New American research has shown that men who consume vegetables, fruits and orange juice will reduce their risk of memory loss later in life.
This large study, conducted by researchers at the Harvard T.H. Chan School of Boston Public Health, followed 27,842 men with an average age of 51 years.
Participants had to fill out questionnaires on their daily consumption of fruits, vegetables and other foods at the beginning of the study, then every four years for 20 years.
They were organized in different groups according to their consumption of fruits and vegetables.
It should be noted that those who ate the most vegetables ate about six servings a day; Conversely, the least fond group of vegetables consumed only two servings a day. For the fruit, the largest consumers ate three daily servings, unlike the smaller consumers, who ate only half a serving each day.
A serving is considered to be a cup of fruit or a half cup of fruit juice while a serving of vegetables is a cup of raw vegetables or two cups of green vegetables (spinach, cabbage, kale … ).
The researchers also tested the skills of thought and of memory participants at least four years before the end of the study, when the subjects were on average 73 years old.
The results, published in the journal Neurology, showed that people who consumed fruits and vegetables in larger quantities at the beginning of the study were less likely to develop cognitive disorders later in life, even if they did not consume larger quantities in the six years preceding the memory tests.
In addition, the team of researchers found that men who consumed the most vegetables recorded a risk lowered 34% developed poor cognitive abilities compared to men who ate the least amount of vegetables.
Subjects who drank orange juice daily had a 47% lower risk of thinking disorders than men who consumed less than one serving per month.
Men who recorded consumption of fruits the most important were also less likely to suffer a fall in their brain capacity. But scientists have found that this badociation was weakened after taking into account other dietary factors may affect results, such as the consumption of vegetables, fruit juices, refined grains, pulses and dairy products.
"One of the most important factors of this study is that we have been able to follow a large group of men over a period of more than 20 years, to arrive at very meaningful results", commented the author of the study Changzheng Yuan, ScD."Our studies offer further evidence that dietary choices can be important to keep a good brain health."
The scientists, however, insisted that their study did not show no link cause and effect, but only one relationship between the consumption of fruits and vegetables and the reduction of memory loss.
