What are the health benefits of black tea? Eight reasons why black tea is good for a healthy life

1. Antioxidants and free radicals do you know why free radicals are harmful to you? Because they are highly reactive toxins that attack and destroy important living cells such as DNA, proteins, carbohydrates and lipids. This will do a lot of harm to your body. If you are interested, please read more about what happens when free radicals are not neutralized. Black tea contains a substance called polyphenols, which is a natural substance in tea. The polyphenols in tea are flavonoids, catechins, theaflavins and tannins. Don't worry about all the chemical names. The important thing is that these substances produce large amounts of antioxidants. All these naturally occurring antioxidants react with toxic free radicals to neutralize the damage to our bodies. Our bodies need at least 8000-11000 units a day, and drinking tea is the best way to do this without affecting our diet. Abstract: black tea is rich in antioxidants. Free radicals are highly active toxic substances that can damage your body. The antioxidants in tea help neutralize free radicals and improve your health. two。 Reducing the risk of diabetes or hyperglycemia is a major public health problem in the 21st century. With the increase of morbidity, eating habits and age, the number of patients with diabetes is increasing. The most common type of diabetes, called type 2 diabetes, occurs when the body is unable to regulate glucose levels. This can lead to heart disease, stroke, kidney damage, eye disease and nerve damage. A large number of studies have shown that black tea can increase insulin activity and help control blood sugar levels. The polyphenols in tea help prevent inflammation and type 2 diabetes. It is useful not only for healthy people trying to regulate blood sugar levels, but also for diabetics trying to control blood sugar levels. Summary: black tea helps to control blood sugar levels in healthy people and also helps to increase insulin activity in patients with diabetes. 3. Lower blood pressure-high blood pressure we all agree that high blood pressure is terrible. According to World Health Organization (WHO), high blood pressure causes nearly 7.5 million deaths worldwide. This accounts for about 12.8% of the total deaths. Hypertension can be caused by many factors, such as obesity, stress, alcoholism, smoking, genetic history and so on. The pressure of high blood pressure on blood vessels can cause all of the following symptoms. Heart attacks, stroke, kidney damage, blurred vision or loss of vision, dementia and memory loss have been studied worldwide to determine the effectiveness of black tea in reducing systolic and diastolic blood pressure. Most studies have shown that drinking black tea every day can significantly lower blood pressure. Abstract: hypertension is the leading cause of death worldwide, but it is preventable. A large number of studies have shown that drinking black tea every day for a period of time can reduce high blood pressure. 4. Black tea and cholesterol. We have two kinds of cholesterol in our bodies. One is LDL (low density lipoprotein) cholesterol, the other is HDL (high density lipoprotein) cholesterol. High density lipoprotein cholesterol is classified as "good" and low density lipoprotein is classified as "bad" because LDL cholesterol can cause stroke. When you have too much LDL, it deposits on the walls of blood vessels and arteries. This can prevent blood from flowing from the heart to your organs, leading to a heart attack. Studies have also shown that black tea can reduce harmful levels of low-density lipoprotein cholesterol. One study showed that the subjects' low-density lipoprotein cholesterol decreased by 7.5%. According to the findings, this is important because it reduces the risk of coronary heart disease. Although more research is needed to reach a consensus in the medical community, it is important to understand this. Abstract: low density lipoprotein (LDL) cholesterol can cause vasoconstriction, which can lead to heart attack. Black tea can reduce harmful levels of low-density lipoprotein, but more evidence is needed to gain general recognition.

5. Cancer and black tea have you heard the different terms of black tea and cancer? We have heard a lot about this, and the medical profession and experts have different opinions on this. As a result, it is difficult to reach a consensus. It is important to see what can be found in black tea to help reduce the risk of cancer. Antioxidants such as polyphenols have been shown to inhibit tumor growth and protect the skin from ultraviolet rays, which can cause skin cancer. Many studies support this view, but at the same time, the medical community believes that more research is needed. The conclusion that black tea can reduce the risk of cancer is not widely accepted. Although many studies have shown that the antioxidant properties of tea can reduce the risk of disease. 6. Black tea contains caffeine, but less than coffee. The last thing people know is that black tea contains caffeine in addition to antioxidants. On the other hand, coffee contains twice as much caffeine as black tea. Black tea contains an average of 47 milligrams of caffeine per 8 ounces. The amount depends on several factors, such as the type of black tea, brewing time and temperature. Most importantly, we should know how to check the quality of tea, because there are many cheap teas. It's always good to ask about the chemical composition of tea to make sure you're buying high-quality tea. If you want to know the difference between coffee and tea, you can read the opposite cup: tea has an obvious advantage over coffee? Caffeine is a natural stimulant that helps fight fatigue. According to some studies, it can also reduce the risk of liver, throat and oral cancer. Although many people in the medical community are divided on this and advocate more research. Medium to high doses of caffeine can lead to tension, irritability, increased heart rate, and even insomnia. Because of this, it is important to pay attention to your daily caffeine intake. Black tea contains an average of 47 milligrams of caffeine per 8 ounces, about half that of coffee. Caffeine is a natural stimulant and also helps reduce the risk of certain cancers. Side effects of caffeine include nervousness, irritability, increased heart rate and insomnia. 7. Relieve stress and feel relaxed after a long day, if you are looking for something to relax yourself, then black tea can help you. Black tea contains a substance called l-theanine, which is naturally found in tea trees and can help you relax. Theanine is an amino acid that is not produced by the human body, but it is abundant in green and black tea. Scientific evidence suggests that l-theanine intake lowers heart rate, which helps cope with stress. Abstract: theanine is a natural amino acid compound in tea. There is evidence that it can relieve stress by lowering the heart rate. 8. Increased attention and alertness of l-theanine is also a contributing factor. It has been found to be a factor in high-level cognitive activity and has been shown to interact with caffeine to enhance cognitive activity. More research is needed to reach generally accepted conclusions about the combined effect of caffeine and l-theanine. We can be sure that drinking tea containing l-theanine every day increases brain activity and helps us stay focused throughout the day. Summary: the l-theanine in black tea helps improve your cognitive ability and helps you stay focused throughout the day.
