HVN1913 Metadata Record - Pasture-raised Advantage: the role of NZ pasture-raised red meat on nutrition, health and wellness in humans. PRotEin Diet SatisfacTION Trial 3 (PREDICTION)

This metadata record and it's attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.<b>Description:</b> Protein rich foods that are alternatives to farm-grown meat have received considerable consumer attention. Whilst meat alternatives were once niche food products aimed at vegetarians, they are increasingly marketed to omnivores and "flexitarians", thus contributing to a trend for reductions in red meat intakes. Studies to date have addressed the environmental benefit, plus consumer perceptions and acceptability of meat alternatives, yet there is surprisingly a paucity of data compared the nutritional and digestive differences to meat. The aim of this trial is to compare the digestive consequences of pasture-fed and grain-finished, beef versus a plant-based meat analogue blinded meal.Healthy, young (20-34 y) participants were asked to consume three separate meals in a crossover, blinded investigation followed by five hours of blood testing and questionnaires to assess the digestive consequences of meat and a plant-based meat analogue. The three meals included either pasture-fed, or grain-finished, or laboratory based protein alternative as a mixed meal, in random order, separated by one week minimum. Plasma samples were assessed for amino acid content, neurotransmitter proteins, chylomicron fatty acid distribution and general health indices.

本元数据记录及其附件说明了本研究收集的数据类型，并制定了当前及未来该数据的治理政策。<b>描述：</b>作为农场养殖肉类替代品的高蛋白食品受到了消费者的广泛关注。虽然肉类替代品曾是针对素食者的小众食品，但如今它们正越来越多地推向杂食者和“弹性素食者（flexitarians）”，从而推动红肉摄入量减少的趋势。迄今为止的研究探讨了肉类替代品的环境效益，以及消费者对其的认知和接受度，但令人惊讶的是，关于肉类替代品与肉类在营养及消化差异方面的数据却十分匮乏。本试验旨在比较草饲（pasture-fed）牛肉、谷饲育肥（grain-finished）牛肉与植物基肉类替代品（plant-based meat analogue）盲法餐食的消化结果。健康的年轻参与者（20-34岁）需在交叉盲法研究（crossover blinded investigation）中食用三种不同餐食，随后进行5小时的血液检测和问卷调查，以评估肉类与植物基肉类替代品的消化结果。这三种餐食包括草饲牛肉、谷饲育肥牛肉或实验室制备的蛋白质替代品混合餐，按随机顺序食用，间隔至少一周。血浆样本将检测氨基酸含量、神经递质蛋白、乳糜微粒脂肪酸分布及一般健康指标。
