Each model is controlled for age, sex, ethnicity, education and poverty/income ratio.

The value of the R²shows the proportion of the variance in total energy intake that could be explained by all the variables included in the model.

The value of the partial R²shows the proportion of the variance in total energy intake that could be explained by the meat and/or vegetables and fruits or grain variables included in the model.
