含糖饮料 / 100% 果汁和吃水果一样

真相

喝下去的糖绕过饱腹感，热量只叠加不替代；每天一份含糖饮料，2 型糖尿病风险升 18%（校正体脂后 13%），果汁约 +5%（不显著），校正后 +7%（Imamura 2015，17 个队列，38,253 例）。

三条常见误区可以一次说清：喝果汁不等于吃水果；普通健身不需要靠运动饮料补水；无糖饮料也不是可以无限量喝的安全品。

Consumption of sugar sweetened beverages, artificially sweetened beverages, and fruit juice and incidence of type 2 diabetes: systematic review, meta-analysis, and estimation of population attributable fraction. BMJ, 351, h3576. 17 cohorts (38,253 cases; 10,126,754 person-years). Per serving a day: sugar-sweetened beverages +18% (+13% after adjusting for adiposity); artificially sweetened beverages +25% (+8%), with publication bias and residual confounding indicated; fruit juice +5% (non-significant) and +7% after adjustment. Population attributable fraction for SSB: 8.7% in the US, 3.6% in the UK (abstract, PMID 26199070).
Muraki, I., Imamura, F., Manson, J. E., Hu, F. B., Willett, W. C., van Dam, R. M., & Sun, Q. (2013). Fruit consumption and risk of type 2 diabetes: results from three prospective longitudinal cohort studies. BMJ, 347, f5001. Across 187,382 participants in three cohorts, higher whole-fruit intake was associated with lower type 2 diabetes risk while higher fruit-juice intake was associated with higher risk; substituting whole fruit for juice was associated with lower risk. Abstract figures (NHS, NHS II, HPFS; 12,198 cases): per 3 servings a week, whole fruit HR 0.98; blueberries 0.74, grapes and raisins 0.88, apples and pears 0.93, bananas 0.95, cantaloupe 1.10; fruit juice 1.08 (1.05-1.11).
