The Role of Probiotics in IBS Management

What Are Probiotics?
Probiotics are live microorganisms, often referred to as “good” bacteria, that provide health benefits when consumed in adequate amounts. These beneficial bacteria help maintain a healthy balance in the gut microbiome, which is crucial for digestive health. Probiotics have been shown to alleviate symptoms of IBS by improving gut motility, reducing inflammation, and enhancing the gut barrier function [1].
What is Kefir?
Kefir, a fermented milk drink, is rich in probiotics and has gained popularity for its potential health benefits. It is made by adding kefir grains (a combination of bacteria and yeast) to milk or a non-dairy alternative. The mixture is left to ferment at room temperature for about 24 hours,
Should You Drink Kefir if You Have IBS?
For individuals with IBS, kefir can be both beneficial and challenging.
Pros:
- High Probiotic Content: Kefir contains a diverse range of probiotic strains that can help restore gut flora balance [2].
- Digestive Aid: The fermentation process breaks down lactose, making kefir easier to digest for those who are lactose intolerant, a common issue among IBS sufferers [3].
- Anti-Inflammatory Properties: Kefir has been shown to reduce inflammation in the gut, which can alleviate IBS symptoms [4].
Cons:
- Potential for Symptom Flare-Ups: Some individuals with IBS may experience increased gas and bloating when first introducing kefir due to its probiotic content [5].
- Individual Variability: The effects of kefir can vary from person to person, and some may not tolerate it well [6].
Is Kefir Good for Bowel Problems?
Kefir can positively impact bowel health by promoting regular bowel movements and reducing constipation, a common issue in IBS. Studies have shown that the probiotics in kefir can improve stool consistency and frequency, providing relief for IBS sufferers [7]. Additionally, kefir’s ability to enhance the gut microbiota diversity is associated with improved digestive function [8].
Is Kefir Good for an Inflamed Stomach?

The anti-inflammatory properties of kefir can be particularly beneficial for an inflamed stomach. Kefir contains bioactive peptides and other compounds that have been shown to reduce inflammation in the gastrointestinal tract [9]. This can help alleviate pain and discomfort associated with IBS-related inflammation.
Additional Kefir-Specific Questions
- How Much Kefir Should You Drink Daily? For general health benefits, consuming about 1 cup (240ml) of kefir per day is recommended. However, it’s important to start with smaller amounts, especially for those with IBS, to assess tolerance.
- Can Kefir Be Used in Cooking? Yes, kefir can be used as a substitute for yogurt, buttermilk, or sour cream in various recipes, including smoothies, salad dressings, marinades, and baked goods. Heating kefir can kill some of the beneficial bacteria, so it’s best used in cold or room-temperature dishes to maintain its probiotic benefits.
during which the microorganisms break down lactose and produce beneficial compounds.
What Does Kefir Taste Like?
Kefir has a tart and tangy flavour, similar to a slightly sour yogurt. The taste can vary depending on the fermentation process and the specific strains of bacteria and yeast used. Some people describe it as effervescent due to the natural carbonation that occurs during fermentation.
What Forms and Flavours Are Available?

Kefir is available in various forms and flavours to suit different preferences:
- Plain Kefir: The traditional form, usually unsweetened and with the natural tangy taste.
- Flavoured Kefir: Many brands offer kefir in various flavours, such as strawberry, blueberry, vanilla, and mango, often with added natural sweeteners or fruit purees.
- Non-Dairy Kefir: For those who are lactose intolerant or prefer plant-based options, non-dairy kefir made from coconut milk, almond milk, or soy milk is available.
- Kefir Water: A non-dairy alternative made from fermenting sugary water with kefir grains, often flavoured with fruits or herbs. You can learn more about kefir water here.
What is the Price Range for Kefir Compared with Other Similar Products?
The price of kefir can vary depending on the brand, type, and region, but generally, it falls within the following ranges:
- Standard Dairy Kefir: Approximately £1.50 to £3.00 per 500ml bottle.
- Flavoured Dairy Kefir: Around £2.00 to £4.00 per 500ml bottle.
- Non-Dairy Kefir: Usually between £2.50 and £4.50 per 500ml bottle.
- Kefir Water: Typically ranges from £2.00 to £4.00 per 500ml bottle.
In comparison to similar probiotic products like yogurt or kombucha, kefir is often priced similarly but can be slightly more expensive due to its potent probiotic content.
Choosing the Right Probiotic

