Hive minds and their swarms of drones are one thing, but why again does stuffing your face with lots of snacks result in higher population growth in a post-industrial society? If anything, eating a lot lowers life expectancy.
And the usual caveats about realism do not apply here. I am not aware of any trope in any science fiction I have ever seen or read where eating lots of food results in population growth. That is not a science fiction trope. That is a silly video game convention that as far as I know was invented by Sid Meier for Civilization I and has been blindly copied again and again ever since.
Food availability only drives population growth in the most primitive of conditions. After that, it becomes much more about the availability of medicine. Beyond that, and once birth control exists, population growth is entirely driven by social factors such as religion/ideology, female literacy and education, the profitability of children for labor, and the availability of social safety nets such as pensions in old age. A society that is missing out on population growth because of food shortage has no business traveling to the stars. It does not even deserve the stars.
