Typically 1 to 3 times the price of regular versions of the same foods.
When we combine 17 studies done on humans with 223 studies analyzing food composition, there’s no solid evidence that organic food is significantly more nutritious. Only 3 of those studies actually looked at health outcomes after people ate it, and no difference was found between organic and conventional foods. The proportion of organic produce found to contain pesticide residues is indeed 30 percentage points lower, but detection does not mean those levels exceed safety limits. Eating more fruits and vegetables is beneficial regardless of whether they’re organic or not.

9. Don’t pay a premium for organic food just to be “healthier”
Cost: Typically 1 to 3 times the price of regular versions of the same foods.
In plain terms: When we combine 17 studies done on humans with 223 studies analyzing food composition, there’s no solid evidence that organic food is significantly more nutritious. Only 3 of those studies actually looked at health outcomes after people ate it, and no difference was found between organic and conventional foods. The proportion of organic produce found to contain pesticide residues is indeed 30 percentage points lower, but detection does not mean those levels exceed safety limits. Eating more fruits and vegetables is beneficial regardless of whether they’re organic or not.
Benefit: One systematic review brought together 17 human studies and 223 studies on food composition. Its conclusion: “There is insufficient evidence to show that organic food is significantly more nutritious than conventional food.” Again, only 3 studies examined health effects after consumption (looking at allergies and symptomatic infections), and no meaningful difference emerged. Organic produce shows a 30 percentage point reduction in pesticide residue detection rates, though detection alone does not indicate unsafe levels. The perception that organic food is a better buy stems from the common-sense chain: “no pesticides = safer = healthier.”
Evidence grade: B
Sources: Smith-Spangler C et al. (2012). Are organic foods safer or healthier than conventional alternatives?: a systematic review. Ann Intern Med. <https://doi.org/10.7326/0003-4819-157-5-201209040-00007>
Notes: Very few studies directly assess health outcomes after human consumption. Therefore, this finding means “there’s no evidence it’s better,” not “it’s been proven to offer no benefits.” This analysis does not address environmental impact, animal welfare, or taste preferences. Eating more fruits and vegetables remains beneficial regardless of whether they’re organic or not.

9. 不要为了「更健康」花溢价买有机食品
成本: 一般是同类普通食品价格的 1 到 3 倍。
说人话: 没有有力的证据说有机食品更有营养。真正看了人吃完以后健康怎么样的研究只有 3 项，都没看出差别。有机农产品被检出农药残留的比例确实低 30 个百分点，但检出不等于超标。多吃蔬菜水果本身有用，是不是有机的不影响这一点。
收益: 有一篇系统综述，把 17 项在人身上做的研究和 223 项测食品成分的研究合起来看。结论是「缺乏有力证据表明有机食品比常规食品显著更有营养」。这里面只有 3 项研究看的是人吃了以后健康怎么样（看的是过敏和有症状的感染），两边没看出差别。有机农产品被检出农药残留的比例低 30 个百分点，但检出不等于超标。它看起来划算，是因为「没农药就更安全，更安全就更健康」，每一步听上去都像常识
证据等级: B
来源: Smith-Spangler C et al. (2012). Are organic foods safer or healthier than conventional alternatives?: a systematic review. Ann Intern Med. <https://doi.org/10.7326/0003-4819-157-5-201209040-00007>
备注: 直接看人吃了以后健康怎么样的研究非常少。所以结论是「没有证据说它更好」，不是「已经证明它没好处」。对环境的影响、动物福利、口味好不好，这里不管。多吃蔬菜水果本身有效，是不是有机的不影响这一点
