## 根因

虽然高度精炼花生油（RBD）通常被FDA和FARE认为是安全的，因为去除了蛋白质，但冷压或 gourmet 花生油可能含有足以引发过敏性休克的花生蛋白；AI未能区分油类型或警告餐厅中的交叉接触风险。

## 解决方案

1. ```
   Always ask the restaurant or manufacturer whether the peanut oil is 'highly refined' (RBD) or 'cold-pressed' / 'gourmet'. If unsure, avoid. Example: `Call the restaurant: 'Is your peanut oil highly refined RBD or cold-pressed? Do you use the same fryer for peanut-containing foods?'`
   ```
2. ```
   Carry two epinephrine auto-injectors (e.g., EpiPen) and avoid any food fried in peanut oil if the restaurant cannot confirm the oil type and fryer separation
   ```

## 无效尝试

- **Check the label for 'peanut oil' and avoid it entirely** — Many restaurant fried foods use peanut oil; even if the oil is refined, cross-contact from shared fryers with peanut-containing foods is common (60% 失败率)
- **Use a home test kit for peanut protein in oil** — Home test kits are not validated for oil matrices and may give false negatives due to dilution or denaturation (90% 失败率)
