Like most things, the organic discussion raises multiple competing issues, including:
• Human health effects from pesticide, hormone, or antibiotic use (animals),
• Nutrient quality of the food itself (e.g., more protein, more Vitamin A),
• Environmental effects from agriculture,
• Issues related to supporting certain companies (“Big Ag” vs. local), and
• Socioeconomic factors like food accessibility via supply & cost.
And even within each of these issues, blanket consensus statements are difficult. For example, the idea that organic is always "healthier" based on nutrient composition is debatable (PMID: 31861431; PMID: 22944875). Especially once you look across all nutrients or calories. While some nutrients may be higher, scientists also acknowledge the lack of consistency and influence of factors like geographical area, crop type/species, and fertilization or tillage practices on their study findings (PMID: 24968103). As an example, the selenium content of corn in the United States can vary as much as 200-fold due to differences in soil levels (Willett, 2013 - Nutritional Epidemiology, 3rd Ed).
And of course, when we are talking about one's overall health - the influence of the whole diet matters. If your meat has more omega-3s, but you are eating too much fat overall, does it matter? If your grapes have more phenolics (anti-oxidants), but you are eating too many chips, does it matter? Likely not.
