The claim, are seed oils bad for you is not necessarily true. Studies have shown that labeling seed oils as harmful are misguided and avoiding ultra-processed foods and eating enough fruits and vegetables will have more health benefits than focusing on seed oils. According to Stanford Medicine, "For years, scientists have studied the difference between saturated fats that are solid at room temperature — think butter, lard and beef tallow — and unsaturated fats that are liquid at room temperature, including seed oils."
"Like many researchers before him, Gardner found that people who switched from using mostly saturated fat in their diets to eating more unsaturated fats saw their LDL cholesterol levels decrease. High levels of this type of cholesterol are associated with an increased risk of cardiovascular disease." This statement Dr. Gardner from Stanford Medicine claims how unsaturated fats in seed oils can lower cholesterol levels. Lower cholesterol levels can make a person healthier by reducing the risk of cardiovascular disease.

To support my claim, another source from Harvard Education states, “The idea that omega-6 fatty acids are pro-inflammatory is propagated over and over again in social media,” said Willett, professor of epidemiology and nutrition. “Dozens of studies have looked at this, and about half of them show no effect, while the other half show reduction in inflammatory factors.”
"Evidence suggests that foods containing omega-6 can help lower cholesterol and blood sugar and reduce heart disease risk." This argument claims that omega-6 fatty acids in seed oils do not cause inflammation, but actually reduce inflammation and lower cholesterol. https://hsph.harvard.edu/news/are-seed-oils-healthful-or-harmful/
In addition, an article from New York Gastroenterology Associates, express "One of the most common arguments against seed oils is that they may be inflammatory. However, this claim is based mainly on animal studies or outdated data. Most human clinical trials and epidemiological research do not support a direct link between moderate seed oil consumption and chronic inflammation."
"According to NYGA registered gastrointestinal dietitian Tamara Freuman, “Seed oils are actively helpful; people who eat seed oil have a higher intake of the Omega-6 that lowers cholesterol and can reduce the risk of all-cause mortality.”This claim directly supports the other claim from Harvard, supporting how seed oils do not cause inflammation. Seed oils can help lower cholesterol and reduce the risk of chronic disease. https://www.nygahealth.com/blog/the-truth-about-seed-oils-are-they-helping-or-harming-your-health/
To continue, evidence from John Hopkins Public Health, states, “The fatty acids typical in seed oils—like linoleic acid—are associated with lower risk of chronic diseases like cardiovascular disease, heart attack, strokes and diabetes.”
"These fats are broken down by the body and primarily used for energy. However, eating too much saturated fat—found in animal products and tropical oils like coconut and palm—can raise your cholesterol (LDL) and increase your risk of heart disease. Unsaturated fats, on the other hand, can have positive health effects when consumed in moderation as part of a balanced diet." This statement suggests how seed oils, once again can lower risk of chronic diseases and have positive heath benefits. This statement also suggests how a lot of saturated fat can be harmful towards the heart.

To conclude, an article from American Institution for Cancer Research stated facts from recent studies, including, "the body converts only a tiny fraction of omega-6 into compounds that can promote inflammation. Omega-6 fats also help make anti-inflammatory compounds. Diets higher in omega-6 fats are not associated with biomarkers of chronic inflammation. There is often lower chronic inflammation when diets are higher in omega-6 fats. Higher omega-6 levels are associated with lower risk of death from all causes, cardiovascular disease and cancer." This recent research and studies back all the other sources listed above, claiming how omega-6 fatty acids can actually reduce inflammation by making inflammatory compounds and are associated with a lower risk of death and disease.
