Abstract

breadfruit artocarpus altilis artocarpus mariannensis fruit vitamin A β-Carotene α-Carotene Marshall Islands vitamin A deficiency traditional knowledge Indigenous foods ethnography HPLC food analysis food composition biodiversity and nutrition
Vitamin A deficiency (VAD) and non-communicable diseases including cancer, heart disease and diabetes are serious health problems in the Republic of the Marshall Islands (RMI), a small island nation of the Pacific. These health problems are related to the trend towards over-consumption of unhealthy imported processed foods and neglect of traditional foods. Breadfruit ( Artocarpus altilis and Artocarpus mariannensis) is the most widely available traditional starch food for RMI people. The ripe fruit flesh is yellow or sometimes orange, as with the Mejwaan cultivar, indicative of carotenoid content. Carotenoid-rich foods can protect against VAD and non-communicable diseases. Yet little information on carotenoid content of Marshallese breadfruit cultivars is available. This study documents traditional knowledge of breadfruit cultivars using ethnography, and analyzed 6 breadfruit cultivars of 2 species, A. altilis and A. mariannensis, for provitamin A (β- and α-carotene) and total carotenoid content, using high performance liquid chromatography (HPLC). The ripe seeded breadfruit Mejwaan contained strikingly rich concentrations of β-carotene (3540. μg/100. g fresh weight). Samples of other ripe and mature cultivars, characterized by lighter-colored flesh, contained medium- to low-carotenoid content (<5-102. μg/100. g fresh weight). As samples were harvested from field-grown plants, it should be noted that the quantity of carotenoids may vary when the same cultivars are planted in different sites. Local experts reported that Mejwaan was once common but is now becoming rare, and that people are now consuming its ripe flesh much less frequently; the discovery of Mejwaan's rich carotenoid content should be used to promote this cultivar for its important health benefits. © 2014 .
