Drinking too much coffee reduces brain capacity and increases the risk of dementia? The influence of getting smarter by drinking coffee
Shortly before 9 o'clock this morning, the Ministry of Science and Technology website published an article that drinking too much coffee reduces brain capacity and increases the risk of dementia.

Later, "drinking too much coffee reduces the capacity of the brain" on Weibo's most searched list. However, the website of the Ministry of Science and Technology deleted the article on the same day.


Coffee is one of the most popular beverages in the world, and it has attracted many scientists to study its composition and function. Some of them reduce the risk of Parkinson's disease, type 2 diabetes, gallstones, arrhythmias and several cancers.
As early as July 23 this year, a report in the US The Hill newspaper said that a new study by the University of South Australia showed that drinking too much coffee makes the brain smaller and is associated with a 53% increase in the risk of dementia.
Researchers at the University of South Australia published a research paper entitled High coffee consumption, brain volume and risk of dementia and stroke in the journal nutritional Neuroscience (Nutritional Neuroscience).

The researchers conducted a prospective analysis of habitual coffee consumption among 398646 UK Biobank participants aged between 37 and 73, of whom 17702 had magnetic resonance imaging (MRI) data. Through the parameter estimation of the related model, the probability of the effect of coffee on the brain was estimated.
When comparing how often the subjects drank coffee a day, the researchers found that people who drank more than six cups of coffee a day had a relatively small brain capacity and a 53% increased risk of dementia compared to those who drank only two cups of coffee a day.

Dementia is a degenerative brain disease that affects memory, thinking, behavior and the ability to perform daily tasks. Stroke is a condition in which the blood supply to the brain is interrupted, which can lead to hypoxia, brain damage, loss of function and even death.
The study is similar to a study by the University of Basel in February that caffeine changes the structure of the brain associated with memory and has only a temporary effect on gray matter.

However, to put aside the dose and talk about toxicity is to play hooligans! For example, drinking clean water can also be poisoned, how is it poisoned? Drink too much in a short time, water poisoning!
The same goes for coffee! Once there is such negative news, someone is clamoring about not drinking coffee. Quit! According to the example of water mentioned earlier, do these people stop drinking water from now on?

"when there is a limit to everything, enough is enough." this is not just a statement. Although the coffee is delicious, it also has a certain amount! It is not difficult to find many studies on the health benefits of coffee, which do not exceed that standard (FDA recommends no more than 400mg of caffeine a day for healthy adults).
For example, an article shows that drinking three to five cups of coffee a day in middle age is associated with a 65% reduction in the risk of dementia in old age.

Therefore, there is no need to panic. If you really want to calculate whether you have too much caffeine every day, you can calculate it according to the following formula:

Of course, the 400mg given by FDA can only be regarded as the ceiling, and you also need to make adjustments according to your own situation without piercing the ceiling.
