Sometimes when you eat too much and you want to eat something to scrape oil
I think drinking tea can remove oil and reduce fat and clean the intestines
Want to know if drinking tea can really "scrape oil"?
01
Drinking tea can absorb fat
Inhibit fat digestion and absorption
The so-called scraping oil generally refers to cleaning the intestines, adsorbing and degrading excess oil in the body, and expelling it from the body.
The tea polyphenols, dietary fiber and other ingredients in
tea can adsorb and emulsify fat, which is conducive to the digestion of fat, but at the same time it can also inhibit the activity of lipase in the digestive fluid, making it ineffective and unable to digest fat. In this case, tea fully plays the role of "relieving greasy and "scraping oil".
Experts remind : "scraping oil" is actually a "anti-nutritional effect" and is not conducive to the digestion, absorption and utilization of nutrients in the substance. This is for some people who want to supplement nutrition or are already malnourished, intake of large amounts of tea polyphenols is an unfavorable to the body. It will not only cause nutritional loss, but may also cause physical discomfort for specific groups (side effects).
Generally, drink 12 grams of tea a day, brew it in 3 to 4 times. Except for sensitive people, others can drink 6 to 7 cups.

Drink tea for a long time The risk of cardiovascular disease is reduced by 8%
A study of the Journal of the American Heart Association (JAHA) found that drinking tea can help reduce the risk of cardiovascular disease.
The study analyzed the relationship between changes in high-density lipoprotein cholesterol (HDL-C) levels in the blood of more than 80,000 Chinese people and drinking tea, and followed up for 6 years. The results showed that the level of HDL-C for those who persist in drinking tea for a long time decreased more slowly, and the risk of cardiovascular disease was reduced by 8%. HDL-C is a "good cholesterol", which corresponds to "bad cholesterol". ——LDL-C. LDL-C is prone to deposit on the blood vessel wall and causes atherosclerosis, while HDL-C is the opposite and has a protective effect on the blood vessels.
In addition to paying attention to the levels of HDL-C, the researchers also collected the levels of total cholesterol (TC) and triglycerides (TG) of volunteers to calculate the ratios of TC/HDL-C and TG/HDL-C. The smaller the ratio of TC/HDL-C, it means that the larger the proportion of HDL-C in TC, the smaller the proportion of LDL-C, and the heart blood The lower the risk of disease. TG/HDL-C is also similar.
In fact, this is the effect of tea polyphenols. Tea polyphenols can be antioxidant, anti-inflammatory , and can also change the viscosity of the blood, reduce blood lipids , make blood vessel elasticity better, prevent microvascular rupture, and long-term consumption of will make the heart and blood vessels healthier, lower blood lipids, and prevent cardiovascular diseases .
How to drink tea to benefit cardiovascular?
green tea has a high content of tea polyphenols, which can reduce the risk of cardiovascular and cerebrovascular diseases in women slightly more; oolong tea will reduce the risk of cardiovascular and cerebrovascular diseases in men more; the elderly insist on drinking tea can indeed reduce the risk of cardiovascular and mortality by a large percentage.
To prevent cardiovascular and cerebrovascular diseases, drink at least 3 to 4 cups a day, 220 ml to 230 ml, and drink at least 4 to 5 times a week. Don’t act as much as you can, and drink tea in a small amount every day.
Note: Drinking tea cannot replace the effect of drugs, it is just a way to help our healthier body. If you have cardiovascular and cerebrovascular diseases, you still need to go to the hospital to find a specialist doctor for treatment.

