Fish Oil May Increase Prostate Cancer Risk



A new study suggests that high levels of fish oil in the blood may increase prostate cancer risk.


 

FISH OIL MAY INCREASE PROSTATE CANCER RISK

As I discuss in my book, A Cancer Prevention Guide for the Human Race, there is research evidence available suggesting that omega-3 fatty acids, which are abundant in fatty fishes and fish oil supplements, may potentially decrease the risk of breast cancer and other types of cancer.  Indeed, in a recent column I reviewed a new study that strongly suggested a role for fish oil supplements in the prevention of breast cancer (Fish Oil May Decrease Breast Cancer Risk).  Now, a newly published clinical research study suggests that fish oil may increase the risk of prostate cancer, and aggressive forms of prostate cancer in particular.  This newly published study appears in the current issue of the Journal of the National Cancer Institute.

In this study, 834 men diagnosed with prostate cancer were compared with 1,393 age-matched men without prostate cancer. All of these men underwent measurement of the levels of fish oil-derived omega-3 fatty acids (EPA, DPA and DHA) in their blood.  After measuring and comparing the levels of fish-derived omega-3 fatty acids in the blood of these research volunteers, the researchers found that the volunteers with the highest levels of these omega-3 fatty acids were 44 percent more likely to be diagnosed with favorable forms of prostate cancer, and 71 percent more likely to be diagnosed with more aggressive forms of prostate cancer, when compared to the men with the lowest levels of fish-derived omega-3 fatty acids in their blood. Overall, men with the highest levels of fish-derived omega-3 fatty acids in their blood were 43 percent more likely to be diagnosed with any form of prostate cancer when compared to men with the lowest levels of fish oil-derived omega-3 fatty acids in their blood.  On the other hand, men with the highest blood levels of fatty acids derived from plants (omega-6 fatty acids) actually had a 23 percent lower likelihood of developing any form of prostate cancer.

As I have pointed out often before, studies such as this one can point out potential associations between specific lifestyle habits and the risk of cancer (or other diseases).  However, they cannot truly prove a “cause-and-effect” relationship between individual lifestyle factors and disease risk.  To arrive at this higher level of proof, a large prospective, randomized, placebo-controlled, blinded clinical research trial is necessary.  However, given that this is not the first research study to link high levels of fish-derived omega-3 fatty acids with an increase in prostate cancer risk, I have recently cut back on my own intake of both fish and fish oil supplements.  (Like millions of other people who take fish oil supplements and who regularly eat fish, I long ago added these items to my diet in the hope that I would significantly reduce my risk of cardiovascular disease.  However, a recent prospective, randomized, placebo-controlled clinical study of fish oil supplements in patients at elevated risk for cardiovascular disease showed no apparent reduction in the risk of heart attacks or strokes, or other cardiovascular disease events, among the research volunteers who were randomized to receive fish oil supplements.)

Until a large-scale prospective, randomized, blinded, placebo-controlled study is performed to validate the findings of this “case-cohort” public health study, it would seem prudent to cut back on daily fish oil supplements, which I myself have done.

Fish Oil May Lower Breast Cancer Risk



A new study suggests that fish oil supplements rich in omega-3 fatty acids may significantly lower breast cancer risk.


 

 

FISH OIL MAY LOWER BREAST CANCER RISK

As I discuss in my book, A Cancer Prevention Guide for the Human Race, there is research evidence available suggesting that omega-3 fatty acids, which are abundant in fatty fishes and fish oil supplements, may potentially decrease the risk of breast cancer and other types of cancer. Now, a newly published research study, a meta-analysis, further suggests that omega-3 fatty acids from fish oil may decrease breast cancer risk. This new study appears in the current issue of the British Medical Journal.

In this meta-analysis study, 21 previously published prospective clinical research studies were analyzed. Together, these 21 clinical studies included 883,585 participants and 20,905 breast cancer cases.

Based upon the findings of this meta-analysis, both increased fish oil intake (as a dietary supplement) and high blood levels of fish oil-derived omega-3 fatty acids were associated with an identical 14 percent lower incidence of breast cancer.(Interestingly, there did not appear to be any protective effects against breast cancer associated with omega-3 fatty acids derived from plant sources.)

Meta-analysis is commonly used to combine multiple small individual studies, thereby increasing the power of their scientific findings. In the case of this particular meta-analysis, the hypothesis being studied is the association, if any, between omega-3 fatty acids and breast cancer risk. In the case of fish oil supplement consumption, and increased blood levels of omega-3 fatty acids derived from fish oil, this meta-analysis strongly suggests that fish oil supplements may significantly reduce breast cancer risk

Fish Oil Improves Memory, Reduces Diabetes and Heart Disease Risk Factors



Fish Oil Improves Memory, Reduces Diabetes and Heart Disease Risk Factors


 

 

 

FISH OIL IMPROVES MEMORY, REDUCES DIABETES AND HEART DISEASE RISK FACTORS

Fish oil, which is rich in anti-inflammatory omega-3 polyunsaturated fatty acids, can play an important role in maintaining cardiovascular health.  There is also research data available to suggest that regular supplements of fish oil may improve brain function, including memory, in older patients.  Now, a recently published research paper, which appears in the Nutrition Journal, provides strong evidence that fish oil supplements can indeed improve cognitive function, while simultaneously reducing risk factors for cardiovascular disease.

In this study, 40 healthy middle-aged and elderly research volunteers underwent initial evaluation, including blood tests and cognitive function testing.  In this “placebo-controlled crossover” study, the volunteers were randomly divided into two groups.  One group received 3 grams of fish oil per day, while the other group received a placebo (sugar) pill.  After 5 weeks, the two groups of research volunteers were retested, and were then switched, or “crossed over,” with respect to the fish oil supplements and placebo pills.  After 5 additional weeks, the research volunteers were all once again retested.

Retesting of these research volunteers showed a significant improvement in memory function after taking fish oil for 5 weeks (when compared to the volunteers who were taking placebo pills).  Moreover, fish oil supplementation was also associated with a lower level of fat (triglycerides) in the blood, lower blood pressure, lower blood sugar levels, and a decrease in the level of the inflammatory protein TNF-alpha (tumor necrosis factor-alpha).

Taken together, the findings of this clinical study identified several apparent health benefits associated with daily fish oil supplements in middle-aged and elderly research volunteers, including improved memory function and improvements in multiple known risk factors for cardiovascular disease and diabetes.
