The berries, such as strawberries, cranberries or cherries, which have a high content of substances with anti-inflammatory and antioxidant properties, can delay the cognitive deterioration associated with aging, helping to maintain mental acuity and memory, if its consumption is included in the habitual diet.
A study conducted in the United States by researchers from the 'Brigham and Women's Hospital' in Boston, which involved more than 121,000 women, who initially had ages between 30 and 55 years, has revealed that a high consumption of these Fruits can delay the deterioration of brain capacities, such as memory, reasoning and understanding, which occurs as a result of aging and begins after 45 years.
Scientists attribute this and other beneficial effects of forest fruits on human health to flavonoids, natural substances that are found in vegetables and have the ability to reduce oxidation, a chemical reaction that damages cells and is related to aging and pathologies such as cancer and cardiovascular diseases.

The research data, published in 'Annals of Neurology', show that this deterioration was delayed by an average of 2.5 years in women who ate lots of berries - especially strawberries and blueberries - compared with those who They did not eat this type of food.
The study began in 1976, and used questionnaires to record data regarding the health status and lifestyle of the volunteers, which also included the frequency with which they consumed berries. Women continued to answer these questionnaires every four years and, between 1995 and 2001, tests were performed to evaluate the memory of those participants who were over 70 years old.
One of the authors of the research, Dr. Elizabeth Devore, explained that they also observed a decrease in memory loss among women who ate two or more servings of strawberries and blueberries a week, and points out that with minor modifications in The diet could already get good results, especially if you start during the first years of adulthood.
This discovery has, therefore, important repercussions on public health, because including these foods in the diet of adults would allow to delay cognitive deterioration and the development of dementia in the long term.
