In 1962, Rachel Carson published Silent Spring, in the book she highlights the issues regarding modern farming practices (3). By 1970, consumers began to show an interest in organic food as awareness of the negative effects on the environment grew (3). 

The organic industry has grown remarkably in the subsequent decades. There was an average increase of 8 percent per year in U.S. retail sales in the past decade (4). Price premiums have pushed U.S. organic production, as organic products generally sell for higher prices when compared to conventional products (5). Price premiums have contributed to conventional farmers transitioning to organic farming to increase returns (5). The growth of the industry is also driven by consumer interest. Some consumers choose organically produced food due to perceptions of better animal welfare, the environment, and health (4). 

Before products can be labeled USDA organic, specific requirements must be verified by a USDA-accredited certifying agent (6).   

To have an organic product, agricultural production practices must conserve biodiversity, minimize the use of synthetic materials, foster resource cycling, promote ecological balance, and maintain and improve soil and water quality (7). Three main practices include: 

• Follow all USDA organic regulations overseen by the National Organic Program (NOP)-authorized certifying agent.
• Produce products without sewage sludge, genetic engineering, ionizing radiation, and other prohibited methods.
• Produce organic products only using allowed substances

In 2002, the USDA established the National Organic Program to handle compliance with regulations for all organic agricultural products sold, labeled, or represented as organic (5). Only authorized foods that meet organic standards can display the USDA organic label. The Organic food seal is a registered trademark that allows the USDA to pursue legal actions against operations that falsely use the label (1). Yearly, organic farms and businesses must confirm they meet standards, including unannounced inspections conducted by USDA-accredited inspectors (1).

A term that may seem similar to the organic label is “natural” as it refers to products for which artificial ingredients are not added during the processing (13). When companies feature this label, consumers may be misled into thinking all inputs and methods used during production are natural or minimally processed (13).

 

 

Nutritional Differences 

There are no clear nutritional differences between organic food and conventional food, as nutritional and residual superiority depend on the food comparisons. For instance, a systematic review from 2024 analyzed 147 studies looking at micronutrients in organic and conventional fruits and vegetables. It was noted that organic products had higher levels of vitamin C, magnesium, and potassium however, conventional products had higher manganese content (11). This highlights the lack of a consistent nutritional advantage for either organic or conventional fruits and vegetables. 

Cost for Consumers

A study conducted by the USDA compared prices from 2010 of conventional and organic produce. The organic price was higher for all 18 produce items analyzed, with 17 products having the premium be more than 20 percent (14). In 2025, researchers analyzed the cost difference between organic and conventional fruits and vegetables, concluding that organic fruits and vegetables cost an average of 50% more than conventional (15). 

Comparing the percent differences of apples, carrots, and celery between 2010 and 2025, there is a substantial difference. The outlier was spinach with organic spinach dropping in price below conventional in 2025. The increase in price differences emphasizes a disparity in affordability between conventional and organic produce. Although consumers have shown a willingness to pay higher prices for organic products (4). This price gap highlights a concern for consumers with low income, who may not be able to afford these products. A 2022 meta-analysis found that consumers with a low income were less likely to develop a favorable attitude and less motivated to buy organic foods because of their circumstances (16).
