Does dark chocolate really cheer us up?

Stevens and his colleagues conducted the study with 122 participants between the ages of 18 and 25.The researchers examined the levels of EEG and the effects of blood pressure after consuming a cocoa candy from 60 % compared to five control conditions.

The results for participants who consumed chocolate with 60% cocoa showed that the brain was more alert and attentive after consumption.His blood pressure also increased for a short time.

The most interesting results came n of one of the control conditions, with the introduction of a chocolate with 60% cocoa that included L-theanine, an amino acid found in green tea that acts as a relaxant.This combination has not been introduced in the market, but the researchers observed very interesting data.

«L-theanine is a really fascinating product that lowers blood pressure and produces what we call alpha waves in the brain, which make us calm and peaceful »- Stevens said.« We think that if chocolate raises blood pressure sharply, and L-theanine lowers blood pressure, then perhaps L-theanine could counteract the effects short-term hypertensive chocolate.»

In the participants who consumed the chocolate content with L-theanine, the researchers recorded an immediate drop in blood pressure.This finding could make it possible to market a chocolate that hypertensive people could take without risk to their heart.

Stevens hopes that the results of this study will encourage manufacturers to investigate further and consider the benefits of developing a chocolate bar made with high in cocoa and L-theanine.
