Even now, world health authorities are discussing ways to harvest insects on a massive scale, to help combat future food shortages as world populations continue to grow. Insect harvesting isn’t for everyone, though. But it is worth taking a look at.
Edible House Flies
Rather than attempting to catch insects in the wild, it is best to breed them at home, as attempts to catch them in the wild can cost a lot of precious time and energy, and issue in disappointing results. Fortunately, technological developments are currently underway which allow entomophagists to breed insects in the comfort of their own home.
This breeder in particular promises that “one gram of black soldier fly eggs can yield 2.4 kg of protein over a 432-hour period.” This is part of what makes insects so valuable a food source.
In addition to acquiring many of the same nutrients one does when consuming more conventional meats, insects provide us with a superior feed to conversion ratio. That is, it is much cheaper to feed insects and provide them with an environment in which they are able to flourish than it is cows or pigs.
Edible Maggots – Nutritional Content Of A Maggot
In addition to containing various amounts of fatty acids, amino acids, protein, fat and energy content, the larvae of the common housefly( Musca domestica), more commonly known by the unflattering moniker “maggot”, sports a whopping 2,010 mg of calcium per 100g of insect dry matter.
Since the RDA (Recommended daily allowance) for the average adult is only 1,000 mg of calcium, this means that a serving of 100g provides over twice as much as the average adult needs to be healthy!
The same amount of insect dry matter also provides around 1,320 mg of phosphorus. Teenagers require around 1,200 mg of phosphorus, and the average adult requires around 700 mg, so either way, consuming 100g of common housefly larvae dry matter should eliminate any worries one might have about deficiencies in these vitamins(unless of course you have some sort of medical condition which requires one to take a great deal more than this).
Housefly larvae also contains an astonishingly high amount of iron. At 60g per 100g of insect dry matter, such a serving far exceeds the RDA of the demographic most in it of it: pregnant women. The Linus Pauling Institute recommends 27 mg of iron for pregnant women a day. Male teenagers require 11g, and adults, 8 mg. Female teenagers typically need 15 mg a day and adults, 18g.
At 24 mg of zinc, housefly larvae provide more than the daily required amount for all demographics. Your typical teenager-to-adult needs between 8 and 11 mg a day, with an RDA slightly higher for pregnant and breastfeeding women. Furthermore, the insect contains 6 mg of manganese, more than the daily required amount of around 2 mg for your typical teenage-to-adult demographic.

Conclusion
Of course, proper preparation of insects is essential, as consumption of any insect is associated with all of the same potential hazards as the consumption of any meat, such as parasites, microbes, contaminants, and so on.
It is beyond the scope of this article to provide such instructions, as unfortunately, such research is preciously scarce on the subject, and it is precisely the aim of writing on this subject to spur more research into ideal methods of breeding, preparation and consumption. Even with little data available for people interested in harvesting insects, manufactures are producing insect farms for flies and maggots to be raised right at home.
In light of the nutritional potential insects have for the developing world and combating food shortages, my hope in writing about the nutritional content of insects is to help erode cultural taboos toward insects, with the result being that more research is undertaken to determine ways to cultivate insects for breeding, preparation and consumption.
Editors note: As it relates to survival, relying on unusual strategies like using insects for food may become necessary once your typical survival food runs out – after all, one can only make and store so much hardtack and pemmican before you run out of storage space (or patience).

Why You Can Trust Us
Secrets of Survival has been around since 2002 (almost 20 years) and our survival knowledge is the real deal. We were writing and discussing survival and prepping before people even knew what the word “prepping” meant. We also preceded the trendiness of survival media nowadays… for example, we were arround before Bear Grylls filmed his first episode of Man vs Wild.Our contributors and writers over the years have included survival experts of all stripes – including a Green Beret Special Forces Medic, a former Navy SEAL, a leading survival instructor who’s been featured on National Geographic and PBS. Every article is either written or reviewed by someone who is an expert in either survivalism, prepping, or homesteading (or all three) and our goal is to be as practical and educational as possible.
While some of our writers and contributors use pseudonyms in order to protect their privacy (never a bad idea in these times where out of control surveillance is a growing problem), you can trust that everybody who gets to write for us has been vetted for their knowledge and passion when it comes to survival.

In many parts of the world, entomophagy, or eating bugs is commonplace. Insects are actually the most abundant protein source on the planet, and many of them boast dense concentrations of nutrients like omega. If two billion people can invite insects to the dinner table, it shouldn’t be too much of a stretch for you to include edible bugs in your emergency-survival diet.
