Health guidance will become politicized
Whatever the thing is that homogenizes opinion in all of: corporate news media, mainstream entertainment, three-letter-agency guidelines and pharmaceutial business interests - this thing is going to become hostile to healthy lifestyles.
This mindshare complex will give advice that is the opposite of whatever you should do to be healthy. And given that this complex is highly aligned with the Blue Team of American politics, anyone seeking to improve their health will be cast as Red Team members - often unfairly.
Many similar topics are needlessly politicized in this manner. I suspect human health will be the next to fall.
Update on 2024-11-12: Two months after my prediction, the NY Times (a deep blue team player) is right on schedule: link to article archive. Not only is much of this article in conflict with high-quality nutritional science, but it needlessly politicizes the topic: "Robert F. Kennedy Jr. and others claim [seed oils] are harming our health, but the evidence suggests otherwise".
