Health benefits of fresh tea
Fresh tea is a drink that many people love. Thanh Nien newspaper quoted specialist doctor Huynh Tan Vu, lecturer of Traditional Medicine Department, University of Medicine and Pharmacy, Ho Chi Minh City, as saying that green tea leaves are a popular food and drink in many cultures, bringing a number of important health benefits, such as protecting the health of our brain, heart and bones as well as beautifying the skin.
Below are the specific health benefits of fresh tea:
May reduce arthritis
If you want to reduce inflammation, add fresh tea leaves to your shopping list. In a mouse study, mice with rheumatoid arthritis (RA) that were given fresh tea leaf extract developed less severe symptoms than mice with RA who drank plain water.
Although more human studies are needed, scientists note that fresh green tea extract may be helpful when used alongside conventional RA treatments.
May lower blood sugar levels
People with type 2 diabetes have high blood sugar (hyperglycemia) due to insulin resistance, in which cells, muscles, and liver cannot effectively absorb glucose to provide energy for the body.
Is it okay to drink fresh tea left overnight is a concern of many people.
According to the American Diabetes Association, poorly controlled diabetes can increase the risk of complications such as heart disease, nerve damage, amputations and eye problems.
One study found that participants who consumed 150 ml of fresh green tea, three times a day, for four weeks, were able to reduce insulin resistance. Therefore, fresh green tea can be part of a healthy diet for type 2 diabetics.
Fights certain types of cancer
Cancer occurs when free radicals attack healthy cells in the body. Foods and drinks rich in antioxidants such as fresh tea are believed to help prevent this process, especially the EGCG content found in fresh tea leaves.
Can fresh tea left overnight be drunk?
Many people often have the habit of making a lot of fresh tea, if they don't drink it all, they save it for the next day. So, can fresh tea left overnight be drunk?
According to the Health & Life newspaper, Dr. Le Thi Huong, after 8 hours of tea being left, the harmful ingredients in the tea will increase, especially in hot weather, high temperatures, bacteria can easily grow, drinking it is harmful to health. Therefore, people should not drink tea left overnight.
Notes when drinking fresh tea
In addition to not drinking tea left overnight, Dr. Huong also recommends that you pay attention to the following if you drink fresh tea every day:
The concentration of tea must be appropriate.
If you brew too little tea, it will be bland and tasteless, but you should not regularly drink tea that is too strong, as it is harmful to your health.
Strong tea contains too much caffeine. Regularly drinking strong tea will increase blood triglyceride levels, causing atherosclerosis and heart pain.
Some acids in strong tea will cause protein and vitamin precipitation, hinder gastric juice secretion, stimulate the stomach and intestinal mucosa, causing imbalance in stomach and intestinal function, causing poor digestion, constipation, not beneficial for people with weak stomach and intestinal function.
In addition, some acids in tea can combine with some substances in food to form insoluble deposits, affecting the body's absorption of iron, which can cause iron deficiency anemia in the long term.
Do not drink tea after drinking alcohol.
After drinking alcohol, the heart beats faster, causing mental excitement, and tea has the effect of stimulating the central nervous system. If you drink tea after drinking alcohol, it is like 'adding fuel to the fire'.
At the same time, the alkaline contained in tea will control the kidney's ability to reabsorb. If you drink tea immediately after drinking alcohol, the undigested toxins in the alcohol will seep into the kidneys, damaging kidney function.
People with constipation should not drink a lot of tea.
Tea contains a lot of acid that not only reduces intestinal contractions but also causes protein, peptides, iron, and metal ions to precipitate, making stools dry and causing constipation or making constipation worse for people who already have it.
It should be noted that the longer the tea leaves are steeped, the more tannins are released, which is more harmful for people with constipation.
Use 70-80% boiling water to steep the tea, do not cover.
Doing so can keep the good flavor of the tea, will not make the second and third water bland, and can also avoid high temperature destroying the beneficial ingredients in the tea.
Tea should not be drunk all at once.
There are people who drink tea and often drink it all at once before pouring more boiling water, which affects the flavor of the second or third cup.
A better way is: When the first water is about 1/3 left, add more boiling water. After drinking 2/3, add more boiling water to steep.
Tea should not be brewed many times.
Normally, you only need to steep it 3-4 times. The first time you steep it, the tea can dissolve 30% of the soluble substances in the tea, the second time it is 50%, the third time it is 10%, and by the fourth time it is only 5%.
As the proverb says: 'The first water is bitter, the second is nutritious, the third is pure, and the fourth is tasteless'. If a pot of tea is brewed many times, some harmful substances in the tea leaves will dissolve into the tea water, which is not good for health.
Hopefully with the above information you have the answer to the question "Can you drink fresh tea left overnight?". Use fresh tea properly to get the best health benefits.
