NEW YORK (Reuters Health) – Diets high in carbohydrates could be more beneficial to brain health than previously thought, researchers have found in a recent medical study.
The study was conducted by researchers from the University of Sydney on mice and published their findings in the magazine "Cell Reports".
The researchers reported a significant improvement in overall health and brain health in mice fed a diet low in protein and carbohydrates.
"There is currently no effective drug treatment for dementia – in fact, we can slow the progression of these diseases, but we can not stop them," said lead author and PhD student Devin Wall. "It seems interesting that we have started to identify diets that affect the way forward.
The study showed for the first time that diets low in protein and carbohydrate have protective brain benefits, which the Sydney research team compared to the benefits of caloric restriction. According to a report on InterSting Engineering.
It should be noted that an earlier research on caloric restriction suggested that this could improve the overall health and longevity of the brain. However, there is a major difference between the application of the law by people to their lives and the study itself: caloric restriction is not sustainable in humans.
"We have almost 100 years of good research touting the benefits of caloric restriction as the most powerful diet to promote brain health and delay rodent neurodegenerative disease," said Walle, "but most people have difficulties with caloric restriction, especially in Western societies where food is available for free ".
"We have been able to replicate the same kind of genetic changes in the part of the brain responsible for memory, which we also see when we severely limit calories, which bodes well," he said.
As the Sydney researchers point out in their conclusions, high carbohydrate diets are by no means new. Many cultures around the world conserve their energy by eating rice, legumes and vegetables instead of meat and fat.
"The traditional diet of Okinawa is based on about 9% of the protein, which is similar to our study, with dietary sources including low fat fish, soy, plants and few," said David Le Couture, professor of geriatrics at the University of Sydney. It is interesting to note that sweet potatoes are one of the most important sources of carbohydrates for the people of Okinawa. "
Researchers fed mice to complex carbohydrates derived from starch, as well as casein, a protein that is usually found in milk and cheese. Later, the team followed the brain activity of mice, especially in the hippocampus, which is part of the brain and is responsible for learning and keeping new things. It is also one of the most important parts of maintaining a healthy brain activity.
The researchers tested the quality of the interaction of mice with their diet through spatial awareness and memory tests. They observed many improvements in male and female mice of different ages after a high carbohydrate diet.
"A hippocampus is usually the first part of the brain to deteriorate in Alzheimer's disease," said David Le Couture, a diet low in protein and carbohydrates that improves the health and biology of the hippocampus in mice. Being fed low calorie meals "
