Omega-3 Fatty Acids May Increase Inflammation and Chronic Disease Risk, Study Finds
A study conducted by Australian researchers suggests that omega-3 fatty acids, long considered beneficial for heart health, may actually increase inflammation and the risk of chronic diseases such as obesity, type 2 diabetes, and heart attacks. The study highlights the importance of balancing omega-3 and omega-6 fatty acids in the diet.
🐟🩺💔🥑🧪A new study led by Professor Daisy Crick, a molecular science expert at the University of Queensland, challenges the long-held belief that omega-3 fatty acids are universally beneficial for health. The research indicates that omega-3s, found in fatty fish, nuts, and avocados, may trigger inflammation in the body and increase the risk of obesity, type 2 diabetes, and heart attacks.
The study found that omega-3s can raise levels of GlycA, a biomarker associated with inflammation. This discovery contradicts the traditional view that omega-3s are anti-inflammatory while omega-6s are pro-inflammatory.
Professor Crick stated, “Simply increasing omega-3 intake may not be enough to reduce inflammation or protect against heart disease. Focusing on the balance between these fats is crucial for healthier outcomes.”
Professor Thomas Holland from the RUSH Institute for Healthy Aging in Chicago described the findings as “unexpected.” He said, “Most people think omega-3s calm the immune system. However, this study linked higher omega-3 levels to more inflammation.”
Seed Oils May Also Pose Risks
The research also highlighted the potential risks of seed oils, such as sunflower, soybean, and rapeseed oil, which have long been promoted as heart-healthy alternatives. The study suggests that these oils may be linked to obesity, heart disease, diabetes, and autoimmune disorders.
Professor Holland noted, “In the UK, around 6.3 million people live with high cholesterol, which can significantly increase the risk of heart attacks and strokes if left untreated. We shouldn’t overlook the possibility that seed oils may be contributing to this issue.”
Rising Heart Disease Rates
According to data from the UK National Health Service (NHS), while heart disease-related deaths in people under 75 have declined since the 1960s, rising risk factors such as obesity and hypertension are leading to an increase in heart attacks and strokes.
Experts emphasize that the rise in heart disease cases, particularly among younger individuals, is not only linked to lifestyle factors but also to certain entrenched beliefs about nutrition that need to be reevaluated.
The study, published in the International Journal of Epidemiology, calls for further research to better understand the long-term health effects of fatty acids.
