昆虫汉堡、蟋蟀比萨——听到这些“新鲜”菜式的名字，你是垂涎欲滴还是脑袋发懵？不论你接受与否，虫子这种不同寻常的食材已在世界各地流行起来。随着人口增长，人们已经开始寻找含蛋白质等营养物质的可替代食品资源，有越来越多的企业也借此潮流探索全新的商业机会。

 

Feeling hungry? How about some worms with your spaghetti? Perhaps some ground cricket to sprinkle on your pizza? Or maybe just a good old bug¹ burger?

 

While the idea of eating insects disgusts many, don't be surprised if you find creepy-crawlies on your own plate before long.

 

Why? Because insects could hold the key to the challenge of feeding the world's growing population. With the number of humans on the planet expected to reach 9 billion by 2050, the search is on for alternative sources of protein beyond the traditional meat and fish.

 

Insects are not only high in protein, but also minerals and amino acids, according to Shami Radia, co-founder of Grub, a company which sells edible² bugs³. "Insects are the original superfood," says Radia.

 

Environmentally, insects produce less greenhouse gas, use less water and take up less farmland than conventional livestock⁴ farming, meaning they have a smaller impact on the planet.

 

So if they're good for the environment and good for you, why aren't we eating insects? In fact, in many places we already are. It's estimated that two billion people around the world eat insects as part of their diet. But most Western nations have not yet adopted the practice.

 

It's the "yuck factor" that stops them from eating bugs, according to the Waste and Resources Action Programme. People in the West generally view insects as unclean and carriers of disease. They're seen as pests: they damage crops, destroy furniture and live in dirty places.

 

But perhaps attitudes are slowly shifting. Certain types of insects are becoming more palatable⁵ to consumers, such as locusts⁶ and grasshoppers⁷. Nick Cooper sells insects as food through his UK company Crunchy Critters, and has seen a sales growth rate of 25% year on year. He believes young people are more open to eating insects.

 

Shami Radia believes that munching⁸ bugs will one day become as popular as eating sushi. "Behaviour can be changed," he says. "Prawns⁹ are ugly and taste delicious and there's no reason why eating insects can't be normalised."
