Gallstones are primarily composed of cholesterol.

Explanation

Gallstones are solid particles that form in the gallbladder, and the most common type is cholesterol gallstones, which are typically yellow-green in color. They form when there is too much cholesterol in the bile, which can be due to factors like obesity, diabetes, rapid weight loss, or high-fat diets. Other types of gallstones include pigment stones, which are made of bilirubin and are typically darker in color, often associated with liver diseases.

Gallstones made of calcium and protein are less common, and sodium does not play a significant role in the composition of gallstones. Understanding the composition of gallstones is crucial as it helps in diagnosing and determining the treatment options for gallstone disease.
