Summary

McDonald's French Fries score 4/100. A seemingly simple fast food staple hiding one of the worst oil blends in the food industry. Potatoes fried in a quad oil blend: canola oil, corn oil, soybean oil, and hydrogenated soybean oil — three seed oils plus a partially hydrogenated oil containing trans fats. Dextrose (refined corn sugar) added for browning. Sodium acid pyrophosphate prevents graying. 'Natural beef flavor' is lab-derived from hydrolyzed wheat and milk — not actual beef. NOVA 4 ultra-processed. The clean fries equivalent (Jesse & Ben's: potatoes, grass-fed beef tallow, sea salt) scores 93/100. Owned by McDonald's Corporation.
