似乎你在瞎扯，下面是网上找到的USDA的定义，并没有说什么营养均衡，就是没有足够的食物
The USDA defines food insecurity as a lack of consistent access to enough food for every person in a household to live an active, healthy life. This can be a temporary situation for a family or can last a long time.

看报告的Note 2对于food insecure的定义，受访者q需要在6个问题里至少两个回答“是”才会被算作Food insecure。评论里一直纠结的“吃的不均衡”（balanced meal）只是其中一个选项，只勾这条会被算作“marginal food security”。
