What is BioIndividual Nutrition?

Food and nutrition affect the health, learning and behavior associated with many childhood disorders (and conditions outside of childhood). Because body and brain are connected, you can improve or eliminate symp­toms of autism and ADHD by giving special attention to the food and nutrition children receive.


Each child has unique BioIndividual nutrition needs

However, there is no one-size-fits-all dietary program. Each child has unique biochemical needs and requires a personalized BioIndividual NutritionTM approach.

BioIndividual Nutrition is the science and clinical application of nutrition intervention (food and nutrient choices) based on the individual biochemical needs of the unique person. BioIndividual Nutrition is the synthesis of Julie Matthews’ twelve years of clinical experience and research behind childhood disorders and food and nutrition needs. (Learn more about our Professional Training Course.)

Nourishing Hope® brings together the scientific research and clinical experience to individualize and apply the most supportive food and nutrition plan for each person.

To determine the best diet for a particular individual, you must consider: digestive capacity, bio-individuality, family history, inflammation, symptoms present, and more. The diet that’s best for one person, may not be right for another. Depending on the individual, any of these diets can be healing: Gluten-free casein-free, SCD, GAPS Diet, Paleo, Low oxalate, Body Ecology, Failsafe, Feingold, Low FODMAPS, or another diets.

You will learn which diet (or combination of dietary principles) you or your child needs to heal.

There are many improvements when parents take charge of diet—here are some of the most commonly reported:

  • Better Attention
  • Reduced hyperactivity
  • Improved eye-contact and socialization
  • Improved digestion
  • Reduced constipation and diarrhea
  • Less rash or eczema
  • Physical pain relieved
  • Decreased aggression
  • Language skills increase
  • More calm
  • Sleeping through the night
  • Easier toilet training

Nourishing Hope shares the science underlying childhood disorders, and which foods and nutrients improve symptoms of autism, ADHD, and other childhood disorders.

    Does the book Nourishing Hope explain how we as parents can determine which diet will be more suitable for our children? Or do we need to have a consultation with a biomedical doctor first? How do we know what the biochemical needs are for our children?

    I cannot speak for the book; I’ve just (re-)found this website.

    But, as someone with longstanding gut issues, and Asperger’s, who’s done a LOT of experimentation and research…

    Here’s my personal advice regarding how to approach what type of diet is suitable:

    Medical tests and/or other doctor advice can certainly help.

    Good doctors can help lots.

    However, you need to really be aware of the signs of inflammation or other issues: becoming more anxious when there are gut problems, or more finicky, or whatever.

    It’s likely slightly different for everyone.

    I can TELL when I’ve eaten something bad for me — there’s brain fog (maybe this manifests as functioning less well or clearly in others?)… and often noticeable anxiety and/or agitation.

    This has happened SO many times to me that when I’m anxious or agitated, I look around for: gut irritants and environmental irritatnts (I’m chemically sensitive.)

    (Probably, by the way, all people with ADD, autism, etc. would benefit a lot from living as chem-free as possible, especially with soaps, hair wash, “air freshener” and any other conventional cleaning product or pesticides you can think of.

    Or fresh paint, or other things with tons of VOC’s.

    These things are neurotoxic, and toxic to the human body, even if not everyone reacts extremely acutely.)

    I’ve also done a HUMONGOUS amount of my own research and have a pretty good nose for the whole biochemical interrelated system-thingy. 😉

    And, that’s helped me tremendously in seeing the merits and problems with any specific dietary approach. So, mine is customized to all my individual issues.

    (especially necessary with confirmed mercury toxicity, which means a bunch of normal things don’t work as expected… like eating thiol foods such as garlic/onion… or turmeric supplements. Or ALA supplements.)

    So, in brief:

    You/your child is always shifting. We are shiting biological processes.

    Learn how to monitor the responses to various dietary things, and keep learning. And keep monitoring and adjusting as you/your child changes.

    Educate yourself on why a specific diet is designed to include or exclude those specific things, so you can be on your toes and decide for yourself (at least much better).

    Use a doctor/’professional’/whatever that you feel will really benefit you, if you can find one.

    Take all advice and info with a grain of salt. Know that medical tests and studies and the ideas that we pass along right now, here, on the internet… all have specific errors they’re prone to, and blind spots that none of us will necessarily see.

    And keep learning and testing. 🙂

    Oh, and don’t forget to have fun! And empathize.

    Your “child” is a human being, too. I highly suspect that those on the autism spectrum who are not very communicative, etc. are.

    I recall being very young and having certain activities or foods that made me happier and calmer than others.

    And, just like you, when I have certain foods that are meaningful or nice to me, it can affect my stress levels and emotion over a much longer period of time.

    I suspect that when dealing with someone who has leaky gut/gut problems — and thus very likely anxiety by definition — this emotional aspect of stress and being in touch with the emotional reactions to food is really important, too.

    That all said, I don’t know what’s in the book at all. 🙂

    Processed-/prepared-food-free, gluten-free/grain-free, and dairy-free (apart from grass-fed camel’s milk, which is quite different chemically?) seems pretty much a must of any diet for this spectrum.

    And, the cleaner the food, the better.

    Grass-fed, wild, organic, etc.

  3. Xin says:

    Also, while others are often very very very helpful in our journey:

    Be aware that a doctor (or any professional, at anything) is a human being with a slightly different skillset and level in that skill set.

    And that what ANYONE has to offer you at any point in time will just be the best that they know about — but not by any means the literal optimal diet.

    Or even the optimal diet/approach from all the information we already currently have access to.

    There are always more layers of things impacting our health.

    Beyond FODMAPS, salicates, sulfur-high foods, histamines, amines, thiols, insoluble fiber, soluble fiber, nightshades, glycoalkaloids, phytoestrogens, and metal poisoning, insulin issues, adrenal issues all uniquely affecting frequency and types of foods that are most suitable… 🙂

    For small example, he/she will likely not be aware of all the ramifications of a specific test result.

    And no one is fully aware of everything relevant.

    And, not everything relevant is tested for, or efficient to test fo.

    This is another reason to do your own research.

    “How to know what to eat, personally,” is a big, evolving topic, and it will continue to evolve for a verrrry long time.

    Keep learning!

    And, best to everyone reading this!

    Oh, and in case it wasn’t clear: we’re always shifting biological processes, so perhaps the best advice I can give is to be on your toes and ready to shift your diet in accordance to that.

    The best diet you can find is not necessarily going to always be the same thing as the days and months and years pass.

    Hi Julie,

    My daughter is 8 years old and was diagnosed with Rheumatoid Arthritis at age of 1.6. She was in remission for 5 1/2 years through dietary changes and homeopathy. Last year she contracted a parasite that wrecked havoc through her gut, and eventually led to the arthritic symptoms to return. We have been trying to rebuild the gut ecosystem for a while now and it is proving very difficult as stomach aches and loose stools persist. I would like to schedule an appt for personalized nutrition help, if possible.
