Food & Function has revealed that cocoa is effective in relieving stress.
The function of cocoa in suppressing reduced cerebral blood flow under stress extends beyond mere mood improvement. Through a physiological approach that prevents peripheral vasodilatory dysfunction, it may contribute to "reducing needle-stick pain" and "improving first-time success rates."

abstract
Dietary choices during stressful periods often worsen, potentially impacting how stress affects vascular health. For instance, fat intake has been shown to inhibit the recovery of endothelial function after mental stress, whereas flavanols promote recovery. This study investigated whether flavanols, in combination with fat, could mitigate the negative effects of fat on stress-induced endothelial dysfunction in a randomized, counterbalanced, double-blind, crossover postprandial intervention. Twenty-three healthy young men and women consumed a high-fat meal (56.5 g fat) with either high-flavanol (150 mg (-)‐epicatechin) or low-flavanol (<6 mg (-)‐epicatechin) cocoa 1.5 hours prior to an 8-minute mental stress task. The primary outcome, brachial flow-mediated dilation (FMD), was assessed at baseline and 30 and 90 minutes post-stress. Prefrontal cortex oxygenation was assessed at rest and during stress postprandially. Forearm blood flow (FBF), blood pressure (BP), cardiovascular activity, common carotid artery (CCA) diameter, blood flow, and mood were assessed before, during, or after stress. FMD was reduced 30 and 90 minutes post-stress following low-flavanol cocoa. High-flavanol cocoa attenuated FMD impairment 30 minutes post-stress and improved FMD at 90 minutes. Mental stress similarly increased cortical oxygenation, FBF, BP, cardiovascular activity, and disrupted mood in both conditions. CCA diameter increased, but CCA retrograde flow decreased post-stress, with no difference between conditions. In summary, flavanols can suppress stress-induced impairments in endothelial function when fat is consumed under stress, but do not affect brain oxygenation. These findings may have significant implications for dietary choices rich in flavanols to protect vasculature from stress.
