Ibs Diet: What To Eat And Avoid

is there a diet to follow for ibs

Irritable Bowel Syndrome (IBS) is a gastrointestinal disorder that affects 1 in 10 people in the United States each year. While there is no one-size-fits-all diet for managing IBS, certain nutritional and lifestyle strategies can help control and improve gut symptoms and quality of life. Doctors may recommend a low FODMAP diet, which eliminates certain poorly absorbed short-chain carbohydrates that can cause intestinal distress. Additionally, increasing fiber intake, staying hydrated, and regular physical activity can help reduce IBS symptoms. It is important to consult with a healthcare professional before making any dietary changes, as restrictive diets can lead to nutritional deficiencies and disordered eating.

Characteristics and Values

Characteristics Values
Diet Type Low FODMAP
FODMAPs Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols
Foods to Avoid Wheat, onions, garlic, barley, cabbage, broccoli, fruit, honey, legumes, beans, etc.
Foods to Consume Non-whole grain foods, non-dairy products
Other Recommendations Increase fluid intake, exercise, consider probiotics

The low-FODMAP diet

  • Fructans (found in wheat, onions, garlic, barley, cabbage, and broccoli)
  • Fructose (found in fruit, honey, and high-fructose corn syrup)
  • Galacto-oligosaccharides (found in legumes and beans)

It is important to consult a doctor or dietitian when considering the low-FODMAP diet, as it can be challenging and may lead to nutritional deficiencies. Additionally, individual triggers may vary, and a professional can guide the process to ensure it is done correctly. While the low-FODMAP diet has shown potential in helping people with IBS, some health professionals believe it is too restrictive. It is always recommended to work with a healthcare provider to find an individualized approach that considers both medical treatment and dietary strategies to effectively manage IBS symptoms.

Gluten-free diet

A gluten-free diet may help alleviate IBS symptoms. Gluten is a protein found in wheat, barley, and rye. Many common foods contain gluten, including most cereal, grains, and pasta, as well as many processed foods. Some people with IBS experience more symptoms after eating gluten, even if they do not have celiac disease.

When following a gluten-free diet, it is important to always check food labels, as gluten may be present in unexpected foods. Foods that may contain gluten include flavoured coffee drinks, malted milk, tea made with malted barley, some forms of dairy, processed soups, and certain types of alcohol made from grains, such as beer, gin, and whiskey.

It is important to note that there is significant disagreement in the scientific community about whether gluten plays a role in IBS. In addition, gluten-free diets may be low in nutrients common in wheat-containing foods, such as folic acid, iron, fibre, and other vitamins and minerals. Nutritional deficiencies can occur, especially during pregnancy when nutritional demands increase. Therefore, it is important to work with a healthcare provider when changing your diet to ensure you are getting adequate nutrition.

In addition to a gluten-free diet, there are other dietary and lifestyle changes that may help manage IBS symptoms. These include increasing fluid intake, reducing high-fibre foods, and trying a low FODMAP diet, which has been shown to be effective in reducing symptoms in up to 86% of people with IBS. However, the low FODMAP diet is very restrictive, and it is recommended to work with a doctor or dietitian to ensure it is followed correctly and to prevent unnecessary food restrictions.

Nutritional deficiencies

A systematic review found that the usual diets of IBS patients were significantly low in vitamins B1, B2, B6, B9, calcium, iron, magnesium, and zinc when compared to recommended intakes. When compared to healthy individuals, IBS patients were also found to have reduced consumption of vitamin A, B2, B9, B12, calcium, and zinc.

The low FODMAP diet, which is often recommended for managing IBS symptoms, can be restrictive and may contribute to nutritional deficiencies if not properly managed. The diet eliminates certain carbohydrates that are hard to digest, including some fruits, vegetables, and grains. While this can help reduce IBS symptoms, it can also reduce the intake of important nutrients. Therefore, it is crucial to work with a trained dietitian when following this diet to ensure adequate micronutrient consumption and to learn when to reintroduce trigger foods.

Additionally, IBS patients are often advised to increase their fibre intake, as it can help with constipation by softening stools and making them easier to pass. However, too much fibre, especially if introduced too quickly, can cause gas and bloating, which can trigger IBS symptoms. Thus, it is important to gradually increase fibre intake and choose high-fibre foods that are also rich in micronutrients to avoid potential deficiencies.

Overall, dietary support from a trained dietitian is essential for IBS patients to manage their symptoms and achieve nutritional adequacy, preventing potential health complications from micronutrient deficiencies.

Lifestyle strategies

While there is no single diet or medicine that works for everyone with IBS, there are several lifestyle strategies that can help improve your symptoms and overall quality of life. Here are some strategies to consider:

Consult a healthcare professional

Before making any dietary changes, it is important to consult your doctor, a dietitian, or a specialist. They can provide personalized advice and recommend treatments to help manage your IBS symptoms. A registered dietitian can guide and support you in creating a long-term food plan that works for your lifestyle.

Try the low FODMAP diet

FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are short-chain carbohydrates that are poorly absorbed by the small intestine and can cause intestinal distress. The low FODMAP diet is a temporary, restrictive eating plan that helps identify which foods trigger your IBS symptoms. It is recommended to try this diet for a few weeks to see if it improves your symptoms. If it does, you can slowly reintroduce high-FODMAP foods one at a time to assess your tolerance.

Increase fiber intake gradually

While fiber can help relieve constipation in IBS, it's important to increase your fiber intake gradually. Add foods with fiber to your diet a little at a time to prevent gas and bloating, which can trigger IBS symptoms. Aim for an increase of 2 to 3 grams of fiber per day.

Stay hydrated

Drinking enough fluids is important for managing IBS symptoms. Aim for 8 to 10 drinks of fluid per day, such as water or herbal tea, totaling around 1.5 litres.

Engage in regular physical activity

Physical activity can help reduce gas, bloating, stress, and anxiety, all of which can trigger gut symptoms. Consult a healthcare professional to determine the appropriate level of physical activity for your condition.

Consider probiotics

After consulting your healthcare provider, you may want to try incorporating a daily probiotic into your routine for at least one month to monitor its effects on your symptoms.

Remember, the relationship between food and IBS is complex, and individual triggers can vary. It is essential to work with a healthcare professional to develop a personalized plan that considers your specific needs and lifestyle.

Physical activity

While there is no cure for IBS, physical activity can be a great way to help manage the symptoms. Research has shown that people with IBS who increase their physical activity levels tend to have better overall health and improved IBS symptom management.

It is important to note that not all forms of exercise are suitable for people with IBS. High-impact exercises with abrupt or lurching motions, such as CrossFit, long-distance running, and ball sports, can potentially upset the gastrointestinal system and worsen symptoms. Instead, low- to moderate-intensity exercises are recommended for people with IBS.

Walking is a great, easily accessible form of exercise for people with IBS. Swimming is another good option as it rarely leads to cramping or urgent diarrhea. Yoga has also been shown to be effective in improving digestion, reducing IBS symptoms, and improving strength. Other recommended exercises include cycling, light jogging, and tai chi.

It is always a good idea to consult a doctor before starting a new exercise routine, especially if abdominal pain, IBS symptoms, or gastrointestinal distress have prevented you from exercising for an extended period.
