Abstract
Purpose of Review
In accordance with US dietary guidance, incorporating variety into the diet can align with energy balance, though greater food variety in some categories may make energy balance more challenging. Thus, experimental and epidemiologic evidence is summarized on the relationship between food variety, food and energy intake, and energy balance.
Recent Findings
Lab-based, experimental research consistently demonstrates that greater variety within foods or sensory characteristics of food increases food and energy intake within an eating occasion. Epidemiologic evidence is less consistent, potentially driven by differing methodologies, particularly in defining and measuring food variety. Moreover, the effect of variety on energy balance appears to be moderated by food energy density.
Summary
Integrating insights from experimental and epidemiologic research are essential for strengthening food variety guidance including developing evidence-based definitions of food variety, understanding moderators of the relationship, and developing practical guidance interpretable to consumers.

This is the first study to examine the influence of within-meal variety (served and consumed) on energy intake in a free-living setting. Results from this study suggest that the presence of food variety within a meal can enhance energy intake, providing support for the hypothesis that humans habituate to sensory input (even visually), and that this can influence food intake. This study also provides additional support that food type/energy density moderates the influence of variety on energy intake, with greater vegetable variety leading to reductions in energy intake within a meal.
