According to the research of a Japanese university, what we drink in the morning actually affects our work efficiency to a great extent! Fruit juice, as breakfast, generally has a high evaluation of self-work performance. Xinglin University in Japan conducted a study on 200 office workers aged 20-50 to explore the relationship between breakfast drinks and work performance. Based on the speed and accuracy of work. In the self-awareness survey of these respondents, 65% of those who have the habit of drinking juice think they are efficient people, while only 4 1% of those who have no habit of drinking juice, a difference of 24%. As for the accuracy of the work, 5 1% of people who are used to drinking juice think it meets the requirements, while only 33% of people who are not used to drinking juice have a difference of 13%. In terms of work concentration, 54% of people who are used to drinking juice think that their concentration is very good, while only 30% of people who are not used to drinking juice. When we actually discuss the time, we can also see the gap. People who drink juice can keep their concentration for an average of 4.8 hours, while people who don't drink juice can keep their concentration for an average of 4.3 hours. Koga Ryuhiko, MD, honorary professor of Japanese Xinglin University, conducted an experiment on drinking orange juice to activate brain function and change mental state, and studied the effects of orange juice on psychology and brain function. Six adult males and five male and female middle school students were given 100% orange juice and the changes were observed. The results show that compared with drinking boiled water, people will feel more positive after drinking orange juice, and most of the eight items, such as relaxation, pleasure, spirit and good mood, have been greatly improved after drinking orange juice, for example, the overall emotional state has increased by 2 times and the vitality has increased by nearly 2 times. But after drinking orange juice, the blood flow in the prefrontal lobe 16 area of the brain was observed. Compared with drinking boiled water, it was found that the blood flow in 14 region increased after drinking orange juice, which could activate brain function. Professor Koga said that the observation part is related to attention, memory and planning ability, and the blood flow in this part is increased and activated, which also contributes to the performance of work.

It can be made according to the ratio of 6: 4 of fruits and vegetables. The greener the choice of vegetables, the better, such as spinach or Komatsu, so that people can supplement chlorophyll to purify their blood. Green vegetables are good for satiety and help to excrete toxins from the body.
