Green Tea ‘May Block Lung Cancer’

Drinking green tea may offer some protection against lung cancer, say experts who studied the disease at a medical university in Taiwan.

The latest work in more than 500 people adds to growing evidence suggesting the beverage has anti-cancer powers.

In the study, smokers and non-smokers who drank at least a cup a day cut their lung cancer risk significantly, a US cancer research conference heard.

The protection was greatest for people carrying certain genes.

But cancer experts said the findings did not change the fact that smoking is bad for health.

Daily cuppa:-

Green tea is made from the dried leaves of the Asian plant Camellia sinesis and is drunk widely across Asia.

The rates of many cancers are much lower in Asia than other parts of the world, which has led some to link the two.

Laboratory studies have shown that extracts from green tea, called polyphenols, can stop cancer cells from growing.

But results from human studies have been mixed. Some have shown a protective effect while others have failed to find any evidence of protection.

In July 2009, the Oxford-based research group Cochrane published a review of 51 studies on green tea and cancer which included over 1.5 million people.

They concluded that while green tea is safe to drink in moderation, the research so far is conflicting about whether or not it can prevent certain cancers.

Reduced risk:-

Dr I-Hsin Lin, of Shan Medical University, found that among smokers and non-smokers, people who did not drink green tea were more than five times as likely to get lung cancer than those who drank at least one cup of green tea a day.

Among smokers, those who did not drink green tea at all were more than 12 times as likely to develop lung cancer than those who drank at least a cup a day.

Researchers then analysed the DNA of people in the study and found certain genes appeared to play a role in the risk reduction.

Green tea drinkers, whether smokers or non smokers, with certain types of a gene called IGF1, were far less likely to develop lung cancer than other green tea drinkers with different types of this gene.

Yinka Ebo, of Cancer Research UK, said the findings should not be used as an excuse to keep smoking.

“Smoking tobacco fills your lungs with around 80 cancer-causing chemicals. Drinking green tea is not going to compensate for that.

“Unfortunately, it’s not possible to make up for the harm caused by smoking by doing other things right like eating a healthy, balanced diet.

“The best thing a smoker can do to reduce their risk of lung cancer, and more than a dozen other cancer types, is to quit.”

Green Tea Extracts May Protect You From Oral Cancer

Extracts from green tea may prevent the formation of mouth cancers in people with risk signs of the disease, according to a new study from Texas. Over 50 percent of participants in the University of Texas M. D. Anderson Cancer Center study experienced a clinical response to the green tea extracts.

Said lead researcher Vassiliki Papadimitrakopoulou, MD.:…

“While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer.

The extract’s lack of toxicity is attractive — in prevention trials, it’s very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm. We need to further understand if green tea offers longer-term prevention effects for patients.”

Almost 60 percent of people taking the two highest doses of the green tea extracts had a clinical response.Just over 36 percent of people in the lowest extract dose group had a clinical response, compared to 18 percent in the placebo group, said the researchers.

Green Tea May Help Reduce Risk of Certain Cancers

[amazon_link asins=’B00DE4NPV0,B003D4F2US,B01G0S3Y44,B0042IMPTU,B000GG0BNE,B00PFDH0IC,B000WB1YSE,B0016BFR4G,B0017T2MWW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ebebe9be-5c8d-11e7-ae93-dd4a39e89aff’]

Researchers in Japan have said drinking green tea may be an important health resource to reduce the risk of developing certain types of cancer.

The study appearing in the American Journal of Epidemiology suggests drinking five or more cups of the antioxidant-rich beverage can reduce the risk of developing blood cancer by 42 percent. The same amount of green tea was also associated with a 48 percent lower risk of lymph system cancer, according to Reuters.

Researchers followed 19,749 men and 22,012 women with no previous history of cancer over a period of nine years for the study.

WebMD notes that previous research has linked the tea to fighting heart disease, lowering cholesterol and preventing diabetes and dementia.

“Taken altogether, the evidence certainly suggests that incorporating at least a few cups of green tea every day will positively affect your health. It’s not going to cure anything and it shouldn’t be consumed as a drug, but it can complement the rest of the diet,” Tufts University scientist Dr. Diane McKay tells WebMD.

Researchers involved with this study say further work is needed to confirm the health benefits of drinking green tea, and to determine whether daily consumption might prevent certain cancers.

The Devil in the Milk

Prominent food researcher Dr. Thomas Cowan has been involved in thinking about the medicinal aspects of cow’s milk virtually his entire career.
.PASTEURISED  MILK..……….RAW MILK
His studies on the subject started in earnest when he read the book The Milk of Human Kindness Is Not Pasteurized, by maverick physician, William Campbell Douglass, MD.
Cowan became convinced that a large part of the disease in this country is related to the way we handle, or rather mishandle, milk and milk products.

Raw and cultured dairy products from healthy grass-fed cows are one of the healthiest foods people have ever eaten. However, pasteurized milk products have caused more disease than perhaps any other substance people are generally in contact with….…...CLICK & SEE

However, he still felt that a piece of the puzzle was missing. Many of his patients, in spite of eating only the proper dairy products, still had illness and still seemed not to tolerate milk. Recently, he was asked to consider writing the foreword to a book called The Devil in the Milk, written by Dr. Keith Woodford, which was again an eye-opener for him.

All proteins are long chains of amino acids. Beta casein is a chain 229 amino acids in length. Cows who produce this protein in their milk with a proline at number 67 are called A2 cows, and are the older breeds of cows (e.g. Jerseys, Asian and African cows). But some 5,000 years ago, a mutation occurred in this proline amino acid, converting it to histidine. Cows that have this mutated beta casein are called A1 cows, and include breeds like Holstein.

Proline has a strong bond to a small protein called BCM 7, which helps keep it from getting into the milk, so that essentially no BCM 7 is found in the urine, blood or GI tract of old-fashioned A2 cows. On the other hand, histidine, the mutated protein, only weakly holds on to BCM 7, so it is liberated in the GI tract of animals and humans who drink A1 cow milk.

BCM 7 has been shown to cause neurological impairment in animals and people exposed to it, especially autistic and schizophrenic changes. BCM 7 interferes with the immune response, and injecting BCM 7 in animal models has been shown to provoke type 1 diabetes. Dr. Woodford’s book presents research showing a direct correlation between a population’s exposure to A1 cow’s milk and incidence of autoimmune disease, heart disease, type 1 diabetes, autism, and schizophrenia.

Simply switching breeds of cows could result in amazing health benefits.

Green Tea Reduce Stroke Risk

[amazon_link asins=’B0016BFR4G,B0042IMPTU,B00DE4NPV0,B01G0S3Y44,B003D4F2US,B000WB1YSE,B00PFDH0IC,B000GG0BNE,B0017T2MWW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’3fd1733a-46dc-11e7-9d8e-a527a21f8cb4′]Two cups of green tea a day may reduce a person’s risk of having the most common form of stroke, say researchers.
According to researcher Professor Colin Binns, of the School of Public Health at Curtin University in Western Australia, the study shows that people who drink at least one cup of green tea a day reduce their risk of ischemic stroke, reports ABC Online.

“We can say if you are going to drink a beverage, then tea is the healthier option,” said Binns. “We believe other kinds of tea are half as effective as green tea in reducing risk,” he added. The findings have been published in the journal Stroke.
