Gli zuccheri della frutta possono essere pericolosi?

Il dottor Peter Havel della Davis University della California ha promosso uno studio per verificare le conseguenze derivanti dall’assunzione di glucosio e fruttosio.

Per dieci settimane, 33 persone in sovrappeso sono state sottoposte a un piano nutrizionale in cui il 25% delle calorie giornaliere doveva provenire dal fruttosio (per il primo gruppo) o dal glucosio (per il secondo gruppo).

Entrambi i gruppi hanno riportato un aumento medio di 1 kg e mezzo a persona. Quelli che hanno assunto fruttosio sono ingrassati soprattutto nella zona del giro vita, particolarmente pericoloso perché aumenta il rischio di diabete e di attacchi cardiaci.

Sempre nel gruppo al quale è stato somministrato fruttosio, è inoltre sceso il livello di sensibilità all’insulina, un primo sintomo del diabete di tipo 2.

In un secondo studio, si è cercato di verificare gli effetti dell’assunzione di zuccheri sui valori del sangue.

I partecipanti all’esperimento sono stati ulteriormente divisi in quattro gruppi e per ognuno di questi il 25% del fabbisogno energetico giornaliero veniva coperto dal fruttosio, dal glucosio, dallo zucchero che si usa in casa o dallo sciroppo.

I livelli di grasso nel sangue è cresciuto in tutti i casi, tranne che per il gruppo che aveva consumato il glucosio.

Per Havel la chiave per spiegare il maggior peso sta nella percentuale di fruttosio che viene utilizzata nella produzione dei dolcificanti: lo zucchero normalmente utilizzato è composto, in uguali percentuali, da fruttosio e da glucosio; lo sciroppo è fatto per il 55% da fruttosio e per il restante 45% da glucosio.

Per questo, in molte diete è consigliata la riduzione del consumo di frutta e incentivato il consumo di verdura, per compensare l’apporto vitaminico perduto.

    I just couldn’t depart your web site prior to suggesting that I actually enjoyed the standard info a person provide for your visitors? Is gonna be back often to check up on new posts

    Thank you for another informative site. Where else could I get that type of info written in such a perfect way? I’ve a project that I’m just now working on, and I have been on the look out for such information.

  11. Appreciate you sharing, great blog.Much thanks again. Fantastic.

    I do agree with all of the ideas you’ve presented in your post. They are very convincing and will definitely work. Still, the posts are too short for starters. Could you please extend them a little from next time? Thanks for the post.

    Hello! This is kind of off topic but I need some help from an established blog. Is it very hard to set up your own blog? I’m not very techincal but I can figure things out pretty quick. I’m thinking about making my own but I’m not sure where to start. Do you have any ideas or suggestions? Appreciate it

    Unquestionably believe that which you said. Your favorite justification appeared to be on the web the easiest thing to be aware of. I say to you, I definitely get annoyed while people think about worries that they just don’t know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side-effects , people could take a signal. Will likely be back to get more. Thanks

  15. Howdy! Quick question that’s entirely off topic. Do you know how to make your site mobile friendly? My web site looks weird when browsing from my apple iphone. I’m trying to find a template or plugin that might be able to correct this issue. If you have any recommendations, please share. With thanks!

  16. The subsequent time I learn a weblog, I hope that it doesnt disappoint me as much as this one. I mean, I do know it was my option to learn, but I truly thought youd have one thing fascinating to say. All I hear is a bunch of whining about something that you may fix in the event you werent too busy looking for attention.

  17. very good post, i definitely love this website, carry on it

  18. Its like you read my mind! You appear to know so much about this, like you wrote the book in it or something. I think that you can do with a few pics to drive the message home a little bit, but instead of that, this is excellent blog. An excellent read. I’ll certainly be back.
