This article examines the association between dietary protein diversity and frailty risk in older Chinese adults. The key findings are: 1. Higher protein diversity was linked to lower frailty risk, with each 1-unit PDS increase reducing risk by 10%. 2. Consistently maintaining a high PDS over 4 years was associated with the lowest frailty odds.
The global food system faces mounting pressures from climate change, resource competition, conflict, and markets, with the harshest impacts falling on nutritionally vulnerable populations. Meeting this challenge demands a paradigm shift in how food is grown and distributed, supported by new science, policy reforms, and broad transformations from farm to fork.
A high plant-based diet index was associated with a lower risk of frailty in older Chinese adults, especially in men and those with healthy lifestyles. Consistently maintaining a high plant-based diet over time significantly reduced the risk of frailty. The protective effects of a plant-based diet against frailty were not observed in women and those unhealthy lifestyles, suggesting gender and lifestyle-specific differences.
This review highlights how essential oils can be effectively used as natural food preservatives through advanced delivery and packaging techniques, supporting the shift toward environmentally friendly alternatives to synthetic chemicals in global food systems while addressing sensory and regulatory challenges.
