Omega-3 fatty acids from fish oil can help fight prostate cancer on various levels, according to recent research. Despite not being the first study to present a positive correlation between fish oil and the reduction of prostate cancer growth and progression, this study does emphasize the potential of fish oil in modifying the clinical course of prostate cancer through the immune system.
Immunotherapy, which involves utilizing the immune system to repair, enhance, or stimulate the body’s natural immune responses to combat cancer, has become a rapidly growing field of research. As scientists work to address the challenge of prostate cancer, they have developed or are in the process of developing different immunotherapeutic approaches. Natural substances, such as omega-3 fatty acids, may also hold potential in this field.
How Can Omega-3 Fatty Acids Combat Prostate Cancer?
A study conducted by the University of California investigated the hypothesis that a fish oil-based diet could inhibit the infiltration of immune system cells called tumor-associated macrophages, which play a significant role in the development of prostate cancer. The researchers tested their hypothesis using mice in which prostate cancer tumors were grown. They fed half of the mice a diet high in omega-3 fatty acids (fish oil), while the other half received omega-6 fatty acids (corn oil).
The tumor volumes were substantially smaller in the mice fed the fish oil diet. These mice also had lower levels of factors associated with cancer growth and progression, including markers for M1 and M2 macrophages, tumor necrosis factor-alpha, interleukin-6, interleukin-10, and the chemokine CCL-2. The results of in vitro experiments conducted by the research team were similar to these findings.
Although more research is needed to better understand the role of fish oil in inhibiting factors involved in prostate cancer, now may be the ideal time to incorporate more omega-3 fatty acids into your diet.
Benefits of Omega-3
Previous research has shown a lower risk of prostate cancer associated with a higher intake of omega-3 fatty acids from fish oil. Good dietary sources of omega-3 fatty acids include wild salmon, tuna, herring, sardines, and mackerel, as well as high-quality fish oil supplements.
It is important to choose fish and supplements from uncontaminated sources. For those who don’t consume fish two to three times a week, omega-3 supplements made from clean sources and without unnecessary additives should be considered.
This study and its findings shine a light on the potential benefits of including fish oil and omega-3 fatty acids in the fight against prostate cancer. Of course, one should consult with a healthcare professional before making any significant changes to their diet or supplement regimen. Additionally, a balanced and varied diet containing a variety of nutrients is essential for overall health and well-being.
Omega-3 fatty acids have been linked to numerous health benefits beyond prostate cancer prevention, including improved heart health, brain function, joint health, and even mood regulation. By incorporating omega-3 rich foods or supplements into your diet, you could not only be taking a step towards reducing your risk of prostate cancer but also improve your overall health and quality of life.
