最近的研究表明，美国肥胖人数的急剧上升更多是由于过度消费不健康食品，而不是运动不足。这项研究测试了对食物营养的成瘾，作为明显过度消费的潜在解释。采用随机系数（混合）logit模型对多元理性成瘾模型进行检验。研究结果显示，人们对碳水化合物的依赖性特别强。这一发现的含义是，以价格为基础的政策、税收或生产补贴，改变消费碳水化合物密集型食品的预期未来成本和收益，可能有效地控制过量的营养摄入。
Recent research shows that the dramatic rise in obesity in the United States is due more to the overconsumption of unhealthy foods than underactivity. This study tests for an addiction to food nutrients as a potential explanation for the apparent excessive consumption. A random coefficients (mixed) logit model is used to test a multivariate rational addiction model. The results reveal a particularly strong addiction to carbohydrates. The implication of this finding is that price-based policies, sin taxes, or produce subsidies that change the expected future costs and benefits of consuming carbohydrate-intensive foods may be effective in controlling excessive nutrient intake.
