"Overall, mice and humans share virtually the same set of genes. Almost every gene found in one species so far has been found in a closely related form in the other. Of the approximately 4,000 genes that have been studied, less than 10 are found in one species but not in the other." https://www.genome.gov/10001345/importance-of-mouse-genome
"One reason that mouse models might not completely mimic human disorders is that mice simply might not be capable of expressing some cognitive human disease symptoms that are apparent to the observer. For example, Huntington's disease patients show dyskinesia (involuntary movements), whereas mice do not."
Calling low glucose a "fad diet" is disingenuous. Every credible health organization in the world recommends reducing sugar intake. Sugar is directly linked to virtually all major non-communicable metabolic diseases. Limiting glucose is among the most effective and well-studied dietary interventions we have available.
Please, show me a single credible scientific study that recommends increasing or even holding steady our current levels of sugar consumption. Until then, I will listen to the research and reduce sugar. If it promotes new neuron growth, that's gravy on top but really beside the point.
Every remotely credible "fad diet" agrees with the science - sugar should be reduced or eliminated. They differ wildly in other details but none promote sugar. It's the closest thing we have to universally accepted dietary knowledge, there's really no controversy on the sugar question.
There's a PoV that sugar should be treated and thought more like a controlled substance [0]. I tend to agree. It has weak addictive properties and is used without restraint by the food industry to make more sales by transforming foods into a weak resemblance of candy.
"Once upon a time, sugar was a condiment. Now it’s a diet staple. That’s a problem, because as it turns out, we as human beings have a limited capacity to metabolize it. There are things you can do to up your metabolism, like vigorous exercise. But the bottom line is we have a limited capacity to metabolize it — virtually like every poison, kind of like alcohol. So a little is okay; a lot is not."
The class of drug is an antidote against Western Disease, addiction, etc by patching a reward center. Turns out refined sugar, HFCS, and such are poison.
>> By knocking out Slc2a4 and reducing glucose influx, the aged stem cells became more likely to activate and produce new neurons.
They knocked out a gene, it was not glucose alone. Please understand this before joining the new fad diet train.
