How 10 everyday grocery staples are sourced, sold and used in the U.S.

A look at what Americans buy at the grocery store, from bananas and eggs to coffee and tomatoes, and how 10 everyday staples are produced and sold

A grocery receipt works like a short report on the global economy. The bananas in a typical cart most likely came from Central or South America. They are imported and sold year-round. The coffee was almost certainly imported. Commercial coffee growing in the U.S. is limited to Hawaii, plus small amounts in California and Puerto Rico. A carton of eggs can reflect events on poultry farms in other states.

Outbreaks of highly pathogenic avian influenza in laying flocks drove sharp increases in egg prices in 2022 and again in early 2025. A disease in hen houses showed up at the checkout. Other shifts happen over decades rather than months. USDA data show that per-person fluid milk consumption in the U.S. has fallen over several decades. Cheese and yogurt have gained ground over the same stretch.

The list of what Americans buy at the grocery store reflects how households cook, eat and spend. The 10 items here are a selection of everyday staples, not a sales ranking. They come from nearly every part of a supermarket. The produce section supplies bananas and fresh tomatoes. The dairy case holds milk and eggs. The bread aisle stocks sliced sandwich bread, and the meat counter offers chicken and ground beef.

The center aisles fill out the rest of the list. They carry carbonated soft drinks from brands such as Coca-Cola $KO 0.64%, Pepsi and Dr Pepper $DPS. Nearby sit potato chips, tortilla chips, pretzels and popcorn, including Frito-Lay brands such as Lay's and Doritos. Coffee appears in three forms for home brewing: ground, whole bean and single-serve pods.

Each slide covers one staple and how it is sourced, sold and used. Some come with a documented history. Pre-sliced bread was first sold commercially in 1928 by the Chillicothe Baking Company in Chillicothe, Missouri. In 1893, the U.S. Supreme Court ruled in Nix v. Hedden that tomatoes count as vegetables for tariff purposes. Botanists classify them as fruit. Labels carry information too. A package of ground beef marked 80/20 or 90/10 states its lean-to-fat ratio. Chicken reaches stores as boneless skinless breasts, thighs, drumsticks, wings and whole birds. Readers curious about what fills the average American grocery cart will find many familiar items here, with the context behind them.

Bananas from Central and South America

Bananas are the fresh fruit Americans eat the most of by weight per person, according to the U.S. Department of Agriculture, which has tracked that pattern for many years. Most of the bananas in U.S. stores arrive by ship from Central and South America.

Guatemala, Ecuador, Costa Rica, Honduras and Colombia are among the major suppliers to the U.S. market. Growers in the tropics can harvest bananas year-round. That steady harvest means the produce counter has no banana off-season.

Nearly every banana in a U.S. supermarket is a Cavendish. That variety replaced the Gros Michel, which led the export trade until Panama disease wiped out plantations in the mid-20th century. Panama disease is caused by a soil fungus. A newer strain of the same fungus, known as Tropical Race 4, now affects Cavendish plants in parts of Asia, Africa, Australia and Latin America. Commercial bananas are grown from clones rather than seeds. As a result, the plants share the same genetic weaknesses.

Bananas are picked green, not ripe. They travel north in refrigerated shipping containers. Distributors then place them in ripening rooms and expose them to ethylene, a gas the fruit also produces on its own. The gas starts the shift from green to yellow. This timed process lets retailers stock bananas at different stages of ripeness.

At the store, bananas are usually priced by the pound, though some retailers charge per banana. They are sold in clusters called hands. A single banana is called a finger. Large importers include Chiquita, Dole and Fresh Del Monte, and their brand stickers appear on much of the fruit.

Ripening continues at home. At room temperature, a banana moves from green-tipped to yellow to brown-spotted over several days. A refrigerator turns the peel dark but slows the softening of the fruit inside. Sealing bananas in a paper bag traps ethylene and speeds ripening.

Overripe bananas are a common base for banana bread, and frozen slices often go into smoothies. Bananas supply potassium and vitamin B6. The fruit is botanically a berry, and the plant that bears it is a giant herb rather than a tree.

Eggs and the bird flu price swings of 2022 and 2025

Egg prices in the U.S. rose sharply in 2022 and climbed again in early 2025. In both periods, the main driver was highly pathogenic avian influenza spreading through commercial flocks of laying hens.

The virus behind the outbreaks is the H5N1 strain of avian flu. Wild migratory birds, especially ducks and other waterfowl, carry it and can pass it to domestic poultry. U.S. animal health policy calls for an entire flock to be culled once a bird in it tests positive. The goal is to keep the disease from spreading to neighboring farms.

Large egg farms often house hundreds of thousands of hens at a single site. One positive test can take a large volume of production offline at once. Rebuilding that supply takes months. Farms must clean and disinfect their barns before restocking. New hens, known as pullets, generally begin laying at about five months old.

U.S. supermarkets sell eggs from the refrigerated case because of how they are processed. Commercial eggs in the U.S. are washed before packing. Washing removes a thin natural coating on the shell called the cuticle. Federal rules require shell eggs to be held at 45 degrees Fahrenheit or below. In the U.K. and much of the European Union, eggs are generally not washed. Shoppers there often find them on unrefrigerated shelves.

Cartons carry several pieces of information. USDA grades of AA, A and B reflect interior quality and shell condition. Size names such as jumbo, extra large, large and medium are based on the minimum weight of a dozen eggs. Cartons with the USDA grade shield also print a pack date as a three-digit number for the day of the year.

Labels such as cage-free, free-range and pasture-raised describe how........
