I kind of mentioned that vicious cycle before,

我稍微提一提先前的那个恶性循环
is that when you take out the unhealthy a la carte,

就是当你逐个去掉非健康食品
and put in things like baked chips, or low fat frozen yogurt,

并加入如烘焙薯片或低脂酸奶之类的东西
and your a la carte sales do go down,

你的食品销量就会降低
so definitely children are less likely

因为比起普通薯片
to buy the baked potato chips than the regular potato chips.

孩子们明显不太喜欢买烘焙薯片
However, they're still hungry, they have to eat something.

但他们仍然会饿需要吃点什么
What happens is most times,

大部分情况下
it's as though the kids say of fine I'll just buy the school lunch

似乎一旦学校不再卖零食了之后
since there's nothing good over here with these snacks,

孩子们光靠吃顿午饭就能饱一天了
and so your lunch sales go up.

所以午餐的销量上去了
What we know from the previous research
