The effects of cocoa flavanol supplementation on endothelial function and exercise performance.
Cocoa flavanols have gained attention from beneficial effects on endothelial function and exercise performance, especially in clinical populations. Few studies have utilized healthy college-aged adults. Twenty college-aged males and females completed this randomized, double-blind study. …

The Influence of Dietary Flavanol Mean Degrees of Polymerization on Sensory Preference Trends and the Metabolic Syndrome
… to combat illness. A relationship between flavanol consumption, health benefits, and taste perception has been well documented. Dietary flavanols are secondary plant metabolites that exist naturally in a wide array of polymerization states. The mechanisms behind the protective effects of …

Evaluation of cocoa (Theobroma cacao) bean processing strategies to enhance alpha-glucosidase inhibitory activity of dietary cocoa
… are a highly concentrated source of dietary flavanols- bioactive compounds associated with the health protective properties of cocoa. Cocoa beans undergo processing steps, such as fermentation, roasting, winnowing, grinding, pressing, etc., to produce a final product with specific desirable …

Gut Health Benefits of Natural and Alkali-Processed Cocoa (Theobroma cacao) with and without Inulin
… of combining cocoa and inulin. Polyphenolic and flavanol compounds in natural cocoa, alkalized cocoa, and inulin powders were characterized using Folin-Ciocalteu (total polyphenols) and 4-dimethylaminocinnamaldehyde (total flavanols) assays, thiolysis , and HILIC UPLC-MS/MS. Treatments of cocoa …

Grape powder attenuates the negative effects of GLP-1 receptor antagonism by exendin-3 (9-39) in a normoglycemic mouse model
… age 65+. Foods rich in polyphenols, including flavanols and other flavonoids, have been studied for their putative beneficial effects on many different health conditions including type 2 diabetes mellitus and prediabetes. Studies have shown that some flavanols increase glucagon-like peptide 1 …

Anti-Diabetic and Anti-Obesity Activities of Cocoa (Theobroma cacao) via Physiological Enzyme Inhibition
… cacao) decrease levels of polyphenolic flavanol compounds. However, it is largely unknown how these changes in polyphenol levels caused by processing affect cocoa's anti-diabetic and anti-obesity bioactivities, such as inhibition of certain enzymes in the body. Polyphenol profiles, …

Structure, Mechanism and Chemical Modulation of the Protein Kinase-nuclease Dual-enzyme IRE1
… active site to potentiate nuclease function. The flavanol quercetin was identified in a chemical screen as a potent stimulator of IRE1 nuclease output. To understand the mechanism of action of quercetin, I determined the crystal structure of IRE1cyto in complex with quercetin and ADP. Quercetin …

Phytochemical diversity and genetics of purple corn
… lines also resulted in the identification of new flavanol-anthocyanin condensed pigments not previously reported in maize. Further analysis of AR phytochemistry identified abundant apigenin-derived flavones that were found to copigment with anthocyanins, resulting in darker and bluer extracts and …

Characterization of anthocyanin production in maize germplasm
… Pericarp-pigmented accessions that could produce flavanol-anthocyanin dimers called “condensed forms” were the most important accessions in the survey in terms of total anthocyanin content. In the survey acylated anthocyanins were typically the most predominant pigments types, except in a few …

Discovery and dissemination of new knowledge in food science: Analytical methods for quantification of polyphenols and amino acids in fruits and the use of mobile phone-based instructional technology in food science education
… The DMAC method was the most specific to flavanols, and the BSA method was not suitable for quantification of smaller flavanols. Quantitative performance of these four methods was evaluated using a broad range of fruit-derived samples. Variation in quantitative results obtained using these …

The Effects of Acute Consumption and Chronic Supplementation of Cocoa on Overweight and Obese Adults at Risk of Developing Diabetes
… state to the clinically diagnosed diseases. Flavanols in cocoa powder have been shown to reduce blood glucose concentrations, improve insulin sensitivity, and decrease gut permeability in animals and humans, but it is unknown if this occurs in adults with prediabetes. Therefore, we first …

Effects of aspects of terroir on the phenolic composition of New Zealand Pinot noir wines
Phenolic content is an important dimension of Pinot noir wine quality. This study aimed to find generic relationships between the phenolic content of Pinot noir wines produced from well-defined locations (single vineyards) in New Zealand, as determined from various chemical analyses, and aspects of …
