Therefore, when you find that your memory is getting worse and worse, you always can't remember what you did a few days ago, or you tend to "forget what you want to do". In addition to the development of your brain nerves, you may actually have to check whether there is anything wrong with what you usually eat, or whether your eating habits are too bad.
In a study, UCLA found that eating midnight snack does lead to memory loss.
Eating midnight snack at night may cause amnesia! Dr Dawn Loh, from the Laboratory of Circadian Rhythm and Sleep Medicine at UCLA, said, "We proved for the first time that eating at the wrong time every day does have a profound impact on learning and memory. 」
Many people used to know that eating before going to bed or late at night is usually unhealthy, which will make people sleep badly, get fat easily, easily lead to diabetes, or gastroesophageal reflux; Gastroesophageal reflux can lead to indigestion, gastric ulcer, cough, asthma or dysphagia, and even lead to cancer. "Eating at night is not good. It is best not to eat after 8 pm, or sleep for at least three hours after meals. 」
In addition to physical problems, the research team also found that eating midnight snack can damage the memory center of the brain, especially the hippocampus responsible for short-term memory.
In mammals, the center of physiological clock is located in the front of hypothalamus and above optic chiasma, so it is called suprachiasmatic nucleus (SCN). It will accept light, temperature, humidity and diet to adjust the human 24-hour circadian rhythm. But in addition to this main physiological clock, most organs such as heart and pancreas also have their own physiological clocks, which can adjust the operation of organs.
Therefore, in addition to light, the time of eating will also affect people's overall biological clock. If you eat at bedtime, your memory will be damaged; But if you eat at a regular time, you won't have this problem.
The research team divided the mice into two groups, one group was fed at normal time, and the other group was fed at night. The mice quickly adapted to the feeding time, and there was not much difference in sleep time and food intake between the two groups. Rats that are always fed at night sleep more during the day, so it can be said that they have formed the habit of "catching up on sleep", but they all sleep intermittently.
However, when monitoring the physical changes of mice, it was found that the physiological clock affected by the suprachiasmatic nucleus of mice had little change, but the clock in hippocampus had completely moved. "Those maladjusted animals show serious defects in recalling their training. The research team said that the consolidation of memory is a transformation process after learning new things, and it will become a long-term memory, which requires a fixed sleep to form.
Don't eat after 8 pm! The research team said that eating at the "wrong" time will cause the clocks of the brain and the body to be inconsistent. Eating a midnight snack occasionally may not cause obvious harm; However, if you eat dinner at 1 1 every night, or wake up at 2 am to eat snacks, the risk of memory loss may increase.
"After eating, you should give your body at least three hours to digest, so that you can sleep well. If you are full, or have a late dinner and wake up hungry in the middle of the night, you'd better restrain yourself, or find a professional to help you change your schedule. The research team said, "You will be rewarded for improving your health and brain power. 」
