Can fish bladder improve immunity?
Generally speaking, fish bladder can play a certain auxiliary role in enhancing immunity, but its effect is limited. It should be consumed in moderation. Detailed analysis is as follows:

Fish bladder is a common ingredient rich in collagen, protein, and various minerals. Protein is an important component of the immune system and provides the building blocks for the synthesis of immune cells. Zinc, a mineral found in fish bladder, helps regulate immune function. Consuming fish bladder in moderation can supply these nutrients and assist in maintaining normal immune system function.
However, excessive consumption of fish bladder may lead to increased gastrointestinal burden due to its relatively high cholesterol and fat content, potentially causing discomfort such as bloating and indigestion, and may also increase the body's metabolic burden. Additionally, if fish bladder is prepared using overly greasy methods, it may affect nutrient absorption and overall health. Therefore, it's important to control portion sizes and opt for lighter cooking methods.
In daily life, it is important to develop healthy eating habits by combining fish bladder with other protein- and vitamin-rich foods, such as eggs and vegetables. Combining this with moderate exercise can help maintain immune system function and promote overall health.
