Benefits of dark chocolate intake on retinal vessels functionality: a randomized, blind, crossover clinical trial.

Analyzing the venous dilation percentage, there was an increasing trend after the dark chocolate intake (mean venous dilation of 3.265 ± 3.159% at the baseline vs 4.465 ± 2.969% after the dark chocolate intake, p = 0.086), and lower changes after the milk chocolate intake (p = 0.124) (Table 2 ).
