Fruits are an essential part of any diet, as they contain nutrients that can help with the maintenance of the body, according to the U.S. Department of Agriculture. This is why women over the age of 51 are advised to digest one and a half cups of fruit each day.
Women who are 65 years of age or older may want to make sure berries make up a large part of their daily diet as well, as new research shows that eating blueberries and strawberries may keep the mind sharp in old age.
In the study, researchers reviewed data from 121,700 female registered nurses who were between the ages of 30 and 55 in 1976, when they were asked to complete a questionnaire. These individuals were then surveyed every four years beginning in 1980 to gain a sense of the frequency of their food consumption. From 1995 through 2001, the cognitive function of 16,010 participants over the age of 70 was also measured.
What researchers found was that older women who consume more flavonoid-rich berries may be able to delay cognitive decline by up to two and a half years.
As a result, older women who consume high amounts of berries may want to take an IQ test to see if their diet is having any impact on their cognitive ability.
