I now have excellent textbook content from Yamada's Textbook of Gastroenterology and Mulholland & Greenfield's Surgery. Here is a thorough, evidence-based dietary guide for gallstones:

Diet for Gallstones

Gallstones form primarily due to cholesterol supersaturation of bile, gallbladder stasis, and disturbed biliary lipid metabolism. Diet plays a direct role in all three. The following guidance applies both to preventing gallstone formation and to managing symptoms if you already have stones.

Foods to INCLUDE

1. High-Fiber Foods

Dietary fiber reduces biliary hydrophobic bile acids and helps regulate cholesterol metabolism. Aim for 25-35 g of fiber per day.

Whole grains (oats, brown rice, whole wheat bread, barley)
Legumes (lentils, chickpeas, beans)
Vegetables (broccoli, spinach, carrots, cauliflower)
Fruits (apples, pears, berries, bananas)

2. Fruits and Vegetables

Fruits and vegetables are independently protective through their antioxidant content and influence on biliary lipid metabolism. - Yamada's Textbook of Gastroenterology, p. 1833

3. Healthy (Unsaturated) Fats

Poly- and monounsaturated fats are protective - they stimulate gallbladder contraction, prevent bile stasis, and improve biliary lipid composition. - Yamada's Textbook of Gastroenterology, p. 1833

Olive oil (extra virgin, in small amounts)
Avocados
Nuts (walnuts, almonds) - nuts specifically are noted as protective
Fatty fish (salmon, mackerel, sardines - rich in omega-3 fatty acids)

4. Coffee and Caffeine

Coffee consumption has a protective effect on gallstone formation by influencing biliary lipid metabolism. 1-2 cups of coffee per day is reasonable. - Yamada's Textbook of Gastroenterology, p. 1833

5. Vitamin C-Rich Foods

Vitamin C (ascorbic acid) appears protective against gallstone formation.

Citrus fruits (oranges, lemons)
Bell peppers, kiwi, tomatoes

6. Calcium-Rich Foods

A high-calcium diet helps reduce biliary hydrophobic bile acids. - Yamada's Textbook of Gastroenterology, p. 1833

Low-fat dairy (skim milk, low-fat yogurt)
Fortified plant milks, tofu, leafy greens

7. Adequate Hydration

Drink 8-10 glasses of water per day. Good hydration helps prevent bile concentration and promotes gallbladder emptying.

Foods to LIMIT or AVOID

1. High-Fat and Fried Foods

Fatty meals trigger gallbladder contraction and can precipitate biliary colic in those with existing stones. Saturated and trans fats also promote cholesterol supersaturation of bile.

Fried foods (french fries, fried chicken)
Red meat with visible fat
Full-fat dairy (butter, cream, full-fat cheese)
Processed meats (sausages, bacon)
Pastries, biscuits, cakes

2. Refined Carbohydrates and Sugar

High sugar intake raises triglycerides and promotes cholesterol biliary secretion.

White bread, white rice, sugary cereals
Sweets, candy, soft drinks, fruit juices
Pastries and commercially baked goods

3. Rapid Weight Loss Diets

While obesity is a major risk factor for gallstone development, losing weight too fast (more than 1.5 kg/week) paradoxically increases gallstone risk by increasing biliary cholesterol excretion. - Yamada's Textbook of Gastroenterology, p. 1833; Mulholland & Greenfield's Surgery, p. 2853

Avoid very low-calorie crash diets
Weight loss should be gradual: target 0.5-1 kg/week

4. Skipping Meals / Prolonged Fasting

Fasting and irregular meal patterns cause gallbladder stasis - bile sits in the gallbladder longer and becomes concentrated, promoting stone formation. - Yamada's Textbook of Gastroenterology, p. 1833

Eat 3 small-to-moderate meals regularly, plus healthy snacks if needed
Never skip breakfast

5. Alcohol (in Excess)

Small amounts of alcohol may actually be mildly protective, but heavy alcohol use promotes liver dysfunction and pigment stone formation.

Meal Pattern Tips

Tip	Why it Matters
Eat small, frequent meals	Prevents gallbladder stasis from prolonged fasting
Never skip meals	Regular eating stimulates CCK release and gallbladder emptying
Keep fat portions small per meal	Reduces intensity of gallbladder contraction
Cook by steaming, baking, or boiling	Avoids adding saturated fats
Read food labels	Watch for hidden trans fats and palm/coconut oil

Weight Management

Obesity is one of the strongest modifiable risk factors for gallstones. If overweight, aim for gradual weight loss through a balanced diet and regular physical activity. Physical activity specifically reduces bile stasis and improves HDL cholesterol, both of which lower gallstone risk. - Yamada's Textbook of Gastroenterology, p. 1833

Sample Daily Menu

Breakfast: Oatmeal with berries and a handful of walnuts, green tea or coffee Mid-morning snack: An apple or pear Lunch: Grilled fish or chicken with steamed vegetables and brown rice Afternoon snack: Low-fat yogurt with a banana Dinner: Lentil soup or dal with whole wheat chapati and a vegetable side dish Throughout the day: 8-10 glasses of water

Important note: If you already have symptomatic gallstones and are experiencing biliary colic, dietary changes help manage symptoms but do not dissolve existing stones. Consult a gastroenterologist or surgeon regarding whether medical or surgical treatment (laparoscopic cholecystectomy) is needed. A meta-analysis in Clinical Gastroenterology and Hepatology found that diets higher in fat during calorie-restricted weight loss (combined with ursodeoxycholic acid when needed) actually help prevent new gallstone formation - showing fat intake should be moderate, not zero.
