A wave of consumer discontent appears to have helped lift him back into the Oval Office, but Trump now faces the task of how to ease voters' frustration.
Food inflation soared to a peak of more than 10% in 2022, but price increases have slowed to about 2%, U.S. Bureau of Labor Statistics data shows.
Still, the yearslong bout of rapid inflation has sent food prices soaring more than 25% since President Joe Biden took office.
Typically, prices do not fall across the board unless the economy slows or even tips into recession, which would reduce consumer demand but also impose economic hardship, some economists told ABC News.

Still, Trump could enact policies that may slow the rise of grocery prices, or even lower the cost of some household staples, economists added.
"Prices on different items absolutely could come down," Michael Faulkender, a professor of finance at the University of Maryland's Robert H. Smith School of Business, told ABC News.
In response to ABC News' request for comment, the Trump transition team said in a statement that Trump intends to fulfill the commitments he made during the campaign. But the transition team did not specifically address the issue of grocery prices.
"The American people re-elected President Trump by a resounding margin giving him a mandate to implement the promises he made on the campaign trail. He will deliver." Karoline Leavitt, a spokesperson for the transition team, told ABC News.
Increase oil production
On the campaign trail, Trump often responded to concern about prices with a three-word mantra: "Drill, baby, drill."Trump, who has downplayed human-caused climate change, vowed to bolster the oil and gas industry by easing regulation and expanding output.
In theory, increased oil production could lower food prices since gas makes up a key source of costs throughout the supply chain, whether a firm is growing crops or transporting them to a seller, economists said.
"Energy is a big input cost for food," David Andolfatto, an economist at the University of Miami, told ABC News. "That should put downward pressure on food prices."
While such a move could prove beneficial, increased oil output under President Joe Biden coincided with the surge of inflation in recent years. Since oil is sold on a global market, a surge in domestic production may not lower prices for U.S. consumers as much as some may expect.
The U.S. set a record for crude oil production in 2023, averaging 12.9 million barrels per day, according to the U.S. Energy Information Administration, a federal agency.
A further uptick in oil production risks accelerating the nation's carbon emissions and worsening the impact of climate change, which would carry costs down the road, Luis Cabral, a professor of economics at New York University, told ABC News.
"We can't simply look at the benefits," Cabral said, acknowledging the potential for lower food prices. "There are also important costs in terms of emissions and climate change."
Bolster antitrust enforcement
To address high food prices, the Trump administration could crack down on market concentration, a term economists use to describe the dominance of a given industry by a handful of firms, some experts said.They pointed to the market power of large corporations as a cause of rapid price increases, saying companies use their outsized role in the market to raise prices without fear of a competitor offering a comparable product at a more affordable price.
"Whenever there are fewer players in an industry, prices tend to be higher," Cabral said. "Supermarkets aren't an exception."
Grocery store profit margins surged in 2021 and rose even higher two years later, even after price increases had begun to cool, a Federal Trade Commission study in March showed.
In February, the Federal Trade Commission sued to block the merger of supermarket chains Kroger and Albertsons, which would amount to the largest supermarket merger in U.S. history. The proceedings are ongoing, and will likely stretch into the Trump administration.
Some economists cast doubt over the potential benefits of antitrust, saying the recent bout of inflation coincided with an uptick in production costs during the pandemic. "It's hard to argue that it's therefore some kind of profiteering," Faulkender said.
Price-gouging ban
During the campaign, Vice President Kamala Harris proposed a federal ban on price gouging for food and groceries.The plan could resemble price-gouging bans in place in 37 states, which prohibit a sudden spike in prices for scarce goods, the Harris campaign said. Those bans prohibit companies from exploiting a sudden imbalance between supply and demand by significantly hiking prices.
While Trump may be reluctant to adopt a policy put forward by his proponent, he could advance a price-gouging ban as a means of preventing acute price increases for specific goods.
For instance, egg prices have skyrocketed 30% over the year ending in October, U.S. Bureau of Statistics data on Wednesday showed. The spike owed primarily to an avian flu outbreak that has decimated supply. Last year, egg prices climbed more than 60% in response to a similar avian flu outbreak.
Economists who spoke to ABC News differed on the effectiveness of a potential price-gouging ban.
Some economists dismissed the policy as a flawed solution, since state-level bans usually get triggered only in the case of emergencies and, even then, often lack clarity about the type of company behavior that constitutes price-gouging.
"I don't think a federal price-gouging ban would help at all," Cabral said.
Andolfatto, of the University of Miami, said a price-gouging ban could lower food prices if it barred rapid price increases under some circumstances. However, those benefits may be outweighed by the downside, since such a ban could override the market signal delivered by prices, which help direct the distribution of goods to places where they are in short supply.
"These types of interventions have unintended consequences," Andolfatto said.
