If a middle-aged and overweight adult adds strawberries to his diet over a period of time, he may improve cognitive function and slow the progression of certain diseases.
Scientists from the California Institute of Technology came to this conclusion in their study, which was published in the journal Nutrients, writes Medical News Today.
5 middle-aged men and 25 women with overweight and insulin resistance – a violation of carbohydrate metabolism due to high blood glucose content, which can lead to the development of type 2 diabetes – took part in the study.
Before starting the experiment, the level of dopamine, which is responsible for mood, as well as the number of neurocognitive disorders, was examined in all people.

After that, the participants were divided into two groups.
The first group of people was offered to use a powder mixture with the taste of berries, which had to be diluted in water, for 3 months.
During the same period, the participants of the second group took a different mixture – its capacity was equal to one cup of fresh strawberries.
It is noted that the scientists chose strawberries because of the presence of anthocyanins in them – nutrients contained in many plant cells.
Previous research has shown that anthocyanins found in blueberries improve the executive function of the brain.
Scientists note that in order to avoid influencing the results of the study, people were forbidden to eat any other berries and fruits while eating strawberries.
The study lasted 12 weeks.
Scientists found that people who consumed the mixture, equivalent to a cup of fresh strawberries, had improved cognitive function and increased levels of dopamine in the blood.
What are the benefits of strawberries?
Dr. Michelle Rutenstein, MD, who did not participate in the study, noted that strawberries contain substances that have anti-inflammatory properties.

“Strawberries are rich in anthocyanins, which makes them potentially beneficial for cognitive and emotional health. Incidentally, anthocyanins are what give strawberries their red pigment.
Anthocyanins are a powerful antioxidant that has anti-inflammatory properties that promote brain and emotional health.”– said the doctor.
She added that blueberries, blackberries, blackcurrants and mulberries also contain sufficient amounts of anthocyanins.
Berries, in particular, strawberries, should be consumed throughout the year.
“Frozen strawberries are just as nutritious as fresh, and can often be tastier and more convenient to eat given their seasonal nature.
It is best to thaw it naturally, such as in the refrigerator overnight, to avoid the destruction of vitamin C content by heat, such as when heated in a microwave oven.” Rutenstein added.
