"Nut-Free" refers to products or environments that do not contain any type of nuts, including peanuts, almonds, walnuts, and others. This designation is crucial for individuals with nut allergies, as even small amounts of nuts can trigger severe allergic reactions. In food labeling, "nut-free" indicates that the item was made without nuts and has been processed in a way to avoid cross-contamination. Many schools and restaurants adopt nut-free policies to ensure the safety of those with allergies, creating a safer space for everyone.
