When my son was young he had an extremely hard time with a lot of food textures and developed anxiety when he was prompted to try new foods. There wad a lot of vomiting/gagging and crying. We tried many forms of positive and negative reinforcements and tactics to get him to try new things, which at best resulted in small, incremental developments. Now, at age 11, he will at least try most foods but has some odd aversions (for example, cooked/steamed vegetables. He can only eat them raw without gagging).

My question is; is this sort of aversion common in societies that are less food secure? I have a hard time thinking that a child from a culture with less food security would refuse or gag at porridge if it was the only thing available. I've also heard in documentaries about the Great Depression from people who had to eat all manner of things we may consider inedible/undesirable today. It got me wondering whether food security can lead to picky/selective eating.
