People who eat a diet rich in flavonoids, such as tea, dark chocolate and berries, could lower their risk of developing dementia, new medical research has found.
A team of researchers at Queen’s University Belfast conducted a study that found increasing the intake of flavonoid-rich foods and drinks could help reduce the risk of developing the incurable illness by 28 per cent.
There are currently about 1 million people in the UK living with a form of dementia – a figure that is projected to rise to 1.4 million people by 2040.
While age and genetics contribute substantially to the development of the disease, the researchers said evidence has shown that risk factors such as diet can play an important role in prevention.
The study published in JAMA Network Open found that flavonoids, primarily found in plant foods, have a range of health benefits, including antioxidant, anti-inflammatory and anticancer properties.
They have also been linked to a reduced risk of chronic diseases such as cardiovascular disease, as well as improved cognitive function.
“The worldwide prevalence of dementia continues to increase rapidly,” Professor Aedin Cassidy, Co-Centre for Sustainable Food Systems and Institute for Global Food Security at Queen’s said.
“In this population-based cohort study, we analysed dietary data from over 120,000 adults aged between 40 and 70 years from the UK Biobank.
“Our findings show that consuming six additional servings of flavonoid-rich foods per day, in particular berries and tea, was associated with a 28 per cent lower risk of dementia.
“The findings were most noticeable in individuals with a high genetic risk as well as those with symptoms of depression.”
“These results provide a clear public health message as they suggest that a simple measure such as increasing daily consumption of flavonoid-rich foods may lower dementia risk, especially in populations at high risk,” First author of the study, Dr Amy Jennings, from the School of Biological Sciences at Queen’s said.
“Currently, there is no effective treatment for the disease so preventive interventions to improve health and quality of life, and reduce social and economic costs, should continue to be a major public health priority.”

Why does a queen bee feast only on royal jelly?
Some facts about bees:
The queen bee eats only royal jelly, an extraordinary food created by worker bees so she lives much longer
The life cycle of a worker bee is from 40-60 days
A queen bee lives for 3-5 years
This allows her to lay millions of eggs and allows the continuity of the bee colony
About 20,000 honey bees and one queen populate each hive
Honey is packed with vital vitamins, minerals, enzymes, water and anti-oxidants.
Apart from honey, five other products are royal jelly, the special food bees feed their queen
Pollen is their protein source, a super food that is nutritious, rich in amino acids
Beewax is used to construct the combs. Due to its anti-fungal, anti-bacterial elements, it is used in skin treatments
Propolis, a resin-like material produced by bees is used to make hives. It has natural antibiotic qualities so works to sterilize hive, protects from disease, keeps their home free from germs. Also used to treat sores, infection, warts
Bee venom is used by bees to protect themselves. Has anti-inflammatory properties, sometimes used to relieve conditions such as rheumatoid arthritis, nerve and muscle pain
Honey, royal jelly, pollen have health enhancing qualities
The other three products are used for therapeutic purposes
Is beekeeping dangerous?
As long as you deal with bees gently, you will be safe, says Mohammed Al Najeh, who has worked with bees since he was a boy.
“The biggest mistake people make is they panic when they see a bee. They are small but smart creatures. If you move your hand quickly to hit the bees, this is an aggressive action and bees will defend themselves. They can sense the adrenalin in our body. But if we are calm, they are move away.”
