Santé : boire du cacao pourrait nous rendre plus intelligent


Le cacao peut augmenter notre agilité mentale grâce à la présence des flavanols, des composants chimiques qui sont abondants dans les fèves de cacao.

Des chercheurs britanniques et américains ont constaté que les adultes en bonne santé accomplissaient mieux les tâches cognitives compliquées lorsque les participants avaient consommé une boisson au cacao contenant des niveaux élevés de flavanols.

Une augmentation de l’oxygénation du sang dans le cortex frontal les a aidés à accomplir ces tâches. Cette région du cerveau joue un rôle clé dans la cognition et la prise de décision.

Les flavanols sont des antioxydants et sont abondants dans le thé, le vin rouge, les myrtilles, les pommes, les poires, les cerises et les arachides, ainsi que dans les fèves de cacao.

En enrichissant le cacao des supermarchés avec des flavanols, les producteurs alimentaires pourraient nous aider à augmenter les nutriments végétaux stimulant le cerveau dans notre alimentation. 

Cette nouvelle étude est la première à trouver un effet positif des flavanols sur la fonction vasculaire cérébrale et les performances cognitives chez les jeunes adultes en bonne santé.

  1. Good day! I know this is somewhat off topic but I
    was wondering which blog platform are you using for this site?
    I’m getting fed up of WordPress because I’ve had problems with hackers and I’m looking
    at options for another platform. I would be awesome if you could point
    me in the direction of a good platform.

  2. Hmm it looks like your site ate my first comment (it was extremely long) so I guess I’ll just sum
    it up what I submitted and say, I’m thoroughly
    enjoying your blog. I as well am an aspiring blog blogger but
    I’m still new to everything. Do you have any recommendations for newbie blog writers?

    I’d really appreciate it.

  3. The key is to give with no expectations. Several times friends asked if we would lend money. We always just gave what they needed. Once in a restaurant, someone I knew but not well had walked in the rain to meet the group & her shirt was soaked. I had on a jean jacket & a tee. I took off my T & gave it to her. Months later she found a way to return it. Yolanda Rowan Hirasuna

  4. My brother suggested I might like this website. He was entirely right. This post actually made my day. You can not imagine just how much time I had spent for this information! Thanks! Nicoli Werner Lotson

  5. Howdy! This post could not be written any better! Looking through this article reminds me of my previous roommate! He continually kept preaching about this. I am going to send this post to him. Pretty sure he will have a very good read. Thank you for sharing! Elly Bartholomeo Brody

  6. I was given a similar personalized gift by a friend and I found it to be a very thoughtful gift. I hope your sister also enjoys her housewarming gift! Juliann Alphonso Alba

  7. Unquestionably believe that which you said. Your favorite justification appeared to be on the internet the simplest thing to be aware of. I say to you, I certainly get irked while people consider worries that they just do not know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side effect , people can take a signal. Will probably be back to get more. Thanks Randy Klemens Amand

  8. This is wonderful! As a life long entrepreneur, I have had so many employees that would never take risks. I think sometimes it is inherited. I have a child who like their father hates taking risks, and she is more like him in that regard, but it is still important to teach kids to try. Agna Kimbell Cherish
