WIC subsidies can be used for milk, cheese, and all kind of vitamin-fortified processed grain gunk, as well as baby foods, formula, and so on. None of this stuff (except single-ingredient baby foods) is any “healthier” than steak and crab legs: it’s just cheaper.
If you give people money or the equivalent, you simply can’t control what they do with it.
