According to the American Institute for Cancer Research, evidence is growing which suggests that green tea may help prevent cancer. They are funding two researchers who are finding more valuable clues about how compounds in green tea actually work.
The natural substances in green tea are called polyphenols which seem to make it more difficult for a cancer cell to respond to their growth signals and this slows cancer growth.
One of the researchers is studying whether piperine (the substance that gives black pepper its heat) when taken with the green tea, will increase the amount of EGCG (a polyphenol) that gets into our blood and some tissues, compared to the polyphenol by itself. His findings indicated that it does.
Another researcher with the American Institute for Cancer Research is studying animal models and chronic liver disease to determine if EGCG hinders the development of liver cancer by inhibiting scarring which is called cirrhosis of the liver.
With this testing he tries to see if EGCG used alone and in combination with erlotinib (an experimental treatment for liver cancer) can slow tumor progression.
It is not yet known how much green tea a person would have to drink in order to be protected against cancer, but some studies indicate it would take 5-10 cups per day, while some epidemiological studies say you only need as few as 2 cups per day. There is still more data needed about that. One of these researchers are studying the need for 8-12 cups per day to see if that is the magic number. Either way, that is an awful lot of green tea to have to drink. This is why many supplement companies are offering a pill form of this important polyphenol in the type as EGCG or other polyphenol types as an antioxidant such as Resveratrol (found in red grape skin). Other forms of polyphenols are found in fruits, vegetables, tea, dark chocolate (70% cocoa or higher) and red wine.
Fruits are usually richer in polyphenols than vegetables, with citrus fruits and berries being the best fruit sources.
Certain polyphenols such as quercetin are found in all plant products, while others are only found in specific foods. Most foods contain quite a mix of different kinds of polyphenols.
It is hard to measure the exact polyphenol content of foods, and it is also likely that people will absorb them differently, and therefore two people might eat or drink the same amount but actually absorb different quantities. This is because the microbiota in your gut (which varies from person to person) is involved with the metabolism of polyphenols.
There are some interesting studies being done on animals using a combination of green tea and pharmaceutical medicines together to see if the outcome is best combined or alone. Definitely green tea is most likely to be promising when used with another treatment for early stage cancer or in post-chemotherapy treatment to prevent a recurrence.
Another important fact in helping to prevent or even treat cancer is in the way of avoiding ALL kinds of sugar. Sugars feed cancer cells, so by avoiding them, it helps to “starve” rather than “feed” the cancer. In Europe, the “sugar feeds cancer” concept is so well accepted that oncologists, or cancer doctors, use the Systemic Cancer Multistep Therapy (SCMT) protocol. Conceived by Manfred von Ardenne in Germany in 1965, SCMT entails injecting patients with glucose to increase blood-glucose concentrations. This lowers pH values in cancer tissues via lactic acid formation. In turn, this intensifies the thermal sensitivity of the malignant tumors and also induces rapid growth of the cancer. Patients are then given whole-body hyperthermia (42 C core temperature) to further stress the cancer cells, followed by chemotherapy or radiation.19 SCMT was tested on 103 patients with metastasized cancer or recurrent primary tumors in a clinical phase-I study at the Von Ardenne Institute of Applied Medical Research in Dresden, Germany. Five-year survival rates in SCMT-treated patients increased by 25 to 50 percent, and the complete rate of tumor regression increased by 30 to 50 percent. The protocol induces rapid growth of the cancer, then treats the tumor with toxic therapies for a dramatic improvement in outcome.
The role of glucose in the growth and metastasis of cancer cells can enhance many therapies. Some of these include diets designed with the glycemic index in mind to regulate increases in blood glucose, therefore selectively starving the cancer cells; low-glucose TPN solutions; taking avocado extract to inhibit glucose uptake in cancer cells; hydrazine sulfate to inhibit gluconeogenesis in cancer cells; and SCMT.
