"Dad, drink less strong tea, it's not good for your health." Uncle Li's son saw it in his eyes and was anxious in his heart.
Uncle Li always waved his hand and said with a smile: "You don't understand, I can't do without this cup of tea in my life." ”
Not long ago, he often felt dizzy and chest tightness, but he thought it was because he was old and didn't pay much attention to it. Until one day, he suddenly fainted on the balcony and was rushed to the hospital.
After examination, the doctor diagnosed Uncle Li as having a cerebral infarction, and solemnly told him not to touch the strong tea again in the future.
1. Drink two cups of black tea a day to live longer?
In August 2022, a study published in the Annals of Internal Medicine pointed out that tea drinking was associated with a reduced risk of death among groups with black tea as the main consumption type, especially those who drank two or more cups of black tea per day, and the risk of death was the lowest.
The study surveyed about 500,000 men and women between the ages of 40 and 69, and of those participants, 85 percent had a tea drinking habit, and 89 percent said they drank black tea.
People who drank more than two cups of black tea per day had a 13% lower risk of all-cause mortality compared to those who did not drink tea.
Studies have also found that drinking tea helps reduce mortality from cardiovascular disease, ischemic heart disease, and stroke.
Scientific studies have proven that drinking black tea does provide health gains, but the benefits go far beyond that.
1. It is beneficial to lower blood pressure
Studies have shown that drinking black tea reduces the risk of high blood pressure by 26%. In addition, a team led by Professor Jonathan Hodgson of the University of Western Australia analysed tea drinking data from 95 people between the ages of 35 and 75 and found that black tea had a lower systolic and diastolic blood pressure.
2. Reduce the risk of diabetes
At the 2022 annual meeting of the European Association for the Study of Diabetes (EASD), research published in Stockholm, Sweden, revealed the link between tea consumption and a reduced risk of type 2 diabetes: drinking a cup of tea a day reduces the risk of type 2 diabetes by about 1%. The study covered black, green, and oolong teas.
2. People who love tea are more likely to suffer from Alzheimer's disease?
As a long-standing cultural custom, tea drinking has long been deeply rooted in the hearts of the people. However, a study from Sun Yat-sen University has broken our cognition: is tea drinking actually related to Alzheimer's disease?
A research paper published in the journal "Frontiers in Nutrition" by researchers from the Seventh Affiliated Hospital of Sun Yat-sen University. The study showed that drinking 5-6 cups of tea per day was associated with a lower risk of Alzheimer's disease, while drinking too much was associated with a higher risk of AD. Drinking an extra cup of tea a day is associated with a 48% increase in the risk of AD. When drinking more than 13 cups of tea, the risk of AD increased by 67%.
The researchers also found that drinking too much tea per day was closely related to a decrease in gray matter volume and right hippocampus volume.
A study by Yu Jintai's team at Huashan Hospital affiliated to Fudan University also concluded that there was a U-shaped association between tea consumption and the risk of dementia, and that when the amount of tea consumed was more than 6 cups/day, there was no difference between the risk of dementia in those who did not drink tea.
Everything needs to be done in moderation, although tea is everyone's favorite healthy drink, but once it is excessive, it will make Alzheimer's come to the door earlier.
