Over the years, researchers have stipulated that green or black tea consumption reduces the chance of heart problems. This is essential because people from all walks of life inevitably suffer from some form of this potentially deadly disease. Based on the American Heart Association, in 2003, there were 71, 300, 000 people that have this disease plus it claimed 910, 614 lives that year alone. This disease does not just affect people in the usa. It also affects international residents. In the U. K alone, heart problems was accountable for over 23, 000 deaths in 2004. Put simply, every one (no matter where they live) reaches risk with this potentially deadly disease. With this thought, researchers have been working diligently to combat this illness. Numerous epidemiologic studies have indicated that consumption of green or black tea reduces the chance of heart problems. However, the majority are left wondering? How??. Scientists have made many assumptions about how these eas positively affects heart problems and research is still pending. One hypothesis states that drinking green or black tea affects lipoproteins. However, researchers have found that drinking green or black tea does not boost the resistance of low-density lipoprotein to oxidation in humans or the serum lipid concentrations in humans either. Researchers determined this within a four week long parallel study comprising of 45 volunteers. The study involved the subjects drinking 900 ml (6 cups) of reverse osmosis water filtration, black tea, or green tea daily. Blood samples were dutifully collected from the fasting subjects, both before and following the study. An in vitro experiment was carried out to record the result of adding tea extract to plasma and the consequence on the resistance of isolated LDL to oxidation. Data was carefully evaluated utilizing various research methodologies and researchers concluded that the said 900 ml (6 cups) of the beverage did have no substantial impact on either serum lipid concentrations or resistance of LDL to oxidation. However, It was determined that the large intake of green tea did boost the total antioxidant activity of the plasma slightly. Nevertheless, the arresting effect of tea flavonoids on heart problems can be an open proposition and researchers remain evaluating other probable mechanisms. For example, many researchers stipulate that green or black tea might have a positive impact on the panacea and on heart problems. Before we discuss this hypothesis further, let? s take the time to go over how heart problems is triggered. Sometimes, heart problems runs in families, and in other cases it doesn? t. Many of its victims experience such triggers like high cholesterol, raised blood pressure, and obesity. Furthermore, stress is thought to contribute to this disease. As a result, physicians currently prescribe a preventive diet of fruits, vegetables, nuts, and Omega 3 fatty acids to keep this disease away. Furthermore, physicians also suggest that patients take part in regular exercise, reduce panic and anxiety levels, and give up smoking to help prevent and keep CVD in balance. Furthermore, drinking black or green tea can be an essential addition on the list. However, it is still unclear the extent to which tea helps get a grip on CVD, but researchers are not stopping. Animal and in vitro studies have suggested numerous and probable cardiovascular protective mechanisms of tea which include prohibition of oxidized LDL cholesterol, the disintegration of the inflammatory process in atherosclerosis, reducing thrombosis, promotion of normal endothelial function, reduction of total plasma, and LDL cholesterol and adhesion molecules blocking mechanisms. Furthermore, the result of tea consumption on platelet aggression shows mixed results. A study by Duffy, et al. noted a better endothelial function post consumption of black tea. Furthermore, researchers think that green or black tea also positively effect endothelial function and also have found that polyphenolic compounds in tea other than catechins have the effect of improved endothelial function in humans. Blood pressure is another area where the cardio-protective properties of tea are believed to have a positive influence. However, studies have shown that the positive effect sometimes appears among subjects who had been drinking tea for at least annually, if not more. Short-term tea drinking have not made a lot of a big change.
