Can I eat river crab after receiving the COVID-19 vaccine?

Generally speaking, it is safe to eat river crabs after receiving a COVID-19 vaccine, but moderation is advised. The details are as follows:

After receiving the COVID-19 vaccine, there are usually no specific dietary restrictions. River crabs are high-protein foods rich in nutrients. If you are not allergic to river crabs under normal circumstances and do not experience gastrointestinal discomfort or other adverse reactions after vaccination, consuming them in moderation can provide high-quality protein and other nutrients, helping your body maintain a good condition post-vaccination.

However, it should be noted that river crabs are common allergenic foods, and some individuals may experience allergic reactions after consumption. After vaccination, the immune system is relatively active. If an allergic reaction occurs after eating river crabs, it might be difficult to determine whether it was caused by the vaccine or the food, complicating subsequent diagnosis and management. Therefore, if you choose to eat river crabs after vaccination, ensure you have no history of seafood or river crab allergies, and strictly control the amount consumed. As river crabs are considered "cold" in nature according to traditional beliefs, excessive intake may lead to indigestion, abdominal pain, diarrhea, or other adverse effects.

After receiving the COVID-19 vaccine, it is recommended to increase intake of protein-rich foods such as eggs, milk, and lean meat to support bodily repair. Eating more fresh vegetables and fruits will help ensure sufficient supply of vitamins and minerals. At the same time, avoid spicy, greasy, and irritating foods.
