Randomized Controlled Trial Comparative Study Clinical Trial
Effect of cocoa and green tea on biomarkers of glucose regulation, oxidative stress, inflammation and hemostasis in obese adults at risk for insulin resistance.
Flavanols may provide protection against insulin resistance, but little is known about the amounts and types of flavanols that may be efficacious. ⋯ Short-term intake of cocoa and green tea flavanols does not appear to improve glucose metabolism; they do affect selected markers of one or more measures of oxidative stress, inflammation or hemostasis in obese adults at risk for insulin resistance.
