10 Best Vegetables for IBS Symptoms

Approximately 12% of the North American population has been clinically diagnosed with irritable bowel syndrome or IBS.¹ From bloating to constipation to diarrhea to generalized abdominal pain, IBS can significantly impact one’s quality of life. And while there’s no one-size-fits-all diet to manage the chronic gastrointestinal condition, a low FODMAP diet is often recommended for those who have been diagnosed with IBS. 

The low FODMAP diet focuses on more than just fiber intake. It temporarily limits foods that trigger IBS symptoms, including fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. But in a condition that often requires significant restriction, it’s refreshing to focus on foods to incorporate into your diet to help ease symptoms, such as nutritious vegetables. In this article we’ll discuss some of the best vegetables for IBS symptoms to help ease some of the symptoms of IBS.

Irritable Bowel Syndrome Explained

Irritable bowel syndrome, commonly called IBS, is a chronic gastrointestinal condition that primarily affects the large intestine and often leads to discomfort and disruption of bowel movements. Its exact cause isn’t fully understood yet, but it’s characterized by a cluster of symptoms, including diarrhea (IBS-D), constipation (IBS-C), abdominal pain, cramping, and bloating.⁴ Its onset is believed to involve a combination of factors, including inflammation, disturbances in the gut microbiome, abnormal gastrointestinal motility, and heightened visceral sensitivity.

Certain factors, like genetics, may predispose some individuals to IBS. Interestingly, IBS appears to be more common in women than men, indicating hormones may play a role in the development and treatment of IBS.³ However, there is also a distinct connection between the brain and gut health via the gut-brain axis. Psychological demands, in the form of anxiety, depression, and stress, may contribute to the onset of IBS or exacerbate its symptoms through its impact on the gut. 

Dietary intake can also influence the onset of IBS. Consuming large amounts of high-fat or spicy foods or drinking excessive alcohol or caffeine may trigger symptoms of IBS over time. Irregular eating patterns or skipping meals may also disrupt digestion, potentially contributing to IBS symptoms. 

IBS-Friendly Foods for IBS

Food becomes a big focus for those affected by irritable bowel syndrome, as some foods trigger IBS symptoms. In a condition so significantly affected by food, restrictive diets often become the primary agenda for dietary management. 

However, there’s an extensive menu of IBS-friendly foods that can support digestive health and keep IBS symptoms at bay. The best foods for IBS include, but are not limited to:  

• Low-FODMAP Foods: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, or FODMAPs for short, are a group of carbohydrates that can stir up symptoms in those with IBS. Eating foods low in these carbs, such as citrus fruits, berries, proteins, and most vegetables, can alleviate IBS symptoms.
• Lean Proteins: Good sources of protein, like lean meats, are essential to a well-balanced diet, and they don’t usually cause flare-ups in those with IBS. Lean proteins may include but aren’t limited to chicken, fish, turkey, eggs, and tofu.
• Soluble Fiber Foods: Soluble fiber can help with regular bowel movements and reduce the frequency of diarrhea in those with IBS. It can be found in beans, oats, chia seeds, flaxseeds, nuts, and citrus fruits. However, insoluble fiber may also help with IBS constipation. Discuss your fiber needs with your registered dietitian.
• Probiotic-Rich Foods: Probiotics are considered the “good” bacteria that offer many health benefits, especially for the gut microbiome and those with IBS. Foods like yogurt, kefir, sauerkraut, and kimchi are typically natural sources of probiotics. 
• Herbal Teas and Water: Hydration is a critical component of digestive health. Some beverages, like coffee and caffeinated sodas, act as diuretics, pulling water from your system. However, drinking enough water can help support a healthy GI tract, and some studies have shown that herbal teas may improve GI motility and diversity in the gut microbiota.² 

10 Best Vegetables to Relieve IBS Symptoms

Vegetables are crucial in meeting nutrition needs when designing an IBS-friendly diet. However, not all veggies are created equal, and some may contribute to or exacerbate symptoms of IBS. Starting an IBS diet plan typically involves eating low-FODMAP foods for a pre-determined time. 

