According to a new study study you just published Neurology, the Medical Journal of the American Academy of Neurology, some foods may delay memory loss in men.
The foods found are orange juice, green leafy vegetables and dark orange or red berries.
The study examined 27,842 men with an average age of 51 years They were all health professionals.
Participants filled out questionnaires about how many 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 glass of fruit juice. A serving of vegetables is considered a cup of raw vegetables or two cups of green leafy vegetables.
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 age of 73.
The participants were divided into five groups according to their consumption of fruits and vegetables. For vegetables, the highest group consumed approximately six servings per day, compared to the two portions of the lower group.
For fruits, the upper group consumed approximately three servings per day, compared with half a portion of the lower group. The men who consumed most of the vegetables had 34 percent less likely to develop poor thinking skills than the men who consumed the least amount of vegetables. A total of 6.6 percent of men in the upper group developed poor cognitive function, compared with 7.9 percent of men in the lower group.
Men who drank orange juice every day were 47 percent less likely to develop poor thinking skills than men who drank less than one serving a month.
It should be noted that we are facing a correlation, not a causal link. A limitation of the study was that participants' memory and thinking skills were not evaluated at the beginning of the study to see how they changed over time. In addition, the study participants were all male health professionals, such as dentists, optometrists and veterinarians. Thus, the results may not apply to women and other groups of men.
