Eating a bowl of blueberries for breakfast can stop you flagging in the afternoon.Researchers found that a large benefit of the fruit called by people as nature’s superfood- boosts memory and concentration up to 5 hours later.
In studies, volunteers who drank a blueberry smoothie in the morning performed much better mental tasks in the mid afternoon than people who had the other drink. Scientists who made the discovery think the antioxidants in blueberries stimulate the flow of blood and oxygen to the brain and so keep the mind fresh. The finding means people can use blueberries and other rich in anti-oxidant fruits to improve their abilities during exams or on long, difficult days at work. Dr who carried out the study said: After an hour there was a little difference in the attention tests. But after 5 hours people who did not drink the blueberry smoothie saw their performance fall by 14 to 21 per cent.
