Many people like to drink coffee, so is coffee a healthy drink?
If it is a healthy drink, can you drink more drinks? Today we will summarize the research on coffee and cardiovascular health, especially those who usually like to drink coffee friends, can you see if you drink it right?
First, coffee and cardiovascular and cerebrovascular diseases
Studies were published in the European Journal of Heart Disease Prevention
A follow-up study of 500,000 people was followed up for 11 years, and the incidence and mortality of cardiovascular disease were observed separately: people who did not drink coffee, drank coffee in moderation, and drank a lot of coffee.
The results found that compared with those who never drank coffee, if they insisted on drinking the right amount of coffee every day, the risk of death from cardiovascular disease was reduced by 17%; the risk of stroke was reduced by 21%,; and the risk of all-cause death was reduced by 12%.
This study tells us that the right amount of coffee is conducive to the prevention of cardiovascular and cerebrovascular diseases.
Second, coffee and arrhythmias
Some people will feel their heart beat faster after drinking coffee, of course, this part of the people do not recommend that you drink coffee for a long time.
Some people will think that drinking coffee will cause the heart to beat faster, will it cause arrhythmias such as atrial fibrillation? In fact, for people who have no discomfort after drinking coffee, long-term moderate amount of coffee is not only harmless, but may also be conducive to the prevention of arrhythmias.
A study published in jama's sub-journal of internal medicine, which followed more than 386,000 adults for 4.5 years, found that people who drank the right amount of coffee every day were more than those who never drank coffee. The risk of developing arrhythmias is reduced by 3%, the risk of atrial fibrillation and/or atrial flutter is reduced by 3%, and the risk of supraventricular tachycardia is reduced by 4%.
Therefore, people who usually have the habit of drinking coffee can continue to maintain this habit, because drinking the right amount of coffee will not increase the risk of arrhythmias.
Third, it should not be too much
Even if oxygen and water are necessary for us human beings, we should not be too much, otherwise we will be poisoned by oxygen and water. So of course, drinking coffee should not be too much.
Australian researchers have observed 400,000 people and found that the more coffee they drank, the more the total brain volume and the volume of gray matter, white matter, and hippocampus were reduced. If you drink more than 6 cups of coffee a day, the brain is prone to atrophy and the risk of dementia is significantly increased.
At the same time, these studies found that the risk of dementia increased compared to those who drank 3 cups of coffee a day, never drank coffee or drank more than 6 cups of coffee a day.
So, even if you like to drink coffee, you should not drink too much.
Fourth, the effect of freshly ground coffee and instant coffee is not the same
Instant coffee is a mixture of creamer, sugar, and coffee, with a lot of sugar and fat, and studies have found that people who are accustomed to drinking instant coffee have a 152% higher risk of breast cancer.
People who drink freshly ground coffee for a long time have the opposite result, with a 52% lower risk of breast cancer.
According to the European Journal of Cardiology Prevention, people who drank small to moderate amounts of freshly ground coffee every day had a 25% lower risk of cardiovascular death; however, people who drank instant coffee regularly did not have a reduced risk of all-cause death and cardiovascular death.
So, if you like to drink coffee, it is still recommended to make coffee at home.
5. Guideline Recommendations
Combined with the "Guidelines for the Prevention of Cardiovascular Diseases in China", the following suggestions are given to you:
1, drink coffee to about 2 cups a day is appropriate, should not be too much, it is best to freshly ground coffee.
2. It is not recommended to drink coffee when eating, so as not to affect the absorption of calcium, iron and vitamin B6 in food.
3. It is not recommended for pregnant women and children to drink coffee.
4, instant coffee added ingredients, such as cream, sugar, coffee companion, etc., should not be too much, so as not to be detrimental to health.
In short, the right amount of coffee is good for health, but you should drink it, not too much!
