Introduction#
The relationship between omega-3 fatty acids and cancer has been a topic of interest in recent years, with some studies suggesting potential benefits and others raising concerns about their effects. As a result, it’s crucial to examine the current research and understand the complex relationships between nutrition and disease.
According to Liput et al. (2021), dietary recommendations encourage reducing saturated fatty acids (SFA) in diet and replacing them with polyunsaturated fatty acids (PUFAs) n-3 (omega-3) and n-6 (omega-6) to decrease the risk of metabolic disturbances [1]. This is supported by Al-Madhagy et al. (2023), who found that flaxseed oil, rich in omega-3 polyunsaturated fatty acids, may exert potential health benefits, including reduction of cardiovascular disease and cancer [3].
Mechanism of Action#
Omega-3 fatty acids have anti-inflammatory properties, which could potentially reduce cancer risk. As explained by Crauste et al. (2016), polyphenols and n-3 polyunsaturated fatty acids (PUFAs) have been highlighted in epidemiological studies for their health benefits, including their effects on oxidation, inflammation, cancer, cardiovascular, and degenerative diseases [8].
The biological activities of omega-3 fatty acids on cancer have been reported in vitro and in vivo. For example, Abel et al. (2014) found that dietary fat is an essential nutrient and important source for the essential fatty acids (FA), linoleic and α-linolenic acids, which contribute to proper growth and development [5]. However, dietary fat has also been associated with the development of colorectal, breast, prostate, endometrial, and ovarian cancers, with the type and quality of fat playing an underlying role.
Effects on Cancer Risk#
Several studies have investigated the effects of omega-3 fatty acids on cancer risk. Nkondjock et al. (2003) found that specific fatty acids, including omega-3 fatty acids, may play a role in the pathogenic process of colorectal cancer [7]. Similarly, Gerber (2012) suggested that observational studies on colorectal, prostate, and breast cancers only provide limited evidence for a possible role of LC-ω3PUFA in cancer prevention due to insufficient homogeneity of the data [11].
Breast Cancer Prevention and Survivorship#
Some studies have specifically examined the effects of omega-3 fatty acids on breast cancer prevention and survivorship. Fabian et al. (2015) found that supplementation with omega-3 fatty acids may have potential benefits for breast cancer prevention and survivorship, although more research is needed to confirm these findings [12].
Conclusion#
In conclusion, while some studies suggest potential benefits of omega-3 fatty acids in reducing cancer risk, the evidence is not yet conclusive. More research is needed to fully understand their effects and determine whether they can be used as a preventative measure or treatment for cancer.
It’s essential to consult with your healthcare provider before making any changes to your diet or supplement routine, especially if you have a history of cancer or are at high risk. By understanding the complex relationships between nutrition and disease, we can work towards developing effective prevention and treatment strategies for cancer.
