What's the difference between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)? ...with Dr Kerith Duncanson

In this episode of Nutrition Science Bites, Professor Clare Collins interviews Dr Kerith Duncanson, a dietitian and researcher in gut health nutrition, to delve into the complexities of gastrointestinal health. They focus on the most common gut conditions, including Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD) and Functional Dyspepsia (FD). They discuss the importance of the diagnostic journey to work out which of these conditions a person has, the gut-brain connection, and the role of diet in managing symptoms.

Dr Kerith emphasises the importance of personalised nutrition and dietary intervention strategies, including appropriate use of FODMAPs, and the current understanding of a 'leaky gut'. The conversation concludes with Dr Kerith sharing a recipe for Cauliflower Steaks, to highlight the importance of incorporating prebiotic-rich foods into the diet.

What is healthy eating?

Eating healthy is making sure you enjoy a wide variety of foods from each of the five major food groups daily, in the amounts recommended. The five major food groups as recommended by the Australian Guide to Healthy Eating are:

  1. vegetables and legumes/bean
  2. fruit
  3. lean meats and poultry, fish, eggs, tofu, nuts and seeds, legumes/beans
  4. grain (cereal) foods, mostly wholegrain and/or high cereal fibre varieties
  5. milk, yoghurt, cheese and/or alternatives, mostly reduced fat.

Foods are grouped together because they provide similar amounts of key nutrients and eating a variety of foods from the list above helps to promote good health and reduce the risk of disease.

Is my diet healthy?

Dietary habits are different between people. Some people choose to follow a particular diet (i.e., Keto diet or vegan diet) while some have to make changes due to certain food restrictions or health conditions. If you want to know if what you usually eat is healthy, then do the Healthy Eating Quiz today to give you the answers in less than 10 minutes.

Why is healthy eating important?

Your HEQ score and personalised feedback report is based on the frequency and variety of healthy core foods you usually eat. This is important because no single food contains all the nutrients we need to stay healthy. Some foods are higher in nutrients than others and people who have a lot of variety in the foods they eat are more likely to be healthy and to stay healthy. In other words, if you can eat a large variety of vegetables as opposed to only 2-3 types of vegetables, the benefits are much greater. This type of diet also helps you to feel better, think better and perform better during your usual daily activities.
