Insects Could Give Meaty Taste To Food and Help Environment, Scientists Say 211

Insects can be turned into meat-like flavors, helping provide a more environmentally friendly alternative to traditional meat options, scientists have discovered. From a report: Mealworms, the larval form of the yellow mealworm beetle, have been cooked with sugar by researchers who found that the result is a meat-like flavoring that could one day be used on convenience food as a source of protein. While mealworms have until now mostly been used as snacks for pets or as bait while fishing, they have potential as a food source for humans to help get the recognizable flavors of meat without the harmful impacts upon the climate, as well as direct air and water pollution, of raising beef, pork and other animal-based foods. "Insects are a nutritious and healthy food source with high amounts of fatty acids, vitamins, minerals, fiber and high-quality protein, which is like that of meat," says In Hee Cho, a researcher at Wonkwang University in South Korea who led the study.

"Many consumers seriously like and need animal protein in our diet. However, traditional livestock farming produces more greenhouse gas emissions than cars do. On the other hand, insect farming requires just a fraction of the land, water and feed in comparison to traditional livestock farming." Cho said that edible insects, such as mealworms and crickets, were "superfoods" that have long been enjoyed by communities in Asia, Africa and South America. However, people in Europe and North America are generally more squeamish about eating insects, despite recent forays by several restaurants and supermarkets into providing insect options for consumers.

      At least we know where the steak will come from...

    • I suspect most people would rather go vegetarian than start eating insects. Especially commercially produced insects in some weird nightmare farm factory. It seems so unnecessary. I'll eat tofu or whatever for some of my meals so I can still have steak and chicken once in a while. It's not so hard to adapt that I "need' to have cricket legs in my food.

        Wait 'til you try them, you'll be begging for more.

        "Tasty" doesn't even begin to describe them, and they always have that crunch that's so difficult to get just right in bacon.

          The desirable thing in the bacon is the flavor of the seared outside and the rendered fat... the crunch is just an indicator you got there. Insects lack all that goodness. It is all crunch and the bad kind that gets stuck between your teeth like someone ate a bunch of shrimp, meticulously squeezing all the meat out of the deep tail and you grab a handful of the discarded shells and eat them.

        Nope, they'll just have to find their cuts elsewhere because I and I think most people are not willing to give up beef. Especially with the ecological impact of growing those vegetables.

I do buy fresh chickens and rabbits from time to time (I hate plucking chickens compared to skinning rabbit). Heads and feet on my animals doesn't bother me. Funny thing is people often don't have a problem with catching and killing fish. They have heads and eyes on them too.

            I can't really get behind that. Pork chops can be tasty, in which case they've got bones and gristle through them making them a pain to eat or they can be as tasteless as chicken (center cut loin) and still have an annoying band around the edge. Rabbit is roughly on a level with chicken breast/center cut pork loin. Basically to get flavor out of those things you need to use a bunch of salt and the fattiest bits or you need to concentrate the flavor or ideally both. Either is a nice carrier for other flavors

      They shouldn't focus as much on meaty taste (as mentioned in the summary) and instead focus on meaty texture. That is the biggest resistance for myself and any heavy meat-eaters I have discussed this with (still anecdotal though). We appear to already have the technology to get the taste right, from my experience with a few different meat substitutes. But the texture is way off.

        Well, for starters those plant farms are ecological disasters as well. You are right about the texture. For the flavor... they've managed to achieve 'good enough' for low grade fast food burger with sugary dips and toppings. But they don't even remotely compare with a high quality medium 80/20 chuck patty that has been properly seasoned let alone the beef pinnacle of salt/pepper crusted prime brisket has been clean smoked Texas style for 12+hrs and had the seam fat properly rendered.

It's simply not really sustainable. There is a traditional argument for all the subsiding it gets to make it affordable pertaining to providing necessary nutrition.

        There's also cultures that live in huts and suffer from neglected diseases, too. It doesn't mean most people would want to live like that if given the choice. I'm sure if these cultures had access to meat the way we do in western society, they'd ditch the bugs too.

          Errr they do. Basically every place I've ever seen insects offered on the menu also offer something that would appease your biased view on what is and isn't eaten.

          You're begging the question with your post that postulates that people eat bugs because there's no other alternative. Heck last time I ate mealworms and grasshoppers I was tossing up between that or a smoked salmon burger. The girlfriend wasn't as keen, she had a smoked chicken burger.

          It blows my mind that people would find the thought of eating bugs disgusting while also paying a premium for shrimp. What are they if not the bugs of the sea?

              Dunno about a lot of people. I personally devein prawns, but shrimp are too small to meaningfully do that. In many places (both Asian and western) shrimp are eaten whole. And again it comes down to personal taste and sensibilities rather than what is or isn't available.

          How is this insightful? All you have said is you imply cultures which aren't different than you must be some kind of undeveloped backwater country. The second largest economy in the world has a culture where eating insects is common. Not only as bare subsistence eating, but in restaurants. I don't have statistics on it, but I wouldn't be surprised if the majority of the world's middle class is comfortable eating insects. The west does not represent the entire world.

        There were reports of people having feelings of dread or fear from iPhone models with three camera lenses, and they didn't know why. Psychologists figured it out, the lenses packed in a triangle looked like bug eyes or insect nests. Maybe this fear was learned by people being stung by an insect.

    I saw a TED Talk some time ago on how grazing animals are holding back the deserts. If this works then we could turn large desert areas into land that produce meat and sequester carbon into the soil.
    https://www.ted.com/talks/alla... [ted.com]

    I reject the notion that we "need" to eat insects to "save the planet". The "planet" survived climate change before, it is human civilization that would suffer. Even the worst predictions of sea level rise and global warming tell us the equatorial zones will continue to have rain forests and savannas. They won't really change much because they are already hit with plenty of sun, and either an abundance or absence of water. What we could do though is manage the grazing of large animals to aid in the spread of plants that can hold water and carbon in the soil. These animals will produce meat. Eating meat isn't a problem, it is how meat is produced currently.

    We can grow meat in ways that aid in reducing global warming. I say we work on that before we give up and start eating insects. There's a lot of deserts in the world we could potentially shift to grazing areas for cattle. Just huge sections of Asia, Africa, and Australia look like potential places to try.

      This is currently done in the sand dunes Nebraska and other parts of the country which would, otherwise, be desert.

      This area used to be host to massive herds of Bison and accompanying predators and so on. Disease wiped the bison out over 100 years ago, and -something- needs to roam those sands or the land quickly reverts to desert.

      Regular, infrequent (ie not over-grazing) cattle grazing has effectively prevented western Nebraska and large parts of Wyoming from turning into a continuous desert.

    • If we get to the point of worst predictions there won't be any rainforests left after the human race nukes itself to and the planet into oblivion fighting a war for resources as billions of climate refugees stress our nations.

      Make no mistake, humans suffering on a global scale will not end well for the planet.

      • The human race isn't going to "nuke itself into oblivion" fighting resource wars. That's because nuclear power is far more valuable as an energy source than as a weapon to take over coal mines and petroleum wells. Nuclear power can be used to desalinate water, then pump that water far inland for irrigation. Building nuclear weapons to take over croplands is counterproductive because the land would be contaminated with fission products for months to years.

      You are probably not getting enough leucine, it's an essential amino acid, and it's not present in whey protein. If you have protein without it, then it's as you describe: nice at first, but old after the 100th. You should either consider getting a different protein with leucine (like BSN, nice flavor [amazon.com]), or getting some BCAAs or even raw leucine [amazon.com] and adding it to your shake. I'd recommend the BSN, though, it comes with leucine.
