Wendy's discloses ingredients well and its beef patty statement is a single word, but 67 of 102 items contain a seed oil and 82 of 102 contain an additive, because every bun uses soybean or canola oil and the shared fryer runs soybean, canola, cottonseed and hydrogenated soybean oil with dimethylpolysiloxane. Chili, baked potatoes and the Frosty are the only genuinely seed-oil-free food.
Wendy's publishes full ingredient statements through order.wendys.com; 102 items had real data and 67 contain a named seed oil. The shared fryer is brutal: fries are "Cooked In Vegetable Oil (Soybean Oil, Vegetable Oil [May Contain One Or More Of The Following: Canola, Corn, Or Cottonseed], Hydrogenated Soybean Oil, Dimethylpolysiloxane [Anti-Foaming Agent])", and the same fryer covers all nuggets, tenders, seasoned potatoes and every fried chicken sandwich (26 items). The beef is genuinely clean, its statement literally reading "Hamburger Patty.", but every bun carries soybean and/or canola oil so no burger escapes. 82 of 102 items carry an additive: modified starch 52, mono-and-diglycerides 49, maltodextrin 32, HFCS 26, dimethylpolysiloxane 26, DATEM 21, polysorbate 17. Certified dyes appear in only 2 items, both Sparkling Energy drinks. Clean options exist but are marginal: chili, plain and sour-cream baked potatoes, and the Frosty.