Veggies that fit within those guidelines may include:

• Carrots: Carrots can support healthy digestion in those with IBS. They are low in hard-to-digest starches and high in fiber, promoting good digestion and regular bowel movements. They also provide a list of essential nutrients like vitamin A. 
• Cucumbers: Cucumbers, a low-FODMAP vegetable, may benefit those with IBS. Their high water content aids hydration and digestion, and their mild flavor makes them easy to incorporate into various culinary dishes.  
• Squash: Due to its low FODMAP profile and high water content, squash can be a beneficial addition to an IBS-friendly diet. Eating squash may help improve digestion and support bowel regularity without the discomfort that some veggies cause. Squash can be enjoyed steamed, roasted, or in various soups or stews. 
• Turnips: Turnips are a low-FODMAP vegetable with moderate fiber content, making them a favorable pick for those managing IBS symptoms. Turnips are rich in vitamins and minerals, which can support digestion and overall health. Plus, they have an earthy flavor that pairs well with multiple dishes.
• Zucchini: Zucchini is a low-FODMAP food and often a favorite vegetable for the IBS diet. Its high water content supports proper hydration and digestion. Its mild flavor pairs well with a list of culinary cuisines, and it’s packed with other potent nutrients like vitamins C and K. 
• Spinach: Spinach is an excellent choice for those managing IBS symptoms. It is a low-FODMAP veggie rich in essential nutrients like iron and vitamin C.
• Green Beans: Green beans can be an excellent choice for those with IBS as they are low in poorly digested starches and rich in essential nutrients. They’re typically easy to digest and can be included in various recipes. 
• Eggplant: Eggplants are a good vegetable for the IBS diet due to their low FODMAP content. They can be prepared in many different ways and provide a list of essential vitamins, minerals, and antioxidants. 
• Sweet Potatoes: Sweet potatoes are rich in vitamins, fiber, and antioxidants, making them a powerful vegetable for managing inflammation. They’re a low-FODMAP veggie that can be prepared in various ways.
• Bell Peppers: Bell peppers can aid digestion and support bowel regularity. Because they’re a low-FODMAP food, they’re ideal for most IBS diets. They’re also rich in various nutrients like vitamins A and C.

How to Start an IBS Diet

While an IBS diet cannot cure chronic GI, it can help manage symptoms and improve overall quality of life. However, it’s important to remember that you’re not alone in this, and your healthcare team is there to support you. A registered dietitian can help you avoid nutrient deficiencies while navigating new eating patterns.

To start an IBS diet, consider keeping a food diary to help identify trigger foods. Make a note of which foods cause or worsen symptoms like abdominal pain, diarrhea, and bloating. High-FODMAP foods, such as dairy products, gluten-containing products, and spicy foods, are known culprits behind many IBS flare-ups. Once your trigger foods are identified, discuss them with your registered dietitian and develop a plan to eliminate them from your diet gradually.

Then, with the help of your gastroenterology team, transition to a low-FODMAP diet that restricts fermentable carbs known to aggravate IBS symptoms. Prioritize easy-to-digest foods like lean proteins, gluten-free grains, and certain fruits and veggies. Meal planning is a valuable tool for long-term success on an IBS diet. Plan your meals ahead of time to incorporate IBS-friendly foods and prevent food boredom. Keep IBS-friendly ingredients on hand and schedule regular meal times to set yourself up for success.

Best Tips for IBS Symptoms Management

No two bodies are the same so IBS experiences can vary significantly between individuals. Remember that your health and wellness journey is unique to you, and proper IBS management accounts for many factors. Your gastroenterology team, which often includes a registered dietitian nutritionist, will provide you with personalized recommendations regarding your IBS management. 

Consider these tips for managing IBS symptoms under the guidance of your GI team:

• Prioritize foods rich in probiotics, or talk with your doctor about starting a probiotic supplement. 
• Drink enough water to meet your basic hydration needs, accounting for fluid lost from sweat. 
• Practice stress-management techniques, such as therapy, good sleep hygiene, and meditation. 
• Aim for consistent fiber intake.
• Avoid foods known to cause your IBS symptoms, such as Brussels sprouts, cabbage, artichokes, plums, whole-grain cereals, and legumes like lentils and chickpeas. 
• Limit intake of artificial sweeteners, such as xylitol and sorbitol, as they may trigger GI distress. 
• Fructose, found in high levels in high-fructose corn syrup, fruit juice, and dried fruit, may exacerbate IBS symptoms. Opt for fruits lower in fructose, such as blueberries, cantaloupe, and bananas.
• Be mindful of your lactose intake. Lactose-containing foods, such as ice cream, cow’s milk, cheeses, and creams, may cause gas and abdominal pain when eaten in excess. Lactose-free milk products may be an appropriate substitution.
