Oregon Tilth recognizes the importance of food quality as a core value of organic farming. The Organic Center’s State of Science Review (2005) highlights how organic practices may elevate antioxidant and polyphenol levels in foods – compounds linked to plant resilience, better flavor, longer shelf life, and potential human health benefits.
Research shows that antioxidants play a dual role: protecting plants from stress and pests, while also contributing to human health by reducing the risk of chronic disease.
Evidence suggests that organic farming methods, such as avoiding synthetic inputs and supporting healthy soil biology, can increase these beneficial compounds compared to conventional systems.
Organic practices may also better preserve antioxidants during storage and reduce risks such as mycotoxin contamination.
For Oregon Tilth, this science reinforces why organic systems matter beyond yield or input substitution. Organic farming supports natural plant defenses, enhances nutritional quality, and delivers foods that may offer more robust health-promoting properties.
Continued research into the biological mechanisms of antioxidants and the role of organic production is essential to strengthen both farmer practices and consumer understanding of organic food’s unique benefits.
