What level of tea is considered strong tea

We all know that drinking tea is mainly based on light tea, and strong tea is bad for your health. However, when some tea friends make tea, they don't know how much tea is washed to be strong tea, and the amount of tea is not good. So, let's take a detailed look at what kind of tea is considered strong tea.

In general, strong tea is a tea that is too bitter and astringent because of too much tea leaves, and the tea soup is thick and opaque. The color is very thick and a bit turbid. After the tea is cold, a layer of tea oil will float on it. From the taste, it is very bitter to lose the light sweetness of tea.

Normal people should drink medium-concentration tea every day. It is not appropriate for ordinary people to drink too strong tea, because too strong tea contains a large amount of caffeine, which can stimulate nerves, especially drinking strong tea at night can cause insomnia.

The harm of strong tea

1. Drinking too much tea hurts the stomach

After drinking strong tea, it will dilute the gastric juice and reduce the concentration of gastric juice, so that the gastric juice cannot digest food normally, resulting in indigestion, bloating, abdominal pain and other symptoms. Those with poor stomach function may even cause duodenal ulcers.

2. Drinking too much tea often increases the burden on the heart

Drinking too much tea often will increase the burden on the cardiovascular and kidneys, and there may be symptoms of palpitation, chest tightness, frequent urination, urgency, and dizziness. Because the caffeine in strong tea can make the human heart beat faster, thereby increasing blood pressure, which in turn increases the burden on the heart and kidneys.

3. The higher the concentration of the elderly drinking tea, the greater the possibility of facing fractures

In 1991, Brown University and Boston University jointly studied and discovered a new problem of caffeine in strong tea, that is, strong tea will greatly increase the possibility of fractures in the elderly. Specific research results show that people who drink up to 5 cups of strong tea every day have a risk of pelvic fractures that are about 70% higher than those who drink light tea or do not drink tea, or even more than 80%. In other words, the higher the concentration of the elderly drinking tea, the greater the possibility of facing fractures.

4. Nervous breakdown

The habit of drinking strong tea before lunch break and before sleep can cause insomnia and affect the quality of sleep. The tea contains caffeine to excite the nerves, which can cause cerebral neurasthenia over time.

5. It is not advisable to drink strong tea on an empty stomach. Drinking a lot of strong tea, especially new tea, is easy to "drunken"

The caffeine contained in the tea strongly and powerfully stimulates the central nervous system and excites it, which in turn causes dizziness, palpitation, weakness in the hands and feet. The strong tea is relatively rich in caffeine, and it is more likely to cause tea drunk.

6, strong tea contains high fluoride, often drinking strong tea will damage the kidneys

Excessive fluoride retention in the kidney can cause damage to the kidney cortex and medullary tubules of the animal. The kidney is the main excretory organ of fluoride. When the body ingests excessive fluoride beyond the excretory capacity of the kidney, it will cause the accumulation of fluoride in the body, and the kidney fluoride will increase significantly.

7. Theophylline in strong tea damages kidney function through a series of actions

Theophylline in strong tea can quickly produce a diuretic effect through the kidneys, which will promote the unoxidized acetaldehyde to enter the kidneys prematurely. Acetaldehyde is highly toxic to the kidneys, which can damage the glomeruli and renal tubular cells, and harm kidney function.

8. Strong tea hangover is like adding oil to the fire, it will further damage the kidneys, stomach and heart

After the alcohol is absorbed by the digestive tract, it is first converted into acetaldehyde, then into acetic acid, and finally decomposed into water and carbon dioxide to be discharged from the body. Strong tea has a diuretic effect. It is excreted from the kidneys, and acetaldehyde can cause irritation to the kidneys, so drinking strong tea after drinking can harm the kidneys. Wine has a strong excitatory effect on the heart, and strong tea also has an exciting effect on the heart. Drinking strong tea after drinking will accelerate the heartbeat and increase the burden on the heart. Alcohol has a stimulating effect on the gastric mucosa, and strong tea can induce gastric acid secretion, further aggravating the stimulation on the gastric mucosa.

Therefore, you can't drink strong tea after drinking, and you can drink some honey water after drunk, and you can also drink some freshly squeezed fruit juices, such as citrus, apple, pear, watermelon, sugar cane, etc.

People who should not drink strong tea

(1) People with heart disease, high blood pressure, stomach problems, constipation, insomnia, neurasthenia, hyperthyroidism, and iron-deficiency anemia, drinking strong tea is equivalent to "adding snow to ice", which can cause gastrointestinal discomfort.

(2) Women who are breastfeeding, do not drink strong tea, because the polyphenols in the tea have an astringent effect on milk and affect milk secretion.

(3) Drinking a lot of strong tea will make the heart beat faster. This has the effect of inducing and aggravating the condition of coronary heart patients with tachycardia.

In summary, too much tea is poured, and the tea soup that is brewed is turbid, which is strong tea. Therefore, we should put less tea leaves when making tea to avoid making too much tea. If you often drink strong tea, it is very harmful to the body, so whether it is making tea or drinking tea, we have to be lighter.
