Generally clams and other small seafood are not recommended during lung adenocarcinoma treatment, but sea fish and sea shrimp can be consumed appropriately. Lung adenocarcinoma patients may be in a weaker state after surgery, radiotherapy, chemotherapy, or in a state of long-term hospitalization. Therefore, they need to pay attention to the nutritional support brought by diet. If lung cancer patients can have normal diet, they can consume sea fish and sea shrimp in moderation without affecting the treatment to replenish protein and other nutrients of the organism and promote the repair of the body. However, it is not recommended to eat clams, scallops, oysters and other small seafood. This is due to the high purine content in small seafood such as oysters, scallops, etc. Their metabolism produces a large amount of uric acid, which increases the burden of kidneys. Lung adenocarcinoma patients are advised to consume seafood in moderation under the guidance of physicians and actively cooperate with doctors to formulate appropriate treatment and diet programs.
