Green Tea Can Prevent Heart Attack, Study Claims

Green tea is no less than a wonder! You want to lose weight with minimum side effects? Green tea is here. You want to perform smart at work? Green tea is here. You want to treat that elevated sugar in your blood. Green tea is here. Moreover, green tea also reduces the risks of Alzheimer’s and Parkinson’s disease during old age. Lately, it has been reported to fight cancer potentially.

Another important benefit of green tea has been reported which makes the drink even more striking and worth a try.

The scientists have discovered that a constituent of green tea is potent enough to dissolve the protein plaques in the veins and arteries that may promote situations like a cardiac failure and heart attacks.

Epigallocatechin-3-gallate (EGCG) is the respective compound in the discussion. It is recognized to reduce amyloid plaques in the brain that may cause Alzheimer’s disease. In addition, it has a similar effect on blood vessels, where the compound is reported to reduce the risks of cardiovascular diseases.

Over-consumption of fatty meals leads to the thickening of the blood vessels. It reduces the blood flow to the vital organs like heart and brain. A protein called “apoA-1” also promotes the deposition of fats under the lining of vessels which further increases the risk of heart attacks and strokes.

In this study, researchers from the University of Leeds and Lancaster University reported EGCG to combine with amyloid fibers present in apoA-1. This combination causes them to be converted into smaller and soluble molecules. These molecules being soluble in nature are then reported to cause fewer hazards and damages to blood vessels.

The massive quantity of green tea is also harmful to the body. Consequently, it should not be the last hope of obtaining EGCG. Thus, the researchers are trying to access some alternative, effective, and natural sources of acquiring EGCG. They are considering injecting EGCG directly into the body so that it can target the plaques more quickly and effectively. They are struggling to devise ways that may render EGCG more soluble and easily absorbable by the body cells.

The co-author of the study, Professor Sheena Radford, stated that the results of this experiment are very encouraging for the application of scientific techniques in order to extract the molecular EGCG element from green tea and employ it as a functioning tool to prevent life-limiting health issues.

Green tea is basically brewed from the dried leaves of the Camellia sinensis plant. Unlike other teas, green tea is not fermented. It is a product of pan frying or steaming of Camellia sinensis leaves which are then cool down or dried out to prevent oxidation. This imparts a characteristic green appearance and an unoxidized taste to the drink.

In addition to EGCG, green tea also contains a high amount of polyphenols and metallic minerals like manganese, selenium, chromium, and zinc. It also contains vitamin A, C, D, and E. The polyphenols have a tumor-reducing effect. Thus, regular consumption of green tea has been reported to lower the risk of skin, colon, prostate and breast cancers. Other constituents reduce the harmful effects of free radicals inside the body.

Green tea comes in different varieties. Matcha, Shincha, Hojicha, and Gyokuro are few of them. Matcha is reported to possess ten times more antioxidants than regular green tea. It’s a powder form of green tea leaves that have been placed in a shade for several weeks before harvesting. It also has a higher level of chlorophyll content which carries out the essential detoxification inside the body. It also possesses L-theanine to improve mental alertness. The level of EGCG is also significantly high in Matcha.

Green tea is loaded with healthful constituents. Its consumption within beneficial ranges offers plentiful advantages to the consumer.
