Tomatoes and fish are generally safe to consume, but attention should be paid to the quantities eaten. Tomatoes, belonging to the vegetable category, are rich in vitamins C and A, dietary fiber, and various other nutrients. Eating tomatoes in moderation can supplement the body's nutrition and enhance immune function to a certain extent. Fish, categorized as a meat product, is abundant in high-quality protein, calcium, zinc, and various other nutrients. Consuming fish can nourish the body and promote brain development. Eating tomatoes and fish together may not cause chemical reactions in the gastrointestinal tract and can promote gastrointestinal motility, improving symptoms such as abdominal bloating and constipation. If gastrointestinal discomfort occurs after consuming tomatoes and fish, it is necessary to stop eating them promptly. If there is an allergic tendency to any of these foods, avoid consumption to prevent symptoms such as rash and skin itchiness. In daily life, it is important to develop good eating habits by consuming more easily digestible liquid foods. After meals, one can walk according to their physical condition to promote gastrointestinal motility and accelerate the digestion and absorption of nutrients. Additionally, it is advisable to eat smaller meals more frequently and avoid eating too quickly, which can prevent fish bones from getting stuck in the throat and causing coughing and expectoration.
