Those are good points. I wasn’t suggesting only kale, but rather all vegetables, many of which have reasonably stable shelf lives, or could be minimally processed to become stable and more easily usable (powdered potatoes or boxed tomato puree come to mind). And if we are subsidizing them, then the price would be the same as 2000 calories of corn, or possibly less. If they were subsidized on a local level, rather than nationally, we could also stop trucking around all this food, and save oil and money too.
It’s such a waste when you think how much we convert oil into fertilizer into corn into sugar, and call it food.
When you factor in the rising and outrageous price of health care in the US, much of which is tied to diseases linked to diets high in sugar and carbohydrates, there would be a significant savings for taxpayers and better health for more Americans.
