Hi!
Am I back too quickly ?
Yes I am, because I have something novel to share!
You may find this post is unbelievable, yet it's true that the world starts embracing a new sort of food source. This can be a no way for certain people. Nevertheless, this is what our future is facing as we need to eat every day regularly. Probably, some countries are common with what I'm going to share today, because it is massively produced even every single day. On the other hand, some countries would think it is something not worth consuming.
Today, I'm talking about insects as our future food prospects

As I have said before, some parts of the globe have already been common to consume insects. Whereas, some other think that consuming insect is a taboo activity. This eating-insect activity is usually called entomophagy. First thing first, I'd like to define what insects are. Insects are a class of animals, categorized in the arthropod group that have a chitinous
exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs,
compound eyes and two antennae. Insects have existed since millennia ago and been helpful for human as they produce some valuable products for human's life, for example honey (from bees), silk (from silk worm), carmine (color additive from Hemiptera bugs), and some medical remedies.
According from Food and Agricultural Organization (FAO), there are some major groups of insects that are used to be consumed, e.g. Beetles (31%); Caterpillar (18%); Bees, Wasps, and Ants (14%); Grasshoppers, Locusts, and Crickets (13%); and some other more. Only few documents have successfully reported the countries that have consumed insects long time ago. People in Republic of Congo consume caterpillars during rainy season, in which caterpillars play essential role to maintain food security as fish and game are hardly to hunt. Moving to Asia, especially South-East Asia, people of Laos, Myanmar, Thailand, and Vietnam are used to consume insects as they can collect the insects throughout the year from a various range of habitats. Last but not least, let's fly to Latin America, where people there have deep knowledge about insects, of which they believe that insects have particular connection with natural phenomena. In Mexico, chapulines are harvested in rainy season; in Columbian Amazon, snout beetle are hunted during rainy season; and in Ecuadorian highlands, Platycoelia lutescens beetle are available in markets during winter.
Now, let's take a look on how nutritious insects are. Most nutrients found in insects are protein, fats, and fiber. Nonetheless, the amount of nutrition happen to be in insects are various based on their habitats, feeds, and some are related to their metamorphosis steps.

Now, let's take a look on how nutritious insects are. Most nutrients found in insects are protein, fats, and fiber. Nonetheless, the amount of nutrition happen to be in insects are various based on their habitats, feeds, and some are related to their metamorphosis steps.
1. Proteins
Protein contained in insects can be in a range of 7 - 48 g (/100g fresh weight), depending on species and their morphology. While, fish and cattle have around 13 - 28 g (/100g fresh weight) of protein. This means, that insect can be a complementary protein source when including animal source protein.
2. Fats
Insects are good sources of essential fatty acids, such as linoleic
and α-linolenic acids. Overall, insects may contain approximately 9 - 67% of fats (% of dry matter), which most of them are mono- and polyunsaturated fatty acids.
3. Minerals and Vitamins
Some minerals, like potassium and sodium can occur in high amount in insects. Moreover, zinc and iron are present as minor minerals, yet can cover the recommended dietary allowances. Meanwhile for vitamins, insects are rich in vitamin B complex, e.g. thiamine (B1), riboflavin (B2), and cobalamin (B12).
4. Fiber
Fiber source found in insects is due to its chitinous exoskeleton, which chitin is recognized as crude fiber. This fiber is approximately 2.7 - 49.8 mg (/kg fresh weight).

I do want to share more about these insects, yet I think it's quite enough for now.
I don't want to make a very long post, because this should be a fun reading and learning, not something so boring with many texts appear on your screen.
I hope this is meaningful to you, and see you in my next post!
