The wrong time to drink tea

After dinner, cups of tea or mellow espresso coffee are a great enjoyment of life for many people. Some people even think that it will not only clean the mouth but also help digestion. In fact, drinking tea immediately after a meal is detrimental to health, and it also lays a hidden danger for anemia in the future.

Huo Junsheng, director of the Food Science and Technology Division of the National Institute of Nutrition and Food Safety at the National Center for Disease Control and Prevention, said in an interview with a reporter from the “Life Times”: “Immediately drink tea after a meal. A lot of water enters the stomach that is digesting food, diluting the secretion of the stomach. Digestive fluids, which affect the stomach's digestion of food, in addition, tea contains a lot of tannic acid, tea after a meal, will make the future digestive protein in the stomach and tannic acid into a non-digestible coagulation material , And affect the digestion and absorption of protein. More importantly, tea interferes with the body's absorption of iron. After drinking a tea with 15 grams of dried tea, the absorption of iron in food will be reduced by 50%. In the long run, it will affect Human digestive function may even cause iron deficiency anemia."

Nowadays, there are many people who like to have some tea after eating, thinking that they can eliminate it. In fact, this is also bad for health. Director Huo told reporters: "Because a large amount of tannic acid in tea will combine with protein to form tannic acid protein, this material has astringent effect, weakening intestinal peristalsis and prolonging the residence time of food residues in the intestine, resulting in dry stools. ."

Director Hu stressed that in order to avoid the symptoms of anemia, it is appropriate to drink coffee or tea after emptying the stomach for about 1-2 hours after a meal. Usually, iron-rich foods such as green leafy vegetables, red beans, and pork liver can be consumed. To avoid the lack of hemoglobin.

He suggested that it is best to drink black tea at night. Because green tea belongs to non-fermented tea, the content of tea polyphenols is relatively high and the irritating effect is strong. Black tea is a fully fermented tea and is weakly irritating. Tea should not be too thick. Fasting tea is easy to inhibit the secretion of gastric juice, impede digestion, and can even cause heart palpitations, headaches and other "tea drunk" phenomenon.

Blood System:
Blood system is also called circulatory system.
For the treatment of diseases of the circulatory system:
According to the American Heart Association, cardiovascular disease is the leading cause of death in the United States. Because of its vastness and critical nature, it is one of the systems of the body most prone to disease.

One of the most common diseases of the circulatory system is arteriosclerosis, in which the fatty deposits in the arteries causes the walls to stiffen and thicken the walls. According to the Mayo Clinic, the causes are a buildup of fat, cholesterol and other material in the artery walls. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke.

Stroke involves blockage of the blood vessels to the brain and is another major condition of the circulatory system, according to Mitchell Weinberg of the North Shore-LIJ Health System. [Risk factors include smoking, diabetes and high cholesterol," he noted.

Another circulatory disease, hypertension - commonly called high blood pressure - causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure, the NLM noted.

An aortic aneurysm occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions, according to Weinberg.

Peripheral arterial disease (also known as PAD) typically involves areas of narrowing or blockage within an artery, according to Jay Radhakrishnan, an interventional radiologist in Houston, Texas. In addition, chronic venous insufficiency (also known as CVI) involves areas reflux (or backward flow) within the superficial veins of the lower extremities.

PAD is diagnosed with noninvasive testing including ultrasound, CT scan, and/or MRI. Ultrasound is the least expensive of these methods, but also gives the least amount of detail, as CT and MRI show a much higher degree of anatomic detail when identifying areas of narrowing/blockage within an artery. CVI is diagnosed with ultrasound as the venous reflux can be measured accurately by ultrasound, which ultimately guides treatment.
