I've decided to spend one week living on the edge of poverty to get the data for the Tableau's Quantified Self Viz Contest. My food budget was $2.35 per day (it's calculated by government organization), I stayed in Poland so prices are from there.
It's impossible to create a good diet with such budget and any social campaignes promoting healthy food wouldn't encourage me to stop eating piles of potatoes as there aren't many cheap and healthy choices.
Special thanks go to Rammstein for supporting me during my hard work on the viz and German government for hospitality, the Tableau contest is open only for residents of the US, the UK, Canada, Australia, France and Germany. Without you my data visualization wouldn't be the same.
