New research found that replacing traditional proteins with mealworms in high-fat diets for mice could offer numerous health benefits including reduced weight gain and improved cholesterol. While there’s hesitation in Western societies about insect consumption, it’s an environmentally sustainable protein source.
With the world’s population on the rise and climate change intensifying, there’s an increasing need for sustainable protein alternatives. While plant-based “meat” and “dairy” have gained popularity, they’re not the sole green alternatives to traditional meat.
Research from the University of Illinois Urbana-Champaign, conducted on mice, indicates that substituting conventional protein sources with mealworms in high-fat diets could slow weight gain, improve immune response, reduce inflammation, enhance energy metabolism, and beneficially alter the ratio of good to bad cholesterol.
“In addition to more dietary fiber, nutritionists also recommend eating more high-quality proteins as part of a weight management plan. We knew from an earlier study in roosters that mealworms are a high quality, highly digestible protein source that’s also environmentally sustainable,” said lead study author Kelly Swanson, professor in the Department of Animal Sciences and interim director of the Division of Nutritional Sciences, both in the College of Agricultural, Consumer and Environmental Sciences (ACES) at U. of I.
Swanson’s team fed mice a high-fat diet (46% calories from fat) with casein, a protein from dairy, for 12 weeks before switching to the alternative proteins. Another group, the control, consumed a lean diet with casein throughout the experiment. By the time mealworms were introduced, the high-fat diet group was obese and experiencing metabolic syndrome, a cluster of conditions increasing the risk of heart attack, stroke, diabetes, and other health problems.

The mice then started eating two types of mealworms in a dried, powdered form similar to flour, substituting either 50% or 100% of the casein in the diet. During and after 8 weeks on the experimental diets, the research team measured body weight, body composition, blood metabolites, and gene expression of the liver and adipose (fat) tissue.
Mealworm protein didn’t cause obese mice to lose weight, but their rate of weight gain slowed relative to mice consuming high-fat diets with casein. And the benefits went further than that.
“It’s not a weight loss situation; they just slowed their gain with the mealworms,” Swanson said. “The more significant impact was the improvement in their blood lipid profiles. Their LDL, so-called ‘bad cholesterol,’ went down and the HDL, ‘good cholesterol,’ went up. And from a gene expression perspective, inflammation went down and some of the lipid and glucose metabolism genes were altered. Not everything was positive, but metabolically, they were in a better place.”
Some of the benefits might have been associated with chitin, a fibrous material that makes up the exoskeleton of insects. Swanson said although the role of chitin hasn’t been well studied, it seems to act like a fiber, stimulating beneficial microbial activity in the gut. He has another paper in the works to characterize the effects of mealworms on the mouse microbiome. Other studies have evaluated alternative proteins for obesity weight management in mice, but most have used genetically altered mice designed to stay obese no matter what. Swanson’s team intentionally used “wild type” mice so they would gain weight the same way many humans do: through diet.
But are humans ready for mealworm protein?
“There’s a ‘yuck factor’ for many in Western societies, where eating insects is not quite normal, but some populations have relied on insect proteins for millennia,” Swanson said. “With protein shortages becoming a reality, there may be a place for insect meals.”
For now, though, mealworm protein hasn’t yet been approved by the Food and Drug Administration. Insect-curious folks can try cricket flour, which can be used in foods according to the Food, Drug, and Cosmetic Act.
“You’re not seeing legs or anything like that,” Swanson said. “It’s just a flour that shouldn’t negatively impact the taste or other properties of foods.”

Then you eat it.
More and more articles about insects as a food product and the wonderful benefits. Priming the pump.
Wonderful. Now they will be making meal worm flour for everything.
But not for me.
Basically the same as every other bug-eating article that has ever been published. Bugs are good for you. Meat is bad for you and the planet. You have to get over your distaste for eating bugs cuz we’re gonna force you to eat the anyway.
(Meanwhile, the ruling elite will eat fillet mignon, caviar and crepes suzettes.)
Keep in mind, the ultimate goal is to eliminate 80% of the world’s population.
“...nutritionists also recommend eating more high-quality proteins as part of a weight management plan.”
~~~
Yes, it’s called keto, or atkins, or like many others, and the they poo-poo’d it when it was called those things, but now that you can politically frame it as being from insects, suddenly it’s good. But I saw nothing in the article that defined the amino acid profile of insect sources specifically. So this is just politics.
Cow meat bad. Cockroach meat good. /npc
Ya...right.
TAPEWORMS?
“ With the world’s population on the rise and climate change intensifying, there’s an increasing need for sustainable protein alternatives”
So much wrong here.
Premise is not true and if it were there’s no “need” for protein alternatives.
Also, these people always have a totalitarian mindset. Nothing is stopping them from developing and selling it as food for humans.
But they want to force people to eat it by fiat.
Well, yeah.
When somebody tells you you’re eating worms you lose your appetite. Ergo, you lose weight!..............
Nope. Unhhh Unhhhh
If insects are so great why haven’t humans been gobbling them up from day one ?
I’m telling the jerks behind this push to eat insects right now: You make me eat a bug, by force or by deception I will end you. There is a line and that’s it.
Knock this crap off, humans should not and do not need to eat insects.
Good. Feed the mealworms to chickens, then harvest the eggs (VERY high-quality protein), and when the hen stops laying, slaughter the flock, dress them out, and make chicken soup, also a relatively high-quality source of protein.
Chickens exist to convert insect protein to quality protein for human consumption. Chickens are - useful.
Or a nice fat trout, fresh out of the stream.
And it is Safe and Effective, too!
