With the accelerated pace of modern life, more and more people are paying attention to health issues. Among them, hyperglycemia, as a common health problem, has attracted widespread attention. To control blood sugar levels, people have tried various methods, which include dietary modifications. In recent years, studies have found that some teas have the effect of lowering blood sugar, which is undoubtedly good news for the majority of tea lovers. This article will introduce in detail three kinds of teas with remarkable hypoglycemic effects, and analyze the knowledge points from three aspects to help you better understand the hypoglycemic effects of these teas.1. The relationship between tea and blood sugarBefore we can specifically lower our blood sugar, we need to understand the relationship between tea and blood sugar. Tea is rich in active ingredients such as tea polyphenols and catechins, which have certain antioxidant and anti-inflammatory effects and are beneficial to human health. In recent years, studies have found that certain components in tea also have the effect of lowering blood sugar. These ingredients can inhibit intestinal absorption of glucose and improve insulin sensitivity, which can help lower blood sugar levels.
Two or three kinds of tea with significant hypoglycemic effect
1. Green tea
Green tea is an unfermented tea leaf that retains more active ingredients such as tea polyphenols and catechins. Studies have shown that the catechins in green tea can inhibit the absorption of glucose in the gut and reduce blood sugar fluctuations. In addition, green tea also has the effect of improving insulin sensitivity, which helps to lower blood sugar levels. Therefore, drinking green tea in moderation can help control blood sugar.
2. Black tea
Black tea is a fermented tea leaf with a unique taste and aroma. Studies have found that components such as tea polyphenols and amino acids in black tea have the effect of lowering blood sugar. These ingredients can promote the secretion and utilization of insulin, improve insulin sensitivity, and thus help lower blood sugar levels. In addition, black tea also has the effect of improving the structure of intestinal flora, helping to maintain intestinal health and further promote the stability of blood sugar.
3. Oolong tea
Oolong tea is a semi-fermented tea that is somewhere between green and black tea. Studies have shown that ingredients such as tea polyphenols and caffeine in oolong tea have a blood sugar-lowering effect. These ingredients can inhibit the absorption of glucose in the intestines and reduce the rise in blood sugar. At the same time, oolong tea also has the effect of increasing metabolism and promoting lipolysis to help control weight and reduce the risk of blood sugar.
3. Precautions for drinking tea to lower blood sugar
Although drinking tea can help lower blood sugar, there are also a few things to be aware of:
Drink in moderation: Caffeine and other ingredients in tea have a certain irritation, and excessive consumption may lead to insomnia, heart palpitations and other adverse reactions. Therefore, it is recommended to control the amount of tea consumed at 3-5 cups per day.
Choose the right tea: Different kinds of tea have different hypoglycemic effects, it is recommended to choose the right tea according to your own situation. For example, green tea is suitable for daily drinking, black tea is suitable for people with indigestion and obesity, and oolong tea is suitable for people who need to refresh their minds.
Avoid drinking tea on an empty stomach: Drinking tea on an empty stomach may irritate the gastric mucosa, resulting in stomach pain, bloating and other uncomfortable symptoms. It is recommended to drink tea about half an hour to an hour after a meal to help promote digestion and lower blood sugar.
Pay attention to the way you drink your tea: It is recommended to drink tea by brewing and avoid using too many tea leaves or steeping for a long time, so as not to cause excessive release of caffeine and other components in the tea.
Fourth, the scientific basis for drinking tea to lower blood sugar
At present, a large number of studies have confirmed that tea has the effect of lowering blood sugar. These studies are mainly carried out in the following aspects:
The relationship between tea composition and blood glucose metabolism: Studies have found that tea polyphenols, catechins and other components in tea can inhibit intestinal absorption of glucose, improve insulin sensitivity, and thus help lower blood sugar levels. In addition, these ingredients also have antioxidant, anti-inflammatory and other effects, which help to improve insulin resistance and reduce the burden on pancreatic islets.
The effect of tea on the human endocrine system: Some components in tea can regulate the body's endocrine system and promote the secretion and utilization of insulin. Insulin is a hormone that lowers blood sugar, and its increased sensitivity helps lower blood sugar levels. Therefore, drinking tea can improve the phenomenon of insulin resistance to a certain extent and reduce the risk of chronic diseases such as diabetes.
Effect of tea on human intestinal flora: Studies have found that certain components in tea can improve the structure of the intestinal flora and promote the growth and reproduction of beneficial bacteria. The intestinal flora is closely related to human health, and its balance is of great significance for maintaining blood sugar stability. Therefore, drinking tea helps to maintain intestinal health and further promote the stability of blood sugar.
5. Summary
As a traditional food culture, tea drinking not only has a unique taste and aroma, but also has certain health benefits. Studies have found that teas such as green tea, black tea, and oolong tea have the effect of lowering blood sugar, which is undoubtedly good news for the majority of tea lovers. However, when enjoying the health benefits of tea drinking, we also need to pay attention to things such as drinking it in moderation, choosing the right tea leaves, and avoiding drinking tea on an empty stomach. At the same time, we should also realize that drinking tea to reduce blood sugar is not a panacea, and it also needs to be combined with other healthy lifestyles such as reasonable diet and moderate exercise to maintain blood sugar stability.
Finally, we hope that the majority of tea lovers can pay more attention to their own health in the process of enjoying tea drinking, choose tea that suits them and drink them reasonably. At the same time, we also hope that scientists can continue to study the health benefits and mechanism of action of tea, and contribute more wisdom and strength to the cause of human health.
