英国の2〜12歳児童39名の食事日記を分析し、雑食・菜食・ビーガン食の栄養素摂取とGHG排出量を比較。ビーガン食は雑食より46%低い排出量を示し、栄養面でも適切な計画で主要栄養素を満たせるが、亜鉛やヨウ素には注意が必要。
English
Analysis of 3-day food diaries from 39 UK children aged 2–12 compares omnivorous, vegetarian, and vegan diets on nutrient adequacy and greenhouse gas emissions. Vegan diets had 46% lower GHG emissions than omnivorous diets while meeting most nutrient needs with fortified foods and supplements, though zinc and iodine intake remained concerns.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
英国の児童データだが、食生活のGHG排出比較は日本企業のスコープ3算定や食品セクターのサステナビリティ報告にも示唆を与える。プラントベース食への移行が排出削減に寄与する可能性を示し、日本の食料戦略やSSBJに間接的に関連。
In the global GX context
This study provides direct evidence of trade-offs between diet type and GHG emissions, relevant for food companies facing ISSB/CSRD disclosure requirements on Scope 3 emissions from purchased goods. It supports the potential for dietary shifts to contribute to decarbonization targets and informs lifecycle assessment methodologies.
👥 読者別の含意
🔬研究者:Offers empirical comparison of nutrient and carbon metrics across diet types in children, useful for dietary guidelines and environmental lifecycle analysis.
🏢実務担当者:Food companies and school meal planners can use data to design lower-carbon menus that still meet nutritional standards for children.
🏛政策担当者:Informs policy on dietary guidelines and carbon labeling, supporting public health and climate goals simultaneously.
📄 Abstract（原文）
As plant-based (PB) diets become more common among UK children, understanding their nutritional adequacy and environmental impact is vital. This study addresses that lack of understanding through assessment of the nutrient content and greenhouse gas emissions for omnivorous, vegetarian, and vegan diets. A cross-sectional analysis was conducted using three-day weighed food diaries from 39 UK children aged 2-12 years (omnivore n = 15; and PB: vegetarian n = 11; vegan n = 13). Nutrients were analysed with and without supplementation using Nutritics software. GHG emissions were calculated at the ingredient level (kgCO₂e/day) and grouped by Eatwell Guide food categories. No dietary group met all nutrient reference values. Omnivores exceeded recommended intakes for saturated fat and free sugars while failing to meet the recommended intake for fibre, whereas PB children had intakes of these nutrients in the healthy range. PB diets were adequate in protein and vitamin B12 even in the absence of supplementation. Vegan children also met iron requirements from diet alone, whereas omnivore and vegetarian children did not meet iron targets without supplementation. Vitamin D intake was insufficient across all groups when supplements were excluded, with only vegan children achieving recommended levels through supplementation. Zinc requirements were met only by vegetarian children with the aid of supplements and were not met by vegan or omnivore children with or without supplementation. Iodine intake remained inadequate in vegan children even with supplementation. Mean daily greenhouse gas (GHG) emissions differed significantly between diet groups, with omnivores having the highest emissions, while vegans had the lowest emissions: 46% lower than omnivores, and 20% lower than vegetarians. Well-planned PB diets can meet most nutrient needs in UK children when supported by fortified foods and supplements, while substantially reducing dietary GHG emissions compared with omnivorous diets. Shifting away from animal protein and dairy provides an opportunity for improving both nutritional quality and environmental sustainability.
