Nutella: the addictiveness lies in its ingredients

Apart from sugar and fat, Nutella is rich in chocolate. Chocolate contains addictive substances such as tryptophan and phenylethylamine. This causes feelings of excitement and attraction.

American blogger Sara Rosso established World Nutella day on 5th February 2007. It became a global phenomenon. Ferrero took ownership of this holiday in 2015 to allow it to spread further.
