8 (arbitrary) Levels of Societal Health

shift from nomadic hunting/gathering to settled farming
cultivation of grains; high carbs and low diet diversity led to many health issues and dental problems
nutritional deficiencies led to an 5-6 inch drop in height for males and females
higher levels of infectious disease due to higher population density and raising livestock, which led to sanitation issues
health decline from Level 1

improved sanitation from Level 2 and advancements in medicine to treat some of the health issues in Level 2
more food diversity due to trade and cities
socioeconomic inequality as a result of hierarchies led to resource inequality, which led to the rise of starvation and obesity
some people were healthier than Level 2 due to varied diet while others (the rich) gorged on food while the poor sometimes starved or had to get by on bad food, so Level 3 was not significantly healthier than level 2

similar to Level 3 but less socioeconomic inequality so more people had access to decent food
more crowding causes sanitation issues and disease spreading and infant mortality
rise of sugar and tobacco consumption
again, improvements in health are debatable from Level 3 to Level 4

most obvious decline in health in human history and worst point health-wise
corrupt and corporate greed; people are working the entire day for barely enough food to survive
more reliant on low-quality processed foods, sugars, and grains
industrial work has exposure to toxic chemicals
severe overcrowding and sanitation issues leads to more disease

present-day “developed” countries
massive improvements over Level 5 in possible health due to access to fresh healthy food for a large portion of society
social reforms and health reforms great help health care
however, WITHIN this time-period (roughly 100 years for America early 1900s to present day), health sees declines despite economic growth; vaccinations, treatments, and drugs artificially extend life and increase life expectancy greatly
processed foods and sugars, sedentary lifestyle, lack of sunlight, increased stress, more toxins, nutritional deficiencies lead to increased diseases like diabetes and cancer, more mental issues, and behavioral conditions like ASD and ADHD
we have the capability to do so much more

mainly Nordic countries
high GDP due to natural resources creates more available healthcare, less stress, better education, more regulation
culture promotes healthy diets, physical activity, social cohesion, nature exposure (according to Gemini)
it’s not extremely different from Level 6; the population as a whole is healthier due to culture
Nordic countries, although not the longest lived, is arguably uncontested for the healthiest countries; many Asian countries have longer life expectancies. However, Nordics are much larger and geographically, don’t have the capability to get nearly as much sunlight as countries closer to the equator. For them to make up these two crucial factors and be almost the longest lived, their lifestyles likely are significantly better.

completely awareness of everything that goes in your foods and products (heavy metals, aluminum, xenoestrogens, pesticides) and wide availability of clean goods
fruits, vegetables, and animal products with restored nutrients (subsidizing supplements can be an easier way)

diversion of billions of dollars of funding for R&D and treatments of preventable diseases (which would be minimal) into generally considered inevitable diseases, like aging, as well as unconscious health, like EMFs and prenatal ultrasound
preservation of nature throughout the country - especially in urban centers
cultural values and morals that decrease stress and promote satisfying lives and social interaction
clean air and water (subsidizing personal water and air filters can be an easier way)
high levels of health education
