Eating Insects

Nothing New

While in the West the notion of eating insects make most people squeamish, around 2 billion people in the world already eat insects as part of their everyday diet. And if you think you could never eat them, well think again as you probably already have.

Insects are already present in our diet in food additives such as cochineal (E120) which is made from crushed red beetles and used as a colouring in drinks, cakes, jams, sweets, sausages, ice cream etc…

In March BBC Four aired a documentary “Can Eating Insects Save the World?” where presenter and food writer Stefan Gates travelled in Asia where eating insects is common. In Cambodia and Thailand insects are not only eaten as a delicacy but also in poorer regions eaten for survival. In some areas insects represent big business bringing profitable incomes to disadvantaged communities.

Gates explains that there are 1,900 edible species of insects. They represent an incredible food resource with 40 tons of insects available for every man on the planet. Insects are high in protein, low in fat and are about 20 times more efficient than beef at producing body mass. Insects could be the ultimate sustainable food source as they reproduce a lot, are fast growing (crickets only take 45 days from egg to fully adult size), require little water or food and produce low CO2 emissions. In bugs infested areas, insects’ “hunters” play also a major role in pest control reducing the need for pesticides and insecticides.

Solution to curbing world hunger?

In the near future we almost certainly will have to change our eating habits. The already strained current food production will need to almost double to feed the 9 billion world population estimated by 2050.

This week the Food and Agriculture Organization (FAO) of the UN presented the results of a study of the role of insects in fighting hunger and the world food crisis. The FAO points out that “globally, the most consumed insects are: beetles (31 percent); caterpillars (18 percent); bees, wasps and ants (14 percent); and grasshoppers, locusts and crickets (13 percent). Many insects are rich in protein and good fats and high in calcium, iron and zinc. Beef has an iron content of 6 mg per 100 g of dry weight, while the iron content of locusts varies between 8 and 20 mg per 100 g of dry weight, depending on the species and the kind of food they themselves consume.”

The report also argues that sustainable insect farming might provide a stable low cost protein source and a steady income for poorer Asian countries.

The future of food is a serious problem and while insects are invaluable in preserving our eco systems, their biggest contribution might just be helping the survival of the human species. But first we need to overcome our prejudice towards bugs. Personally after watching Gates’ documentary, I am curious about red ants and crickets. Who knows, as a low fat high protein food The Coleopteran Diet might be the next big thing? A good thing if you ask me, as long as the insects are sustainably sourced of course!
