Fruit form influences postprandial glycemic response in elderly and young adults

Abstract

Although fruit form influences GR in the elderly and young adults, all fruit types and forms studied were found to be low GI. This study indicates that fruits are a valuable source of nutrient irrespective of the form of delivery in elderly and young adults. This study was registered at www.anzctr.org.au as ACTRN12614000655640.

Southern Brazilian native fruit shows neurochemical, metabolic and behavioral benefits in an animal model of metabolic syndrome

“…PcRT extract was able to prevent some of the metabolic changes induced by HPD, such as weight gain and visceral fat accumulation, glucose intolerance, hyperglycemia, and dyslipidemia. In accordance, clinical and preclinical studies have shown a reduction of glycemic index and beneficial effects in lipid metabolism by guava, belonging to Psidium genus (Batista et al 2018;Tey et al 2017). It has been reported that increased TAG may cause reduction in peripheral insulin action (Khanal et al 2012).…”

Postprandial Glycemic and Insulinemic Effects of the Addition of Aqueous Extracts of Dried Corn Silk, Cumin Seed Powder or Tamarind Pulp, in Two Forms, Consumed with High Glycemic Index Rice

“…This suggests that the food matrix in which phytochemical-rich ingredients are consumed has an effect on postprandial metabolic responses. Our research group has previously shown that both postprandial glycemic [22] and lipidemic [45] responses depended on the food matrix. Others have also shown that the postprandial glycemic lowering potential of polyphenol-rich ingredients depended on the form in which it was consumed [46], and various cooking methods were shown to significantly alter polyphenol bioaccessibility as well as the biological properties of polyphenol-rich ingredients, including differences in α-glucosidase inhibitory activity [47].…”

“…For cumin and tamarind, we used dietary doses, whereas for corn silk we used two separate doses—the “high dose” consisting of an amount commonly used in traditional Chinese medicine, and a lower (one-half of the high) dose to assess whether this lower, “dietary” dose would still be effective in improving glycemic parameters. Moreover, there is now considerable evidence that the food form plays an important role in determining glycemic and/or insulinemic responses [21,22,23]. We therefore investigated all the test ingredients in two separate forms: (i) extracts consumed as a drink (D) with plain rice or (ii) extracts added into rice (R) during cooking and consumed with plain water.…”

The Impact of Nutrition-Based Interventions on Nutritional Status and Metabolic Health in Small Island Developing States: A Systematic Review and Narrative Synthesis

“…Twenty-four studies were conducted in the Caribbean: nine in Haiti [25][26][27][28][29][30][31][32][33], three in Cuba [34][35][36], three in Dominican Republic [37][38][39], three in Jamaica [24,40,41], three in Trinidad and Tobago [42][43][44], two in Puerto Rico [45,46] and one in Barbados [47]. Eighteen studies were conducted in the Atlantic, Indian Ocean, Mediterranean and South China Sea (AIMS region): fifteen in Singapore [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62], two in Mauritius [63,64] and one in Seychelles [65]. Eight studies were conducted in the Pacific region: two in Fiji [66,67], one in American Samoa [68], one in Tonga [69], one in French Polynesia …”

“…Of the fifty studies, twenty-eight used randomised designs: fifteen individuallyrandomised parallel group trials [40,41,[43][44][45][46][48][49][50][51]53,55,57,64,65], eight cluster-randomised parallel group trials [25,[29][30][31]33,61,68,72], and five individually-randomised cross over or other matched trials [24,46,52,58,64]. Twenty-two were of non-randomised study design: fifteen uncontrolled before and after studies [32,34,36,37,39,47,52,54,56,57,59,62,63,67,71], six controlled before and after studies [26,38,60,66,69,…”
