Nutritional redundancy in the human diet and its application in phenotype association studies

X. Wang, Y. Hu, et al.

This groundbreaking research examines 'nutritional redundancy,' revealing how diverse individual diets can contribute to stable overall nutrient intake. By introducing a novel measure of nutritional redundancy and linking it to healthier outcomes, the authors illuminate a path toward better understanding healthy aging and disease risk. Conducted by Xu-Wen Wang, Yang Hu, and colleagues, this study is a must-listen for anyone interested in nutrition and health.

Abstract

This paper investigates the concept of 'nutritional redundancy' – the observation that while individual food intake varies greatly, the overall nutrient intake remains relatively stable. Analyzing five cohorts with diverse dietary data, the authors demonstrate this stability and attribute it to the nested structure of the food-nutrient network. A new measure of nutritional redundancy (NR) is introduced, showing no strong correlation with existing healthy diet scores but comparable predictive power for healthy aging. Higher NR is associated with lower risks of cardiovascular disease and type 2 diabetes.
