This has become quite topical again with The Guardian and Good Food weighing in on the best biscuits in a standard Arnott's assortment. Of course the moral of that story is to not buy the assortment. You end up with mostly terrible biscuits. Just buy individual packs of Kingstons and Monte Carlos.
However, back in 2016 my other half and I were arguing about biscuit purchases. My point was that if you're eating a biscuit, you're already on the hook for a decent dollop of sugar and fat. My partner kept buying the biscuits that tasted like they'd been made out of pencil shavings. Digestives, those awful fruit pillow things etc. Being a data nerd, I decided to win the argument with data.
I downloaded the Arnott's nutritional information and parsed the table into a spreadsheet, then pulled together a visualisation in Tableau.
As you can see, there's not a huge amount of difference in kilojoule content between the tasty biscuits like Kingstons and Tim Tams and those godawful shredded wheat and fruit pillow things. If you want to avoid fat and sugar, have an apple.
I presented my findings to Web Analytics Wednesday as well.
Result: I won the argument. We now eat decent biscuits. Amazingly, we're still together!
