Why do people like RFK Jr. think seed oils are unhealthy? What are they?
They are known to their numerous outspoken critics as “the hateful eight.” Refined oils derived from the seeds of specific plants, such as canola, corn, and sunflower oils, have become popular among politicians and wellness gurus. They are “unknowingly poisoning” Americans, according to Robert F. Kennedy Jr. Influencers, blogs, and online forums claim that they are “toxic,” “slowly killing you,” and increasing the prevalence of chronic conditions like diabetes and obesity. Nutrition scientists, who view seed oils as a significant improvement over butter and lard, find the notion that they are destroying human health particularly offensive. Consuming seed oils has been linked to improved health for decades, according to Stanford University medical professor Christopher Gardner. He continued by saying that to imply contrary “just undermines the science.” We sought experts to help us understand the ambiguity surrounding the effects of these oils on our bodies. Seed oils: what are they? Refined plant-based vegetable oils are now commonly referred to as seed oils. The “hateful eight” oils, which also include rice bran, cottonseed, soybean, safflower, and grapeseed oils, are not all technically derived from seeds. For instance, a bean is used to make soybean oil. Additionally, some seed oils are not included in that list, such as flaxseed and sesame oils. Unsaturated fats make up the majority of these oils. The majority of them had low levels of omega-3 fatty acids and high levels of omega-6 fatty acids. According to Eric Decker, a food science professor at the University of Massachusetts Amherst, seed oils are created by pressing the seeds to extract the oils. Stopping there results in a cold-pressed oil, similar to extra-virgin olive oil, which is high in healthy plant-based chemicals but is susceptible to smoke and deterioration when heated to high temperatures. According to Decker, manufacturers typically use heat and solvents to further process the oils in order to extract more oil from the seeds. Additionally, they frequently eliminate some of the ingredients that can cause splattering, rancidity, disagreeable flavours, or a dark hue. According to Decker, these procedures provide an oil with a neutral flavour that is reasonably shelf stable and suitable for usage at high temperatures without readily smoking. […]
