A basic gallbladder diet consists of lean protein, high fiber and low cholesterol, according to WebMD. Staples include fresh produce, fish and low-fat dairy products. Studies also highlight the benefits of consuming caffeinated coffee and a daily serving of peanuts to reduce the emergence of gallstones and other gallbladder issues.
Soluble fiber, found in wheat and oats, slowly implemented into a gallbladder diet increases fiber consumption and regulates bowel movements, explains Mayo Clinic. Smaller, frequent meals with low-fat options allow for better digestion, thus decreasing gas and abdominal discomfort. Greasy foods that are high in fat require the gallbladder to work harder to produce enough bile to aid in digestion.
