What’s Behind the Price Fluctuations of 5 Common Grocery Items: NPR

Since the pandemic, food prices have been derailed.

COVID lockdowns forced people to eat at home more often, and in April 2020, food prices saw their biggest rise in decades, increasing 2.6% from the previous month.

Then, in 2022, food prices began another rise, as Americans with cash on hand returned to stores in large numbers and retailers struggled to meet pent-up demand. The food system faced other shocks that year, including a serious outbreak of bird flu and Russia’s invasion of Ukraine. Food prices increased by 11.4% in 2022 alone.

This period of dramatic food inflation has slowed in 2023, although prices have generally not returned to previous levels. Instead, food prices continued to rise, but at a slower pace, roughly in line with overall inflation.

“But the damage was done,” said Ricky Volpe, an agribusiness professor at Cal Poly San Luis Obispo. “Any inflation that is happening in grocery stores now is on top of these already very high prices, and consumers are very sensitive to that.”

President Trump has pledged to lower food prices during his second term. And while some products have become cheaper since Trump returned to office, overall food prices have increased on average. This is due to a number of systemic factors, from rising labor costs to tariffs to rising energy prices caused by the war with Iran.

However, if you zoom in on a single food, the story is often more complicated. Specific issues facing a crop, animal species or geographic region can influence the retail price halfway around the world. Sometimes the price of an item varies far beyond what inflation itself can explain, or the price falls while most other items tend to rise.

We’ve selected five everyday food items—ground beef, eggs, coffee, butter, and chocolate chip cookies—to explain the complex math behind what you pay at the grocery checkout.
