Which of the following agencies does not fund health research?

The National Science Foundation (NSF) primarily focuses on promoting the progress of science by funding a broad range of scientific research and education initiatives across various disciplines, including fundamental research in science and engineering. However, its core mission does not typically extend to health research specifically.

In contrast, the other agencies listed, such as the US Army and the US Navy, often engage in health research related to military needs, including studies on combat medicine or health effects of exposure to various environments. The Food and Drug Administration (FDA) also plays a crucial role in health research, particularly concerning drug approval processes and public health initiatives.

By understanding the NSF's focus and mission, it becomes clear why this agency would not be categorized as one that funds health research when compared to the other agencies listed.
