The weather has just turned cooler recently, and autumn/winter is also a very suitable season for drinking black tea.
So this article will let you know about the benefits of drinking black tea regularly and the side effects of drinking black tea every day. It will also help you sort out which people are not suitable for drinking black tea frequently or for a long time.
6 Major Benefits of Drinking Black Tea
Do you drink black tea every day or often? According to surveys, black tea accounts for 75% of the world’s tea industry sales , which shows everyone’s love for black tea.
Black tea is also an indispensable main tea product in many cultures. Because there is an additional fermentation process in the production process , it has more shelf life and flavor, both in terms of storage time and flavor.
In this autumn/winter, hot drinks like black tea are the favorite choice for everyone, so let’s take a look at the benefits and effects of drinking black tea!
1. Anti-Cancer, Anti-aging and Antioxidant
The National Cancer Research Institute of the United States and Taiwan both point out:
Black tea contains a variety of nutrients. The ” polyphenols ” in it have antioxidant effects and can resist the damage of free radicals to cells. Therefore, they have a positive impact and benefit in inhibiting the growth of tumors.
2. Removes Greasiness, Helps Digestion and Increases Appetite
British people like to have black tea with their afternoon tea, and they often have black tea with their meals as a post-meal drink.
The reason is that black tea can remove the oily texture of meat in the mouth and relieve the sweetness caused by eating sweets.
Moreover, fermented black tea is relatively less irritating to the gastrointestinal tract, and after the polyphenols enter the human body, they will be oxidized into theaflavins and thearubigins (two main pigments that give black tea its color, taste, and aroma), which have the effect and benefit of helping digestion and thus promoting appetite.
3. Relax Blood Vessels and Reduce Cardiovascular Disease
According to American medical research, black tea can increase vasodilation (widening of blood vessels) in patients with heart disease from 6% to 10%, and for ordinary people, it can increase it to up to 13%.
A study in the “European Journal of Clinical Nutrition” also suggested that drinking black tea can help reduce the risk of arteriosclerosis (when arteries grow thick and stiff and restrict blood flow to organs and tissues in the body).
During the transition between autumn and winter, it is easy to catch a cold, and the cold weather can also cause vasoconstriction to be uneven, so drinking black tea is perfect for warming up. Elderly people can also reduce the chance of winter stroke due to imbalanced vasoconstriction (narrowing of blood vessels).
4. Anti-Metal Alkaloids and Anti-Inflammation
The polyphenols in black tea have anti-inflammatory effects, and experiments have found that catechins can bind to single-cell bacteria and inhibit and eliminate germs through protein coagulation and precipitation.
This is very happy news for modern people who have grown up with a lot of industrial pollution.
5. Refreshing, Diuretic and Promoting Metabolism
The caffeine and aromatic substances in black tea can increase renal blood flow and thereby expand renal capillaries. Therefore, it has a diuretic effect and helps to promote circulation and metabolism in the body.
The caffeine in black tea excites the nerve center by stimulating the cerebral cortex, which has a positive effect on refreshing the brain.
6. Protecting the Gastric Mucosa and Nourishing the Stomach
The oxidation products of tea polyphenols in black tea can promote human digestion, so drinking black tea in moderation can reduce inflammation and protect the gastric mucosa.
It is generally recommended that those with a sensitive stomach can add milk to drink together, which can reduce the irritation of the tea to the stomach.
* After the black tea is allowed to cool down, the effect of nourishing and warming the stomach will be affected, and black tea that has been left for too long will also lose a lot of nutrients. Therefore, it is not recommended for those who have this complaint to drink iced black tea or cold black tea.
