Tb122: Comparison Of Alpha- And Beta-Carotene Content Of Supermarket Vs Roadside Stand Produce In Maine, R. J. Bushway, A, Yang, A. M. Yamani
Technical Bulletins
A study was conducted to determine the alpha- and beta-carotene content of supermarket vs roadside stand produce using high-performance liquid chromatography (HPLC). The fruits and vegetables were obtained from a major local supermarket chain and three roadside stands in Dixmont, Etna and Charleston, ME. Thirteen vegetables and one fruit were sampled during a ten-week period between July and September of 1985. Significant differences at the 0.05 level were observed between supermarket and roadside stand produce for only Swiss chard and green peppers with roadside stands having higher beta-carotene levels in both instances. Alpha-carotene was shown to be nonsignificant among sources …

Tb120: Alternative Assessment Of Individual Dietary Intake--A Pilot Study, Paula A. Quatromoni, Richard A. Cook
Technical Bulletins
In an initial effort to devise a rapid assessment alternative that would provide a reliable estimate of an individual's usual dietary pattern, a Predicted Food List (estimated, abbreviated food frequency), an Actual Food List (recorded, truncated food frequency), and a Typical Diet Day (foods perceived as commonly consumed in a 24-hour period) were compared with a 75-day food record. Overall, the Predicted Food List appeared to be the best tool for depicting an individual's usual food intake. It was concluded that a shortened list of food items characterizing an individual's normal nutrient intake level may be a useful instrument allowing …
