Which organization primarily conducts research on non-infectious diseases like obesity and diabetes?

The Centers for Disease Control and Prevention (CDC) is well-known for its focus on public health and safety, particularly in the areas of disease prevention and control. While it plays a significant role in addressing infectious diseases, it also has extensive initiatives dedicated to non-infectious diseases, including obesity and diabetes. The CDC conducts research, provides resources, and develops public health campaigns aimed at mitigating the impact of these diseases on the population.

The other organizations mentioned have different primary focuses. The World Health Organization (WHO) addresses a broad range of health issues globally, but it does not concentrate specifically on non-infectious diseases. The National Institutes of Health (NIH) does conduct research on a variety of health issues, including non-infectious diseases, but its primary role is in funding and supporting biomedical research rather than directly addressing public health concerns like the CDC. The Food and Drug Administration (FDA) is primarily responsible for regulating food and drug safety, rather than conducting research on diseases. Thus, the CDC is the most appropriate choice when it comes to organizations that conduct specific research and initiatives targeting non-infectious diseases.
