Chronic illness is a global epidemic and places significant economic and social burdens on societies. Research has shown that a healthy diet can be used to mitigate or significantly reduce the risk of many chronic illnesses. Health authorities around the world have begun regulating health claims on foods to encourage the consumption of healthy foods. However, the “ex post” efficacy of health claims regulations on consumers demand for healthy foods has not been assessed. The demand for fats and meats in Canada is estimated using a linear‐approximate almost ideal demand system. The results indicate health claims decreased unhealthy food demand between 1.41% and 7.10% and increased healthy food demand between 1.95% and 8.50%.

健康声称是否影响了加拿大对脂肪和肉类的需求？

慢性病是一种全球流行病，给社会带来了巨大的经济和社会负担。研究表明，健康饮食可以用来减轻或显着降低许多慢性病的风险。世界各地的卫生当局已开始规范食品的健康要求，以鼓励食用健康食品。但是，尚未评估健康声明法规对消费者对健康食品需求的“事后”功效。加拿大对脂肪和肉类的需求是使用线性近似，几乎理想的需求系统估算的。结果表明，健康声称减少了不健康食品需求的1.41％至7.10％，并增加了健康食品需求的1.95％至8.50％。
