Article Abstract
The aim of the current study was to characterize the anthocyanin content and composition of a purple potato landrace cultivar (Solanum tuberosum 'Synkeä Sakari') and to compare the postprandial effects of purple-fleshed potatoes, yellow-fleshed potatoes and bilberries in potato starch on postprandial glycemia and insulinemia in healthy males. The purple potato meal caused smaller insulinemia than the yellow potato meal (iAUC 120 min 1347 and 2226, respectively, p = 0.012 and iAUC 240 min 1448 and 2403, p = 0.007) or the bilberry meal (iAUC 120 min 1920, p = 0.027). The purple potato meal caused a smaller plasma glucose at 40 min postprandially compared with the yellow potato meal (p = 0.044). The results of this study suggest that anthocyanin-containing purple-fleshed potatoes influence the postprandial insulinemia positively. Since potatoes are the world's largest non-grain commodity, replacing yellow-fleshed potatoes with purple-fleshed potatoes as staple food could have large potential in maintaining public health.
The objectives of this experiment were to determine the digestible indispensable amino acid score (DIAAS) for eggs cooked in different forms and in traditional egg-bread or egg-hash brown combinations, and to test the hypothesis that DIAAS in eggs is greater than in breads or potatoes. Nine ileal cannulated gilts (average initial body weight: 51.1 ± 6.
The Solanaceae plant family (), such as capsicum, eggplant, potato, and tomato, is made up of common plants consumed by humans. Despite having medicinal benefits, these plants can produce toxic alkaloid compounds. We report 2 cases of uncommon poisoning after consuming the berries as a meal.
Background: Circadian eating patterns and chrono-nutrition may influence obesity and disease incidence. Thus, this study aimed to assess the mediating role of obesity in the relationship between meal-specific dietary patterns (DPs), chrono-nutritional components, and cardiometabolic risk using structural equation modeling (SEM).
Methods: A cross-sectional study involving 825 Iranian adults was conducted.
Research Department of Child Nutrition, University Hospital of Pediatrics and Adolescent Medicine, St. Josef-Hospital, Ruhr-University, Bochum, Germany.
The study focuses on improving the dietary guidelines for children and adolescents in Germany by applying the Planetary Health Diet Index (PHDI) to the Optimized Mixed Diet (OMD).
The original OMD scored 68.24 points on the PHDI, highlighting strengths in fruits, vegetables, and fish while lacking in tubers, dairy, and red meat.
After modifying the diet to include more nuts, legumes, and whole grains, the PHDI score improved to 81.51 points, indicating a significant increase in sustainability and nutrient density.
This study examined the effects of various heat treatments on physicochemical properties, functionality, and starch digestibility of sweet potato flour. Heat treatments darkened the color but did not change the chemical structure. Solubility decreased and swelling power increased (17.
