Should we eat bugs? - Emma Bryce
-
0:07 - 0:09[Why don't we eat bugs?]
-
0:09 - 0:12For centuries, people have consumed bugs,
-
0:12 - 0:13everything from beetles
-
0:13 - 0:15to caterpillars, locusts,
-
0:15 - 0:18grasshoppers, termites, and dragonflies.
-
0:18 - 0:20The practice even has a name:
-
0:20 - 0:21entomophagy.
-
0:22 - 0:24Early hunter-gatherers
probably learned from animals -
0:24 - 0:27that foraged for protein-rich insects
and followed suit. -
0:28 - 0:32As we evolved and bugs
became part of our dietary tradition, -
0:32 - 0:35they fulfilled the role
of both staple food and delicacy. -
0:35 - 0:39In ancient Greece, cicadas
were considered luxury snacks. -
0:39 - 0:43And even the Romans found
beetle larvae to be scrumptious. -
0:43 - 0:45Why have we lost our taste for bugs?
-
0:45 - 0:48The reason for our rejection
is historical, -
0:48 - 0:50and the story probably begins
-
0:50 - 0:53around 10,000 BC in the Fertile Crescent,
-
0:53 - 0:54a place in the Middle East
-
0:54 - 0:57that was a major birthplace
of agriculture. -
0:57 - 1:01Back then, our once-nomadic ancestors
began to settle in the Crescent. -
1:01 - 1:05And as they learned to farm crops
and domesticate animals there, -
1:05 - 1:06attitudes changed,
-
1:06 - 1:10rippling outwards towards Europe
and the rest of the Western world. -
1:10 - 1:11As farming took off,
-
1:11 - 1:14people might have spurned
bugs as mere pests -
1:14 - 1:16that destroyed their crops.
-
1:16 - 1:18Populations grew,
and the West became urbanized, -
1:18 - 1:21weakening connections
with our foraging past. -
1:21 - 1:24People simply forgot
their bug-rich history. -
1:24 - 1:27Today, for people not
accustomed to entomophagy, -
1:27 - 1:28bugs are just an irritant.
-
1:28 - 1:31They sting and bite and infest our food.
-
1:31 - 1:34We feel an "ick factor"
associated with them -
1:34 - 1:37and are disgusted
by the prospect of cooking insects. -
1:37 - 1:40Almost 2,000 insect species
are turned into food, -
1:40 - 1:43forming a big part of everyday diets
-
1:43 - 1:45for two billion people around the world.
-
1:45 - 1:48Countries in the tropics
are the keenest consumers, -
1:48 - 1:50because culturally, it's acceptable.
-
1:50 - 1:53Species in those regions
are also large, diverse, -
1:53 - 1:56and tend to congregate in groups or swarms
-
1:56 - 1:58that make them easy to harvest.
-
1:58 - 2:00Take Cambodia in Southeast Asia
-
2:00 - 2:02where huge tarantulas are gathered,
-
2:02 - 2:04fried, and sold in the marketplace.
-
2:04 - 2:05In southern Africa,
-
2:06 - 2:09the juicy mopane worm is a dietary staple,
-
2:09 - 2:10simmered in a spicy sauce
-
2:10 - 2:13or eaten dried and salted.
-
2:13 - 2:17And in Mexico, chopped jumiles
are toasted with garlic, lemon, and salt. -
2:17 - 2:20Bugs can be eaten whole to make up a meal
-
2:20 - 2:23or ground into flour, powder,
and paste to add to food. -
2:23 - 2:25But it's not all about taste.
-
2:25 - 2:26They're also healthy.
-
2:26 - 2:31In fact, scientists say entomophagy
could be a cost-effective solution -
2:31 - 2:34for developing countries
that are food insecure. -
2:34 - 2:36Insects can contain up to 80% protein,
-
2:36 - 2:38the body's vital building blocks,
-
2:38 - 2:41and are also high in energy-rich fat,
-
2:41 - 2:44fiber, and micronutrients
like vitamins and minerals. -
2:44 - 2:47Did you know that most edible insects
contain the same amount -
2:47 - 2:50or even more mineral iron than beef,
-
2:50 - 2:55making them a huge, untapped resource
when you consider that iron deficiency -
2:55 - 2:58is currently the most common
nutritional problem in the world? -
2:58 - 3:01The mealworm
is another nutritious example. -
3:01 - 3:05The yellow beetle larvae are native
to America and easy to farm. -
3:06 - 3:08They have a high vitamin content,
-
3:08 - 3:09loads of healthy minerals,
-
3:09 - 3:12and can contain up to 50% protein,
-
3:12 - 3:15almost as much as in an equivalent
amount of beef. -
3:15 - 3:18To cook, simply sauté in butter and salt
-
3:18 - 3:21or roast and drizzle with chocolate
for a crunchy snack. -
3:21 - 3:23What you have to overcome in "ick factor,"
-
3:23 - 3:25you gain in nutrition and taste.
-
3:26 - 3:27Indeed, bugs can be delicious.
-
3:27 - 3:29Mealworms taste like roasted nuts.
-
3:29 - 3:31Locusts are similar to shrimp.
-
3:31 - 3:35Crickets, some people say,
have an aroma of popcorn. -
3:35 - 3:39Farming insects for food
also has less environmental impact -
3:39 - 3:40than livestock farms do
-
3:40 - 3:43because insects emit
far less greenhouse gas -
3:43 - 3:46and use up less space, water, and food.
-
3:46 - 3:49Socioeconomically, bug production
-
3:49 - 3:51could uplift people
in developing countries -
3:51 - 3:53since insect farms can be small scale,
-
3:53 - 3:57highly productive, and yet
relatively inexpensive to keep. -
3:57 - 4:01Insects can also be turned
into more sustainable food for livestock -
4:01 - 4:03and can be reared on organic waste,
-
4:03 - 4:04like vegetable peelings,
-
4:04 - 4:07that might otherwise
just end up rotting in landfills. -
4:07 - 4:09Feeling hungry yet?
-
4:09 - 4:13Faced with a plate of fried crickets,
most people today would still recoil, -
4:13 - 4:17imagining all those legs and feelers
getting stuck between their teeth. -
4:17 - 4:18But think of a lobster.
-
4:18 - 4:22It's pretty much just a giant insect
with legs and feelers galore -
4:22 - 4:26that was once regarded
as an inferior, repulsive food. -
4:26 - 4:28Now, lobster is a delicacy.
-
4:28 - 4:30Can the same paradigm shift
happen for bugs? -
4:30 - 4:32So, give it a try!
-
4:32 - 4:34Pop that insect into your mouth,
-
4:34 - 4:35and savor the crunch.

What's tasty, abundant and high in protein? Bugs! Although less common outside the tropics, entomophagy, the practice of eating bugs, was once extremely widespread throughout cultures. You may feel icky about munching on insects, but they feed about 2 billion people each day (Mmm, fried tarantulas). They also hold promise for food security and the environment. Emma Bryce makes a compelling case for dining on bugs.
