科学评估
正确 – 该说法有可靠证据支持。
证据确定性: 中 – 进一步研究仍可能影响该评估。
1. 说法是什么？
High-nitrate vegetables can poison young infants.
2. 哪些内容可证实是正确的？
Correct: two infants (1 and 2 months) developed methaemoglobinaemia of 30.4% and 27% after formula reconstituted with concentrated courgette soup; AAP notes continued reports from home-prepared vegetable foods. A Spanish series of 78 infant cases found that purees prepared more than 24 hours in advance (OR 17.4-24.9) and very high-nitrate leaves (borage, chard) were the main risk factors (Martinez 2013, I-VEG-113); an Italian series found badly preserved vegetable broth as the main cause in weaning infants (median age 8 months; Raucci 2022, I-VEG-114). EFSA (2010, I-VEG-115) could not exclude a risk for some infants eating more than one spinach meal a day and warned about storage of cooked vegetables.
3. 哪些内容是错误或夸大的？
The archive uses an infant-specific risk as an argument against greens for everyone. Paediatric guidance recommends offering vegetables, including bitter green vegetables, from 4-6 months (ESPGHAN 2017, I-VEG-111).
4. 哪些内容仍不明确？
Not applicable.
5. 哪些研究支持该说法？
Savino 2006; Greer 2005; EU Reg. 2023/915 (200 mg/kg limit for baby foods).
6. 哪些研究与该说法相矛盾？
None for infants.
7. 对德国和欧洲而言情况如何？
EU Regulation 2023/915 sets 200 mg NO3/kg for baby food and processed cereal-based food.
8. 关于埃及的已知情况是什么？
Home-prepared vegetable broths for very young infants are a relevant practice to warn about.
9. 合理的实际结论是什么？
不要给出生后头几个月的婴儿喂自制的高硝酸盐蔬菜汤（菠菜、莙荙菜、甜菜、琉璃苣、西葫芦），也不要把自制的蔬菜泥或蔬菜汤存放一天或更久（应现做或冷冻）；从约 4-6 个月起，蔬菜仍是推荐的辅食。

总体证据说明了什么？
基于上述研究的编辑评估——其本身并非研究结果。
哪种观点有更好的证据支持？
True for infants: nitrate-rich vegetable broths or purees, especially when stored for a day or more, can cause methaemoglobinaemia, mostly in the first year of life. Freshly prepared or frozen vegetables remain recommended in complementary feeding from about 4-6 months.
为什么有些研究权重更大
Consistent case series from several countries, a case-control analysis, an EFSA statement and an AAP clinical report agree; no evidence contradicts the infant risk.
因果关系是否已确立？ 是，已确立 Mechanism (nitrate to nitrite, oxidation of haemoglobin, low infant MetHb reductase) and repeated temporal cases with nitrite measurement.
仍存在的不确定性
Incidence per exposed infant.
合理的结论
True for infants under the stated conditions; not an argument against vegetables for older children or adults.
为什么研究结果看起来互相矛盾？
Not a conflict: ESPGHAN recommends green vegetables from 4-6 months, while case series show harm mainly from stored or concentrated broths and very high-nitrate leaves; the conditions differ (age, preparation, storage).
这是否取决于国家？
- 一般生物学效应
- Infant physiology is universal.
- 饮食习惯
- Home-made vegetable broths for infant constipation or weaning are common in Egypt and Mediterranean countries.
- 食品原产地
- Nitrate content depends on fertilisation, season and light; EU sets limits for baby foods.
- 污染物
- Not a contaminant issue; natural nitrate accumulation.
- 本国生产条件
- Egyptian nitrate data in leafy vegetables were not reviewed.
- 法律规则
- EU Reg. 2023/915 (I-VEG-14) limits nitrate in baby foods to 200 mg/kg.
- 实际监测数据
- not reviewed
足以改变结论的地区差异没有可靠数据支持。

通俗解释
很小的婴儿如果吃了用西葫芦或菠菜等富含硝酸盐的蔬菜自制的汤，可能会患上一种危险的血液疾病（高铁血红蛋白血症）。这一点有充分记录。它适用于出生后头几个月的婴儿，而不适用于较大的儿童或成人。
