Abstract on plant-predominant diets and protein intake across life stages
This abstract describes a whole-food, plant-predominant diet as linked in mechanistic and clinical studies to lower risk of several chronic diseases, and notes that some adults may benefit from protein above the adult RDA of 0.8 g/kg/day. [1]

Plant-predominant diet claims in the abstract
The abstract presents a whole-food, plant-predominant diet as part of lifestyle medicine, alongside physical activity, sleep, stress management, social connection and avoiding risky substances. It states that mechanistic and clinical studies link such diets to reduced risk of cardiovascular disease, diabetes, cancer and depression, through proposed pathways such as greater microbiome diversity, more short-chain fatty acid production, less oxidative stress and inflammation, and better insulin sensitivity. It also mentions psychological well-being via nutrient pathways affecting neurotransmitter synthesis and the gut-brain axis. These are described associations, not proof that the diet causes these outcomes.

Protein above the adult RDA for some patients
The abstract says some patients can benefit from protein intakes above the Recommended Daily Allowance of 0.8 g/kg/day for adults in a variety of settings. It adds that well-planned plant-based diets can reach significantly higher protein levels using legumes, soy, grains, nuts and seeds. It states that adequate, well-distributed protein supports fertility, fetal growth, lactation and preservation of lean mass through perimenopause and aging. No specific amounts above the RDA, patient groups or study designs are given in the abstract.

Health-span framing without reported study details
The abstract concludes that whole-food, plant-predominant diets with individualized protein guidance can extend health span, enhance functional independence and reduce medication dependence. It does not report sample sizes, follow-up periods, comparators or effect sizes, and it does not separate which findings come from mechanistic versus clinical work. Because only the abstract was available, the full text was not reviewed, and the described benefits should be read as the authors' summary rather than confirmed results.
