Some unexpected properties of edible insects : good for the mind, the body and heart?

Now, there are more and more information about the nutritional values of edible insects. It’s start being well known, that insects are a good source of proteins, vitamins and minerals. But what if edible insects have also some unexpected properties? The growing interest about edible insects is starting growing, scientists are beginning to discover some unexpected properties.

What a good way for starting the year 2016 with some good news for our heart, brain and body! Peace, love, health and crickets for you and your beloved ones!

Some unexpected properties of edible insects

With the growing interest about edible insects from the public, the scientific community and the media, the number of studies are growing.

As we are starting understanding the importance of edible insects, we are, at the same time discovering how little we know about the subject. What could we expect from a field crossing entomology, nutrition, environment, food history, cooking, anthropology, health, psychology, sociology and marketing?

So what are these “unexpected properties”? Naturally, we need to be cautious because for the moment the litterature is still scarce but everything has a beginning…


Edible insects ; good for the mind

In 2014, a group of Korean scientists were searching natural therapeutic compounds for Alzheimer disease. For this purpose, they studied the mealworm larvae. They discovered that the fatty acids in the mealworm contain a substance used for Alzheimer disease treatment.

It’s clearly a good news because, at the same time, the University of Wageningen in the Netherlands is examining the use of edible insects as a sustainable source of the essential Omega-3 fatty acid, which is also useful for our brain function. So, why not combine everything? Edible insects are definitely a food for thought…


Edible insects ; good for the heart

As I wrote in Jimini’s blog, the scientific journal PlosOne published an article in May 2015 called “Potential of the Desert Locust as an Unconventional Source of Dietary and Therapeutic Sterols”. The head researcher of the study,Baldwyn Torto, explained that the sterols contained in the locusts can lower the level of blood cholesterol, which can be beneficial for the heart and against cardio vascular diseases.

This beneficial compound is naturally present in different plants like wheat. As locusts are feeding on wheat, they are able to metabolize it. Another compound found in locusts could improve our synthesis of the D vitamin, which we often lack and which is provided by the sunlight. Let edible insects make our heart beat and shine…


Edible insects ; good for the body

And that’s not finished yet… In 2000, some Japanese scientists discovered that the silkworm’s protein elevated the intestinal absorption of zinc, iron, magnesium and calcium in rats. These results could be interesting if they were verified on humans as the modern diet often lack these nutrients.

The sericin, this protein produced by the silkworm, has definitely shown some potential: In 2010, it has been discovered that it also has the potential of lowering the cholesterol level. Isn’t it exciting?Edible insects, good for the heart, the mind and the body.

Are these discoveries really surprising? Seriously, what did you expect from the most successful, abundant and diverse animal creatures on earth?

Some not so-unexpected properties of edible insects

Is it really a surprise? Maybe not… Insects were and are eaten by our ancestors from the beginning of humanity, too the paleo period, until nowadays. Not only as food for their nutritional values, but insects were also valued as medicines for some therapeutical properties. Is it really surprising, coming from the most successful, numerous and diversified creatures of the animal kingdom?

As my friend the Dr. Benno Meyer-Rochow wrote in several studies, edible insects were also and even sometimes mainly more appreciated for their therapeutic values than for their nutritional values. Nowadays, these practices are still common in severals parts of China, Korea, India and in some hunters and gatherers tribes.

It is true that some of these usages of edible insects are coming from folk logic and come more from beliefs than proofed facts. As an example, the cicada can be eaten for treating hearing whereas the eggs of praying mantis are eaten by men for fertility.

On the other hand, insects contain also some biologically active chemistry. For example, the social insects that live in close proximity, such as wasps, ants or bees, developed antimicrobial compounds for avoiding epidemic diseases. Insects living in the soil are subject to microbial attack, they should produce some chemicals to fight these attacks. And as we saw for the locusts, insects can also metabolize the compounds of their feed.

According to an Indian tribe belief, the consumption of a specie of long-horn beetle could be responsible of hair loss.


Are edible insects a real “super-food”?

I don’t think so… That’s a good point because, finally, we don’t need a new “super-food” and moreover there are so many different species and varieties of edible insects… But we simply need to be more aware and find again a contact with our food. For so, we need more food good to eat for our bodies and palates, and at the same time which is also “good to think” for nourishing our minds and hearts. And that’s great because edible insects are simply that. And as edible insects will nourish us, we will maybe more aware of them and be more interested by these animals. Imagine one day, with our appetite and interest for insects, we will maybe discover that mealworms are able to recycle styrofoam

Formerly I'm an environmental engineer, personal trainer, fitness nutrition specialist and "Entotarian". In the edible insects industry for five years, I've been consultant for an insect farm, free-lance writer and international speaker .Now in Shenzhen with Livin farms developing the world's first table-top farm. I would say that my life revolves around eating insects.