What is the Best Probiotic if You Have IBS?
When selecting a probiotic for managing IBS, several factors should be considered to ensure effectiveness and suitability.
Factors to Consider When Choosing a Probiotic
Firstly, the strain specificity is key. Different probiotic strains have varying effects on the gut. For IBS, strains such as Lactobacillus plantarum, Bifidobacterium infantis, and Saccharomyces boulardii have been shown to be particularly beneficial [10][11]. Additionally, the Colony Forming Units (CFUs) count indicates the number of viable bacteria in a probiotic. A higher CFU count, generally between 10 billion to 100 billion CFUs, is recommended for managing IBS symptoms [12].
The delivery method of probiotics also matters. Probiotics are available in various forms, including capsules, powders, and liquids. Kefir naturally contains a diverse range of probiotic strains and is a convenient way to consume probiotics daily [13]. But, quality and shelf stability are important; choose products from reputable brands that guarantee the survival of probiotics through the digestive tract. Many kefir products are well-regarded for maintaining probiotic potency due to their fermentation process [14].
Recommended Strains and Products
- Lactobacillus plantarum: Known for its ability to reduce bloating and abdominal pain in IBS patients [10]. This strain is commonly found in both probiotic supplements and fermented foods like kefir.
- Bifidobacterium infantis: This strain helps alleviate overall IBS symptoms, including bowel movement irregularities and inflammation [11]. It is available in supplements and some dairy kefir products.
- Saccharomyces boulardii: A yeast probiotic effective in reducing diarrhoea and stabilising the gut environment [12]. While not typically found in kefir, it can be taken alongside kefir for a comprehensive probiotic regimen.
How to Incorporate Probiotics into Your Diet with IBS

Incorporating probiotics into your daily routine can significantly impact gut health and manage IBS symptoms. Here are some practical tips:
Daily Routines
Start your day with a serving of kefir, which can be added to smoothies or consumed plain. Including probiotic-rich foods in your meals, such as yogurt, sauerkraut, kimchi, and kefir, can also help. Opt for probiotic snacks such as kefir smoothies or probiotic bars to maintain a consistent intake. Regular consumption is key; a daily intake of kefir or other probiotic foods can help maintain a balanced gut microbiome.
Probiotic-Rich Foods and Supplements
Kefir is a versatile probiotic-rich food that can be consumed plain, added to recipes, or used in dressings and marinades. Its high probiotic content makes it an excellent choice for daily consumption. Yogurt is another accessible source of probiotics, offering various strains that support gut health. However, kefir generally contains a broader spectrum of beneficial bacteria [13].
Fermented vegetables, such as sauerkraut, kimchi, and pickles, are excellent sources of probiotics and can complement kefir in providing a diverse probiotic intake. For those who may not consume enough probiotic-rich foods, high-quality probiotic supplements with specific strains beneficial for IBS can be useful.
The Importance of Nutrition in IBS Management

