Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.
In this episode, we cover: •[00:00] Introduction •[01:19] Rodolphe Barrangou explains the potential opportunities and challenges for plant-based meat alternatives to help mitigate the environmental impact of meat. •[03:18] Marco Springmann compares plant-based meat and milk alternatives with both animal-sourced foods and unprocessed plant-based foods across multiple metrics. •[05:16] Bill Aimutis highlights the potential environmental impact of producing plant-based proteins. •[07:04] Ute Weisz finds significant variability in the amino acid scores and functional properties of commercially available plant protein ingredients. •[08:51] Zachary Neuhofer analyzes trends in plant-based meat alternative consumption, based on two years of grocery store scanning data. •[10:16] Evelyne Selberherr analyzes the microbial communities found in plant-based meat alternative products. •[11:56] Matin Qaim analyzes the impact of animal-sourced foods on child nutrition in five Sub-Saharan African countries. •[13:59] Final thoughts and conclusion.
