There has been a rash of articles lately that are encouraging bug eating. They claim that bugs are nutritious and will help save the planet. Here's one from CNN:

https://www.cnn.com/2019/10/25/heal..._source=twCNN&utm_term=link&utm_medium=socialOn a morning in the not-too-distant future, you might toast bread made with cricket flour, drink a protein smoothie made from locust powder, and eat scrambled eggs (made extra-creamy with the fat from mopane caterpillars) with a side of mealworm bacon.
That meal will give you four times the iron, more than three times the protein and more key vitamins and minerals than the bread, smoothie, eggs and bacon you eat today -- all while saving the planet.
No way you'll eat bugs, you say?
Well, sorry to break this to you, but if you eat chocolate, pizza and spaghetti, you are already eating insects -- and worse.
Bugs, rodent hair and poop: How much is legally allowed in the food you eat every day?
The US Food and Drug Administration allows 30 or more insect parts and some rodent hair in every bar of chocolate; nearly two maggots in a 16 ounce can of tomatoes or pizza sauce; and up to 450 insect parts and nine rodent hairs in every 16 ounce box of spaghetti.
There's just no way to get rid of all the creatures that might hitch a ride along the food processing chain, so the FDA has to allow what they call "food defects," which you eat without knowing. They are in many of our foods -- even peanut butter and jelly.
So why not eat bugs on purpose and simultaneously fight climate change?
Bugs are really good for you
Your friends and neighbors are already munching on insects. According to a report by Global Market Insights, the US edible insect market topped $55 million in 2017 and is expected to grow to nearly $80 million by 2024.
Europe's on track to do the same, while Asia Pacific nations are expected to eat $270 million worth of insects by the quarter of the century.
A growing demand for high quality protein, along with a movement toward sustainability and against processed foods, are a few of the reasons behind the growing popularity.
Here's another explanation: Bugs are very good for you.
Many countries and traditions have known this for decades, even centuries. According to a 2013 report by the United Nations Food and Agriculture Organization (FAO), at least 2 billion people worldwide eat bugs every day.
Worms served like French fries
"I've eaten bugs in many countries: termites, scorpions, beetle larvae, grasshoppers, silkworms. All very common," said entomologist Jeff Tomberlin, who directs the forensic and investigative sciences program at Texas A&M University.
"I had beetle larva that was incorporated into a quiche. I've had bamboo worms that were fried like French fries," he said. "I've had termites that were smoked and served as an appetizer, just like peanuts.
"As for the taste, it's sort of a nutty popcorn flavor," Tomberlin said. "The buttery flavor would be the fat of the insect and the nuttiness would be the chitin, or the exoskeleton."
The most commonly eaten insect groups globally, according to the FAO, are ants; beetles; bees; caterpillars; cicadas; crickets; dragonflies; flies; grasshoppers; leaf bugs; locusts; scale insects; termites; and wasps.
But there's lots more to choose from. More than 2,100 edible insects have been recorded in the world, according to Wageningen University and Research in the Netherlands.
And many of those are packed with good-for-you vitamins, minerals, fat and protein. In fact, insects are often considered delicacies.
Queen termites, for example, are so nutritionally dense that they are fed to undernourished children in Uganda and Zambia.
Consider those mealworms you had instead of bacon at our imaginary breakfast. They have higher unsaturated omega-
3 levels than fish, as well as the same protein, vitamin and mineral content.
The cricket protein in the toast you hypothetically enjoyed is said to be a "complete protein" just like fish, meat, dairy and eggs. Complete proteins contain all nine essential amino acids needed to build and repair protein tissues in the body. We don't naturally make those essential amino acids, so we must get them through our diet.
In addition, each insect delivers an enormous punch of protein for its size.
Take the mopane caterpillar, one of the most highly prized and devoured insects in the world. One mopane worm, as they are called, provides between 48% to 61% of protein, and is a source of calcium, zinc and iron.

