For thousand of years and from many ancient Chinese traditional medicine related articles or books, tea is known for its benefits to health and many are confirmed by various Western medical researches around the world today. But still there are some concerns whether regularly drinking tea is good or bad for kidneys.
Before we further explore whether regularly drinking tea is good or bad for kidnies, let’s first establish a basic understanding about how to sustain and maintain a healthy life style by referring to a very well saying old idiom in Dutch – Too is too much (Te is te veel); or knief cuts at two sides (een mes snijd aan twee kanten), which is very similar to Chinese old idioms, for example extreme happiness hindens the growth of sadness and a knief has two sharp edges that cuts at both sides (刀有雙刃).
- Tea contains unique antioxidants, i.e. flavonoids and ECGC that have been confirmed are helpful to against free radicals that contribute to cancer, heart disease and clogged arteries.
- Different kind of tea has its unique compounds; even though tea also contains caffeine but it’s much less than in coffee and it helps to improve the brain function and blood circulation.
- The different process of tea leaves influence the explanation fusible of caffeine and polyphenol content include flavonoids by the process.For example, even though high fermented Oolong tea and black tea probably have lower concentrations of polyphenols than green tea, but the complex processes and fermentation actually stimulate the antioxidation power. Here is a brief summary of health benefits in tea according to WebMD:
Green tea:it has a high concentration of EGCG and its antioxidants may interfere with the growth of bladder, breat, lung, stomach, pancreatic, and colorectal cancers; prevent clogging of the arteries, burn fat, counteract oxidative stress on the brain, reduce risk of neurological disorders like Alzheimer’s and Parkinson’s diseases, reduce risk of stroke, and improve cholesterol levels.
White tea: according to research, white tea has the most potent anticancer properties compared to more processed teas.
Oolong tea: From research, it shows the antioxidants from oolong tea have lower bad cholesterol levels.
Black tea: Different process and quality can influence the caffeine content, for example in the first few seconds more caffeine would melt from tea bag and instant tea. Recent various studies have also shown that black tea may protect lungs from damage caused by exposure to cigarette smoke. It also may reduce the risk of stroke.
Pu-erh tea: Made from fermented and aged leaves. Considered a black tea, its leaves are pressed into cakes. One animal study showed that animals given pu-erh had less weight gain and reduced LDL cholesterol.
Tea is not the problem, it is People
So back to the question “Is regularly drinking tea good or bad for kidneys”, I can once again to repeat the reminder:
- It depends on what of tea you choose to drink, i.e. whole leaf vs. BOP or vs. CDC or vs. instant tea; pure authentic quality vs. aromatic tea
- It depends on how you brew your tea, i.e. how strong you brew your tea It depends on when you drink what
- It dpends on how much do you drink in a day and when – how much do you know and respect your physical conditions and needs
