Replacing potatoes or rice with pulses can lower your blood glucose levels by more than 20 per cent, according to a first-ever University of Guelph study.
Prof. Alison Duncan, Department of Human Health and Nutritional Sciences, and Dan Ramdath of Agriculture and Agri-Food Canada, found that swapping out half of a portion of these starchy side dishes for lentils can significantly improve your body's response to the carbohydrates.
Replacing half a serving of rice with lentils caused blood glucose to drop by up to 20 per cent. Replacing potatoes with lentils led to a 35-per-cent drop.
"Pulses are extremely nutrient-dense food that have the potential to reduce chronic diseases associated with mismanaged glucose levels," said Duncan, who worked on the study with PhD student Dita Moravek and M.Sc. students Erica Rogers, Sarah Turkstra and Jessica Wilson.

There is a reason lentils stewed/curried lentils over rice are such a popular dish. They're cheap, easy, delicious, healthy, and even give you a complete protein. I noticed way back in high school that all successful cultures have figured out that pulse + whole grain = complete protein. It was lentils and wheat in the ancient Near East, corn and common beans in Mesoamerica, soybeans and rice in south China, etc etc.
If the US ag sector is smart, especially as drought conditions worsen, we'll see a shift to grain-and-pulse pairing in farming. I'd suggest three areas of concentration: tepary beans, teff, and sorghum.

Yeah, and its also a cheap food. Here in Oz its about $5 per kg for dried lentils. Once cooked a kg becomes more lime 2-3 kg. Compare that to beef at over $18 per kg or chicken at $12 per kg.
If I was struggling to pay the bills, I'd be switching most of my meat to lentils.

That's reasonable (3.72 USD, ~1.69 USD/lb), but I try to get it (or any kind of dried legumes) at 1 USD / lb or less.
Red lentils also cook incredibly quick. Slap some tomato sauce and spices in there, put it on rice.

Grain and pulse pairing?
You mean, like, say, maize/corn and soy?
Like most of the midwest?
What sort of shift do you mean?

A shift to one that's more drought-tolerant. Look up the conditions teff and tepary beans grow in, and compare to corn and soybeans.

Ain't that simple.
For starters, not all of the midwest is expected to get less water under best simulations of expected climate change.
Changing practices mean less water used, and less water lost.
The soils aren't the same, and in areas that have been doing the stripmine-and-replace-with-petrochemicals style of monocrop farming, you won't get a lot of return without more of the same - and you won't win any prizes for figuring out that water isn't really the limiting factor on productivity there.
I mean, sure, you could do it. You could also go bust doing it.
Agronomy is hard.

Oh, definitely. One of the things I was studying in college was soil remediation (of course, we all know how *that* went...). I'm not sure it's even possible to restore natural soils to the region in any time frame at all, let alone in a way that doesn't mean we all starve. We can't exactly fallow the entire Midwest with clover for half a decade, even *if* the soil hadn't been more or less strip-mined, as you put it.

They also work surprisingly well in vegetarian burritos, and they play very nice with guacamole and other Mexicanny things.

Caucasians have ANE and Caucasus Mountains origins. That far north, people have adapted to dairying and fishing, though agriculture of course is still a going concern. As far as I know, their cereal crops are wheat and rye with some oats? Will admit I don't know too much about the Nordic ag sector...
