Abstract

Dietary proteins derived from animal sources, although containing well‐balanced profiles of essential amino acids, have considerable environmental and adverse health effects associated with the intake of some animal protein‐based products. Consuming foods based on animal proteins carries a higher risk of developing non‐communicable diseases such as cancer, heart disease, non‐alcoholic fatty liver disease (NAFLD), and inflammatory bowel disease (IBD). Moreover, dietary protein consumption is increasing due to population growth, posing a supply challenge. There is, therefore, growing interest in discovering novel alternative protein sources. In this context, microalgae have been recognized as strategic crops that can provide a sustainable source of protein. Compared to conventional high‐protein crops, using microalgal biomass for protein production presents several advantages in food and feed in terms of productivity, sustainability, and nutritional value. Moreover, microalgae positively impact the environment by not exploiting land or causing water pollution. Many studies have revealed the potential of microalgae as an alternative protein source with the added value of positive effects on human health due to their anti‐inflammatory, antioxidant, and anti‐cancer properties. The main emphasis of this review is on the potential health‐promoting applications of microalgae‐based proteins, peptides, and bioactive substances for IBD and NAFLD.

  • Peptides from Limnospira platensis suppress inflammatory marker expression in endothelial cells, promoting a healthier vascular environment.

    “Notably, peptides from Limnospira platensis have been shown to suppress inflammatory marker expression in endothelial cells, promoting a healthier vascular environment [72].”

    From Navigating the potential of algal peptides: health effects, market applications, and scientific challenges (2026) · cites this paper as [72]

    In “Microalga-Based Proteins and Peptides” (page unavailable), the review reports that peptides from Spirulina maxima suppressed cytokine generation by endothelial cells. It discusses peptides from Spirulina platensis separately, but does not attribute this endothelial-cell effect to them. The claimed vascular benefit is an inference rather than a reported outcome.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