Methods for Chinese people to prevent the three highs: Drink more tea
A review study recently published in the " Chinese Journal of Geriatric Medicine " pointed out that the specific benefits of drinking tea in adjusting the metabolism of the elderly are reflected in the following aspects.
1. Helps lose weight
Israel and Iran two clinical studies show that drinking green tea regularly can effectively reduce waist circumference and body mass index [BMI = weight (kg) ÷ height (meters) square].
A 12-week treatment for 92 obese patients in my country showed that patients who took green tea extract at large doses, especially women with central obesity, had significantly reduced weight and reduced waist circumference.
2. Reduce hypertension risk
Many factors will affect the correlation between tea drinking and blood pressure levels, such as the age of tea drinking, tea drinking habits, etc., but most evidence shows that drinking tea can reduce the risk of hypertension in the elderly.
Singapore A study conducted a 9.5-year follow-up of nearly 8,600 participants and found that the elderly who regularly drink green tea or black tea had relatively low blood pressure.
After 13 years of follow-up of more than 80,000 residents without a history of cardiovascular disease, Japanese researchers found that drinking 4 cups or more of green tea every day is beneficial to cardiovascular health. A study on
Brazilian also had similar results: intake of green tea can significantly reduce systolic blood pressure .
3. Improve dyslipidemia
cohort study on the relationship between drinking tea and blood lipids is relatively small, but the current research results show that drinking tea can improve dyslipidemia.
A study in my country found that taking tea polyphenols can reduce serum total cholesterol and high-density lipoprotein levels in elderly patients with hyperlipidemia.
A Japanese study showed that catechins can improve liver fat content in patients with non-alcoholic fatty liver.
A study published in the sub-job of Biomedical Center in a study that reduced LDL cholesterol after 73 overweight people were treated with supplemental green tea extract for 6 weeks.
There are also studies showing that people who drink more than 30 cups of tea per week and have a tea drinking life of more than 6 months have lower serum low LDL cholesterol levels and higher total cholesterol and high density lipoprotein levels.
4. May reduce the risk of hyperglycemia
Currently, the conclusions of the research on the risks of drinking tea and diabetes are different.
Study on supporting opinions:
A study on more than 10,000 Chinese people shows that drinking tea every day can reduce the risk of diabetes among the elderly by 23%.
A Japanese study conducted a five-year follow-up of more than 17,000 participants and found that people who drink at least 6 cups of green tea every day had a lower risk of diabetes.
A study in the United States conducted an average of 8.8 years of follow-up of nearly 40,000 adults and found that when drinking more than 4 cups of tea per day, the risk of hyperglycemia is relatively low.
does not support this view:
Another study by the above-mentioned American researchers showed that the intake of polyphenols substances has nothing to do with the risk of hyperglycemia. This condition may be due to the possibility that most diabetes diagnosis relies on participants’ self-statement and may be biased.

But it is best not to drink these 6 kinds of teas
1. Strong tea
Too strong tea can easily cause heart discomfort, because tea also contains caffeine , theophylline, etc.
At the same time, if you drink strong tea in large quantities, tannin will react with the iron element in the food, generating new substances that are difficult to dissolve, which will hinder the absorption of iron.
2. overnight tea
Because overnight tea is prone to breeding many bacteria and molds, if consumed, it may cause diarrhea. At the same time, the nutrients in the tea also undergo oxidation reaction, and the nutritional value of tea is also reduced.
3. Long-lasting tea
It is very similar to overnight tea. If you brew it for too long, not only will the taste worse, but the nutrients such as cellulose, amino acid in the tea will also be oxidized.
4. Moldy tea
Not all tea leaves are as old as possible. Once some tea leaves become moldy, the mold produced will also be harmful to people's health, which may lead to dizziness, diarrhea, and even necrosis of important organs.
5. Hot tea
People with gastrointestinal discomfort, such as reflux gastritis, heartburn, and pantothenic acid, should pay special attention to hot tea. We are usually used to using boiling water to make tea, but if the tea is too hot, do not drink it, otherwise it will cause scalds, and damage the oral and esophageal mucosa to induce gastrointestinal lesions.
6. Raw Tea
Raw Tea is a natural place after fresh tea leaves are picked and unfermented tea leaves. At this time, the tea nature of raw tea is relatively strong and has a strong stimulation to the gastrointestinal tract, which may cause stomachache . Therefore, if you have gastrointestinal weakness, you should use raw tea with caution.
If you really want to drink raw tea, don’t brew it directly. You can stir-fry it slowly over low heat to remove the green air. After a slight chestnut fragrance, you can drink it directly.
Drinking tea healthily
1. Dietary fiber and tea polyphenols have a certain adsorption ability, which can absorb oil in the intestines, while inhibiting fat digestion and absorption
2. Drinking tea for a long time can reduce the risk of cardiovascular disease by 8%
3. Methods suitable for Chinese people to prevent the three highs: drinking more tea
4. It is best not to drink these 6 kinds of tea: strong tea, overnight tea, long-term brewing tea, moldy tea, hot tea, raw tea
