I don’t eat bugs. Not in a significant self-aware way, at least. But there are many good reasons to. I want to list the reasons I find most compelling—mainly as an exercise of pre-emptive self-persuasion. So that when I am confronted with a bowl of crickets, I can use these reasons to help me to overcome my culturally-constructed food avoidance.
In other words, I will use reason to get over the gross-out.
By the way, there’s a word for bug-eating. It’s “entomophagy…” an ugly stuffy-sciency word that’s another barrier to overcome.
One big reason eat bugs involve feed conversion rates. It’s well known how unsustainable current animal protein production is. However, compare this to insect protein production.
For example, if you take 10lbs of feed, it gets you the following conventional animal protein:
5lbs of chicken
3lbs of pork
1lb of meat
However, if you take the same amount of feed—10lbs—and give it to crickets, you get…
That’s so much protein!
Since bugs are cold- blooded, they are much more efficient at converting feed to meat than their warm-blooded buddies…which have to waste energy keeping themselves warm.
From sustainability point-of-view, the advantages are clear. You get almost twice as much insect protein from the same amount of feed than you would from chicken. You get 9 times as much as you would from a cow.
With increasing population rates, this type of food source could be a reliable and efficient protein source. It’s already happening in Thailand.
However, is this enough for entomophagy (or better… maybe call it “land-crabbing”?) to take off in the US? Although it’s a lot of crickets, they are still crickets.
Although, I haven’t (knowingly) eaten crickets yet (can’t wait!), the efficiency of their production is a good reason.
