Coffee May Reduce Risk of
Lethal Prostate Cancer in Men
Men who regularly drink coffee appear to have a lower risk
of developing a lethal form of prostate cancer, according to
a new study led by Harvard School of Public Health (HSPH) researchers.
The study was published May 17, 2011, in an online edition
of the Journal of the National Cancer Institute.
"Few studies have specifically studied the association of coffee intake and the risk of lethal prostate cancer, the form of the disease that is the most critical to prevent. Our study is the
largest to date to examine whether coffee could lower the risk
of lethal prostate cancer," said the researchers.
Prostate cancer is the most frequently diagnosed form of
cancer and the second leading cause of cancer death among U.S. men, affecting one in six men during their lifetime. More
than 2 million men in the U.S. and 16 million men worldwide
are prostate cancer survivors. Lethal prostate cancer causes death or spreads to the bones.
"At present we lack an understanding of risk factors that can be changed or controlled to lower the risk of lethal prostate cancer.
If our findings are validated, coffee could represent one modifiable factor that may lower the risk of developing the
most harmful form of prostate cancer," they also explained.
The researchers chose to study coffee because it contains many beneficial compounds that act as antioxidants, reduce inflammation, and regulate insulin, all of which may influence prostate cancer. Coffee has been associated in prior studies with a lower risk of Parkinson's disease, type 2 diabetes, gallstone
disease, and liver cancer or cirrhosis.
The study examined the association between coffee consumption and the risk of prostate cancer, particularly the risk for aggressive prostate cancer among 47,911 U.S. men in the Health Professionals Follow-Up Study who reported their coffee consumption every four years from 1986 to 2008. During the study period, 5,035 cases of prostate cancer were reported, including 642 fatal or metastatic cases.
These Are The Major Findings:
Men who consumed the most coffee (six or more cups daily)
had nearly a 20% lower risk of developing any form of prostate cancer.
The inverse association with coffee was even stronger for aggressive prostate cancer. Men who drank the most coffee
had a 60% lower risk of developing lethal prostate cancer.
The reduction in risk was seen whether the men drank decaffeinated or regular coffee, and does not appear to be
due to caffeine.
Even drinking one to three cups of coffee per day was associated with a 30% lower risk of lethal prostate cancer.
Coffee drinkers were more likely to smoke and less likely to exercise, behaviors that may increase advanced prostate cancer risk. The other lifestyle factors were controlled for in the study and coffee still was associated with a lower risk.
The study was supported by the National Cancer Institute at the National Institutes of Health, the American Institute for Cancer Research, and the Prostate Cancer Foundation.

New Study Proves Cutting Down On Carbs Reduces Body Fat! A modest reduction in consumption of carbohydrate foods may promote loss of deep belly fat, even with little or no change in weight, an important new study reports. Results of the study are being presented at The Endocrine Society's 93rd Annual Meeting in Boston. When paired with weight loss, consumption of a moderately reduced carbohydrate diet can help achieve a reduction of total body fat, according to researchers from the department of nutrition sciences at the University of Alabama at Birmingham. "These changes could help reduce the risk of developing Type 2 diabetes, stroke and coronary artery disease," they said, noting that excess visceral, or intra-abdominal, fat raises the risk of these diseases. The researchers conducted the study, with funding from the National Institutes of Health, in 69 overweight but healthy men and women. Subjects received food for two consecutive eight-week periods: first a weight maintenance intervention, and then a weight loss intervention, which cut the number of calories that each person ate by 1,000 each day. Subjects received either a standard lower-fat diet or a diet with a modest reduction in carbohydrates, or "carbs," but slightly higher in fat than the standard diet. The moderately carb-restricted diet contained foods that had a relatively low glycemic index, a measure of the extent to which the food raises blood glucose levels. This diet consisted of 43 percent calories from carbohydrates and 39 percent calories from fat, whereas the standard diet contained 55 percent of calories from carbohydrates and 27 percent from fat. Protein made up the other 18 percent of each diet. At the beginning and end of each study phase, the researchers measured the subjects' fat deep inside the abdomen and their total body fat using computed tomography (CT) and dual-energy x-ray absorptiometry (DXA) scans. After the weight maintenance phase, subjects who consumed the moderately carb-restricted diet had 11 percent less deep abdominal fat than those who ate the standard diet. During the weight loss phase, subjects on both diets lost weight. However, the moderately carb-restricted diet promoted a 4 percent greater loss of total body fat, the researchers said. "For individuals willing to go on a http://www.blogger.com/img/blank.gifweight-loss diet, a modest reduction in carbohydrate-containing foods may help them preferentially lose fat, rather than lean tissue; The moderately reduced carbohydrate diet allows a variety of foods to meet personal preferences."

Obviously, oxygen will not be able to help you in the diet department. However, it can definitely help you be able to exercise harder and for longer periods of time, which should result in more calories burned.
