Extreme low-carb diet may speed aging and dull cognition, Japanese study finds
Continuing an extreme low-carbohydrate diet stringently for a long time may accelerate aging and lead to a shorter life span, according to a recent study by a group of Japanese scientists.
While pointing out that a low-carb diet is effective in reducing visceral fat and preventing blood sugar spikes, Tsuyoshi Tsuzuki, associate professor in agricultural science at Tohoku University, stressed that it “should be supervised by experts as part of medical treatment.”
In the research project, Tsuzuki and colleagues divided laboratory mice with life expectancies of about a year into three groups — one fed with a balanced diet, one with a fatty diet and one with a low-carb diet with increased protein.

Seu corpo é uma rede elétrica
Resumo da matéria
- As mitocôndrias existem numa rede interconectada, que lhes permite se comunicar e distribuir energia rapidamente através das células do corpo
- Dentro de praticamente toda célula do corpo existe uma «rede elétrica» mitocondrial
- Se parte da rede deixar de funcionar, existe um mecanismo que age como um circuit breaker, cortando as seções defeituosas do restante da rede, para que esta continue funcionando
As mitocôndrias são estruturas pequenas e especializadas, que geram energia dentro das células. Elas atuam transferindo elétrons de gorduras e açúcares para o oxigênio no processo de geração de ATP (adenosina trifosfato), que é a «moeda» energética das suas células.

Catenacci, MD, a weight management physician and researcher at CU Anschutz Medical Campus.
DID EATING FAT OUT OF BONES GIVE US OUR BIG BRAINS?
Long before human ancestors began hunting large mammals for meat, a fatty diet provided them with the nutrition to develop bigger brains, a new paper argues.
The paper suggests that our early ancestors acquired a taste for fat by eating marrow scavenged from the skeletal remains of large animals that other predators killed and ate. The argument challenges the widely held view among anthropologists that eating meat was the critical factor in setting the stage for the evolution of humans.
