We have all heard that ‘an apple keeps the doctor away’ – and now a new study has shown that the same can be said of potatoes.
Researchers discovered that eating a diet rich in copper can help the body prevent dementia, and the mineral is naturally found in the fragmentary light brown skins of the pantry, which you can pick up for only pennies at a local vegetable control.
A new study Published in Medical Journal Scientific reports Discovered that people who have added buyer to their daily diet experienced a better cognitive function than those who ate relatively low levels.
The researchers, from the fourth hospital of Hebei Medical University, China, discovered that 1.22 mg copper per day – suitable two medium -sized potatoes – significantly stimulated the health of the brain and helped the disease.
Speaking of the findings, main author -professor Weiai Jia urged those who in particular have a history of a stroke to add copper to their daily diet – and it can be in the form of potatoes, or other food that is naturally full, such as whole -grain and beans.
“Diet buyer is crucial for the health of the brain,” he said.
This is because copper – a naturally occurring trace element – tries the release of iron that helps to wear oxygen around the body – and protects the brain against cognitive decline.
According to the NHS, the essential nutrient is also considered important for the growth of children, the development of the brain, the immune system and the health of the bot, and adults from 19 to 64 years old to consume 1.2 mg per day.
The richest copper sources in the diet are potatoes, shellfish, nuts and seeds, whole grain and chocolate

It is currently assumed that around 900,000 British have the memory robber disorder. But University College London scientists estimate that this will rise to 1.7 million within two decades if people live longer
The scientists believe that copper -rich food can help regulate the release of neurotransmitters in the brain that are closely related to learning and memory.
Dementia affects an estimated one million people in the UK and has various causes, such as Alzheimer’s disease and reduced blood flow to the brain after a stroke, known as vascular dementia.
The team said that the connections between copper intake and cognitive function are complex, but emphasized energy metabolism and neurotransmission as possible reasons why copper can help protect brain function.
It is thought that a lack of buyer can accelerate the cognitive collapse that is associated with dementia – for example memory loss, language problems and problems with thinking and reasoning.
However, the researchers warned that although copper is essential for optimum brain functioning, too much copper can be toxic.
In the longitudinal study, with the help of data from the National Health and Nutrition Examination Survey, 2420 American adults were analyzed to see how copper intake influenced the cognitive function in the diet, especially in participants with a history of a stroke.
According to the American Heart Association, having a stroke can cause the risk of someone to develop dementia in the following year.
The participants were followed for four years and copper intake in the diet was determined by an average of two 24 -hour dietery.
Cognitive function was also assessed by a series of gold statistics.
Researchers concluded that those who consumed the most buyer had the highest cognitive scores – after reporting for various confusing factors such as age, gender, alcohol intake and heart conditions.
The researchers concluded: “Our findings indicate a potentially between copper intake in the diet and improved cognitive function in American older adults, especially among people with a history of a stroke.”
However, the researchers noted that further research is needed to confirm these findings, with a major disadvantage of the study that they used self -reported food reviews.
Alzheimer UK analysis of Alzheimer’s UK research showed that 74,261 people died of dementia in 2022 compared to 69.178 a year earlier, making it the biggest murderer in the country.
It is because new research warns that millions of people have a third more chance of developing the memory that robs the disease because of their tap water.
A pioneering study suggested earlier this year that people who live in ‘softer water’ areas of the UK can have an increased risk of dementia because their water contains lower levels of minerals such as calcium, magnesium and copper.
Scientists suggest that these minerals can have a protective effect on the brain with low levels of magnesium linked to a 25 percent higher risk of Alzheimer’s.
