What makes our culture closer to "inherent" human nature than those 3000 cultures?
I am Danish and I eat leverpostej daily. It is minced pork liver, minced pork fat and a few other things, mixed baked in the oven.
I am sure others would say it is revolting, but I love the taste.
I also had squid. Tasted kinda rubbery, but people might say it was revolting.
I have had (and enjoyed) pig heart, it is super time consuming to make, but so, so delicious.
I have had pig cheeks as well. Also tasty.
My point with this isn't to gross anybody out, but that what we find gross is a cultural thing, not an objective thing, so there is no a priory reason we should find insects especially gross.
And yes, I have had meal-worms. Tasted like paper, but the nutritional ratios are a dream: 53% protein, 20ish percent fat, almost no carbs.
For fun my wife made some cookies including cricket powder. We told people and did not hide that fact from them. Most wanted to try it for the novelty of it and didn't find the idea disgusting.
Ahh laws and sausages ;)
This is not to say, primates wouldn't eat snakes or spiders. I don't know if other primates eat them (they might be?) but humans do eat both [3] [4].

It really isn't that hard to explain. It's the same reason we don't eat rats. They are considered "unclean".
Human culture comes in all sorts of shapes and beliefs. The moment you try to put it into cups, you'll realize it's not as flexible as you thought. There are thousands of cultures that eat insect, or pig; and as many cultures that consider them unclean.
