Can fish be eaten with onions?
Under normal circumstances, fish can be consumed together with onions, but it is important to follow the principle of moderation when ingesting them. A detailed analysis is as follows:

Fish is rich in high-quality protein, Omega-3 fatty acids, and various minerals, while onions contain sulfides, vitamin C, and dietary fiber. Combining the two can provide protein and antioxidant substances. In daily cooking, they are often used together in dishes such as steamed fish and onion-stewed fish soup. Normally, moderate consumption by healthy individuals typically does not cause discomfort and can provide diverse nutrients to the body.
Individuals allergic to fish or onions may experience allergic reactions such as skin rashes and rapid breathing when consuming them together. Consumption should be stopped immediately, and physical reactions should be observed. Patients with gout or hyperuricemia should pay attention to the purine content in fish, as consuming large amounts of certain high-purine fish species together with onions might increase the risk of elevated uric acid levels. For those with weak gastrointestinal function, the pungent components in onions combined with the high protein content in fish may increase digestive strain, leading to discomfort such as bloating and diarrhea. It is recommended to reduce intake and avoid consuming them on an empty stomach.
Therefore, in daily diets, it is important to pay attention to your health condition and any allergies, properly combine foods, and avoid allergens. Additionally, maintaining a balanced diet and diverse food intake, along with eating more fresh vegetables and fruits, can help promote overall health.
