Draft Conclusion Statement

The draft conclusion statements listed below describe the state of the science related to the specific question examined. Draft conclusions are not considered final until they have been deliberated with and decided upon by the full Committee and published in the Committee’s final advisory report. Individual conclusion statements should not be interpreted as dietary guidance or the Committee’s overarching advice to the Departments. 

Dietary Patterns: Children

Insufficient evidence is available to determine the relationship between dietary patterns consumed by children or adolescents and risk of type 2 diabetes. Grade: Grade Not Assignable

Dietary Patterns: Adults 

The 2020 Dietary Guidelines Advisory Committee conducted a systematic evidence scan and determined that the conclusion drawn by the 2015 Dietary Guidelines Advisory Committee generally* reflects the current state of science: Moderate evidence indicates that healthy dietary patterns higher in vegetables, fruits, and whole grains and lower in red and processed meats, high-fat dairy products, refined grains, and sweets/sugar-sweetened beverages reduce the risk of developing type 2 diabetes. 2015 DGAC Grade: Moderate

Diets Based on Macronutrient Distribution: Children

No evidence is available to determine a relationship between diets based on macronutrient distribution consumed during childhood and risk of type 2 diabetes. Grade: Grade Not Assignable

Diets Based on Macronutrient Distribution: Adults

Insufficient evidence is available to determine the relationship between macronutrient distributions with proportions of energy falling outside of the acceptable macronutrient distribution range for at least one macronutrient due to methodological limitations and inconsistent results. Grade: Grade Not Assignable
