Corn Shouldn't Be Food, But It Is

[@laurenthomas7074]

I absolutely love talking about how AMAZING the Indigenous New World peoples were at domesticating crazy and seemingly terrible plants - they turned a poisonous tiny root into basically the king if all single foods - the potato! Their ingenuity was incredible, while the mesoamericans made corn (and more I'm sure!) the Andes were full of incredible potatoes and other plants on terraces - multigenerational projects designed to gradually adapt crops to different altitudes. Then we have water and irrigation system of the Huari/Wari too!

[@bomafett]

And potatoes and tomatoes are both in the poisonous nightshade family.

[@genio2509]

Also I believe pumpkins too (my theory) where I live here on Yucatan, at the southeast of Mexico, there are some small green pumpkins, while on the US and Canada there are the classic big orange pumpkins, it looks to me like selective breeding, but I have no real info. If someone knows I'd love to hear.

One note that usually gets missed and is an important note: What most people think of with corn (soft sweet kernels) is actually a fairly recent thing, and is only a small fraction of corn grown and used. Called "sweetcorn" The vast majority of corn grown is hard and starchy. And is harvested well after the crop has died and let dry out in the field. "Field corn" or "yellow #2 corn/maize" is what is overwhelming grown and used in everything from cereal to animal feed. And popcorn is a seperate small fraction of corn in its own group.

[@iafarmlife3766]

Yellow corn is actually Dent Corn. It was developed in the late 1800s. When it's called yellow #2 it's more of a grade than a name. Yellow #1 is the same thing just higher quality. Most Dent corn is sold as Yellow #2 as that is the largest market. Before Reid, the breeder of Dent Corn, developed the first Dent corn most corn grown was red. Reid bred a red variety with various Flint and Flour varieties to produce Dent corn. It just happened to be yellow. Soon after hybridization was developed and Dent Corn proved to work the best in this system. So today nearly all corn grown is related to what James L. Reid developed.

[@iowafarmboy]

yes! I remember until the 2010s in India, they had a different type of corn than I was used to in the United States. Then all of a sudden, every vendor replaced that corn with sweetcorn. Also, big on the animal feed bit. It takes a lot of water to create the field corn, and that corn is also used for ethanol creation

Another important factor was likely the co-domestication of beans. Growing the two plants together may be another reason for selecting teosinte/corn with larger stalks - the corn stalks may have initially been used as scaffolding for the bean vines to grow on. Growing corn and beans together also keeps the soil healthier, as the bacteria in the root nodules of the legumes perform nitrogen fixation. And the combination of corn and beans also provides all of the amino acids necessary for a healthy diet.

Back in my botany classes in college, I made the joke "there is nothing we can do to corn that corn wouldn't do to itself given the opportunity."

And on top of that, corn belongs to a evolutionary lineage of plants that opted for a more rare but efficient photosynthetic process that will make them outlast other plants in less friendly environments in both temperature and sunlight. And people are genetically experimenting rice to adopt that kind of photosynthesis to greatly reduce water and soil needs, which is something that can't be done through cross-breeding, the OG genetic engineering method of antiquity.

The invention of Nixtamalization is also easy to guess: You want corn soup, but your pot is made of wood and you don't want to make a new pot every time after cooking. So instead of putting the wooden pot over the fire you put stones in the fire to heat them. Then you take the hot (and usually ashy) stones and throw them in the pot to heat the soup.

I grow Hopi Blue Corn near its ancestral homeland in Northern Arizona. This variety is said to be over 1200 years old, and is much more like modern sweet corn (dent corn) than many of the flour corn varieties grown in the Eastern US. The Hopi people do not claim to have domesticated this corn, but that it was brought to them by other worldly beings. It has a profoundly deep root system (upwards of 5 feet deep) and was grown on the arid mesas of the southwest entirely grown by rain. It was typically grown alongside squash and beans in a practice known as "The Three Sisters". The squash, with their broad leaves and long vines, would shade the ground from the intense heat, slowing water evaporation, and the legumes (beans) were used to fix atmospheric nitrogen into the soil, thus making a sustainable agricultural model for arid farming practices. The drought tolerance of Hopi Blue Corn is incomparable to modern corn, and is ultra rich is B vitamins and 40% higher in protein. This is, of course, to no avail without nixtamalization, which can be done with either potassium hydroxide (wood ash/lye), or calcium hydroxide (quicklime/pickling lime). To nixtamalize, simmer the corn kernels in the alkali solution for around 30 minutes, remove from heat, let sit for around 24 hours. Strain (careful, lye is caustic), and rinse thoroughly to remove the alkali. You then need to remove the germ (outer shell of the kernel) by crushing the kernels in your hands in a bowl of clean water. If the nixtamalization was done properly, the germ should easily seperate and float to the top of the water which can then be strained or poured off. A little bit of germ leftover is OK. You can use the fresh nixtamale (wet) as hominy, or can easily grind it into a dough for tortillas. This is how you make authentic tortillas: there is no other way around it. You can also dry the ground nixtamale and further reduce it to a dry flour for long term storage.

