The green and black tea that we’ve been drinking for several hundreds of years come from the same plant, Camelia Sinensis. When dried, black tea is fermented and oxidised, whereas green tea is left unfermented. Many believe green tea is thus a better, more whole, source of natural polyphenols and anti-oxidants
Why are antioxidants and plant polyphenols important?
Polyphenols are natural plant based chemicals found in healthy foods which enhance our health and protect us from illnesses. Their antioxidant properties protect us from environmental and ingested chemicals which damage our DNA via a process called oxidation. Many studies have linked anti-oxidant rich foods with a lower risk of cancer and other chronic illnesses such as high cholesterol, dementia, arthritis, skin aging and macular degeneration (blindness). There are also some clinic studies which report that anti-oxidants in green tea may reduce the risk of cancer and reduce the relapse rate after radical treatments (see below).
Anti-cancer effect of tea
The most active polyphenol in green tea is thought to be epigallocatechin gallate (EGCG) which blocks an enzyme, ornithine decarboxylase, which tells cells to proliferate faster and bypass apoptosis [Yang 2002]. Green tea is also thought to block the effect of harmful estrogens which explains why a study in humans, regular tea drinkers demonstrated a 40% reduction in breast, prostate and ovarian cancer risk [Wu 2006, Ogunleye 2010].
A large combined analysis of several studies
encompassing 5,617 cases of breast cancer resulted in significant evidence to
support the hypothesis that regular green tea consumption may be inversely
associated with risk of breast cancer recurrence [Ogunleye 2010]. Research from
Shanghai showed a lower risk of oesophageal particularly benefit amoung smokers
and alcoholics [Sun 2007]. The Mayo Clinic researched green tea in
patients with chronic leukaemia and concluded that it helped decrease the
abnormal white cell count in 30% and those with enlarged lymph nodes had a 50%
reduction. A study from Louisiana University reported a significant
reduction in the levels of several growth factors that promote cancer as well as
a reduction in PSA amoung participants [Shanafelt TD et al 2009].
Other health benefits of green tea
As well as cancer, the polyphenols in green tea have also been shown to protect against heart disease, prevent the oxidation of LDL into cholesterol. Researchers from the University of Pennsylvania and Boston have also shown that EGCG helps protect the brain from the build up of amyloid proteins [Rezai-Zadeh K 2008]. They concluded that Green Tea would help prevent Parkinson´s and Alzheimer’s, and could also be used in treatment. Researches from the American College of Nutrition found that regular consumption may also prevent colds and flu. Green tea is also alleged to improve skin tone, smooth out wrinkles and even to help you slim. EGCG is also known to help good bacteria in the intestine to flourish, aiding recovery after antibiotics or chemotherapy [Maclarty 2009].

Millions of people enjoy tea on a daily bases with no adverse effects. Green tea can cause discolouration of the teeth - this should not be a problem with unless Pomi-T is chewed. In very high doses, patients who took 6 kg/day, experienced mild to moderate nausea, vomiting, abdominal pain, diarrohea, agitation, restlessness, insomnia, tremors, dizziness, and confusion[Jatoi A et al 2003, Pisters KM et al 2001]. The safety of tea extracts for pregnant or breast feeding women has not been established.
Green tea extract
tea can be pleasant and comforting but taking a supplement ensures a higher daily
dose and not everyone likes the taste of green tea. There are many green tea extracts are available on the open market
but it would be advisable to take a tablet which has been combined with other
anti-oxidant rich foods.

whilst at the same time avoiding over-consumption of one particular type.

sponsored by the charity Prostate Action, has been adopted by the National
Cancer Research Network (NCRN), has UK Ethics Committee certification and is
independently audited to ensure adherence to European Good Clinical Practice
Guidelines (GCP). The chief investigator Professor Robert Thomas is Chair of

the world’s largest RCT of a food supplement to date and the full results will
be available in early 2013.