Then there's the fat content: 16% to 20% of the mopane worm is fat, of which 40% is essential fatty acids. The fat can add a creaminess to recipes (remember your future breakfast eggs?).
Bugs are good for the planet
And then there's the biggest selling point: Devouring bugs instead of methane-producing livestock is an easy, excellent way to deliver quality nutrition to the masses of humanity while helping the environment.

But it's not just protecting the ozone. Bugs don't use much water (there's a global water crisis). They can be grown on organic waste (poo-poo platter anyone?). And they can be grown vertically, in a small amount of space.
That last bit is huge: According to the FAO, over a fourth of the world's land is used for grazing livestock. Another third of the earth is dedicated to growing crops that will be eaten by livestock.
Just think of it: Bugs can be grown in small cages nested inside insect skyscrapers.
If that is huge, this next fact is gargantuan: Because they are cold-blooded and need less energy to stay warm, bugs need much less food than animals.
Crickets, for example, need 12 times less feed than cattle, four times less than sheep, and half the feed needed by pigs and broiler chickens to produce the same amount of protein, according to the FAO.
"If you look at the production of a pound of beef, you're looking at a conversion rate of about 20 to 1 -- 20 pounds of feed to produce one pound of meat," Tomberlin said. "If you look at insects, you're looking at about 2 to 1 ratio. So it's a much more effective conversion rate."
If that isn't enough, there's yet another plus: the fast life-cycle of insects.
This startup is saving crops by making 'super bees'
"While you may feed an animal for six weeks to ready it for market, during that same period you (could) have multiple generations of insects," Tomberlin said. "Add that to the fact that you can raise them in such little space, on so little feed, and you've got three ways in which insects are superior food products than livestock."
The 2019 population estimate from the United Nations says that our world will grow from 7.7 billion now to 9.7 billion in 2050.
Consider the devastating effects of climate change, overfishing, water shortages and a reduced productivity of crop-growing fields, and it's easy to see how insects will soon be the protein of the future.
Mopane worm hummus, anyone?
They are also trying to sell cockroach milk...
https://www.sciencealert.com/scientists-think-we-should-start-drinking-cockroach-milk-superfoodAn international team of scientists sequenced a protein crystal located in the midgut of cockroaches in 2016. The reason?
It's more than four times as nutritious as cow's milk and the researchers think it could be the key to feeding our growing population in the future.
Although most cockroaches don't actually produce milk, Diploptera punctate, which is the only known cockroach to give birth to live young, has been shown to pump out a type of 'milk' containing protein crystals to feed its babies.
The fact that an insect produces milk is pretty fascinating – but what fascinated researchers is the fact that a single one of these protein crystals contains more than three times the amount of energy found in an equivalent amount of buffalo milk (which is also higher in calories than regular cow's milk).
Clearly milking a cockroach isn't the most feasible option, so an international team of scientists headed by researchers from the Institute of Stem Cell Biology and Regenerative Medicine in India decided to sequence the genes responsible for producing the milk protein crystals to see if they could somehow replicate them in the lab.
"The crystals are like a complete food - they have proteins, fats and sugars. If you look into the protein sequences, they have all the essential amino acids," said Sanchari Banerjee, one of the team, in an interview with the Times of India back in 2016.
Not only is the milk a dense source of calories and nutrients, it's also time released.
As the protein in the milk is digested, the crystal releases more protein at an equivalent rate to continue the digestion.
"It's time-released food," said Subramanian Ramaswamy, who led the project.
"If you need food that is calorifically high, that is time released and food that is complete. This is it."
It's important to point out that this dense protein source is definitely never going to be for those trying to lose weight, and probably isn't even required for most western diets, where we are already eating too many calories per day.
But for those who struggle to get the amount of calories required per day, this could be a quick and easy way to get calories and nutrients.
"They're very stable. They can be a fantastic protein supplement," said Ramaswamy.
Now the researchers have the sequence, they are hoping to get yeast to produce the crystal in much larger quantities - making it slightly more efficient (and less gross) than extracting crystals from cockroach's guts.
Who needs kale and quinoa when you have cockroach milk supplements?
…Yeah, we aren't 100 percent convinced either. But if it helps alleviate the food shortages we'll have to deal with this generation, we'll take it.
