Why can't soy products be eaten after gallbladder removal?

In general, there is no truth to the claim that people who have had their gallbladder removed cannot eat soy products. Patients can consume soy products, but should do so in moderation. The detailed explanation is as follows:

Soy products are high-protein, high-fiber foods rich in plant-based protein, minerals, and vitamins. These nutrients help meet the body's nutritional needs and support recovery. Especially after gallbladder removal, patients experience reduced bile secretion and diminished ability to digest fats, making high-protein, low-fat soy products a favorable choice. Additionally, soy products are relatively low in fat, so moderate consumption does not place excessive strain on digestion.

However, during the early stages following gallbladder removal, the biliary system has not yet fully adapted to the new pattern of bile excretion. Therefore, patients should consume soy products in moderation to avoid overconsumption, which may lead to indigestion symptoms such as bloating or abdominal pain. Moreover, attention should be paid to cooking methods: steaming, boiling, or stewing are recommended, while high-fat methods such as frying or sautéing should be avoided to minimize fat intake.
