Navigating Nutrition for ASD Families can be challenge. If you are a parent, caregiver, or educator supporting an individual with Autism Spectrum Disorder (ASD), you’ve probably come across a wide array of diets and nutrition recommendations. In those early stages of diagnosed children, it’s easy to wonder if the Autism Diet a real thing and googling ‘Foods for Autism’ can take you down a rabbit-hole. One of the most talked about trends in the ASD world for dietary recommendations is the gluten-free, casein-free (GFCF) diet.
But does it actually make a difference for Autistic individuals and their families? With the help of our NDIS Dietitian, let’s find out more about the GFCF Diet.
So, What’s the Hype with the GFCF Diet?
First of all, what is gluten-free, casein-free (GFCF) diet?
Gluten refers to the protein found in wheat, barley, and rye.
Casein refers to the protein found in dairy products like milk, cheese, and yoghurt.
The GFCF diet is an elimination diet. It means cutting these two proteins out of your child’s food intake. The belief is that by removing foods containing these proteins, it can help to reduce autism-related symptoms such as social challenges, repetitive behaviours, or even digestive problems that commonly affects people with ASD.
The justification behind eliminating these proteins comes from researchers who suggested that certain individuals with ASD might have trouble digesting them, thus leading to negative effects on their behaviour. However, in the big picture, the evidence is mixed, and there is no definitive ‘yes’ or ‘no’ answer to the benefits of this diet.
But has the GFCF Diet Worked?
The success of the GFCF diet has been varied. Some parents swear by it, reporting noticeable improvements in behaviour, focus, and even sleep patterns. However, on the flip side, some families report that they don’t see these improvements. Why is that the case?
Up till now, there has yet to be solid scientific consensus that a GFCF diet works for every individual with ASD. It’s a bit like trying a new haircut – some people look great, some just don’t. So, while it may help in some cases, it is definitely not a one-size-fits-all approach.
What are the Benefits Shown of the GFCF Diet?
For some individuals with ASD, cutting out gluten and casein has been beneficial.
Here are a few potential upsides:
Gut Health: Many people with autism experience digestive issues such as constipation, diarrhea, abdominal pain, reflux, and irritable bowel diseases. Some research suggests that the GFCF diet can help reduce these symptoms.
Improved Behaviour: Some parents have noticed fewer meltdowns or aggression, especially if gluten or dairy seems to cause discomfort.
Better Focus: There are reports that removing these foods can improve focus and attention, which makes it easier for children to engage with their environment.
However, these experiences reported by parents are often anecdotal, and what may work for one child may not work for another. It is also important to consider that some of these individuals with ASD may simply have other conditions that need to be diagnosed, such as a food allergy, coeliac disease, or lactose intolerance.
Are There Any Drawbacks of the GFCF Diet?
There are always two sides to a story. Here are some potential downsides to consider before jumping in:
Nutrient Deficiency: Cutting out entire food groups no matter which, will always result in missing out on essential nutrients. For example, eliminating dairy will mean removing an excellent source of calcium and vitamin D from their diet.
Social Challenges: Socially, families implementing these diets can feel more socially isolated when eating out or on holidays as they are limited in their menu options.
Cost and Time: For parents and caregivers, embarking on a GFCF diet can be time- and cost-consuming. There will be increased time spent for food shopping and preparation, and gluten-free products are limited and often more expensive.
But Dr. Google said… Where Exactly Should I get my ASD nutritional info from?
Raise your hand if you’ve ever felt inundated after Googling “foods for autism”, and you find a long list of foods and diets to try and avoid, such as cutting out preservatives, corn, sugar, and processed foods. How much of this is backed by science? Cutting out overly processed foods is generally good advice for everyone, not just specifically linked to ASD.
Much of the information you find online are based on individual experiences, and it is not often that scientific studies are at the top of your search results. The best way to get information and advice is from a professional. Although there are many professionals now specialising in ASD, when it relates to food and nutrition, look for a Dietitian. They are trained to assess nutrition from a scientific standpoint to ensure your diet is nourishing, and also considers your personal situation.
Other ASD Considerations
One fascinating thing about ASD is how sensory sensitivities can influence their eating habits. Dietitians are educated on how people with ASD can have heightened or diminished responses to sights, sounds, smells and textures – especially when it comes to food.
Understanding these sensitivities is key to developing a plan that works with these to create healthier eating habits, making food and mealtime a lot more pleasant for everyone.
Do Dietitians Recommend the GFCF Diet for ASD?
Dietitians generally encourage a balanced and individualised approach. While there’s no strong scientific evidence that a GFCF diet is the gold standard, some families may still want to give it a try.
The takeaway here is that if you are considering implementing the GFCF diet for someone with ASD, it is always a good idea to consult a Dietitian that can help guide you to make sure your child still gets all the nutrients they need for their healthy growth, whilst considering foods that causes sensory challenges or food sensitivities.
The Bottom Line
The GFCF diet has definitely produced some success stories, but it is not the magic solution for everyone. Navigating ASD and dietary routines is incredibly individual and situation-based. The best way to find your way is to seek out a Dietitian that can help you create a plan surrounding the unique needs of the person with Autism.
