Can you eat duck if you have a stye?
Generally, it is acceptable to eat duck in moderation when experiencing a stye, but attention should be paid to the cooking method, avoiding spicy or greasy preparations. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed analysis is as follows:

Duck meat contains high-quality protein that provides nutritional support and helps maintain normal physiological functions, posing no direct negative impact on stye recovery. When prepared using light cooking methods such as steaming or boiling—especially with excess fat removed—moderate consumption can supply essential nutrients without aggravating ocular inflammation, aligning with the need for a bland diet during a stye.
However, if duck meat is prepared with spicy seasonings, deep-fried, or cooked in rich sauces (high in oil and sugar), it may increase bodily strain, potentially exacerbating inflammation and worsening symptoms such as redness, swelling, and pain associated with the stye, thereby delaying recovery. Additionally, excessive intake of duck meat—even when prepared in a light manner—may impair metabolism due to digestive burden, indirectly hindering recovery.
During a stye, in addition to carefully choosing how duck meat is prepared, it's important to maintain an overall light diet, consume more fresh fruits and vegetables, avoid spicy, stimulating, and oily foods, keep the eyes clean, refrain from rubbing the eyes, and follow medical advice regarding medication to promote healing.
