What is one rule that Jehovah's Witnesses must follow regarding food?

Jehovah's Witnesses adhere to a specific dietary rule that involves abstaining from blood. This is based on their interpretation of biblical texts, particularly Acts 15:28-29 and Leviticus 17:10-14, which indicate that they are to abstain from consuming blood or food products that contain blood. This means that not only do they avoid blood transfusions, but they also refrain from eating foods that have blood in them, such as certain types of meat that have not been drained properly. This rule is a fundamental aspect of their faith and directly influences their dietary choices, making it a critical point of understanding for anyone studying the food practices of Jehovah's Witnesses.
