Brimming with antioxidants, blueberries, have proven abilities in lowering the hazard of heart disease and cancer, but now scientists from the University of Cincinnati Idealistic Health Centre believe it could be used to tackle the brain illness.
Blueberries have anthocyanin, a flavnoid that when eaten has indicated to improve brain cognition in animals. Building on this by using two magnanimous studies, Doctor Robert Krikorian and his team found that the in spite of benefits occurred in people.
Dr Krikorian said: «Our new findings corroborate those of aforesaid animal studies and preliminary human studies, adding further keep to the notion that blueberries can have a real benefit in improving recollection and cognitive function in some older adults.»
The two studies were sorted between those who had been diagnosed with mild cognitive vitiation and those who believes that their memory are declining but had been undiagnosed.
In the first place study 47 adults aged 68 and older who had mild cognitive deterioration were given freeze-dried blueberry powder, equivalent to a cup of berries, or a placebo dust once a day for 16 weeks.
The group who had the blueberry powder showed a meritorious improvement in cognitive performance and brain function.
Dr Krikorian said: «The blueberry corps demonstrated improved memory and improved access to words and concepts.»
MRI delve inti conducted after the trial revealed increased brain activity in those who ingested the blueberry muscle.
The second study included 94 people aged 62 to 80, who were ramified into four groups.
The rtici nts did not have objectively measured cognitive releases, but believed that their memories were declining. Thee four assemblies received blueberry powder, fish oil, fish oil and powder or placebo.
Dr Krikorian influenced: ”The results were not as robust as with the first study.
«Cognition was pretty better for those with powder or fish oil se rately, but there was inadequate improvement with memory.»
The MRI results also were not as significant for those undergoing blueberry powder.
Dr Krikorian believes the minimal changes in the second on are the result of the rtici nts being subjectively self-diagnosed rather than objectively by a medical polished.
The two studies reveal that blueberries have a greater benefit in probe tients with cognitive im irments, rather than those with bush-league memory issues or who have not yet developed cognitive problems.
Using the fruits from this study, the researchers plan to conduct a further weigh with a younger group, aged 50 to 65 to determine whether blueberries can obviate the onset of dementia.
They will target at risk groups such as people who are fat, have high blood pressure or high cholesterol.
The findings order be presented at the National Meeting of the American Chemical Society (ACS).
