I think it's bad for the whole family to eat box lunch, because the box lunch you bought outside is first of all plastic products, which is bad for your health. The second kind is the food you buy outside. In order to taste good, they will add some additives and delicious spices in it, which is not good for the liver. Therefore, if the whole family eats box lunch, it must be broken for a long time. It's best to cook some food at home, which is clean and hygienic and good for your health.
