I made a bit of list for you poor folks in USA likely to be hit by Trump's tariffs,
what I would personally prioritize getting in approximate order of necessity when economy dries up or prices gallop away:

rice (both whole grain/brown for fiber and nutrition while also white for ease of use and price)
dried/canned beans and similar (red/green lentils, kidney)
salt (essential for body)
cooking oil (canola)
canned tomatoes (base for many soups/sauces)
pasta (spaghetti, etc, preferably whole grain)
rolled oats (quick food with low own sugar)
low complexity sugar like dried fruits (raisins, date paste, dried apricots), plain sugar or honey
spices (peppers, dried granulated/powdered garlic, etc by taste, for morale)
nut butters (peanut, cashew, etc, quick high energy and protein)
canned/pickled veggies (choose by price and taste, for variety)
flours (if you plan on baking: also dried yeast)
coffee/tea (sometimes a pick-me-up is needed)
soaps (liquid, as generic as possible to enable same being used for body, floors, dishes, laundry)
multivitamins (to attempt compensating for potential lack of fresh veggies and variety) with in particular B12

I am NOT a doctor.
I have, however, gone 6 months on no income, then 6 again just after and had other similar experiences, sooo… I'm sharing my experience.

As economists and journalists I've seen so far have been just unable to find any real basis for Trump's claimed external tariffs being "responded to", mostly describing them with terms like "magic" or "apparently unfounded", here is the first person professionally within the relevant fields I've seen who claims to have a solid explanation for how the numbers were made, either astonishingly incompetently or more likely plain deceptively, from James Surowiecki (en.wikipedia.org/wiki/James_Su…).

White House Deputy Press Secretary Kush Desai claims that "No we literally calculated tariffs and non tariff barriers", while in its claims Trump-administration has reclassified EU's VAT (value-added tax) as a non-tariff barrier while that is just not true, VAT isn't a trade barrier but instead an evolved form of what in USA is "sales tax" mess which isn't mentioned in the other direction by Trump and representatives.

The exception seems to be when a place has no/very low trade with USA, so their crazy calculation can't be reasonably applied, they just declare 10% anyway, like e.g. Heard Island and McDonald Islands with population total of 0,
except for Russia which isn't included and they claim it's because Russia is sanctioned so trade is low, but that didn't stop them from putting other places on the list.

Again, import tariffs are not "paid by other countries", they are added to the thing's cost at the border, so unless some corporation decides to be nice and give of their profit margin (hah!) that means the tariff is aimed at the domestic populace and WILL disproportionately impact the low income people for whom the price increase will be a larger proportion of their meager income for things they can't just "deprioritize", like basic foods, while the opulent can just decide to buy a yacht fewer that year.

Long term, some production may move to surrender to Trump's aggression (horrible idea, considering Trump's instability) but for important stuff like food, time it would take to mass-establish new farms at required quantity is definitely more than one season (often = year) I'd say and in some cases some products just actually can not be produced in USA so in such cases the economic inflation was just drastically increased because Trump has more experience of bankruptcies than understanding of tariffs.

Local production IS good, environmentally, income equality, labor rights, etc, but it CAN NOT be implemented at immediate whim of a decree. It is just not even theoretically possible, even if everyone in the entire world wanted it, which due to Trump's rhetoric is absolutely not the case now.

I feel like a lot of people have misunderstood who is the initial and most harmed target of Trump's tariffshit.
It is not other countries. Other countries don't "pay tariffs" when it's USA's import tariffs.
It is only indirectly, secondarily corporations and they can move to avoid being targeted (absolutely shouldn't, because Trump is unreliable and if you give in to extortion...) or shift their focus domestically or at least outside USA.
That discourse focus is on this aspect is likely due to Trump's presentation as such but primarily because major news agencies, especially Reuters after being bought, has higher focus on finance-market news than on other news because finance-market organizations and gamblers pay more for news.

The initial and most impacted are instead the regular people in USA and the poorer the more impacted.
The tariffs are added to a product's cost at the border, so unless some corporation feels like decreasing their profit ≥10%, then the cost for the people inside USA will increase.
Most people can't just move to where they're not hit and can't just "focus" on elsewhere as corporations can.
The less income a person has, the more of their income goes to mandatory things like food, which they can't just deprioritize because much of it just isn't grown in USA so gets hit.

