The plates of our dinner may need to be modified. The delicious burger you wish to have might be made of proteins from cows and crickets, mealworms, and black soldier flies. While entomophagy, the consumption of insects as food, may, to some people, sound like something from a future trend, it is potentially a game changer, enabling food production in a manner that is healthier and also eco-friendly.

On the same token, while livestock farming, a major protein source for us, carries a significant environmental burden, insects offer a promising solution. They present a highly efficient and sustainable food alternative, leading to substantial land, water, and feed savings compared to beef cattle while maintaining nutritional value. Bursting with proteins, essential amino acids, vitamins, and healthy fats, these tiny creatures are a complete protein source, a true gem that can help us create balanced diets worldwide.

Protection by insects, but what are we talking about? Are the ingredients sourced ethically and free from exploitative practices? How are they cultivated and manufactured?

This blog will take you beyond the weird to understand the world of insect diets and how they might transform the food system. Starting from the advantages, we will highlight the insect protein’s contribution to the environment via the end of the environmental footprint and the utilisation of the resources more efficiently; we will also present the nutritional value in the end. Rest assured, the insect farming industry is committed to ethical practices, ensuring the well-being of the insects and the sustainability of the environment.

Nevertheless, there are initial doubts, while the promising advantages are clear. Educating consumers by creating awareness and through innovative product development can make insect protein a regular food in our daily meals.

What are insect proteins?

Insect proteins, derived from various insect species such as crickets, mealworms, and soldier flies, are not just a source of calories. They are a nutritional powerhouse, providing all nine essential amino acids our bodies need to function. They are rich in vitamins, minerals, and healthy fats. For instance, crickets contain more iron than spinach and a comparable amount of vitamin B12 to beef liver, illustrating their nutritional value.

Processing insects into products that can be eaten in various forms. Can cricket flour or pasta be made from the flour of insects, or mealworm powder for shakes? And the whole roasted insect—is it the crunchiness? Those possibilities are endless, and you had better be ready to contend with them because they will ultimately never stop changing.

What are the benefits of insect protein?

The potential benefits of insect protein are numerous and compelling, particularly when compared to traditional livestock farming:

  • Environmental Sustainability: Contributing to greenhouse gas emissions, deforestation and water contamination, livestock production is an essential environmental problem. To illustrate, insects are the other section of animal species whose production of the same amount of protein doesn’t need large amounts of land, water, and feed. Crickets, in particular, use no more water or feed than those who would be fed to cows for meat. This significant reduction in the environmental footprint of food production is a key environmental benefit of insect protein.
  • Reduced Waste: Insect farming uses food by-products to feed insects, and closed-loop systems are promoted to reduce waste in the overall ecosystem. Black soldier fly larvae, for instance, can decompose organic waste while converting it into one source of proteins. This innovative approach to waste management is a key environmental benefit of insect protein.
  • Scalability and Efficiency: Insect barns have a vertical stack that takes up little space; hence, a high-density production can be hosted in these skyscrapers. Also, they reach maturity very quickly and can produce numerous progenies quickly; thus, they are adaptable and efficient protein resources for the increasing population. This scalability and efficiency make insect protein a promising solution to global food security.
  • Nutritional Powerhouse: As mentioned before, insect protein is a versatile protein source because it contains substantial amounts of essential nutrients. For example, crickets contain more iron than any ordinary spinach, and even its amount of vitamin B12 is comparable to that of beef liver. This makes them a significant dietary element, especially in places where there is malnourishment or protein scarcity.

Understanding the Edible Insects

Though new to certain individuals, the concept of insects as potential foodstuffs is nonetheless ancient and has a colourful history. More than 2000 edible insects have been identified worldwide, and among them, Southeast Asian nations, African nations, and Latin American nations practice insect eating most prevalently. This long-standing cultural acceptance of insect consumption underscores its potential as a regular food in our daily meals.

Here’s a closer look at some of the key players in the insect protein industry:

  • Crickets: Crickets are the most maintained insect due to their high development rate and low flavour. They can either be roasted “as is” or ground to a powder for different uses.
  • Mealworms: One of the insects most sold for human consumption is Tenebrio molitor beetle larvae, also known as mealworms. Their high fat and protein levels make them unique in that they can be incorporated into many food dishes.
  • Black soldier Flies: Despite the fact that black soldier fly larvae do not directly contribute to the diets of human beings, they are of utmost importance in our waste management and waste-insect protein production process. They work effectively with organic waste disposal and can be converted into valuable protein feasts for animal or fish farming purposes.

Breeding Edible Insects

Insect farming, unlike traditional livestock, requires minimal space and resources. Breeding facilities can be located indoors, vertically stacked, and often constructed using recycled materials. The breeding process is generally controlled and efficient, with insects fed carefully monitored diets that optimise their growth and nutritional value. This efficient process and the minimal space and resources required for insect farming make it a sustainable and eco-friendly food production method.

Here’s a simplified breakdown of the insect breeding process:

  • Egg Incubation: Insect eggs are incubated under controlled temperature and humidity conditions to ensure optimal hatching rates.
  • Larval Growth: Hatched insects are reared in containers and provided with a specific diet to promote rapid growth.
  • Harvesting: Once mature, insects are harvested using humane methods, such as freezing or carbon dioxide stunning.
  • Processing: The harvested insects undergo processing, which may involve drying, grinding, or extracting oil for incorporation into various food products.
  • Innovation and Regulation: As the insect protein industry grows, so does the focus on innovation and regulatory frameworks. Companies are constantly developing new technologies for efficient insect farming and processing.

Additionally, regulatory bodies are working to establish clear guidelines for insect protein production and consumption to ensure food safety and consumer confidence. This commitment to innovation and regulation ensures insect protein is a safe and high-quality food source.


The concept of insect-based protein may sound strange to some at first, but the benefits are indisputable. From environmentally friendly to inexpensive resources and nutritious dietary, insect protein offers a solution to the crisis of feeding the rapidly increasing world population. As we see higher customer acceptance and legislative constraints, insect-based food items may soon be one of the key players in our diets, promoting a more stable and nutritional food structure for everyone.

Overcoming Challenges

Even if the insect protein industry does have many benefits, it still has obstacles. At the same time, we face the main problem of consumer opinion. Overcoming “Natural Aversion” to insects necessitates awareness creation and dissemination of innovative products. It is essential to exhibit how diverse and tasty mealworms can be when used in our diet; therefore, they can already be considered an effective instrument for experience conversion. Regarding it, strict standards of safety and open labelling will compel the consumers to trust the product.

The Future of Food

The future of food is going to be quite a busy space, and we can be sure that plant foods and beyond will include insect protein. Partial solutions, mixed with insects into other food types, may further draw in popularity and enlarge the diversity of the consumer market. Insect farming and processing with newly developed technology certainly lend themselves to a more efficient and affordable means of food production.

The efforts to transform what people previously called “the bugs to burgers” are not the slowest. The adoption of insect protein is not only sustainable but also an informed decision toward the well-being of the planet and sustainable food production. Through open minds and a sense of adventure in tasting new types of cuisines, we can find the benefits that this type of food can have for the environment and finally realise a better life for generations to come.
