New Research Shows Dried Plums Influence Satiety and Improve Dietary Quality for Women
(April 30, 2009) - Sacramento, Calif. - Consuming dried plums as a snack may help suppress appetite relative to a popular low-fat snack while offering nutritional benefits, according to recent research presented at the 2009 Experimental Biology meeting in New Orleans.
"We felt it would be valuable for weight control to identify satiating snack foods, since about 87 percent of women snack twice daily," said lead researcher Mark Kern, PhD, Department of Exercise and Nutritional Sciences at San Diego State University. "Our research suggests that dried plums may help curb appetite more than a similarly sweet, low-fat cookie snack, perhaps by lowering glucose or appetite-regulating hormones."
Nineteen adult women, who had previously fasted, consumed two 238-calorie snacks (dried plums or low-fat cookies), 238-calorie white bread, or water on separate days two hours prior to being presented with a meal to be consumed until satisfied. Participants completed hunger-related questionnaires, and researchers analyzed their blood at regular intervals. Satiety appeared to be higher for the dried plums versus low-fat cookies. Dried plums also appeared to elicit lower levels of plasma glucose and insulin than the low-fat cookie.
Kern also studied the influence of 100-calorie servings of snacks of dried plums versus low-fat cookies twice daily for two weeks on total energy, essential micronutrient, fiber and fat intake, and effects on serum triglycerides and bowel habits in 26 adult women. 2 The research team discovered that consistent consumption of dried plums appeared to improve blood lipids and diet quality and ease bowel movements in comparison to a commercially processed snack.
"Since appropriate snacking is likely important for optimal weight management practices, we were pleased that our research demonstrated the satiating affect of a dried plum snack and its promotion of improved dietary intake and good digestive health," said Kern.
Additional research from Florida State University and Oklahoma State University, also presented at the Experimental Biology meeting highlighted the positive role that dried plums may help play in bone health and metabolism, in immune response and in reduction of markers of inflammation. 3,4,5
These studies taken together add further evidence that dried plums are a Super Fruit, not only for digestive health, but for other important areas of health as well. These studies were supported or sponsored by the California Dried Plum Board (CDPB).
