Improve your attention span with Black Tea

Black tea is now considered to improve people’s attention span after the European Food Safety Authority (EFSA) endorsed recent studies.

Unilever conducted three human intervention studies. Participants drank two to three servings of either black tea or tea-flavoured colored water on separate occasions.

Test subjects then undertook a series of tasks to measure their attention span both before and after each serving. Those drinking tea consistently showed higher attention scores which are based on accuracy and the speed of their responses. One study demonstrated that the stronger the tea, the higher the scores.

According to EFSA “the claimed effect depends on the concerted action of two substances, caffeine and l‐theanine. Both of which are present in black tea. In order to obtain the claimed effect, 2–3 servings of black tea providing at least 75 mg of caffeine in total should be consumed within 90 minutes.”

In a press release, Clive Gristwood, executive vice president of R&D Foods & Refreshment at Unilever, said the company is pleased to be one of the few companies to achieve EFSA’s official positive scientific opinion.

“We consider it a reward for our long years of extensive research in the benefits associated with drinking tea.”

The European Commission will now review the opinion. Unilever will have exclusivity to use this claim for five years, if the application is granted.

The EFSA endorsement is a first involving tea.
