This paper presents a comprehensive comparison of the bioavailability of protein, vitamins (A, D, and B12), and key minerals (iron, zinc, and calcium) from animal-source foods (ASF) and plant-based alternatives. Based on the literature indexed in the Web of Science, Scopus, PubMed, and ScienceDirect databases, this review assessed nutrient absorption and matrix effects, including both antinutritional factors and health-promoting compounds. The analysis shows that while ASF generally exhibit higher baseline bioavailability of several essential micronutrients and protein (measured by PDCAAS and DIAAS) due to the absence of phytates and oxalates, plant-based matrices offer distinct physiological benefits, including dietary fiber and phytonutrients. Moreover, the lower bioavailability in plant sources can be significantly improved through food processing techniques (e.g., fermentation, germination, thermal treatment) and strategic dietary combinations. Therefore, adequate nutrient intake depends not only on the food\u2019s origin but also on its preparation methods and the overall dietary pattern. It is also important that the best diet is both nutritionally adequate and sustainable for the individual and the environment.<\/jats:p>","DOI":"10.3390\/nu18172882","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T09:20:43Z","timestamp":1788427243000},"page":"2882","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bioavailability of Nutrients from Animal-Derived Foods Versus Other Sources of Foods: A Comprehensive Literature Review"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9018-4525","authenticated-orcid":false,"given":"Mariusz","family":"Rudy","sequence":"first","affiliation":[{"name":"Department of Agricultural Processing and Commodity Science, Institute of Food Technology and Nutrition, Faculty of Technology and Life Sciences, University of Rzesz\u00f3w, Zelwerowicza 4, 35-601 Rzeszow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"633S","DOI":"10.1093\/ajcn\/78.3.633S","article-title":"Bioavailability of Iron, Zinc, and Other Trace Minerals from Vegetarian Diets23","volume":"78","author":"Hunt","year":"2003","journal-title":"Am.
