Nature's Answer to Autism: The Broccoli Compound Challenging Medical Dogma

What if the key to improving autism symptoms by addressing one of the major root causes was hiding in your vegetable drawer all along?

For years, the National Autistic Society (NAS) and many mainstream medical organizations have maintained that there are no effective treatments for the core symptoms of autism spectrum disorder (ASD) - while at the same time claiming there is no evidence linking vaccines to the the condition. However, a growing body of scientific research is not just challenging the view that autism causes and cures are unknown or unknowable - it’s shattering it. Emerging studies demonstrate that certain natural, non-patentable approaches can lead to significant improvements in individuals with ASD, offering hope to millions of families worldwide. In fact, you can use the GreenMedInfo.com autism research resource, which includes evidence on over 100 natural approaches (including studies linking vaccines and vaccine components to the autism epidemic), all which are viewable here.

One particularly promising area of research involves sulforaphane (view 11 studies here), a compound found in cruciferous vegetables like broccoli. A groundbreaking 2014 study published in the Proceedings of the National Academy of Sciences USA titled “Sulforaphane treatment of autism spectrum disorder (ASD)” provides compelling evidence that contradicts the NAS stance.¹

This placebo-controlled, randomized pilot study involved 44 males with ASD, aged 13-27. After 18 weeks of treatment with a sulforaphane-rich broccoli sprout extract:

• 46% of participants showed significant improvements in social interactions

• 42% demonstrated significant improvements in verbal communication

• Over half the participants exhibited decreases in abnormal behaviors, including irritability, hyperactivity, and repetitive movements

These results directly challenge the assertion that there are no treatments for core ASD symptoms. Importantly, sulforaphane is a natural compound, not a patented pharmaceutical, making it an accessible and potentially affordable option for many families.

The researchers selected sulforaphane based on its well-characterized physiological effects, which address many of the underlying issues associated with ASD:

• Reducing oxidative stress and improving antioxidant capacity

• Enhancing glutathione synthesis

• Improving mitochondrial function and oxidative phosphorylation

• Decreasing lipid peroxidation

• Reducing neuroinflammation

This multi-faceted approach to addressing ASD’s root causes may explain its effectiveness compared to more narrowly targeted pharmaceutical interventions.

It’s worth repeating that sulforaphane is just one of many natural substances showing promise in ASD treatment. The GreenMedInfo.com database not only has indexed research from the National Library of Medicine on over 100 natural substances that may play a role in improving ASD symptoms, but includes a problem substance index (things to avoid or detoxify), as well as therapeutic modality one as well.² In total, this includes dozens of safe, effective, affordable, and easily available various interventions which get almost no mainstream attention versus pharmaceutical approaches, which only address symptoms at best, sometimes causing side effects that exacerbate behavioral issues, and contribute to worsening health outcomes.

For instance, studies have shown potential benefits from:

• Omega-3 fatty acid supplementation³

• Vitamin D supplementation⁴

• Probiotics and gut health interventions⁵

• Gluten-free, casein-free diets⁶

The fact that such research exists and continues to produce positive results raises important questions about why organizations like the NAS maintain there are no effective treatments for ASD. Some possible explanations include:

1. Bias towards pharmaceutical solutions: Many mainstream medical organizations have close ties to the pharmaceutical industry, which may influence their perspective on non-patentable treatments.⁷

2. Resistance to paradigm shifts: The idea that ASD is purely genetic and untreatable has become deeply ingrained in many medical circles, making it difficult to accept contradictory evidence.

3. Lack of large-scale studies: While promising, many studies on natural interventions for ASD have been relatively small. However, this highlights the need for more research rather than dismissing existing findings.

4. Focus on complete “cures” rather than improvements: While natural interventions may not completely eliminate all ASD symptoms, significant improvements in quality of life should not be discounted.

The sulforaphane study and others like it demonstrate that evidence-based, natural approaches to treating ASD do exist, contrary to the NAS’s claims. These findings underscore the importance of keeping an open mind and continuing to explore all potential avenues for improving the lives of individuals with ASD.

For families affected by ASD, this research offers hope and potential new options to explore under the guidance of healthcare professionals. It also serves as a reminder that conventional wisdom in medicine should always be open to challenge and revision based on emerging scientific evidence.

As we move forward, it’s crucial that organizations like the NAS and other autism advocacy groups remain open to new research and are willing to update their positions based on the best available evidence. Only by doing so can we ensure that individuals with ASD have access to all potentially beneficial treatments, whether they come from pharmaceutical labs or nature’s pharmacy.

The sulforaphane study’s lead researcher, Dr. Andrew Zimmerman, put it best:

“We believe that this may be preliminary evidence for the first treatment for autism that improves symptoms by apparently correcting some of the underlying cellular problems.”⁸

It’s time for the medical community to embrace these findings and work towards a more holistic, integrative approach to autism care.
