Validating Healthy Eating Index, Glycemic Index, and Glycemic Load with Modern Diets for E-Health Era

Area of Science:

• Nutritional Science
• Computational Nutrition
• Personalized Medicine

Background:

• Understanding dietary predictors is crucial for personalized nutrition strategies.
• Modern diets vary significantly in their impact on health metrics.
• The e-health era demands data-driven approaches to dietary management.

Purpose of the Study:

• To identify predictors of healthy eating parameters like the Healthy Eating Index (HEI), Glycemic Index (GI), and Glycemic Load (GL).
• To analyze various modern diets for their influence on these parameters.
• To inform personalized nutrition strategies within the e-health framework.

Main Methods:

• Utilized Nutrition Data Systems for Research (NDSR) software for dietary analysis.
• Employed artificial intelligence and machine learning for predictive validation.
• Included HEI, caloric sources, and diet types as modifiable factors.

Main Results:

• Whole fruits, whole grains, and low empty calories predicted higher HEI.
• Carbohydrates were a common predictor for GI and GL.
• Mexican diets, total fruits, and carbohydrate intake influenced GI.
• A median of 33.95g carbohydrates per meal (3.59 meals/day) was predicted for GL < 20.
• Smoothies, convenient, and liquid diets required more carbohydrates and meals for acceptable GL.

Conclusions:

• Identified key dietary components and food types influencing HEI, GI, and GL.
• Quantified carbohydrate intake recommendations for managing GL.
• Findings support tailored dietary interventions for diverse populations in the precision e-health era.
