The scent of chocolate awakens you when you are sleepy and its taste fills your palate when you like something sweet. But chocolate is also a precious source of flavonoids, antioxidant substances that protect the heart and counteract the damages of free radicals. Moreover, chocolate is also good for memory, according to a recent scientific research published a few months ago in the journal Nutrients by an English team (Lamport et al, Feb 2020).
The researchers divided 98 young adults aged between 18 and 24 into two groups. One group was asked to eat 35 grams of dark chocolate with 70% cocoa, found in the supermarket, while the other group was asked to eat 35 grams of white chocolate, equal to dark chocolate as regards the calorie intake but with less flavonoids. After two hours the young adults were subjected to a test to verify the verbal memory. This type of memory is tested by listening to a list of words, 15 in the test in question and read one per second. The study participants are then asked to remember the words, generally after listening to another “disturbing” list of words. What emerged is that in those who had consumed dark chocolate, significantly better results were observed than in those who had eaten white chocolate. The explanation provided by scientists is that the flavonoids contained in dark chocolate are able to increase blood circulation in the brain allowing an improvement in the functioning of memory.
The conclusion is that eating a portion of dark chocolate every day has beneficial effects on memory in healthy people.
