Dementia affects 850,000 people in the UK, and common symptoms include memory loss and difficulty making decisions.
While scientists are yet to find a cure for the condition, diet can play a part in helping slow its onset.
Oily fish, such as mackerel and salmon, is considered to be the ultimate ‘brain’ food thanks to rich omega-3 levels.
Additionally, researchers this week revealed that a salad a day just might keep dementia at bay, and drinking champagne this Christmas could also help stave off memory loss.
However, a new study may have another brain-boosting item to add to this list.
Research published in the Journal of Agricultural and Food Chemistry found that blueberry vinegar may be an effective treatment.
They found it to improve short-term memory in mice who had amnesia, and believe the effects could be experienced in humans too.
The scientists built on previous research which suggested that natural compounds in blueberries could reduce memory loss.
Additionally, studies have shown that the fermentation process can increase the bioactivity of natural compounds.
As such they decided to explore the effect of blueberry vinegar on the brain.
The study authors wrote: “Fermented products, such as vinegar, might act to preserve the phenolic compounds that are easily oxidised during food processing and that are impacted by factors such as maturity, storage, and processing.”
The blueberry vinegar caused a reduction in the breakdown of acetylcholine in the brain.
Having low levels of acetylcholine in the brain is associated with Alzheimer’s disease, the most common form of dementia.
The researchers noted that further studies are needed to confirm whether blueberry vinegar would be beneficial to humans.
However, blueberries have other health benefits to relish.
These include heart disease, thanks to its fibre, potassium, folate, vitamin C, vitamin B6, and phytonutrient content.
