Great comments, we have elaborated more on income, lines 419-428, 503-506, 533-537 and 550-555. We have also included a detailed section about the significance of school lunches and education in Sweden across different SES groups lines 528-532. In Sweden the school lunch is of rather high diet quality, reaching many of the national dietary recommendations and is provided free of charge regardless of income or SES. However, it would be insightful to a complete a deeper analysis investigating the differences of school quality across differing socio-demographic areas. Nonetheless, the problem related to diet quality may lie in the food provided at home as financial constraints are most likely to be of more significance, lines 528-534.
The conclusion is sound given the findings but the lack of reference to income is an issue as educational status of parents is often a “de-facto” measure for income. It maybe, it is the cost of living associated with fresh fruit and vegetables that is the real issue. Given the findings the researchers could be arguing that a review may be needed with the Swedish school lunch program and increase the level of fruit and vegetables in the students' diet, particularly for students in lower SES locations. Schools may be making the lunches to a budget rather than to a healthy diet criteria which is more expensive. Different sub-populations even in the same school may need different mix of foods. A public education program could also be encouraged about health eating.
