Eur J Nutr . 2021 Sep; 61(2):687-701. PMID: 34505919
Purpose: Impaired glucose tolerance (IGT) is a pathophysiological condition characterized by insulin resistance with known metabolic consequences such as postprandial hyperglycemia and hypertriglyceridemia. We hypothesized that fortifying a meal with...

Nutrients . 2019 Feb; 11(2). PMID: 30781485
Randomized controlled trials indicate that flavanol-rich cocoa intake may improve postprandial glucose and lipid metabolism in patients with type 2 diabetes (T2D), based on studies with meals that impose a...

Dicks L, Kirch N, Gronwald D, Wernken K, Zimmermann B, Helfrich H, et al.
Nutrients . 2018 Oct; 10(10). PMID: 30301127
Regular cocoa consumption has been shown to improve blood pressure (BP), insulin sensitivity, and lipid levels in patients with type 2 diabetes (T2D), using up to 100 g of chocolate...

Kirch N, Berk L, Liegl Y, Adelsbach M, Zimmermann B, Stehle P, et al.
Am J Clin Nutr . 2018 Jun; 107(6):948-956. PMID: 29868915
Background: Regular cocoa consumption has been shown to reduce blood pressure, improve lipid profiles, and increase insulin sensitivity and flow-mediated dilatation in healthy adults. It is assumed that these effects...

Wolf E, Utech M, Stehle P, Busing M, Helfrich H, Stoffel-Wagner B, et al.
Obes Surg . 2015 Dec; 26(8):1821-9. PMID: 26704923
Background: Osteomalacia and cardiometabolic disorders are favored in morbidly obese patients due to an inadequate vitamin D (VD) status. Former trials supplementing orally VD (20-50 μg/day) in crystalline form after...

Am J Clin Nutr . 2012 May; 95(6):1365-77. PMID: 22552030
Background: Four meta-analyses of randomized controlled trials (RCTs) based on the classical random-effects model showed that cocoa consumption can reduce systolic blood pressure (SBP) and diastolic blood pressure (DBP). Because...

Phytopathology . 2009 Jul; 99(8):974-84. PMID: 19594317
Plant diseases are dynamic systems that progress or regress in spatial and temporal dimensions. Site-specific or temporally optimized disease control requires profound knowledge about the development of each stressor. The...
