True, but people who tend to prioritize personal health also tend to be richer than the average bear.
High quality, healthy food is much more expensive per calorie than hyperprocessed, high calorie/low micronutrient, carcinogenic food. Gym memberships are pretty expensive, even without any of the personal coach and flex location fluff. And for someone with a lower paying job, time is more scarce as well, in addition to the job itself likely being more harmful to health. And of course, health care is expensive, and even if you live somewhere with socialised medicine, access to specialists is a lot easier and more expedient if you can afford to pay extra.
It's not like poor people don't care about their health, they just have fewer options and less time to spend on it. I support anything that can bring more options to more people.
Largely true, but frozen vegetables are inexpensive. And they are healthier than fresh vegetables. Veggies are the key to good health for the poor.
