Cold-pressed or gourmet peanut oil (like in some Asian cuisines) is NOT safe —it contains peanut proteins. What the FDA Says: "Most individuals with peanut allergy can safely eat highly refined peanut oil, but should avoid cold-pressed or unrefined oils." Should you risk it? If your allergy is mild , you might tolerate refined peanut oil. If your allergy is severe , avoid all peanut oil —better safe than sorry.
