Total fat (Panel a), protein (Panel b), total carbohydrates (Panel c) in modeled and observed diets, overall and by age group. Error bars are 95% confidence intervals. Model 1 is substitution of all solid snack foods with the composite tree nut and Model 2 is substitution of all solid foods except for whole fruit, non-starchy vegetables and foods where more than 50% of the total grain comes from whole grains. P-value of difference comparing each model to observed value is indicated by asterisk (***p < 0.001; **0.001 < p-value < 0.01; *0.05 < p < 0.01). Hypothesis testing comparing Model 1 to Model 2 was not conducted. A reference line is provided which corresponds to the Daily Value, commonly used on food labels. The Daily Value may not apply to children less than 4y and for pregnant or lactating women
