Gallstones Explained

Gallstones

Elimination Diet
Work with a knowledgeable professional to see whether food allergies are triggering your gallbladder attacks. Eggs, pork, and onions are common culprits.

Gallbladder attacks (though not the stones themselves) have been reported to result from food allergies. The one study to examine this relationship found that all of the participants with gallbladder problems showed relief from gallbladder pain when allergy-provoking foods were identified and eliminated from the diet.¹² Eggs, pork, and onions were reported to be the most common triggers. Pain returned when the problem foods were reintroduced into the diet. Doctors can help diagnose food allergies.

Coffee
Coffee increases bile flow and therefore might reduce the risk of gallstones. Caffeine appears to be the protective ingredient, as decaffeinated coffee has not been linked with any protection.

Coffee increases bile flow and therefore might reduce the risk of gallstones. In a large study of men, those drinking two to three cups of regular coffee per day had a 40% lower risk of gallstones compared with men who did not drink coffee.¹³ In the same report, men drinking at least four cups per day had a 45% reduced risk. Caffeine appears to be the protective ingredient, as decaffeinated coffee consumption was not linked with any protection. People at risk for gallstones who wish to consider increasing coffee drinking to reduce risks should talk with a doctor beforehand. Caffeinated beverages can aggravate symptoms of insomnia, peptic ulcer, panic attacks, and a variety of other conditions.

Wheat Bran
Decrease cholesterol build-up in the bile by eating more wheat bran–containing foods, such as some cereals. Drink plenty of water when you eat bran.

Constipation has been linked to the risk of forming gallstones.¹⁴ When constipation is successfully resolved, it has reduced the risk of gallstone formation.¹⁵ Wheat bran, commonly used to relieve constipation when combined with fluid, has been reported to reduce the relative amount of cholesterol in bile of a small group of people whose bile contained excessive cholesterol (a risk factor for gallstone formation).¹⁶ The same effect has been reported in people who already have gallstones.¹⁷ Doctors sometimes recommend two tablespoons per day of unprocessed Miller’s bran; an alternative is to consume commercial cereal products that contain wheat bran. Bran should always be accompanied by plenty of fluid. Adding more bran may cause gastrointestinal symptoms in some people. If this occurs, consult a doctor.

Cholesterol
Some studies link cholesterol to the risk of gallstones. Eating more vegetables and fiber while avoiding eggs may reduce your risk.

Cholesterol is the primary ingredient in most gallstones. Some,¹⁸ but not all,¹⁹ research links dietary cholesterol to the risk of gallstones. Some doctors suggest avoiding eggs, either because of their high cholesterol content or because eggs may be allergenic. (See the discussion about gallstones and allergies below.) A recent study of residents of southern Italy found that a diet rich in sugars and animal fats and poor in vegetable fats and fibers was a significant risk factor for gallstone formation.²⁰

Vegetarian
Choose a low-fat vegetarian diet rich in vegetables and beans.

Most studies report that vegetarians are at low risk for gallstones.²¹ In some trials, vegetarians had only half the gallstone risk compared with meat eaters.²²^,23 Vegetarians often eat fewer calories and less cholesterol. They also tend to weigh less than meat eaters. All of these differences may reduce gallstone incidence. The specific factors in a vegetarian diet that account for a low risk of gallstone formation remain somewhat unclear and may only be present in certain vegetarian diets and not others. For example, some studies have found that vegetarians eating a high vegetable fat diet had elevated rather than reduced risks of gallstone formation.²⁴^,25
