Sorry, wasn't specific - and yeah mostly stuff like Pacaso, timeshares, and REITs all deincentivize the creation of low income housing and decrease affordability. This is mostly a personal view, but second home ownership should come with serious costs.
I absolutely agree - sugar is definitely the issue. Most individuals don't get enough healthy fats due to marketing tactics. Stuff like Omega 3s and general unsaturated fats are incredibly important for brain function, reparation of tissue, etc.
