For all you peanut allergic individuals, have you ever wondered about eating at restaurants that use peanut oil for cooking. Five Guys and Chick-fil-A are probably the two most well known examples. They use peanut oil in their fryers.
Cooking oils used by most restaurants, especially the big commercial franchises that use peanut oil, use a highly processed, refined peanut oil. Why is this important? The refining process involves high heat, deodorization, bleaching, purification, and other methods of processing to strip away the peanut proteins that are responsible for the allergic reaction to peanuts and leaves a purified, refined oil.
The peanut oils to avoid are often the gourmet peanut oils. These types of oils may have things like ‘cold-pressed,’ ‘natural,’ ‘unrefined,’ ‘gourmet’ or ‘aromatic’ on the labeling of the bottle. Found in the cooking oil aisles at supermarkets or specialty stores, these oils often forego the refining process and retain allergic proteins.
There are research studies that back up these findings, and the FDA makes specific note of oils in Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) [Paragraph 1-201.10(B)]. So, if you are craving those fries cooked in the peanut oil, chances are you can probably feel safe eating them. Now, the only reasons to avoid Five Guys might be the actual peanuts in their restaurants or your expanding waistline.
Always inquire about the oil before ordering, and discuss with your allergist if you have any questions or reservations.
