The reasons are truly many, edible insects are in fact:
- Highly protein-rich: in the case of crickets for example the percentage of complete proteins reaches up to 77%, i.e. 2 or 3 times higher – for the same weight – than that of red meat.
- Rich in micronutrients: such as minerals and vitamins including vitamin B12 – essential for an immune system and a healthy brain.
- At the same time they have a very low environmental impact: raising crickets, for example, leads to a reduction in greenhouse gas emissions equal to 99% when compared to cattle farming¹.
Not only that, insects are also very skilled at transforming plant waste into high-quality nutrients. The same goes for food and natural resources, just think that to produce one kg of beef you need 15,000 liters of water and 200m² of land; 10 liters of water and 15m² of land are enough for one kg of crickets.