Dietary Guidelines for IBS
Managing IBS often means making thoughtful dietary choices. Certain foods can trigger symptoms, so it’s important to know what to avoid and what to include in your diet.
Foods to Avoid
High-FODMAP foods are common culprits for IBS sufferers. These are fermentable carbohydrates that can cause bloating, gas, and diarrhoea. Examples include certain fruits like apples and pears, vegetables like onions and garlic, and legumes. Dairy products can also be problematic, especially if you’re lactose intolerant. However, kefir is often well-tolerated due to its lower lactose content and beneficial probiotics. Additionally, some people with IBS might find relief by avoiding gluten, found in wheat, barley, and rye. Lastly, fried and fatty foods can slow down digestion and exacerbate symptoms like cramping and diarrhoea.
Beneficial Foods and Meal Planning
Incorporating beneficial foods into your diet can help manage IBS symptoms. Opt for low-FODMAP fruits and vegetables, such as bananas, blueberries, carrots, and spinach. Lean proteins like chicken, turkey, and fish are generally well-tolerated and provide essential nutrients without triggering IBS symptoms. Whole grains such as quinoa, oats, and brown rice can provide fibre without causing irritation. Probiotic-rich foods, including kefir, can help balance gut bacteria and improve digestive health. You can enjoy kefir plain, in smoothies, or as part of meals like overnight oats or salad dressings.
When planning meals, focus on low-FODMAP ingredients to avoid triggers. Incorporate small, frequent meals to avoid overloading your digestive system. Keeping a food diary can also help track which foods cause symptoms, allowing you to adjust your diet accordingly.
The Role of a Nutritionist in Managing IBS
A nutritionist, particularly one specialising in functional medicine, can be a valuable ally in managing IBS. They can assess your individual needs, conducting a thorough review of your dietary habits, lifestyle, and IBS symptoms to create a tailored nutrition plan. Education on food choices is another crucial role of a nutritionist. They can provide guidance on which foods to avoid and which to include, considering your personal triggers and preferences.
Regular follow-ups with a nutritionist can help monitor your progress and adjust your diet as needed, ensuring it continues to meet your health goals. Personalised nutrition plans offer targeted symptom relief by identifying and avoiding specific triggers, significantly reducing IBS symptoms. These plans ensure a balanced diet that meets your nutritional needs without exacerbating IBS symptoms, promoting long-term digestive health and overall well being. If you follow a tailored plan, you’re more likely to stick with it, making sustainable dietary changes that benefit your health in the long run.
Incorporating kefir into your diet as recommended by a nutritionist can further enhance these benefits. Its probiotic content can help balance your gut bacteria, improving your digestive health and potentially alleviating IBS symptoms. Whether you drink it plain, add it to smoothies, or use it in recipes, kefir can be a versatile and tasty addition to your IBS management plan.
Lifestyle Changes for Better Well Being

Stress Management Techniques
Managing stress is beneficial for improving IBS symptoms and overall well being. Stress can significantly impact IBS, often exacerbating symptoms such as abdominal pain and irregular bowel movements. Incorporating mindfulness and relaxation exercises into your daily routine can be highly beneficial. Techniques like deep breathing, meditation, and progressive muscle relaxation can help reduce stress levels and promote a sense of calm. Practising mindfulness, which involves staying present in the moment, can also help manage stress and reduce IBS symptoms.
Working with a nutritionist can further enhance stress management strategies. At IBS Clinics, our nutritionists provide personalised advice on diet and lifestyle changes that can help reduce stress and improve gut health. By addressing your specific needs, we can help you develop effective coping strategies to manage stress and its impact on IBS.
Physical Activity and IBS
Physical activity plays a significant role in managing IBS and promoting overall health. Engaging in appropriate exercises can help improve digestion, reduce stress, and boost energy levels. Low-impact exercises such as walking, swimming, and yoga are particularly beneficial for individuals with IBS. These activities can help stimulate bowel movements, reduce bloating, and improve overall gut function without causing undue strain on the body.
It’s important to stay active without aggravating IBS symptoms. Here are some tips to help you get started:
- Start Slowly: Begin with gentle exercises and gradually increase the intensity and duration as your fitness improves.
- Listen to Your Body: Pay attention to how your body responds to different activities. If you experience discomfort, adjust your routine accordingly.
- Stay Hydrated: Drink plenty of water before, during, and after exercise to stay hydrated and support digestion.
At IBS Clinics, we recognise that physical activity is an essential component of a holistic approach to health. Our nutritionists can help you develop a personalised exercise plan that suits your needs and supports your overall well being.
