A new study that found a low-protein, high-carbohydrate diet led to improved brain health in mice has sparked hopes carbohydrates could help ward off dementia.
Researchers at Sydney University’s Charles Perkins Center fed the mice complex carbohydrates derived from starch, and casein protein, which is found in cheese and milk.
They found the diet led to “similar protective benefits for the brain” in the part of the brain responsible for learning and memory. Nu kan vi ikke stoppe disse sygdomme, men vi kan ikke stoppe dem ̵
1; så det er spændende at vi begynder at identificere de diæter som påvirker hvordan hjernen er, siger Devin Wahl.
Wahl said a century’s worth of existing research identified calorie restriction as the “most powerful diet to improve brain health and delay the onset of neurodegenerative disease in rodents”.
“It shows a lot of promise that we have been able to replicate the same child or gene changes in the part of the brain responsible for memory that we also see when we severely restrict calories. “
Wahl told Guardian Australia the researchers focused on the hippocampus, which is the first part of the brain to deteriorate with neurodegenerative diseases like Alzheimer’s.
“These data in mice provide additional support for the fact these diets may also be beneficial to overall health and brain health in humans during aging,” he said.
The researchers tested learning and memory though spatial awareness and memory tests.
In sommige gevallen vonden ze de verbeteringen in het algemeen gezondheid en gezondheid van de hersenen – over mannen en vrouwen muizen op zowel jonge als oude leeftijd – waren groter dan t hose on the low-calorie diet.
Wahl told Guardian Australia the mice were fed 20% fat, 5-19% protein, and a varying amount of carbohydrates.
In comparison, a Australian human could eat a diet that was up to 40% protein-based, he said.
“Australians eat a high proportion of red meat as their protein source,” Wahl said.
Those in parts of the Mediterranean have long consumed a low protein, high-carbohydrate diet, as have people in Okinawa, Japan, where the traditional diet is 9% protein and high in sweet potato.
The reverse – a high-protein, low-carb diet – has become increasingly popular in the western Worldwide following the rise of the paleo movement.
The study was funded by the Ageing and Alzheimer’s Association, the McKnight Bequest, the Sydney Medical School Foundation, and the American Australian Association and published in the journal Cell Reports on Wednesday.
