Thank you, we agree that income as well as education plays a role in healthy food choices. However, the results in the article we are referring to looked at parental education, not income. As we did not have access to data in parental income, we were not able to include that variable in our paper
It is more that education it is also income re line 106-107 “It is proposed that parents with more educational experience are more likely to make healthier food choices for their family” . Miss the point It also assumes that parents with more educational experience are more likely to have higher incomes and so are more likely to make and avoid healthier food choices for their family
