Food has a considerable environmental impact. Diets with less meat and dairy reduce environmental impact but may pose nutritional challenges for children. The current modelling study investigates the impact of diets with less or no meat and dairy products on nutrient intakes.
Energy and nutrient intakes were assessed for observed consumption patterns (reference) and two replacement scenarios with data from the Dutch National Food Consumption Survey - Young Children (2005-2006). In the replacement scenarios, 30 % or 100 % of the consumed dairy and meat (in grams) was replaced by plant-derived foods with similar use.
The Netherlands.
Children (n 1279) aged 2-6 years.
Partial and full replacement of meat and dairy foods by plant-derived foods reduced SFA intake by 9 % and 26 %, respectively, while fibre intake was 8 % and 29 % higher. With partial replacement, micronutrient intakes were similar, except for lower vitamin B12 intake. After full meat and dairy replacement, mean intakes of Ca, Zn and thiamin decreased by 5-13 %, and vitamin B12 intake by 49 %, while total intake of Fe was higher but of lower bioavailability. With full replacement, the proportion of girls aged 4-6 years with intakes below recommendations was 15 % for thiamin, 10 % for vitamin B12 and 6 % for Zn.
Partial replacement of meat and dairy by plant-derived foods is beneficial for children's health by lowering SFA intake, increasing fibre content and maintaining similar micronutrient intakes. When full replacements are made, attention is recommended to ensure adequate thiamin, vitamin B12 and Zn intakes.
食物对环境有相当大的影响。减少肉类和奶制品摄入的饮食可降低对环境的影响,但可能给儿童带来营养方面的挑战。当前的模型研究调查了减少或不摄入肉类和奶制品的饮食对营养摄入的影响。
利用荷兰全国儿童食品消费调查(2005 - 2006年)的数据,对观察到的消费模式(参考)以及两种替代方案的能量和营养摄入量进行评估。在替代方案中,30%或100%的消费奶制品和肉类(以克计)被类似用途的植物性食物替代。
荷兰。
2至6岁的儿童(n = 1279)。
用植物性食物部分和完全替代肉类和奶制品,分别使饱和脂肪酸(SFA)摄入量降低了9%和26%,而膳食纤维摄入量分别提高了8%和29%。部分替代时,除维生素B12摄入量较低外,微量营养素摄入量相似。完全替代肉类和奶制品后,钙、锌和硫胺素的平均摄入量下降了5% - 13%,维生素B12摄入量下降了49%,而铁的总摄入量较高但生物利用度较低。完全替代时,4至6岁女孩中硫胺素、维生素B12和锌摄入量低于推荐值的比例分别为15%、10%和6%。
用植物性食物部分替代肉类和奶制品有利于儿童健康,可降低饱和脂肪酸摄入量、增加膳食纤维含量并维持相似的微量营养素摄入量。当进行完全替代时,建议注意确保硫胺素、维生素B12和锌的充足摄入。
