Since nutrition standards were strengthened in 2010, eating at school provides many students with healthier food than is available cheaply elsewhere. Plus, reducing stigma increases the number of kids getting fed.
Did you read the article? What if most of what a kid is eating isn't what their parents are eating?
Since that time, there has been a substantial increase in schools participating in the Community Eligibility Provision, a federal policy that allows schools in high poverty areas to provide free breakfast and lunch to all attending students.
So these kids are eating two meals a day that aren't directly provided by their parent. Sounds like most of their meals aren't what their parents are eating.
Also, if they are in extreme hardship, they may not even get to eat dinner with their parents.
But your argument is that they are obese because they eat what their parents eat, right? So if 2/3rds of their meals aren’t from those unhealthy parents, wouldn’t the kids be healthier?
If kids are getting fed at school, that means the family can afford better stuff. Even if they keep buying garbage, the kids will be exposed to the idea of healthy eating.
