In addition, green tea extract has been linked to a lowering of the risk of some cancers. Countries wherever green tea extract is widely taken have significantly decrease incidences of chest cancer, lung cancer, prostate cancer and gastrointestinal cancers. In a few reports, green tea has also been proven to be a powerful adjunct treatment for many types of cancer.

Though both green and black tea come from the camellia sinensis plant, the amount and types of catechins found in green and dark tea differ for their various handling methods.When green tea extract is refined the leaves are instantly steamed following picking, that halts the oxidation of the leaves, meaning a higher concentration of catechins is kept in the leaves.

When dark tea is processed the leaves are first withered. The leaves are dry in the start air or air is motivated through the layers of leaves. The leaves are green tea catechins left to oxidise for an extended period and that causes the leaves to alter shade from green to coppery brown. Throughout this technique the catechins are changed into complex flavanoids called theaflavins and thearubigins.

There are four catechins in green tea. The catechins present in green tea extract are epicatechin (EC), gallocatechin (GC), epigallocatechin (EGC), epicatechin gallate (ECg) and epigallocatechin gallate (EGCg) The absolute most productive and useful catechin in green tea extract is epigallocatechin gallate (EGCG).Catechins function by neutralizing and inhibiting free radicals which destroy balanced cells and tissues in the body and contribute to aging and disease.

The catechins found in green and dark tea change due to their various processing methods. Green tea extract is definitely an unfermented tea (not subjected to oxygen following picking) and can keep their high catechin content. While dark tea is fully fermented (extensively oxidised), meaning much of the helpful catechin components are destroyed.

Even though both green and black tea contain catechins, green tea has the bigger catechin content of the two. To completely reap all the advantages of green tea extract, it is suggested you ought to drink between 3-10 cups a day. Personally, i suggest brewing your personal green tea extract leaves rather than using tea bags. The taste and quality of the leaves is superior and also you can re-brew with the same leaves once or twice over.
