Edible insects such as caterpillars and grubs should be considered an alternative source of nutrition in the effort to overcome food insecurity in central African countries, a new study by the United Nations food agency has said.
"Edible insects from forests are an important source of protein, and unlike those from agricultural land, they are free of pesticides," said Paul Vantomme, a forestry expert of the Food and Agriculture Organisation. He noted that caterpillars are already an important food intake for many people in central Africa.
More than 90 per cent of participants in a survey in Botswana said they consumed caterpillars. Over 85 per cent in the Central African Republic and 70 per cent in the Democratic Republic of the Congo said they do the same.
Every 100 grams of dried caterpillars has 53 grams of proteins, about 15 per cent fat and about 17 per cent carbohydrates, according to the study.
"Due to their high nutritional value, in some regions, flour made from caterpillars is mixed to prepare pulp given to children to counter malnutrition," said Vantomme.
"Contrary to what many may think, caterpillars are not considered an emergency food, but an integral part of diet
in many regions according to seasonal availability. They are consumed as a delicacy.
"The nutritional and economic value of edible insects is often neglected and we should further encourage their collection and commercialisation, given the benefits to the environment and human health," said Vantomme.
