JFC obviously you need more than rice, beans, and ground beef. But things like this make up the bulk of your calories. Not all, the bulk.
Frozen vegetables are fine, in fact they study it and it's even better nutritionally because the vitamins are frozen and don't start to break down. Canned vegetables are probably fine too, not sure if they add sugar or salt.
This is the problem, people think you need fresh everything everyday and that broccoli needs to bulk of your calories or something like that, and you don't. The bulk (not all, the bulk) of your calories can come from very basic foods. You can eat healthy if you know some basic cooking.
You keep discounting things like rice, beans, all the meats I listed, and now you discount frozen vegetables, canned vegetables. You discount all the stuff that is cheap and healthy. These are the basic foods that you need to learn how to cook. This is the problem, you think everything needs to be fresh everyday and you can't get the bulk (not all, the bulk) from basic foods.
Ok taxes, I doubt tax increases will ever go to the poor. Nor do I think this would be that expensive to teach cooking. When you look at how much we spend on schools and teachers, adding some hot plates and ovens is minuscule. You replace hours in one class with another, no change in teachers.
On to how this will save money, do you know how many problems come from obesity? And diabetes? How many other issues? Look at the health care costs, it's outrageous. Some basic cooking skills will go a long way to prevent a lot of this, saving money for both people and government. Just need a tiny little bit at the start and it'll save money for everyone.
