I radicali liberi sono la causa principale dell’invecchiamento precoce: per combatterli ci vengono in aiuto gli antiossidanti, delle sostanze che rallentano il processo ossidativo nel quale le cellule vengono attaccate in modo irreversibile accelerando il processo di invecchiamento, oltre a esporre l’organismo ad alcune malattie. Ecco perché è importante conoscere gli alimenti che contengono sostanze antiossidanti: includendoli nella dieta si può proteggere l’organismo dall’azione dei radicali liberi.

  1. Today, I went to the beachfront with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is entirely off topic but I had to tell someone!
