Recently, the research team of Professor Wan from Anhui Agricultural University and Professor from China University of Science and Technology found that green tea can prevent and delay the formation of amyloid β protein in the brain of 5XFAD transgenic mice, reduce synaptic damage and improve learning and memory ability, so drinking green tea may prevent and delay Alzheimer's disease.

In recent years, the research on green tea has never stopped, and the efficacy of green tea has always attracted people's attention.

Tea polyphenols are antioxidant substances, and some people compare them to "powerful free radical scavengers", which can help the human body to scavenge harmful free radicals and resist aging, thus achieving the effect of preventing Alzheimer's disease.

Inflammation is one of the important factors leading to Alzheimer's disease. Inflammatory markers are usually significantly increased in the blood of patients with Alzheimer's disease. Tea polyphenols ingested by drinking tea can help us reduce brain inflammation, thus reducing the risk of Alzheimer's disease.

Studies have found that moderate intake of coffee, tea and other foods can help alleviate amnesia and prevent Alzheimer's disease. An American study shows that drinking tea regularly can delay the occurrence of Alzheimer's disease for 2-4 years.

Not everyone is suitable for drinking green tea, so who is not suitable for drinking green tea?

1, people with bad stomach should avoid drinking green tea. Green tea is unfermented tea, so there are many natural substances in tea, and the chlorophyll content is not much, which is very irritating to the stomach. Therefore, people with bad stomachs had better not drink green tea, and they can choose black tea to nourish their stomachs.

People with fever should not drink green tea. This is because green tea contains a lot of caffeine, and this caffeine in tea will not only raise the body temperature, but also reduce the efficacy.

3. Patients with urinary calculi should not drink green tea. Because urolithiasis patients generally have high calcium oxalate content, and oxalic acid contained in tea will form strong acid with calcium discharged with urine. If urolithiasis patients drink a lot of tea, their condition will be aggravated.

People with liver problems should not drink green tea. A large amount of caffeine and other substances in green tea are mostly metabolized by the liver after being absorbed by the human body. Drinking too much tea exceeds the metabolic capacity of the liver, which will damage the liver tissue and make the liver problem more serious.

People with bad stomach should not drink green tea. As we all know, green tea belongs to herbal tea, which makes people feel cool after drinking. That's because the content of tea polyphenols in green tea is high, which has a stimulating effect on the stomach. Especially some people like to drink strong tea. If your stomach is not very strong, I suggest drinking black tea instead of green tea, because black tea is warm and can warm your stomach and drive away cold.

Tea is not medicine, but it increases our interest in life, improves our resistance, and makes people less sick, at the same time, it adds a rare health value. To make drinking tea a daily habit, you must drink it every day, and feel and keep healthy by drinking tea.

A good life comes from a healthy beginning, a healthy beginning and professional media of health science!
