Current evidence suggests a link between red and processed meat consumption and the risk of various cancers and other health outcomes. Using national survey data from the Canadian Community Health Survey (CCHS)-Nutrition 2015, we aimed to model a dietary scenario to assess the potential effects of increasing the intake of currently consumed plant-based meat alternatives by 100% and decreasing the consumption of red and processed meat by 50% on the diet quality and nutrient intakes of Canadians (≥1 year). This dietary scenario had no significant impact on dietary energy intake ( > 0.05), but resulted in a significant increase in the dietary intakes of fibre, polyunsaturated fatty acids, magnesium, and dietary folate equivalents ( < 0.05). On the other hand, this dietary scenario was accompanied by a significant decrease in protein (from 77.8 ± 0.6 g to 73.4 ± 0.6 g), cholesterol, zinc, and vitamin B12 intake ( < 0.05). Further, based on Nutrient Rich Food (NRF) scores, the overall nutritional value of the simulated diet was higher than the baseline diet. Our modeling showed that the partial replacement of red and processed meat with plant-based alternatives improves overall diet quality but may adversely affect the intake of some micronutrients, especially zinc and vitamin B12.
目前的证据表明,食用红色肉类和加工肉类与各种癌症和其他健康结果之间存在关联。本研究使用加拿大社区健康调查(CCHS-营养 2015 年)中的全国调查数据,旨在构建一种饮食方案,以评估通过将目前食用的植物性肉类替代品的摄入量增加 100%并将红色和加工肉类的摄入量减少 50%对加拿大(≥1 岁)人饮食质量和营养素摄入量的潜在影响。这种饮食方案对膳食能量摄入没有显著影响(>0.05),但显著增加了膳食纤维、多不饱和脂肪酸、镁和膳食叶酸当量的摄入量(<0.05)。另一方面,这种饮食方案伴随着蛋白质(从 77.8 ± 0.6 g 降至 73.4 ± 0.6 g)、胆固醇、锌和维生素 B12摄入量的显著下降(<0.05)。此外,根据营养丰富的食物(NRF)评分,模拟饮食的整体营养价值高于基础饮食。我们的建模表明,用植物性替代品部分替代红色肉类和加工肉类可以提高整体饮食质量,但可能会对一些微量营养素的摄入产生不利影响,尤其是锌和维生素 B12。
