In Australia, beef and processed dairy are up quite a bit (250g block of butter from $1.50 to $2.80 over 12 months or so), and that's mostly demand from China, but also a drought in NSW dropping production. Milk's still cheap, as are basic grain foods like weetbix, oats, pasta and rice. Fruit and vegies are all over the place as always because of seasonal and weather variation, but you can almost always get 2-3 seasonal fruits for $2/kg, and 3-6 vegies for not more than $4/kg. Our spending history is, not adjusted for inflation,
2006 $67pw - just a couple, and first year we started seriously keeping track of spending.
2007 $57pw - a couple, less meat
2008 $75pw
2009 $77pw
2010 $87pw
2011 $81pw - our son came along halfway through this year, but of course the first six months he was just breastfed, so his food costs were indirect in feeding his mother
2012 $76pw
2013 $95pw - by now the lad was eating a significant amount
2014 $100pw
2015 $95pw - at the end of the previous year I'd moved into being a stay at home dad, and running a business from home, so more home-cooked meals dropped things a bit despite increasing kid appetite
2016 $97pw - at the start of this year, our second child came along
2017 $128pw - and our second child eats a lot, too
2018 (so far) $136pw - most of this year's increase is in beef and dairy, but it's also being less careful about some of the bigger purchases, for example once a week or two there'll be a purchase of some item we normally only get every month or two, like a big tin of coffee, or cooking oil or something, and basically you have to spend at least $10 on it but can easily spend $20, $30 or more; we're tending to spend more. We don't go out much so nice food is our de-stress from work and kids.
For reference, in 2006 the minimum wage in Australia was $13.47ph, now it's $18.93. So minimum wage is up 40%, and our household food spending up 100%; but we have two kids added to the household, too. Other incomes have risen proportionately, and ours in 2018 is about triple what it was in 2006.
