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.”

These misanthropic people are hilarious.

Finally found it. Not an easy sell to the public with Cockroach fritters or Maggot Chop Suey but throw in a possible weight loss and the product will fly off the shelves.
So are pigs. Go to any poor country and you'll see plenty of both. Chicken wings wrapped in bacon is my choice but if these idiots want to eat cockroaches wrapped in night crawlers I'm not going to stop them.
Progressives' could actually do something productive for a change and help reduce the roach population but they will likely declare them an off limits endangered species or worship them as their new god.
OMG. How pathetic are they, trying to gaslight us into eating zee bugs.
Slows weight gain….
Because it makes you sick!!
Propaganda. Eat your insects, proles, they’re good for you.
They missed the marketing that might actually work. No one cares about ‘slows weight gain.’ But if it actually caused WEIGHT LOSS, well, that’s another matter! ;-)
They’ve been getting ideas from Snowpiercer.
No sale.
I just finished a T-bone steak for dinner. They were on sale this week.
Eat bugs? BARF
Our locally owned grocery store (10 miles) still has a great meat market. They cut and package it in house. You simply cannot beat them at this.
We also have a meat processing building at the farm. Never for commercial use, but we know how to use it. Make some good beef sausage. Have the best recipe in the state.
When you look at how many people are planning this behind the curtain, they are vastly outnumbered.
They think they are God. God knows they are not.
They can take their nonsense and put it where the sun don’t shine.
Tomah.
“Knock this crap off, humans should not and do not need to eat insects.”
Bump!
I don’t care, I won’t eat bugs.
I will eat human meat before I eat bugs. Ideally, human meat from one of the little hitlers pushing insect protein.
Slooooooly they lead you to accept anything.
Next, they’ll tell us insect protein increases penis size by 80%
You'll also see a lot of goats.
Their meat and milk isn't as popular in America as is beef, pork, and chicken, but it's quite good.
That is also the Old Testament. I agree bugs can be eaten in emergency or real survival situations but I don’t believe that humans were meant to get their protein from bugs and bugs only.
Who knew mice needed a better diet to keep their weight and cholesterol under control?
