This idea that eating whole food plant based is hard and time consuming is a myth. Almost every veggie cooks unattended in the microwave in about 10 minutes, potatoes included.
Since I didn't have the budget for highly processed things, I inadvertently ate super clean.
So this has me thinking, there are already complex distribution channels for medicine for places in need; to that could be added a few key supplements like B12. As long as they are getting otherwise the main macronutrients met, it becomes easier for more people to eat WFPB, which in fact like me in times of poverty many people already do.
Insects are popular in places where meat is still relatively scarce/expensive. I'm sure it's a great source of protein if you are in need of protein and there's nothing else around. However, I prefer to eat things because they are delicious. I could probably feed myself on a shoe string budget by giving up most of the things I enjoy eating/drinking. But why would I want to?
The trick is going to be feeding 11 Billion people in a way that is actually enjoyable. Insects are going to be a hard sell to someone who can afford a steak. On the other hand, shrimps, lobsters, etc. are just under water insects (or at least closely related). I don't particularly enjoy them but for lots of people they are kind of a delicacy and a completely normal part of their diet. A lot of these kind of things are learned behavior.
Science giving us options is a good thing. But I'd say they need to focus more on the eating experience than on just the protein content/nutritional value. Things like texture, juiciness, umami, maillard reaction etc. All the reasons people like steaks basically. The kind of things that get foodies excited.
