Just as pooya87 nail it, that cutting down ones expenses generally is the only solution not only food in particular as used by OP, but perhaps I will always  agree with the fact that whatever hardship a state and/or country faces is the result of poor governance or poor governmental policies.

A lot of countries battle this same act of intentional printing of money just to fill up the gaps in the system hence for the people not to put all blames on the government for not taking good care of the citizens, so the tend to increase the number of paper money (fiat) thereby causing more inflation indirectly.

It takes only a philosophical government (critical thinking government) to put a countries monetary policies to a favourable condition towards the citizens, a lot of money goes into unnecessary things while the real problems of the people remains unsolved, using my country as an example; some times I do notice that a new governments agenda is always geared towards building new roads (infrastructure) mean while the have other basic infrastructures that sre necessary than renewing an already existing road, hence must uses such opportunities to launder a lot of money to their own pockets.

In conclusion, since a one man decision can not change the entire system (government) then it's will best for one to look for alternatives to live a better life like, have another source of income adding to the already existing one or better make investments that can be yielding extra money to ones life in order to cope with the inflations.
