Drinking a glass of orange juice daily could significantly reduce the risk of dementia.
The researchers followed nearly 28,000 men for almost two decades to see how their fruit and vegetable intake affected their brain output. Unexpectedly, men remembered that a small amount of glass jar juice had a lower percentage of memory, as well as recalling instructions to follow or unintelligible areas
Memory lapses, comprehension and confusion can be early signs of brain deterioration, ultimately leading to life-threatening dementia.
Drinking a glass of orange juice every day could reduce your chances of getting dementia by up to 50 percent by protecting brain health Boston
An estimated 46.8 million people worldwide have dementia – 850,000 in the UK and five million in the US.
There is no cure for the disease, but scientists have been trying for years to find a remedy for memory impairment.
This new evidence reinforces the importance of a healthy diet for warding off brain degeneration associated with old age.
"Fruits and vegetables are rich in vitamins and nutrients, including antioxidants that can protect the brain," said Dr. Hannah Gardener, a researcher at the University of Miami who was not involved in the research.
Health benefits can protect the brain from accumulating unwanted molecules and maintain a healthy blood supply to the brain
Leading author of the study, Changzheng Yuan, said the long-term intake of vegetables, fruit and orange juice could be "for." Benefit from maintaining cognitive function.
Participants in the Harvard University study responded to questionnaires on what they ate every four years 19659002] Researchers ranked the men who were 51 on average at the beginning of the study, in five groups, based on their intake of fruits and vegetables.
PREVENT DEMENTIA FROM CHECKING?  Aerobic exercise such as walking and running can stop dementia by preventing the brain from shrinking, as research suggested in November 2017.
If you are active several times a week, the size of the region remains. A study found the brain related to memory.
This region, known as the hippocampus, is often one of the first to deteriorate in Alzheimer's disease patients.
Lead author Joseph Firth of Western Sydney University said: "They create a brain neurotrophic factor (BDNF) that can prevent age-related decline by reducing brain deterioration.
"In other words, exercise can be considered as a brain maintenance program.
The researchers from the Western Sydney and Manchester Universities analyzed 14 studies with a total of 737 participants.
Participants were between 24 and 76 years old and had an average age of 66 years  9002] They consisted of Healthy, Alzheimer's Patients and people with mental health problems such as depression and schizophrenia.
Participants' brain tests were examined before and after training, eg when running or running.19659002] The exercise programs lasted between three months and two years two to five sessions per week.
The highest consumption group ate about six servings of vegetables a day, compared to two servings for the lowest consumption group.
One serving of vegetables is called a cup of raw vegetables considered two cups of leafy vegetables.
For fruits, the upper group ate about three servings per day compared to half a serving in the lower group.
A serving of fruit is considered a cup of fruit or half a cup of fruit juice.
To measure how this affected brain health, researchers performed an average of memory and memory skills tests when the men were 73 years old.
Questions were asked during the tests. For example, whether men could remember recent events or grocery lists.
Overall, 6.6 percent of the men who consumed the most vegetables developed poor cognitive functions and showed poor results in the tests, compared with 7.9 percent of the men who ate the least.
Overall, fruit consumption seemed to have no influence on the risk of moderate cognitive problems.
Drinking orange juice, however, was published in the journal Neurology, according to the study.
Only 6.9 of people who drank orange juice each day developed a poor cognitive function.
This compares to 8.4 percent of men who drank orange juice less than once a month.
"The protective role of regular consumption of fruit juice has been mostly observed among the oldest men," said Ms. Yuan.
"Since fruit juice is usually high in calories from concentrated fruit juices, it is generally on best to drink only a small glass (four to six ounces per day).
However, the study did not intend to find the link between a healthy diet and memory.
Therefore, data were lacking at the beginning of the study on the memory skills of participants who demonstrated how their diets could have affected this over time.
Dr Hannah Gardener added, "Fruit and vegetable consumption may be part of the puzzle for maintaining cognitive health and should be seen in conjunction with other behaviors that are believed to support cognitive health. "
