood cells so that the body appears pale. G6PD deficiency disease is a genetic / decrease and will suffer for life. Deviation is more established in the gender of men and found in many Asian, Middle Eastern, and Mediterranean. In the new born baby when the value exceeds the limit of normal bilirubin can penetrate the network and the brain that cause permanent brain damage. Finally, the baby will die or disabled for life.

While this treatment has not been found because the specific genetic on. It is therefore important that businesses prevent. In the new born baby, clothes, bed mother and the baby, do not be camphor, this is usually because of factors as and Avoid contact with the materials described above.

In the children of the G6PD deficiency if the drinking or contact with materials, blood cells are broken red will arise so that lack of red blood cells (anemia) from a light to heavy. Is suportif are intended to lower the bilirubin level in blood so it does not enter into the brain network.

To lower the bilirubin level can be used radiotherapy. This is very effective without any side effects. When therapy with radiotherapy kadar bilirubin tended to increase, if possible exchange transfusion can be done. This means the baby is removed blood was replaced with donor blood.

We suggest that the whole family descended from the father and mother to be G6PD for the possibility of this disease so that it can be anticipated. Very be pitied because Indonesian does not know all of the blood, let alone know the difference G6PD this.

Coffee and High Blood Pressure

One of three Americans is affected by high blood pressure, a recognized risk factor for heart disease and stroke. It's well-known that the caffeine in coffee can cause a rise in bloood pressure in both normal and hypertensive individuals. One study, published in the European Journal of clinial Pharmacology in 1999, found that five cups of coffee a day over a period of about two months produced a modest increase in both systolic and diastolic blood pressure. Research has also shown that regular coffee drinkers may develop a tolerance to caffeine but that the elderly and people wih hypertansion might be more susceptible to caffeine's effects.
