Irritable bowel syndrome (IBS) is a common digestive disorder that affects the large intestine. Symptoms include abdominal pain, bloating, gas, diarrhea, and constipation. Many people with IBS look to diets like juicing to help manage their symptoms. But is juicing good for IBS? Here’s a comprehensive look at the pros and cons of juicing with IBS.
What is IBS?
IBS is characterized by chronic, recurrent symptoms related to bowel movements and abdominal discomfort. It is considered a functional gastrointestinal disorder, meaning there is no structural damage to the digestive system. The exact causes of IBS are unknown, but factors like genetics, diet, stress, anxiety, gut microbiome imbalance, and intestinal hypersensitivity are thought to play a role.
There are three main types of IBS:
- IBS with constipation (IBS-C)
- IBS with diarrhea (IBS-D)
- IBS with mixed bowel habits (IBS-M)
Treatment focuses on managing symptoms through diet modifications, stress management, certain medications, probiotics, and other lifestyle changes.
What is Juicing?
Juicing refers to extracting the nutritious juices from fruits and vegetables, while removing the fiber. This is typically done using a juicer appliance that spins and crushes produce to separate the liquid juice from the pulp.
The resulting juice is very concentrated in vitamins, minerals, phytonutrients, and antioxidants from the produce. However, juicing also removes the beneficial fiber content. The fiber is important for gut health, as it feeds the good bacteria in the intestines.
Potential Benefits of Juicing with IBS
There are some potential advantages to incorporating juicing into an IBS diet:
- Increased nutrient absorption – The nutrients in juice are thought to be easier to digest and absorb without the fiber content.
- Phytonutrients – Juices made from fruits and veggies provide concentrated amounts of plant nutrients and antioxidants that can help reduce inflammation.
- Gentle on the digestive system – The nutrients from juices may place less stress on the GI tract than solid food.
- Allows greater vegetable intake – Juicing can help people consume larger quantities of vegetables.
- Supports gut healing – The nutrients in juice may help repair gut barrier function.
- Alternative to raw produce – Some people have trouble digesting raw fruits and veggies. Juicing provides an option for consuming produce without irritation.
Let’s explore these potential juicing benefits for IBS further:
Increased Nutrient Absorption
Because juicing removes insoluble fiber, some believe the nutrients can be absorbed better. For people with IBS, poor nutrient absorption is common. This is due to inflammation, intestinal permeability, and rapid transit times.
Drinking nutrient-dense juices may allow vitamins, minerals, and phytonutrients to be assimilated more easily compared to eating whole fruits and vegetables. However, more research is needed on juicing and absorption rates.
Phytonutrients and Anti-Inflammatory Compounds
Juices extracted from fresh produce provide concentrated amounts of beneficial plant nutrients and antioxidants. These include polyphenols, flavonoids, carotenoids, and other compounds with antioxidant and anti-inflammatory effects.
Reducing intestinal inflammation is important for managing IBS symptoms. The phytochemicals in juices may help by suppressing inflammatory pathways.
The nutrients in juice don’t require extensive digestion by the body. The fruit and vegetable fibers have already been broken down. This means juicing doesn’t place a heavy burden on the digestive system.
The nutrients can be absorbed directly without needing to go through the full digestive process. For people with IBS suffering from abdominal pain, juicing may be better tolerated than eating high-fiber foods.
Higher Vegetable Intake
Getting adequate vegetables is important for gut health. However, many people struggle to consume the recommended daily amounts. Juicing makes it easier to take in multiple servings of vegetables in one sitting.
By juicing things like spinach, kale, carrots, tomatoes and broccoli, it’s possible to get 3-4 servings of veggies at once. Higher vegetable intake provides important nutrients that can help heal intestinal inflammation.
Supports Gut Lining Repair
Leaky gut syndrome is common in IBS. This is when gaps form in the intestinal lining, allowing toxins, microbes, and undigested food particles to enter the bloodstream. This leads to widespread inflammation.
The nutrients in vegetable juices, including vitamins A, C, and E, zinc, selenium, and glutathione, may help rebuild the gut barrier and restore proper intestinal permeability.
Alternative to Raw Produce
Many people with IBS have difficulty tolerating high-fiber foods, especially raw fruits and vegetables. Insoluble fiber can be hard on the digestive system for some with IBS.