Remember when the WTO, which traditionally has been USA's enforcer to impose "free trade" beneficial to USA to the detriment of everyone else pretty much worldwide, when they in 2007 shocked the world by ruling for the little guy instead of for the abusive bully?
When they ruled that because USA had violated Antigua's free trade rights, therefore Antigua got the right to retaliate by ignoring "intellectual property" (allowed to "pirate" music, movies, software, etc) from USA at a total of up to $21 million a year (if not, here wto.org/english/tratop_e/dispu… reuters.com/article/technology… ya go)?
Well, Antigua apparently didn't what they were allowed to but instead wanted to just get reuters.com/article/us-usa-ant… paid, so USA just didn't pay, because bullying, but that's beside the point.

The point being... Hmm, wonder if something similar could be done related to Trump's current tariffshit?
I bet that if a whole bunch of ignoring the "intellectual property" of USA corporations would be actually made legal, for like $billions annually, in say for example all of the EU, then some very influential corporations and their bribery, uhmm, I mean lobbyists, would probably stop backing Trump's dragging USA down the drain of authoritarianism.
That would be interesting.

Because I had missed it, here for a more depressing-comedy-based coverage of Trump's tariffshit is the latest empisode of Last Week Tonight with John Oliver:
youtube.com/watch?v=5zQ0WewZY5…

The system they are describing as "decades and decades old" and similar has been imposed by primarily USA since 80 years, increasingly latest 60 years and very aggressively latest 30 years, specifically to force others to become producers lower paid producers with less labor, etc rights for the purpose through that exploitation generating more profits for USA-based multinational corporations while keeping on enabling the disproportionately luxurious median standard of living for people in USA but also enabling the further crushing of labor rights in USA and further impoverishment of the working class in USA,
which is why anarchists and other leftists militantly opposed the globalization with e.g. huge protests against WTO in Seattle 1999 (successfully en.wikipedia.org/wiki/1999_Sea…) and so very many others (e.g. en.wikipedia.org/wiki/Template…).
That globalization is still killing us, but a reversal even at collective global consensus full speed would take years instead of Trump's demanded hours to months and Trump's isn't intended to end globalization but will worsen exploitation of most impoverished, both at home and abroad.

We warned in the late 80s, peaking in the 90s, through the 00s but forced to prioritize more immediate disasters from the mid-10s, that the globalization which USA and marauders like Thatcher forced on the whole world was intended to let Capital and Capitalists move freely, to let corporations leverage the worse labor rights, environmental protections, authoritarianism, &c against the productive classes in both the "developed world" and the "developing" through moving production from the former to where wages were lower, unionizing persecuted, devastation ignored, with only the absolute top tier econo-political elite long-term winners as those kept collecting the profits regardless who was exploited, "the 1%", while the poor practically are prevented from the same, amplifying injustices.

We were obviously correct, as is plain to see now through the huge increasing gap between opulent few and everyone else, climate change, wars, cold war, lethal borders for poor while exceptions and private jets for rich.

Now they do the same pro-corporate, pro-elite leveraging of forced disastrously rapid change in other direction, combined with automation and "AI", leaving all except the extreme elite devastated again.

You should have listened.
Freedom for the people, not for exploitation against us all.

This is important.
As you have probably seen, yesterday the firmly reactionary and authoritarian, right-wing Ursula von der Leyen capitulated EU's economy to Trump's tariff extortion aggression, but most reporting only covers the tariffs themselves (highest in 70 years excepting Trump's initial assault) but neglect the absolutely devastating part that EU agreed to obligate itself to import habitat devastating fuels like fossil gas/oil for a value of $250 billion a year for three years!
As this reuters.com/business/energy/eu… economic analysis article shows, that is not just a habitat devastating increase, but "delusional [...] completely unrealistic and unachievable".

Then on top of that "a bilateral tariff exemption for [...] aircraft, EU chief Ursula von der Leyen said" lbcgroup.tv/news/world-news/86… which exempts the most polluting form of transport.

Then also, also, there is included an obligation to buy more weapons from USA, while demilitarization and deescalation is the only path to return to peace.

This rewarding of economic terror has now shown Trump that extortion pays, so WILL directly cause severe instability at the whims of the "very stable genius",
instead of standing firm until Trump has to give up.

This also threw all smaller countries, unable to resist as EU can, under the Trump train.
