This study provides an overview of the ingredients, origin, processing level, nutritional quality and practitioners' insights of commonly used meat substitutes in Swedish school meals. Using quantitative and qualitative data, this study evaluated 59 meat substitutes from 19 brands using Percentage Nutrient Contribution (%NC) to a Swedish school meal based on 30% of the recommended and maximum nutrient intake for teenagers and the NOVA processing framework. Meat substitutes were mince, balls, breaded, burgers, strips, or sausages. Interviews with meal planners ( = 7) revealed experiences with meat substitutes in schools. Most meat substitutes (86%) were classified as ultra-processed foods, with low contributions to saturated fat and free sugars, but high contributions to fibre and salt intakes. Limited micronutrient data suggested significant contributions of potassium, folate, and iron. Meal planners chose meat substitutes for climate reasons, familiarity, and acceptability. Meat substitutes have potential, but processing effects, bioavailability and fortification require further research.
本研究概述了瑞典学校餐中常用肉类替代品的成分、来源、加工水平、营养质量和从业者的见解。本研究使用定量和定性数据,根据青少年推荐和最大营养素摄入量的 30%以及 NOVA 加工框架,对 19 个品牌的 59 种肉类替代品进行了评估。肉类替代品包括肉末、肉丸、面包屑、汉堡、条状物或香肠。对膳食计划者(n=7)的访谈揭示了学校中肉类替代品的使用经验。大多数肉类替代品(86%)被归类为超加工食品,对饱和脂肪和游离糖的贡献较低,但对纤维和盐的摄入量贡献较高。有限的微量营养素数据表明钾、叶酸和铁的摄入量有显著贡献。膳食计划者出于气候原因、熟悉程度和可接受性选择肉类替代品。肉类替代品具有潜力,但加工效果、生物利用度和强化仍需要进一步研究。
