Generally speaking, squid and onion can be consumed together, but moderation is important. The detailed explanation is as follows:

Squid is rich in nutrients such as protein and trace elements, while onions contain abundant vitamins, dietary fiber, and minerals. From a nutritional perspective, there is no obvious conflict between the two. Consuming them together can enhance both the taste and nutritional value of meals. During cooking, combining squid and onions can allow the sweetness of the onion to neutralize the fishy odor of the squid, thereby enhancing the overall flavor of the dish.

However, onions have a spicy flavor and excessive consumption may irritate the gastrointestinal tract, especially for individuals with gastrointestinal diseases such as gastritis or gastric ulcers, as excessive onion consumption may worsen symptoms. Additionally, squid is a high-protein food, and excessive consumption may increase the digestive burden, so individuals with indigestion should also consume it in moderation. Furthermore, individuals with a history of allergies to seafood or onions should avoid consuming them to prevent allergic reactions.

In daily diets, attention should be given to food diversity and balance, avoiding excessive intake of any single food item in order to maintain good health.