Juicing provides a way to get the benefits of produce without the high-fiber content. The insoluble fiber has been removed but the nutrients remain. For those unable to eat raw veggies, juicing is a good option.
Potential Downsides of Juicing with IBS
While juicing does have some benefits, there are also some potential downsides to consider:
- Reduced fiber intake – Juices lack the gut-healthy fiber that whole fruits and veggies provide.
- Blood sugar spikes – The natural sugars in juices can cause rapid increases in blood glucose without the fiber.
- Nutrient deficiencies – Juices don’t contain all the nutrients available from produce.
- Loss of beneficial enzymes – Enzymes can be destroyed by heat from juicing.
- High oxalate juices – For some, high-oxalate juices like spinach may irritate the gut.
Let’s explore these drawbacks in more detail:
Lack of Fiber
While removing fiber makes nutrients more bioavailable, fiber is still extremely important for bowel regularity, gut microbiome balance, and satiety. Juices contain little to no fiber.
This is problematic for IBS-C sufferers dealing with constipation. Fiber helps move things along the digestive tract. Without adequate fiber, constipation symptoms could worsen.
Blood Sugar Spikes
The natural sugars in fruit and vegetable juices can cause rapid spikes in blood glucose and insulin levels without fiber’s tempering effects. This is especially true for fruit-based juices.
High glycemic loads from juices could exacerbate IBS symptoms like gas, bloating, and diarrhea. Those with diabetes or blood sugar regulation issues should be cautious with juicing and monitor blood sugar closely.
While juices contain vitamins and plant nutrients, they lack protein, fat, and other important compounds. Whole fruits and vegetables provide a complete nutritional package.
Important minerals like magnesium, phosphorus, potassium, and selenium are reduced through the juicing process. The gut microbiome benefits from all parts of produce, including the skins, seeds, and pulp.
Loss of Enzymes
The heat generated by juicers may destroy beneficial digestive enzymes from produce. Enzymes help the body properly break down and utilize nutrients. This improves gut health and reduces inflammation.
High Oxalate Levels
For some with leaky gut, high-oxalate juices like spinach, beet greens, and Swiss chard may irritate the intestines. Oxalates bind to minerals like calcium and can promote kidney stone formation in sensitive individuals.
Those struggling with oxalate sensitivity may want to avoid or limit high-oxalate juices. Other gut-friendly juices include cucumber, carrots, lettuce, aloe vera, and low-sugar fruits like berries.
Tips for Juicing with IBS
If you want to try juicing while managing IBS, here are some tips to make it work for you:
- Consume juice as part of a balanced, high-fiber diet
- Include gut-healthy fruits like berries and pears
- Choose low-FODMAP veggies like carrots, cucumber, lettuce
- Add anti-inflammatory herbs like mint, parsley, basil
- Include collagen peptides or bone broth for protein
- Drink only fresh juices, not store-bought juices high in preservatives
- Avoid high-sugar fruits like mangos and grapes
- Monitor blood sugar and insulin response
- Supplement with probiotics and digestive enzymes
- Drink juices slowly for better digestion and absorption
Having juices along with high-fiber foods provides a balance of gentle nutrients from juices plus gut-supporting fiber. Making your own fresh juices at home gives you control over ingredients.
Sample 1-Day Juicing Menu for IBS
Here is an example 1-day juicing menu for incorporating juices into an IBS diet:
Fiber-rich oatmeal topped with banana and cinnamon
Glass of beet, carrot, ginger juice
Handful of walnuts

This sample menu provides a balanced mix of fiber and juices to support IBS symptom relief.
The Bottom Line
Juicing can offer some benefits for people with IBS when done properly alongside a high-fiber diet. The biggest advantages of juicing include increased nutrient absorption, phytonutrients, and gentle digestion.
However, lack of fiber, blood sugar spikes, and missing nutrients are downsides to consider. Those with IBS interested in juicing should start slowly, pay attention to ingredients, and monitor their symptoms. Avoid going overboard with juicing and depriving yourself of valuable dietary fiber.
While juicing shouldn’t replace eating whole fruits and vegetables long-term, it can be helpful for providing concentrated nutrition, aiding nutrient assimilation, and allowing greater vegetable intake when tolerated. This can support gut healing in addition to other lifestyle measures to manage IBS.
