Gallbladder-Friendly Fiber Benefits

We all know we need fiber as a part of our diet. But until a few years ago, dietary fiber was not given the attention it deserves, unlike other food components such as fats, sugar, and proteins. Some researchers think it’s probably because fiber is indigestible and of negligible nutrient value. Or maybe it was because it is easily accessible? Despite its availability, most Americans do not get the recommended amount of dietary fiber in this day and age. The suggested daily value is 25g per day based on a 2,000 calorie diet. It may seem easy to achieve, but it is often missed with the proliferation and popularity of processed foods. The average individual only consumes about half of the recommended amount daily. Luckily, with the exponential increase in the number of studies on fiber benefits as part of our daily diet, more and more authorities have taken an interest in this roughage.

Fiber Benefits

The FDA defines dietary fiber as a type of carbohydrate found in plant foods made up of many sugar molecules linked together. It affects various physiologic functions like intestinal regularity, satiety, reducing cholesterol, and resolving numerous digestive issues. High fiber intake is associated with the prevention and treatment of chronic diseases like diabetes, heart disease, obesity, and certain types of cancer. But did you know that dietary fiber can also reduce the risk of gallstones? It also helps in improving overall gallbladder health.

How Does Fiber Help with the Gallbladder?

According to a study published in the American Journal of Gastroenterology, sufficient insoluble fiber intake may decrease gallbladder surgery risk among women. Participants with the highest amounts of dietary fiber were 13% less likely to have their gallbladders taken out. The type of fiber also influenced the output. When researchers simultaneously controlled soluble and insoluble fiber consumption, insoluble fiber intake proved most beneficial. This research was conducted by observing 69,000 women for over 16 years.

A separate study published in the American Journal of Surgery also showed the benefits of fiber for the gallbladder. The experiment on dogs placed on a cholesterol-supplemented lithogenic (gallstone-forming) diet showed that the administration of dietary soluble fiber over six weeks inhibited cholesterol stone formation by reducing the cholesterol saturation levels in the bile. This protective effect is associated with a decrease in cholesterol that contributes to bile toxicity.

Obese patients on a rapid weight loss diet are prone to developing gallstones. A study done over five weeks showed that subjects who had a fiber-rich diet were protected from the accumulation of biliary sludge despite the fact that both obesity and rapid weight loss pose a huge risk for the development of gallstones.


4 Fiber Benefits for the Gallbladder

1. Reduces Cholesterol Levels

2. Boosts Immune System

3. Detoxifies the Bile

4. Reduces Inflammation

Reduces Cholesterol Levels

Reducing cholesterol levels is one of the more famous fiber benefits for the gallbladder. Although the cholesterol-busting mechanism of fiber is not yet fully understood, the hypothesis is that dietary fiber significantly impacts bile acid metabolism. Soluble fiber binds to the bile acids in the body and speeds up transit time to excretion. When this happens, the amount of bile re-circulated is decreased, requiring the liver to use more cholesterol to produce more bile acids, thereby reducing the amount of cholesterol that the body uses to make low-density lipoproteins. Aside from taking part in the stimulation of bile acid production, fibers also help in controlling cholesterol by increasing bowel elimination

Boosts Immune System

Fiber helps boost our body’s natural disease-fighting abilities. Aside from helping in the detoxification process through its effect on the bile and excretion, a good amount of dietary fiber in our system keeps our gut flora balanced. When soluble fibers ferment, it forms short-chain fatty acids (SCFA) that are important in the production of components needed for immune protection. Of course, it also helps that most foods naturally high in fiber are the same food sources high in vitamins, minerals, antioxidants, and phytonutrients.

It helps Prevent Toxic Bile and Facilitates Healthy Bile Flow

A low-fiber diet can contribute to increased toxic levels in the body because of fiber’s role in reducing cholesterol, metabolism of bile acid, and elimination of body waste. As the studies cited earlier explain, fiber helps decrease toxic bile in the biliary system. It also prohibits sludge accumulation, ensuring healthy bile flow and preventing gallstone formation.

Reduces Inflammation

There are direct and indirect fiber benefits as our body deals with inflammation. Indirectly, naturally occurring phytonutrients found in most fiber-rich foods help reduce inflammation. Some studies also prove that fiber directly impacts inflammatory diseases and oxidative stress. One example is the data from 27,312 women from the Iowa Women’s Health Study showing the inverse association between inflammation and fiber ingestion daily. Similar research among diabetic women of the Nurse’s Health Study showed that subjects consuming more fibers had lower values of inflammatory markers. Also, due to its overall effect on digestion, dietary fibers help increase the body’s production of anti-inflammatory cells called cytokines.

How Can We Get More Fiber?

The most commonly consumed foods, like processed and fast foods, are low in dietary fiber. Therefore, we must consciously and intentionally meet our dietary fiber requirements daily. The ideal way of taking it is by distributing and taking it in small snacks and meals throughout the day. Below are common sources of dietary fiber:

Soluble Fiber

As the name suggests, soluble fiber dissolves in water but is indigestible. It is not absorbed into the bloodstream but is generally fermented by bacteria in the lower intestine to form short-chain fatty acids. Types of soluble fiber include beta-glucan, pectin, natural gums, and inulin. The items below are rich in soluble fiber. Please note, however, that these are also in our “do-not-eat list under the Gallbladder Diet.

  • Oatmeal
  • Rice bran
  • Barley
  • Nuts and Seeds
  • Beans, lentils, and peas
  • Citrus fruits
  • Turnips

Here are some foods high in soluble fiber but are also gallbladder-friendly:

  • Apples
  • Berries
  • Papaya
  • Pears
  • Pomegranates
  • Strawberries
  • Swiss chard
  • Dandelion greens
  • Brussel sprouts
  • Beet greens
  • Celery
  • Carrots
Insoluble fiber

On the other hand, Insoluble fiber does not dissolve in water and is less fermentable. It is also indigestible, so it passes through the intestines almost intact but works like a sponge that pulls water into the stool, making it easier to excrete. It can also delay glucose or sugar absorption, resulting in more even blood sugar levels, increase the fecal weight to help stool pass more quickly and regularly, and help control and balance the pH in the gut. Some insoluble fibers include cellulose, lignin, pectins, and hemicelluloses. Below are examples of gallbladder foods high in insoluble fiber:

  • Globe artichokes
  • Rice
  • Beets
  • Spinach
  • Flax seeds
  • Chia seeds

Among these, I’d like to highlight the benefits of globe artichokes. Aside from being an excellent source of fiber (one serving contains a quarter of the daily amount of fiber recommended for adults), it also contains inulin. Inulin is a prebiotic beneficial for good bacteria in the gut.

Various studies and experiments prove the numerous physiological and subsequent health benefits of regular dietary fiber intake. It is not just a good ally for a better gallbladder. It is also an effective booster for overall health. Just a reminder, if you have gallbladder disease, it is essential to cross-check this list of fiber-rich foods to the gallbladder diet plan. And if you need help in digesting these fiber-rich foods, try taking some Digestive Enzymes to go with them. V
