Rachel Frederickson's extreme weight loss on 'The Biggest Loser' led to health concerns and caused Jillian Michaels to quit the show, as she felt the contestant's unhealthily thin appearance was harmful and reflected poorly on the show's practices.
Seed oils, including canola and corn oil, have been criticized by wellness influencers and figures like Robert F. Kennedy Jr. for allegedly causing health issues like obesity and diabetes. However, nutrition scientists argue that these oils, rich in unsaturated fats, are healthier alternatives to saturated fats like butter and lard. Research indicates that omega-6 fatty acids in seed oils do not increase inflammation and are linked to lower risks of chronic diseases. Experts suggest reducing seed oil consumption by avoiding ultraprocessed foods rather than replacing them with saturated fats.
