The discovery that high levels of omega-3 and omega-6 fatty acids may help ward off a variety of cancers has been made by researchers. The study, led by Yuchen Zhang, a doctoral student at the University of Georgia's College of Public Health, analyzed data from more than 250,000 people. Of these, about 30,000 developed some form of cancer over a decade of follow-up.
Omega-3 and omega-6 fatty acids, often referred to as healthy fats, are essential for human health. They play a crucial role in cellular function, reducing bad cholesterol levels, maintaining brain health, and boosting mental health. The study found that higher levels of omega-3s showed protection against colon, stomach, and lung cancer.
On the other hand, high omega-6 levels were found to protect against brain, malignant melanoma, bladder, and 14 different cancers. Higher omega-3 and omega-6 levels were associated with lower rates of cancer, Zhang stated. This significant finding comes at a time when cancer rates are rising worldwide, emphasizing the need for preventative measures. Zhang suggests that the average person should focus on getting more of these fatty acids in their diets.
Omega-3 and omega-6 are present in fatty fish, nuts, and even some plant oils. However, as diets may not provide the recommended amounts, people often turn to fish oil supplements -- one of the most popular dietary pills on the market. However, it may not be suitable for all, said the researchers. The study showed that elevated omega-3 levels raised a slightly higher risk of prostate cancer in men. However, the study found no such associations in women. Instead, women and young people were found to have "stronger beneficial effects of omega-6".
This study's findings align with historical events where dietary changes have been linked to disease prevention. For instance, the Mediterranean diet, rich in omega-3 fatty acids, has been associated with lower rates of heart disease and certain cancers. Similarly, the traditional Japanese diet, high in fish and thus omega-3, has been linked to lower rates of heart disease and longer life expectancy.
However, it's important to note that while these findings are promising, they do not suggest that omega-3 and omega-6 supplements should replace a balanced diet or other cancer prevention strategies. It's also crucial to remember that while these fatty acids have been associated with lower cancer rates, they are not a cure for cancer. As with any dietary supplement, it's always best to consult with a healthcare professional before starting a new regimen.
