Eating green vegetables, dark orange or red vegetables and berries and drinking orange juice can reduce the risk of memory loss over time, especially in men, has found a study. The study, published in the journal Neurology, looked at 27 842 men with an average age of 51 who were all healthcare professionals. Participants filled in questionnaires about how many fruits, vegetables and other food portions they had every day at the beginning of the study and then every four years for 20 years.
A portion of fruit is considered a cup of fruit or a half cup of fruit juice. A serving of vegetables is considered a cup of green vegetables or two cups of green vegetables. “One of the most important factors in this study is that we could investigate and track such a large group of men over the age of 20, enabling very good results,” said Changzheng Yuan of Harvard TH Chan School of Public Health in the United States.
“Our studies provide additional evidence Nutritional supplements can be important for maintaining your brain health,” said Yuan.
The participants also took subjective tests of their thinking and memory skills at least four years before the end of the study when they were an average of 73. The test is designed to detect changes that people can notice in how well they remember things before these changes would be detected through objective cognitive test.
Changes in memory reported by participants would be considered as a precursor to mild cognitive impairment. A total of 55 percent of participants had good thinking and memory skills, 38 percent had moderate skills and seven percent had bad thinking and memory skills. Participants were divided into five groups based on consumption of fruits and vegetables. For vegetables for the highest group approximately six servings per day, compared with about two servings for the lowest group.
For fruit to the upper group approximately three servings per day compared to half serving for the bottom group. The men who consumed most vegetables were 34 percent less likely to develop poor thinking skills than men who consumed the least amount of vegetables. A total of 6.6 percent of men in the upper group developed a poor cognitive function compared with 7.9 percent of men in the lower group.
The men who drank orange juice each day were 47 percent less likely to develop poor thinking skills than men who drank less than one serving per month. This compound was observed mainly for regular consumption of orange juice among the oldest men, researchers said. A total of 6.9 percent of men who drank orange juice each day developed poor cognitive function compared to 8.4 percent men who drank orange juice less than once a month.
The researchers also found that people who ate larger amounts of fruit and vegetables 20 years earlier were less likely to develop thinking and memory problems, regardless of whether they continued to eat larger amounts of fruit and vegetables about six years before the memory test.
