^*Significantly different based on non-overlapping 95% CIs

All ICCs are from mixed models adjusted for youth’s age, youth’s sex, youth’s Hispanic/Latino background, youth’s nativity, parent’s education, and household income as fixed effects and family as a random intercept

^†Includes fruit juice

^‡Includes all forms except juice

^§Includes any beans and peas not counted as total protein foods

^¶Includes all milk products (e.g., fluid milk, cheese) and fortified soy beverages

^#Beans and peas are included here when the total protein foods standard is otherwise not met

^**Includes seafood, nuts, seeds, and soy products (other than beverages), as well as beans and peas counted as total protein foods

^††Ratio of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA) to saturated fatty acids (SFA)

^‡‡Calories from solid fats, alcohol, and added sugars; threshold for counting alcohol is >28 grams/day
