At the end of the day, 42-year-old Jill would often look down at her stomach in awe that it was distended more than when she was pregnant. The gas, cramping, and irregular bowel movements that would swing between constipation and then diarrhea were negatively influencing her mood and quality of life.

What to eat for IBSIrritable bowel syndrome is a gastrointestinal disorder characterized by any one or all of the following recurring symptoms: constipation, diarrhea, gas, bloating, cramping, or abdominal pain. The cause of irritable bowel syndrome is unknown and thought to be related to changes in the sensitivity of nerves and rate of contractions of the intestines as a result of genetics, gastrointestinal infection, food intolerance, and psychological factors such as stress, anxiety, and depression.

What foods may worsen IBS symptoms?

There is no single nutrition plan that will work for everyone with irritable bowel syndrome. As Jill learned, keeping a food record for a few weeks of her intake and digestive symptoms started to show a few patterns and a few foods that proved to be problematic.

Specific foods do not cause irritable bowel syndrome but the most common foods cited in research that may increase symptoms include fatty foods (such as high-fat snack foods, heavy restaurant meals, fried foods, cream sauces and fatty meats), cauliflower, broccoli, cabbage, brussels sprouts, cabbage, onions, garlic, legumes, whole grains, eggs, nuts, and seeds. Limiting the quantity of high-fat foods eaten at one time as well as eating more of your veggies cooked instead of raw may improve irritable bowel symptoms. Consider an over-the-counter alpha-galactosidase supplement such as Beano to prevent gas that can help break down complex starch found in legumes, vegetables and grains.

Also be aware alcohol, MSG (monosodium glutamate), caffeine, carbonated beverages, and chewing gum may be problematic for some people with irritable bowel syndrome.

Inulin fibre supplements and inulin added to some breads, pastas, crackers, cookies, and yogurts can cause gas and other symptoms.

Sorbitol, mannitol and xylitol are types of sugar alcohols added to low-calorie candy, diet products, and sugar-free sweeteners can cause gas and diarrhea so should be avoided.

Large quantities of fructose (the natural sugar in fruit, juice ,and honey) can aggravate irritable bowel syndrome symptoms so be mindful of portions consumed at one time.

A large percentage of people have a lactose intolerance that hinders their ability to break down lactose (the carbohydrate part of dairy foods such as milk, yogurt and ice cream). If you suspect dairy foods or other foods such as wheat are a problem for you, ask your doctor to screen you for lactose intolerance and celiac disease before unnecessarily removing these foods from your diet.

What foods may improve IBS symptoms?

Firstly, remember that drinking enough fluids is very important for normal healthy digestion. Be sure to drink two to three litres of water or other fluids each day.

Plant based foods such as grains, vegetables, and fruit contain a mix of both insoluble and soluble fibre both needed for health and digestion. If you have irritable bowel syndrome, try increasing soluble fibre in particular. Soluble fibre forms a gel and slows digestion and is found in foods such as breakfast cereal containing psyllium, oatbran, oatmeal, barley, avocado, asparagus, oranges, and pears.

While beans, lentils, and chickpeas contain a high level of soluble fibre these foods are also gas producing so these would need to be tested to see if they are helpful or harmful for your symptoms. When using canned legumes, drain and rinse the liquid they are packed in to help reduce gas.

The 3 P’s of products to take

While there are many supplements on the market, if you are considering taking a supplement to help you manage symptoms, here are three worth considering:

Probiotics: Friendly live bacteria such as bifidobacterium, lactobacillus and acidophilus that live in the gut can help with IBS symptoms and overall health. Probiotics are available in supplements or found naturally in yogurts advertising they contain live bacteria culture.

Psyllium: Psyllium supplements (also found in Metamucil) are a rich source of soluble fibre shown to relieve constipation and improve symptoms such as diarrhea and abdominal pain. Some research shows relief is sometimes not seen for four weeks after starting psyllium supplementation.

Peppermint Oil: Several studies show that taking peppermint oil can reduce abdominal pain, distension, gas, and bowel movements in those with irritable bowel syndrome.

Routine is critical

Your gut likes routine. You may find the more consistent the type, time, and quantity of your food intake, the better. Other consistent lifestyle patterns such as getting enough sleep and quiet time to relax and relieve stress are also key. Regular physical activity is a great stress reliever and can help stimulate bowel movements.

Also, providing a regular, non-rushed time each day to go to the bathroom may sound simple but can be a game-changer in managing irritable bowel syndrome. Jill found that as much as she hated getting up earlier each day, being less rushed before work ensured she could relax and have a bowel movement. Days this was skipped; inevitably she experienced gas, bloating, and difficulty going to the bathroom later that day.

“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. Andrea and her team really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

Event Planner for Laboratory Diagnostic Imaging Annual Event

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”

“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
