In addition, insects are a real energetic concentrate: they have a lot of nutrients, a very high protein content, as well as vitamins, minerals, essential fatty acids ... To be healthy, the human body needs a daily protein intake, since it can not make them alone: insects are full of proteins. For example, 100g of crickets cover half the protein requirement of an adult weighing 70kg, and contain 3 times more than beef at equal weight. Crickets, like many insects, have many vitamins, such as vitamins B1, B2 or B3, necessary for proper muscular and nervous function, essential in the transformation of food into energy, or in the formation of red blood cells for example . They are also filled with minerals, such as calcium, iron, zinc or phosphorus, to name a few.
In addition, the fiber content of insects is much higher than that contained in meat, and their lipid content is very low (less than 5%), making it a particularly healthy source of natural food, when we pay attention to his line, or his health. In addition, insects are also full of good fatty acids (which the body is unable to manufacture), which is a very valuable nutritional quality.
