That's simply not true. The UN FAO estimates that 2B people worldwide consume terrestrial insects regularly in their diets. Add in aquatic insects like shrimp or lobster and that number increases drastically.
There's a strong cultural component when it comes to disgust. People in many parts of the world eat insects regularly as a part of their standard diets. In the US, most people don't think of honey or lobster (aquatic arthropod) or carmine (red food coloring) as "insect food" but these items most definitely fit in that category and are commonly consumed.
In the past, people in the west found yogurt, sushi, and lobsters absolutely disgusting. Now many will happily eat those foods, and even consider them delicacies.
Some disgust reactions are hard-wired (e.g. reactions to fecal matter or vomit), and others are culturally learned.
Good thoughts. There's a lot to be added and improved upon - this is just the beginning. We're planning to incorporate all of the above, so this feedback helps.
