Study TitleA metabolomics comparison of plant-based meat and grass-fed meat indicates large nutritional differences despite comparable nutrition facts labels
Study SummaryA new generation of plant-based meat alternatives—formulated to mimic the taste and nutritional composition of red meat—have attracted considerable consumer interest, research attention, and media coverage. This has raised questions of whether plant-based meat alternatives represent proper nutritional replacements to animal meat. Given that food sources have considerable complexity and contain a wide variety of nutrients (e.g., phenols, anti-oxidants, peptides, amino acids, fatty acids, and other carboxylic acids), the majority of which do not appear on nutrition labels, it is important to explore expanded nutrient profiles when determining whether beef and plant-based meat alternatives are nutritionally interchangeable. Important nutritional differences may exist between beef and novel plant-based alternatives, given their materials origin; however, this has not been thoroughly assessed. Given the scientific and commercial interest in plant-based meat alternatives, the goal of our study was to use untargeted metabolomics to provide an in-depth comparison of the metabolite profiles of grass-fed ground beef and a popular plant-based meat alternative.
