Dietary Intake and Cholelithiasis: A Review

Area of Science:

• Gastroenterology and Nutritional Science
• Epidemiology

Background:

• Gallbladder disease (GBD) is a common gastrointestinal disorder with multifactorial etiology.
• Dietary factors are recognized as potentially modifiable risk factors in gallstone pathogenesis.

Purpose of the Study:

• To systematically review epidemiological studies evaluating the role of diet in gallbladder disease prevention.
• To assess the impact of specific dietary components on gallstone formation.

Main Methods:

• Systematic review of English-language studies from 1973-2018 in the Med-line database.
• Analysis of epidemiological evidence on dietary factors including fatty acids, cholesterol, carbohydrates, protein, fiber, alcohol, nuts, and coffee.

Main Results:

• High intake of simple sugars and saturated fats correlates with increased gallstone formation risk.
• Intake of protein, fiber, nuts, coffee, and moderate alcohol is associated with reduced gallstone risk.
• Fat and cholesterol intake show variable associations, requiring further investigation.

Conclusions:

• Gallbladder disease is influenced by a complex interplay of dietary factors.
• While specific recommendations are pending further research, adopting healthy dietary patterns may support gallbladder function and potentially reduce GBD risk.
