While increased income and wealth can have a positive impact on health, it is not a mechanism through which education directly influences health. Education can lead to increased income and wealth, but it is the knowledge, skills, and behaviors acquired through education that directly impact health.

Randomized controlled trials are the strongest type of evidence because they allow researchers to control for confounding variables and isolate the causal effect of education on health.

Higher levels of education are generally associated with lower rates of obesity, not higher rates.

The relationship between education and health disparities is complex and varies depending on the specific health outcome and population group. In some cases, education can reduce health disparities, while in other cases it can increase them.

All of the above are valid policy implications of the relationship between education and health.