Maize is the actual specific name for the corn native to the Americas that this video talks about. The word "corn" is a generic English (ie. British Isles English) term for almost any form of grain. Wheat, barley, oats, etc can all considered corn according to the original word's meaning.

Second Prehistoric Mesoamerican: 'No problem, I will just invent an alkaline chemical process called nixtamalization and start an oral tradition that will extend thousands of years in the future to pass along instructions of how to make the then genetically modified plant species edible.'

When I went to Péru a few years ago, I visited a salt mine (a video in itself right there!) but one of the things we "just walked past" was a display of many varieties of maize, of varying sizes and colours. We got told about the cultivation, and the way that they had basically a research facility built into a natural basin where they used coils from many regions of the country, at different depths into the basin (to get different temperatures), then grew different varieties of maize, to work out which one would grow best in each geographical region. They did the same with potatoes. So there's a total of three video ideas for you!

There was something similar in Cali I think.

[@michaeldougherty6036]

Between rice, wheat and corn, most of modern human's diets consist of heavily mutated grasses. Then realize that most of what we consider our leafy greens are actually the same plant selectively mutated into different versions to favor different parts. We've also cross-bred most natural fruit to get fruit more appealing to us. Same thing with roots and tubers. All before the panic over GMO's ever caught hold.

Bloomers of war spread quickly -under mushed voices at first- but it soon sprouted into full-grown cropaganda. The campaigns were effective enough at compelling me to join the farmy. Heh... I was so green, naively thinking I was going to grow forever. My Cob, was I wrong... Nothing quite prepares you for it until you cereal combat with your own eyes. The total cornage that first day left me shucked and amaized. My whole plantoon was nearly creamed amid all the shelling! Our kernel lost an ear. My close spuddy lost an eye... By some miracle gro, while garden' the perimeter, I spotted a clear root to victory. With grits and determination, we grained the high ground needed to control the field.

I do wonder why the ingredients of a jar of Jiff PB., (it's first industrial maker), lists veggie oil. Are they taking the peanut oil and selling it to fast food fryers?

In a galaxy far, far away, there was a battle unlike any other. It was not fought with blasters or lightsabers, but with ears of corn. This was the Corn Wars. The conflict began when the planet of Naboo discovered a new type of genetically modified corn that could grow faster and yield more kernels than any other crop in the galaxy. They shared their technology with the rest of the galaxy, but not everyone was happy about it. The planet of Dantooine, which was known for its traditional methods of corn farming, saw the new genetically modified corn as a threat to their way of life. They began to produce propaganda against the "unnatural" corn and urged other planets to boycott it. The Jedi Council tried to negotiate a peace treaty, but tensions continued to rise. Soon, there were battles breaking out across the galaxy as supporters of the new corn and traditionalists clashed. Corn fields were burned, husks were strewn across battlefields, and the sound of popping kernels echoed through space. The galaxy was in turmoil. The Jedi, led by the wise Master Yoda, tried to maintain peace and find a solution that would satisfy both sides. But as the war dragged on, it became clear that there could be no winners in the Corn Wars, only losers. In the end, a compromise was reached. The new corn would be allowed to grow, but traditional methods of farming would also be preserved. And so, the Corn Wars came to an end, with the galaxy finally at peace. But every year, on the anniversary of the start of the war, the citizens of the galaxy gather to celebrate with a corn festival, where they feast on corn in all its many forms and remember the lessons learned from the Corn Wars.
