科学评估
可能正确 – 有一些证据支持该说法，但不足以得出明确判断。
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？
Food is the primary cause of modern diseases.
2. 哪些内容可证实是正确的？
Diet is among the leading risk factors for chronic disease: GBD 2017 attributed 11 million deaths (22% of adult deaths) to dietary risks (I-SYS-01); in GBD 2019 and 2021 dietary risks remained a leading Level 2 cluster (I-SYS-02, I-SYS-101), and diet also raises blood pressure, BMI and blood glucose, which are counted separately.
3. 哪些内容是错误或夸大的？
'First cause' is not supported by the newest analyses: in GBD 2021 the leading single risks were particulate air pollution (8.0% of DALYs), high systolic blood pressure (7.8%) and smoking (5.7%), and dietary risks ranked fifth among Level 2 clusters (I-SYS-101); in GBD 2023 high blood pressure, air pollution, high fasting glucose and smoking led (I-SYS-102). In a large UK cohort, smoking, socioeconomic factors and physical activity were the strongest drivers of mortality (I-SYS-103). The dietary risks that matter most (high sodium, low whole grains and fruit; I-SYS-01) are not those the system emphasises.
4. 哪些内容仍不明确？
Ranking diet vs blood pressure overlaps because diet contributes to blood pressure.
5. 哪些研究支持该说法？
6. 哪些研究与该说法相矛盾？
7. 对德国和欧洲而言情况如何？
Same global evidence.
8. 关于埃及的已知情况是什么？
Same.
9. 合理的实际结论是什么？
饮食是预防慢性病的一个重要手段，同时还需要不吸烟、控制血压、清洁空气、身体活动和限制饮酒。
评估详情
- 证据确定性的依据
Moderate: GBD 2017 ranked suboptimal diet first (22% of adult deaths; I-SYS-01), but the newer GBD rounds rank it lower - third (males) and second (females) for deaths and fifth for DALYs in GBD 2019 (I-SYS-02), fifth Level 2 risk for DALYs in GBD 2021 (I-SYS-101), with high systolic blood pressure, air pollution, high fasting glucose and smoking as leading single risks in GBD 2023 (I-SYS-102). Diet partly acts through blood pressure, BMI and glucose, so its total role is larger than its separate rank.

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？
Diet is one of the leading modifiable risk clusters for non-communicable disease and contributes to high blood pressure, glucose and BMI, but in the newest global analyses it is not the single first cause; air pollution, high blood pressure and tobacco rank higher.
为什么有些研究权重更大
Newer GBD rounds (2019, 2021, 2023) supersede GBD 2017 and consistently rank diet below blood pressure and tobacco; mediation means diet's total role is larger than its separate ranking.
因果关系是否已确立？ 很可能 Causal evidence for many dietary risks is from cohorts and some RCTs (e.g. sodium); weaker than for tobacco.
仍存在的不确定性
Ranking depends on how risks are grouped and on mediation assumptions.
合理的结论
Food is a leading cause of modern diseases, but calling it 'the first cause' overstates current evidence.
为什么研究结果看起来互相矛盾？
GBD 2017 (diet first) vs GBD 2019-2023 (diet second to fifth) differ because of updated relative risks and TMRELs (diet burden revised 29.7% downward) and different grouping levels; not a contradiction in data quality.

Verdict changed from MOSTLY_TRUE to POTENTIALLY_TRUE. The earlier verdict relied mainly on GBD 2017, which ranked diet first. The two newer GBD rounds (2021, I-SYS-101; 2023, I-SYS-102), together with GBD 2019 (I-SYS-02), consistently rank high blood pressure, air pollution and tobacco ahead of diet, and an exposome study (I-SYS-103) identifies smoking, socioeconomic status and activity as the strongest drivers. Diet remains a leading, partly upstream cause, so the claim is partly true but 'first cause' is overstated.

通俗解释
该档案网站说，食物是现代疾病的首要原因。食物确实是最重要的原因之一，一项较早的全球研究也曾把它排在第一位。但同一项目的较新更新把高血压、空气污染和吸烟排得更靠前，饮食位列前五——不过饮食本身也会升高血压和血糖。最重要的饮食问题是盐吃得太多，以及全谷物和水果吃得太少。

可能正确 不良饮食是慢性病的主要原因之一，但最新的全球分析把高血压、空气污染和烟草排在它之前，因此“首要原因”的说法超出了证据所能支持的程度。
该说法涉及生物学或医学关系。上述科学评估不论在哪个国家都适用；各国食品数据不会改变这一评估。
