The application of soluble supports in the radiochemical asymmetric total synthesis of tea flavanols.
Flavan-3-ols such as (—)-epicatechin and (+)-catechin are found in significant concentrations in red wine, green and black teas and cocoa. The radiolabelling of flavan-3-ols for feeding studies would require a short high-yielding route from the point of introduction of the label. …

Oligomeric cocoa procyanidins possess enhanced bioactivity compared to monomeric and polymeric cocoa procyanidins for preventing the development of obesity, insulin resistance, and impaired glucose tolerance during high-fat feeding
Flavanols are polyphenols that are known to have many beneficial effects on the body. Cocoa is a major source of these flavanols. However, research on the potential anti-obesity and anti-diabetic health benefits of cocoa flavanols is lacking in the literature. Furthermore, the effect that the size …

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
… 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 flavanols are not entirely understood, particularly when considering how the mean degrees of …

The effects of polyphenol rich chocolate on cardiovascular risk and glycaemic control in type 2 diabetes mellitus
… in vitro and in vivo studies suggest that plant flavanols may have beneficial effects for people with diabetes, including potentially those found in cocoa and chocolate. Cesar Fraga suggested in 2005 that perhaps we should eat more chocolate to prevent and manage diabetes, following a study 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 …

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 …

Colonic metabolism of dietary grape seed extract: Analytical method development, effect on tight-junction proteins, tissue accumulation, and pan-colonic pharmacokinetics
… chronic supplementation of the diet with flavanols did not increase colonic tissue accumulation of PCs or their microbial metabolites over a 12 week feeding study. This was the first long-term study of its kind, and the results indicate that we still do not fully understand the outcome of …

Gut Health Benefits of Natural and Alkali-Processed Cocoa (Theobroma cacao) with and without Inulin
… and 4-dimethylaminocinnamaldehyde (total flavanols) assays, thiolysis , and HILIC UPLC-MS/MS. Treatments of cocoa and inulin were made in 1:2 cocoa:inulin and 1:4 cocoa:inulin mixtures for both natural and alkalized cocoas. Cocoa mixtures, in addition to both cocoa powders and inulin …

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 …

Flavonoid Intake and Prostate Cancer Aggressiveness In African Americans and European Americans
… increasing intakes were found for flavonols and flavanols, although these odds ratios did not reach statistical significance. Associations between flavonoids and aggressiveness were modified by smoking status and age, such that inverse associations were strongest in men younger than age 65 and in …

Anti-Diabetic and Anti-Obesity Activities of Cocoa (Theobroma cacao) via Physiological Enzyme Inhibition
… decreases (p<0.05) in total polyphenols, flavanols, and anthocyanins between the two sets of unfermented and fermented cocoa extracts (CEs). All CEs effectively inhibited α-glucosidase (lowest IC50 = 90.0 ug/mL for UL) and moderately inhibited α-amylase (lowest IC50=183 ug/mL for FL), …

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 …
