Flaxseed Lignans and Soy Foods slash the risk of prostate cancer in this Scottish study
Scottish men between the ages of 50 to 74 had their blood tested and filled out food frequency questionnaires to determine their phytoestrogen intake. The Lignan created out of Flaxseed lignans known as enterolactone significantly impacted health and decreased the risk of prostate cancer by 60% and soy foods decreased the risk by 48%. The study is published in the August 2007 issue of the British Journal of Nutrition.
Green Tea slashes the risk of deadly oral cancer in Japanese women
In a study of almost 50000 Japanese individuals followed for 10.3 years on average, scientists report that women who consumed 5 or more cups of Green Tea a day had a 70% reduced risk of developing oral cancer compared to women who had 1 to 2 cups a day; this is cancer of the lip or mouth or back of throat. Oral cancer has a higher proportion of deaths than breast, skin, or cervical cancer in women partially at least because it is detected at a more advanced stage and this death rate is about 50%. The study is published in the June 20th, 2007 issue of Annals of Epidemiology.
Commentary by Jerry Hickey, R.Ph.; The advantage wasn't the same for men but Japanese men have one of the highest incidences of smoking on the planet and this habit would likely negate the antioxidant effects of Green Tea in the mouth where tobacco carcinogens are formed and inflammation causing smoke is in direct contact with the tissue repeatedly throughout the day. The intake of alcohol which also triggers inflammation in the mouth and would negate the effects of Green Tea, is also higher in Japanese males.
Folic Acid from food and especially from supplements decreases the incidence of invasive breast cancer
Swedish researchers from Lund University are the most current group to connect low levels of the important B-complex vitamin Folic Acid with a jump in breast cancer risk. The study included 11699 women 50 years-of-age or older who were followed for 9.5 years on average. The women in the top 20% of Folic Acid intake had a 44% drop in the risk of developing invasive breast cancer versus those in the bottom 20% of Folic Acid intake. Supplements of Folic Acid decreased the risk by 44% and food sources decreased the risk by 41%. The study is published in the August 2007 issue of the American Journal of Clinical Nutrition.
