Are seed oils bad for you?
Seed oils such as canola, soybean, sunflower, cottonseed, corn, grapeseed, rice bran, and safflower are commonly used in cooking. Despite some claims that these oils may be harmful and lead to health issues, recent research suggests otherwise.
Many people believe that the high levels of omega-6 fatty acids in seed oils can lead to increased inflammation in the body, which is associated with various health conditions. However, recent studies have found that consuming linoleic acid, a common omega-6 fatty acid found in seed oils, does not necessarily lead to inflammation.
In fact, some studies have shown that higher levels of linoleic acid are linked to a reduced risk of cardiovascular disease and metabolic diseases like type 2 diabetes. Additionally, research has found that consuming linoleic acid does not increase inflammation in the body.
While it is true that most people consume more omega-6 than omega-3 fatty acids, the ratio between the two does not seem to have a significant impact on inflammation levels. Studies have shown that as long as a person is consuming an adequate amount of omega-3 fatty acids, the ratio between omega-6 and omega-3 is not a cause for concern.
Overall, research suggests that consuming seed oils, which contain omega-6 fatty acids, is not necessarily harmful and may even have some health benefits. Studies have found positive associations between consuming omega-6 fatty acids and improved health outcomes, contradicting previous beliefs about the potential negative effects of these oils. After following the subjects for an average of 22.4 years, researchers discovered that higher levels of linoleic acid in the blood were associated with a reduced risk of death from cardiovascular disease and overall mortality. Similar positive associations were found with arachidonic acid, although they were not as strong.
A separate study that analyzed data from 30 different studies involving nearly 70,000 participants from 13 countries found that increased levels of linoleic acid were linked to a lower risk of cardiovascular disease, death from cardiovascular disease, and a specific type of stroke. Interestingly, higher levels of arachidonic acid were not associated with an elevated risk of cardiovascular disease; in fact, individuals with the highest levels had a decreased risk.
Furthermore, a large study involving over 120,000 individuals focused on type 2 diabetes and concluded that higher linoleic acid intake was associated with a lower risk of developing the condition.
Dr. Sarah Berry, ZOE's chief scientist and an associate professor at King's College London, emphasized that consuming omega-6 fatty acids is safe as long as an adequate amount of omega-3 is also included in the diet. She explained that current evidence does not support concerns about omega-6 causing inflammation and that it may actually have a protective effect against various chronic diseases.
Regarding concerns about seed oils containing harmful substances such as trans fats, synthetic antioxidants, and peroxides, it was clarified that strict quality checks in the UK and US ensure the safety of these oils. Any potentially harmful chemicals are removed during processing, and industrial seed oils no longer contain significant amounts of trans fats. The claim that seed oils contribute to chronic diseases like obesity and diabetes was debunked, with emphasis on the importance of distinguishing between correlation and causation when interpreting data.
In conclusion, while individuals have the option to avoid seed oils if they prefer, the existing evidence suggests that they are safe for consumption. Switching to olive oil as an alternative is recommended if one chooses to avoid seed oils. Conspiracy theories surrounding the purported dangers of seed oils were dismissed as unfounded, with the suggestion that those promoting seed oil-free products may have ulterior motives for profit. following sentence in a more concise way:
