According to the FDA, "Health claims describe a relationship between a food, food component, or dietary supplement ingredient, and reducing risk of a disease or health-related condition".
In general, claims of health benefits for specific foodstuffs have not been evaluated by national regulatory agencies. Additionally, research funded by manufacturers or marketers that may form the basis of such marketing claims has been shown to result in more favorable results than independently funded research.
Taiwan is a tilted fault block, characterized by the contrast between the eastern two-thirds, consisting mostly of five rugged mountain ranges parallel to the east coast, and the flat to gently rolling plains of the western third, where most of Taiwan's population reside. There are several peaks over 3,500m, the highest being Yu Shan at 3,952 metres (12,966ft), making Taiwan the world's fourth-highest island. The tectonic boundary that formed these ranges is still active, and the island experiences many earthquakes, a few of them highly destructive. There are also many active submarine volcanoes in the Taiwan Straits.
