Diet interventions: mechanisms and evidence

Autism content is not the same thing as autism science.

In this episode, Dr. Theresa Lyons joins me to talk about what it really means to follow the science of autism, and why parents cannot rely on headlines, algorithms, or outdated assumptions when the stakes are this high. Theresa is a Yale trained scientist and autism parent, and she breaks down how peer reviewed research actually moves, how easily it gets distorted, and why it can take 20 to 30 years for scientific conclusions to become common medical practice.

We talk about how misinformation spreads online, including research showing that 70% of the most viewed autism videos on TikTok were classified as wrong or over generalized. Theresa explains why credibility does not come from views, and why parents need to get closer to the source, or choose trusted interpreters who do.

We also dig into the bigger picture that often gets missed when families are only offered behavioral therapies. Theresa shares how she thinks about risk, genetics, environment, and total load on the body, and why broad buckets like sleep, diet, hydration, and gut health matter when you are trying to support a child.

This is a powerful reminder to trust your intuition, be willing to do the work, and stay curious. The goal is not to chase every rabbit hole. The goal is to build clarity, prioritize what matters, and change the trajectory one step at a time.

Key Takeaways

• "Follow the science" should mean peer reviewed publications, not headlines. Theresa explains why going to sources like PubMed, or using trusted interpreters of that research, matters when mainstream summaries can be rushed, incomplete, or wrong.
• It can take 20 to 30 years for research to reach common practice. That lag matters when your child is five now, not thirty five later, and it is why parents often need to be proactive rather than waiting for systems to catch up.
• Mainstream media can sound credible while still being misinformation. Theresa shares how even well meaning articles can be based on shallow research done under deadline pressure, which can derail a family's decisions if they are not careful.
• Online engagement is not the same thing as accuracy. Research discussed in this episode found that 70% of top autism videos on TikTok were classified as wrong or over generalized, which is a wake up call about where many families are getting "education."
• Parents have to balance curiosity with discernment. The goal is not to chase everything. The goal is to build enough scientific literacy to ask better questions, recognize weak claims, and avoid fruitless rabbit holes.
• Autism is diagnosed through observation, which can hide the "why" underneath. Theresa explains how biology, chemistry, and health factors can be missed until developmental delays become obvious, and then families are left sorting out root contributors after the fact.
• Broad health buckets deserve attention alongside therapies. Sleep, hydration, digestion, and diet can meaningfully affect regulation and behavior, and Theresa points out that these basics are often dismissed as "just autism" when they deserve real investigation.
• Diet interventions require clarity about goals and consistency. Theresa discusses why families need to identify symptoms first, understand mechanisms like gut permeability and immune load, and avoid comparing "partial" changes to results from structured clinical trials.
• Risk is complex because genetics and environment interact. Theresa describes why research often speaks in terms of increased risk rather than simple causation, and why what is relevant depends on the individual child's context.
• Trust your intuition and commit to the long game. Theresa's closing message is that change is like turning a boat. It takes effort and time, but a parent's willingness to learn and keep going can meaningfully change a child's trajectory.

About Theresa Lyons

Dr. Theresa Lyons is an international autism educator, Ivy League scientist, and autism parent. She holds a PhD in computational chemistry from Yale University and previously worked in the pharmaceutical industry in research and development and as a medical strategist. After her daughter was diagnosed with autism, she applied her scientific training to understanding autism research and now teaches parents how to navigate the science with clarity and confidence. She is the founder of Navigating AWEtism, a platform designed to turn autism complexity into clarity by organizing scientific information and making it accessible and actionable for families. Through her work, she has supported parents in 21 plus countries and reaches a growing global audience through years of science backed education on YouTube and social media.
