Dear Colleagues

The global population's growth presents a challenge to traditional protein sources, leading to the urgency to explore alternative and more sustainable options. Alternative proteins, such as insects, algae, fungi, and fermented products, offer a promising avenue as they require fewer resources, produce fewer emissions, and can be cultivated in diverse environments, presenting a more sustainable and resilient solution to the protein demands of our expanding global community. Moreover, emerging research suggests that these unconventional protein sources offer not only environmental sustainability but also unique health benefits, including rich essential nutrients and bioactive compounds with antioxidant, anti-inflammatory, and prebiotic properties, positively influencing gut health and immune function. Therefore, the goal of this Special Issue is to provide a platform for all researchers to better understand the intricate connections between alternative proteins and human health, providing a comprehensive understanding of the potential physiological benefits and implications for diverse populations. By exploring these unconventional sources, we aspire to pave the way for a healthier and more sustainable future for global nutrition.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.
