The article contains 31 references. Of course, no report on the _general_ market trends are going to cover every anecdote in the US. It could be that the staples you mentioned aren't affected to the same degree. How about your non-staples? How about cars? Houses? Vacation expenses?

In fact, your comment could be read as the exception that proves the rule: you haven't been affected by rising costs because you stick to staples and avoid "frivolous" purchases (that is, you live frugally, as suggested by the article).

Most of the references are not to actual price data, eg CPI basket of goods, so here is the actual link.

Energy stands out as actually being noteworthy, but is not discussed in the article compared to food, consumer goods. It is pretty inelastic for most people, especially gas/diesel.
