Tree nuts
Walnuts, almonds, pecans, hazelnuts, cashews, pistachios, Brazil nuts, and pine nuts may all be off limits if you have a tree nut allergy. These must be clearly labeled in packaged foods, but nuts are more difficult to avoid in restaurants and bakeries. Nutmeg, water chestnuts, sunflower seeds, and sesame are not nuts and can be eaten safely. Be aware that tree nut oils, such as shea oil, may be used in skin lotions.
