The gallbladder is a small organ located below the liver. It stores bile produced by the liver, and releases the bile into the small intestine to help digest food.

The gallbladder is a sensitive organ, and maintaining a healthy diet full of nutrient-dense foods helps keep it in perfect health. Certain foods can protect and promote a healthy gallbladder, while others increase the likelihood of problems like inflammation or gallstones.

If your gallbladder isn’t kept in good health, it may need to be removed. So eating a gallbladder-healthy diet is essential.

For a healthy gallbladder, incorporate the following foods into your diet:

  • bell peppers
  • citrus fruits
  • dark, leafy greens
  • tomatoes
  • milk
  • sardines
  • fish and shellfish
  • low-fat dairy
  • beans
  • nuts
  • lentils
  • tofu
  • tempeh

Eating a healthy, well-balanced diet full of fruits and vegetables is the best way to improve and protect your gallbladder’s health. Fruits and vegetables are full of nutrients and fiber, the latter of which is essential to a healthy gallbladder.

Some of the listed foods are either high in vitamin C, calcium, or B vitamins, which are also good for your gallbladder.

It’s thought that eating more plant-based protein could also help prevent gallbladder disease. Foods like beans, nuts, lentils, tofu, and tempeh (as long as you aren’t allergic to soy) are excellent alternatives for red meat.

Avoid the following foods for a healthy gallbladder diet:

  • vegetable oil
  • peanut oil
  • refined white foods (breads, pastas, etc.)
  • foods high in fat
  • processed foods

You should avoid certain foods to help protect your gallbladder. The biggest problem foods are high-fat and processed foods. Foods that are greasy or fried in oils like vegetable oil and peanut oil are more difficult to break down and can cause gallbladder problems.

Foods with trans fats, like those in processed or commercially baked products, can also be harmful to gallbladder health.

Avoiding refined white foods, like white pastas, breads, and sugars, can protect your gallbladder. You should also avoid alcohol and tobacco.

If you need to have your gallbladder removed, you’ll likely experience diarrhea and loose stools in the weeks after surgery. This is due to the more continuous release of bile into your intestines.

To reduce these side effects, avoid these foods after gallbladder surgery:

  • foods containing more than 3 grams of fat
  • greasy, fried, or processed foods
  • cream sauces or gravies
  • full-fat dairy

Instead, eat high-fiber foods that are low in fat. According to the Mayo Clinic, you should eat foods with less than 3 grams of fat per serving. Increase your fiber slowly, and start with soluble fiber, like oats. You can also eat smaller meals on a more frequent basis.

There are two primary types of gallbladder problems: cholecystitis (inflammation of the gallbladder) and cholestasis (gallstones). Some people with gallstones don’t experience any symptoms. In those that do, symptoms of gallbladder problems can include:

  • pain on the upper right side of the abdomen, especially following meals and eating fatty foods
  • loss of appetite
  • nausea
  • vomiting
  • jaundice, if the gallbladder ducts are blocked
  • low-grade fever
  • tea-colored urine
  • light-colored stools

Gallstones can be painful. If large enough, they can also block the duct that leads out of the gallbladder. Over time, this can become life-threatening. In these cases, removal of the gallbladder is often necessary.

Women are more likely to develop gallstones than men. Pregnant women, women using hormonal birth control, and women who use hormone replacement therapy are at increased risk for the formation of gallstones. Other risk factors include:

Gallbladder problems can be painful and, in some cases, dangerous. Eating the right foods — and avoiding the wrong ones, namely those high in fat — can help improve and protect the health of your gallbladder. Ultimately, a diet for a healthy gallbladder will benefit your overall health, keeping your whole body healthier in the long run.
