New info on what to eat if you struggle with Irritable Bowel Syndrome

If you have IBS (irritable bowel syndrome) and are experiencing digestive symptoms such as constipation, diarrhea, abdominal cramping or gas you are not alone.

You may have heard about some of the new research being done on what is known as the FODMAP diet as a potential treatment for IBS (irritable bowel syndrome).Spinach

Although research is still limited, data from several short-term (less than 6 week) clinical trials suggest that a low FODMAP diet can reduce uncomfortable digestive symptoms such as abdominal pain, bloating and excessive gas in up to 75 per cent of individuals with IBS.

What are FODMAPs?

FODMAP stands for Fermentable Oligosaccharides Disaccharides Monosaccharide Polyols. FODMAPs are certain types of sugars and fibres that are found in many common foods such as fruits, vegetables, legumes, grains, milk products and sweetening agents.

Oligosaccharides: short chain fibres such as fructans, galacto-oligosaccharides and inulin found in foods such as wheat, rye, certain vegetables, certain fruits, dried peas/beans, nuts/seeds and chicory root.

Disaccharides: two single carbohydrate sugars linked together. Most important to consider is lactose found in dairy foods such as milk, yogurt, ice cream and some cheese.

Monosaccharides: single carbohydrate units. The most important to consider is excessive fructose found in fruit juice, honey, agave, high-fructose corn syrup, sugar and large volumes of fruit.

Polyols: sugar alcohols found in certain fruits and vegetables as well as in certain sugar-free and diet foods containing sorbitol, mannitol, xylitol, maltitol and isomalt.

It should be noted that most people can eat FODMAPs without any digestive issues and following a low FODMAP diet is unnecessary.

However some individuals with sensitive digestive systems or with IBS can experience less digestive symptoms by following a low FODMAP diet. This is because for some people FODMAPs may be poorly absorbed in the quinoasmall intestine and when they travel to the large intestine they can draw water. Also in the large intestine, fermentation (digestion) occurs by bacteria that live naturally in the gut that can create gas and other byproducts. Research has established there are individual differences in tolerance for FODMAPs with some foods causing more symptoms than others.

What does a low FODMAP diet look like?

Partial list of high FODMAP foods to limit:

  • Regular milk, yogurt, cottage cheese, ricotta cheese, ice cream and soy milk
  • Apricots, apples, blackberries, dried fruit, cherries, fruit juice, nectarines, pears, peaches, plums, mango, watermelon
  • Asparagus, avocado, beets, Brussels sprouts, cauliflower, celery, garlic, mushrooms, onions, peas and tomato paste
  • Wheat, barley, rye (as well as cereals, pastas, bars or baked goods made of these items)
  • Sugar-free candy and gum; honey and high fructose corn syrup
  • Baked beans, refried beans, chickpeas, kidney beans, edamame and hummus
  • Pistachios, cashews

Partial list of low FODMAP foods to enjoy:

  • Lactose-free dairy foods or certain hard cheese like cheddar, Parmesan, Swiss and mozzarella
  • Strawberries, blueberries, banana, cantaloupe, grapes, honeydew, kiwi and oranges
  • Bell peppers, carrots, chives, cucumber, kale, lettuce, grapefruit, raspberries, spinach, fresh tomatoes, scallion greens, white potatoes and zucchinifruit salad
  • Cornmeal, quinoa, rice and spelt (as well as cereals, pastas, crackers or baked goods made of these items)
  • Meat, poultry, eggs, seafood, firm tofu as well as small handfuls of nuts such as peanuts, pumpkin seeds and sunflower seeds

Where should I begin?

If you are experiencing digestive issues it is essential to visit your physician to have a proper medical assessment to be sure the diagnosis and treatment is correct. If your physician has diagnosed you with a functional bowel disorder such as IBS, work with a Registered Dietitian, the only university trained and regulated nutrition professional. A dietitian that specializes in nutrition for IBS can first help you understand the overall nutrition and lifestyle strategies important for IBS and other digestive issues.

Then if the traditional lifestyle and nutrition recommendations have not provided relief of uncomfortable symptoms, your dietitian can help you explore the low FODMAP diet. Since this is a complicated and restrictive diet to follow, your dietitian can help ensure you are getting enough good nutrition. Since this diet is not meant for the long-term, dietitian support can help you understand the re-introduction phase of individual foods to assess your personal tolerance.

Adele Fox, Psychologist
“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. They 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.”

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.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“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!”
