Impact of different protein sources on acute muscle protein synthesis following resistance training: a systematic review with standard and dose-response network meta-analyses.

Researchers compared acute muscle protein synthesis after resistance exercise and single doses of different proteins, which matters when selecting post-training nutrition. A systematic review covered 51 trials in healthy adults using muscle biopsies and tracer methods, followed by standard and dose-response network meta-analyses. Native whey, pea, whole egg, mycoprotein and whey ranked highest, with some sources showing predicted peak responses at 18-25 g. Only whey had a statistically significant effect, leaving comparisons involving sparsely studied proteins uncertain.

Upcycling Vegetable Waste Into Functional Food Ingredients via Synergistic Microbial Engineering and Artificial Intelligence.

Vegetable waste conversion could become more consistent when engineered food-grade microbes are paired with AI, which matters because variable feedstocks, resistant plant structures and fermentation toxins hinder industrial use. The review examines modified Saccharomyces cerevisiae and Escherichia coli, AI-guided enzyme design, metabolic models, process control and digital twins. It reports better conversion, toxin tolerance and batch consistency, with outputs including single-cell protein, flavour additives and packaging materials. The approach has merit, but the abstract provides no quantitative evidence of industrial performance.

Enzyme kinetics and engineering strategies for sustainable alternative protein production: From plant and microbial systems to cultivated meat.

The chapter examines how enzyme kinetics and engineering could improve proteins made from plants, microbes, algae, precision fermentation and animal cell culture, a key issue for product quality and scale-up. It reviews inhibition, catalysis and models for mixed protein substrates, alongside uses of transglutaminases, carbohydrases and lipases. It also assesses rational design, immobilisation, directed evolution, computational methods and links between kinetic models and bioreactors. The authors conclude that combining these tools can improve food properties and production efficiency, though the abstract reports no new experimental evidence.

Cultivated meat at industrial scale: Hygiene, externalized burdens, and the social conditions of meat wholesomeness.

Industrial-scale cultivated meat is assessed as a more controlled alternative to intensive livestock, with consequences for food safety, ethics and fairness. The commentary compares livestock’s environmental footprint, animal harm, microbial hazards, dangerous work and uneven community exposure with cell culture using enclosed systems and batch tracking. It identifies possible gains in hygiene, lower reliance on slaughter and inclusion of people who reject conventional meat. Yet energy use, growth media, scaling, concentrated ownership, cost and public confidence remain unresolved, so tighter control alone cannot ensure wholesome or just meat.
