Antidiabetic dietary materials and animal models
2016
Wang, Sunan | Zhu, Fan
The ever-increasing occurrence of diabetes worldwide demands cost-effective anti-diabetic strategies. Food-based materials have great potential as efficient anti-diabetic agents. Focusing on the literatures of the recent 5years, this review summarizes the methods, findings, and limitations of each research involving non-medicinal foods (individual and mixed) and diabetic animal models. Various types of fruits, vegetables, legumes, cereals, spices, beverages, oilseeds, and edible oils showed antidiabetic effects in different animal models. Animal feeding trials rarely had identical designs in food doses, feeding schedules, and routes of administration, as well as biochemical markers for antidiabetic evaluation. Various possible cellular and metabolic targets were speculated for the anti-hyperglycemic effects of the dietary materials, and the molecular mechanisms of action remain to be better explored. Short-term (maximum 16weeks) antidiabetic studies have been established. Limited safety/tolerability data are available for antidiabetic dietary materials. Findings from current animal studies present a generic antidiabetic dietary pattern associated with plant-based whole foods, which agrees well with the findings of epidemiological studies.
