What happened to those who drank both coffee and tea?

If you choose the three major drinks that contemporary people cannot do without, then cola, milk tea, coffee, and tea are estimated to be among the best.

Coke and milk tea belly, in addition to bringing happiness, may also bring obesity, cardiovascular problems.

So, what happens when coffee and tea are drunk?

Drink only coffee

Many workers' days begin with the aroma of coffee.

As if the liquid refreshes the brain, a cup of coffee is down, and the state is doubled.

Of course, in addition to bringing excellent work efficiency, coffee will also bring a series of effects to the body.

What happened to those who drank both coffee and tea?

Coffee contains a large number of bioactive ingredients, such as chlorogenic acid, caffeine, fenugreek line, etc., which have antibacterial, anti-inflammatory, antioxidant and other effects [1].

Scholars from Tianjin Medical University found a J-type association between "drinking only coffee" and all-cause mortality, cardiovascular and respiratory mortality, and an anti-J-type association with digestive disease mortality.

Specifically, when drinking less than 1~2 cups of coffee per day, the observed mortality rates from all-cause, cardiovascular and respiratory diseases were the lowest [2].

In the face of this gratifying result, I have to sigh that I drink coffee in moderation every day, and work healthily for fifty years~

Drink only tea

In addition to coffee, tea is also a daily necessity for many people.

As the origin of tea culture, China likes to drink tea for many people. Not only quenching thirst, drinking tea also has a unique Chinese aesthetic fun.

In addition, the amino acids, tea polyphenols, caffeine and other substances contained in tea are also beneficial to health [3].

Regarding tea drinking, scholars have also found an anti-J-type association between "drinking tea only" and all-cause, cardiovascular and digestive disease mortality, and a J-type association with respiratory disease mortality.

Specifically, the risk of all-cause death was lowest when 3 cups of tea per day were drunk; Drinking 6 cups of tea per day can minimize the risk of death from digestive diseases [2].

Drink both coffee and tea

Seeing this, some friends will ask, since drinking tea and coffee have so many health benefits, what will it be like to drink the two together?

The researchers also took this into account and analyzed the combination of coffee and tea, and found that there was a significant correlation between coffee and tea consumption and all-cause mortality.

After all, coffee and tea contain bioactive components such as caffeine and chlorogenic acid, which are important antioxidants that play a vital role in anti-inflammatory, blood pressure, insulin resistance, and improving endothelial function [2].

Specifically, the study found that:

1. For people who do not drink much coffee, increasing tea consumption will also increase all-cause mortality; For people who drink more coffee, the relationship is U-shaped.

2. For tea drinkers, no matter how much or how little they drink, the relationship between increasing coffee consumption and drinking all-cause mortality is U-shaped.

This also means that for people who drink tea and drink more coffee every day, appropriately increasing the consumption of another beverage has the effect of reducing the risk of all-cause death.

So, how much exactly to drink?

Based on the sample data, the researchers came to the conclusion that:

Compared with people who do not drink coffee and tea, drinking 1~2 cups of coffee and 2~4 cups of tea per day has a 22% lower risk of all-cause mortality, a 24% lower risk of cardiovascular disease death, and a 31% lower risk of respiratory disease death [2]!

I have to say that coffee and tea are worthy of being the "life water" of workers, not only making office life less monotonous, but also adding strength to health. Is your "life water" coffee or tea?
