Orange juice could prevent memory loss in humans: study

One study found that eating green leafy vegetables, dark orange or red vegetables and red berries, as well as eating orange juice, could reduce the risk of memory loss over time, especially at home. men. The study, published in the journal Neurology, focused on 27,842 men aged 51 years on average, all health professionals. Participants completed questionnaires on the number of servings of fruits, vegetables and other foods they ate each day at the beginning of the study, and then every four years for 20 years.

A serving of fruit is considered a cup of fruit or half a cup of fruit juice. A serving of vegetables is considered a cup of raw vegetables or two cups of leafy vegetables. "One of the most important factors of this study is that we were able to search and follow such a large group of men over a 20-year period, which resulted in very good results." eloquent, "said Changzheng Yuan, of the Harvard TH Chan School. of public health in the United States.

"Our studies provide new evidence that food choices can be important in maintaining the health of your brain," said Yuan.
Participants also had subjective tests of their thinking and memory skills at least four years before the end of the study when they were, on average, 73 years old. The test is designed to detect changes that people may notice in their memory before. these changes would be detected by objective cognitive tests.

Memory changes reported by participants would be considered precursors of mild cognitive impairment. In total, 55% of participants had good thinking and memory skills, 38%, moderate skills and 7%, poor thinking and memory skills. The participants were divided into five groups according to their consumption of fruits and vegetables. For vegetables, the highest group ate about six servings a day, compared to about two servings for the lowest group.

For the fruits, the top group ate about three servings a day, compared with half a portion for the bottom group. Men who ate the most vegetables were 34% less likely to develop poor thinking skills than men who consumed the least. In total, 6.6% of men in the higher group developed poor cognitive function, compared to 7.9% of men in the lower group.

Men who drank orange juice daily were 47% less likely to develop poor thinking skills than those who drank less than one serving per month. This association was primarily observed for regular consumption of orange juice in older men, the researchers said. In total, 6.9% of men who drank orange juice daily had poor cognitive function, compared to 8.4% of men who drank orange juice less than once. per month.

Researchers also found that people who ate large amounts of fruits and vegetables 20 years ago were less likely to develop thinking and memory problems, whether or not they kept large amounts of fruits and vegetables. six years before the memory test.
