Sayer Ji, FounderFor decades it was believed that brain regeneration was not possible. But an accumulating body of research now reveals that common foods such as broccoli contain compounds capable of stimulating the repair and renewal of nerve tissue.
Ever since Santiago Ramón y Cajal, the father of
neuroscience, declared “nothing may be regenerated” in the adult brain,
the idea that you can repair or regenerate damaged brain tissue was
precluded by this central dogma. But compelling evidence for brain
regeneration began to surface in the 1960’s with a report by MIT
scientist Joseph Altman that the hippocampus of adult rats and guinea
pigs and the cortex of cats indeed underwent a process termed
neurogenesis,1 i.e. the growth and development of nervous tissue.
In the decades that followed, more and more evidence began
to amass showing the brain is in a continually dynamic state of
self-repair and self-regeneration, relying on neural stem cells to
replace and repair damaged and aged tissue. Clearly, in an era of
widespread neurodegenerative disease which the conventional medical establishment claims are incurable,
this discovery is encouraging. If the brain can regenerate, the the key
is to find out how to prevent interference with this process and/or
ascertain methods to increase and support its innate self-healing
capacity.
In a previous report, we looked at research on a compound
found in turmeric known as aromatic-tumerone. This fat soluble component
appears to be an ideal candidate for enhancing the brain’s natural
regenerative process. Learn more by reading How WHOLE Turmeric Heals The Damaged Brain.
But this is just scratching the surface. We have indexed
over 45 natural substances with putative neuritogenic properties which
can be viewed here: Pharmacological Action: Neuritogenic.
The newest addition to this list is sulforophane, an
incredibly powerful sulfur-containing biomolecule found in cruciferous
vegetables. Our sulforophane database
contains research on its potential therapeutic value in about 200
different conditions. You can read our recent review on this amazing
healing food component here: Top 10 Reasons to Eat Your Cruciferous Veggies.
Now, a new study published in the journal Genesis entitled, “Effects of sulforaphane on neural stem cell proliferation and differentiation,”
reveals that sulforaphane may have significant ameliorative properties
against the underlying pathological disturbances found in common
neurodegenerative diseases such as increased oxidative stress,
inflammation, perturbed calcium homeostasis, and neuronal death. The
authors of the study theorized that sulforaphane may mitigate these
factors, along with stimulating neural stem cells (NSC) activity. An
already robust body of literature exists indicating that sulforaphane
has the following beneficial pharmacological actions:
-
Up-regulation of nuclear factor erythroid 2-related factor 2 (Nrf2), which increases innate antioxidant mechanisms.
-
Suppressing of interleukin-1b (IL-1b), to exert its anti-inflammatory effects.
In contradistinction, the new study sought to evaluate if
sulforphane is capable of protecting, and regulating neural stem cells
in such a way as to confer neuroprotective properties. It also sought to
determine if sulforophane’s therapeutic properties depend in some way
on its Wnt signaling properties, which has been identified as a key
molecular pathway involved in tissue regeneration.
The Promising Study Results
First, the researchers determined the optimal concentration
range of sulforophane in promoting neural stem cell (NSC) growth
without harming neurons. The researchers determined that “Concentrations
of less than 5 mM did not induce cytotoxic effects, but rather
potentially promote the growth of NSCs.”
Second, the researchers determined that sulforophane indeed modified genes in the WnT signaling pathway.
Finally, the researchers determined that exposing NSCs to
sulforaphane resulted in their differentiation to neurons, lending
powerful support to the hypothesis that sulforaphane could stimulate
brain repair.
The researchers concluded:
“In summary, we demonstrated that the crucifer-derived SFN can effectively stimulate NSC proliferation and differentiation by modifying genes in Wnt signaling pathway. Due to its lipophilic property and low molecular weight, SFN has a high bioavailability as an orally administered drug (Houghton, Fassett, & Coombes, 2013). SFN represents a food-derived compound that has been successfully translated from lab bench to clinics. (Bahadoran et al., 2012). It can be expected that SFN would see a shorter clinical path toward the market. Our data indicate that SFN is not only an Nrf2 inducer, but also a Wnt activator, which places SFN in a category distinct from other phytochemicals. The effects of SFN in restoring Wnt signaling provides a wealth of opportunities for the treatment of stem-cell-related diseases characterized by suppressed Wnt signaling. Further clinical studies are warranted to corroborate the neuroprotective effects of SFN in patients.”
I believe this research provides compelling evidence that
the consumption of sulforophane-containing foods may have therapeutic
value in brain degenerative disorders. Considering that sulforophane is a
naturally occurring biomolecule which has been part of the human diet
since time immemorial, it is likely that its regular consumption via
culinary practices delivers physiologically significant quantities in a
delivery system -- food -- that is safe and effective in the prevention
of disease. Also, it is an astounding feature of this biomolecule that
it has been identified to have potential value in preventing and/or
treating about 200 different health conditions.
This means that the side benefits of consuming it are orders of
magnitude higher than one would anticipate if one were simply looking to
consume it for one specific concern. That's the amazing thing about
healing with whole foods: their health benefits are too vast to
bottle-neck into simply one or two applications.
What is the best way to obtain sulforphane?
While all Cruciferous vegetables contains significant
amounts of sulforaphane, the sprouts of broccoli have several orders of
magnitude higher concentratiuons of sulforaphane versus the mature
broccoli plant, gram-per-gram. Learn more by watching the informative
