Here are some details of the different types of tea:

General benefits of red tea

Red tea is made by drying the tea leaves after picking them, and then subjecting them to fermentation, which gives the tea a stronger flavor and a darker color, and this tea contains the most caffeine, and there are many benefits of red tea because it contains many nutrients the mission.

It also contains many antioxidants, such as; A compound called Epigallocatechin gallate, Thearubigins, Theanine, and Theaflavin; Which is the most prominent compound available in red tea, and it forms a group of polyphenols that are formed during exposure to oxidation processes, and it contains 3 to 6% of the total polyphenols in tea.

These antioxidants and other compounds found in red tea can reduce inflammation in the body and the risk of chronic disease. Polyphenols also increase lipolysis and reduce fat accumulation by limiting the growth of fat cells.

General benefits of green tea

Green tea is made from the unoxidized leaves of the Camellia sinensis, and is more mature compared to white tea leaves, and these leaves may be withered before being subjected to fumigation, then rolled and dried.

One of the benefits of green tea for rumen and diet is that it contains many antioxidants, the most abundant of which are catechins; As it exceeds the rest of other teas by 30 to 42%, especially the compound Epigallocatechin gallate, and in fact, green tea is more beneficial in terms of its antioxidant content compared to red tea, and it also has properties that reduce inflammation, and the risk of cancer.

Green tea can be used for pregnant women, because it contains a small amount of caffeine compared to red tea, as one cup, or the equivalent of approximately 227 milliliters, contains between 20 to 45 milligrams of caffeine, whose amount in tea depends on the duration of fermentation, and the amount of tea used in its preparation.


General benefits of white tea

White tea became famous in the past decade, and it is considered the rarest type of tea, produced in small quantities, and it is known to be expensive, and it is made from closed buds of the tea plant and its immature leaves, and then these leaves are exposed to steam, thus inhibiting the activity of the polyphenol oxidase enzyme (In English: Polyphenol oxidase) in it, ends with drying, and these leaves retain a large amount of catechins because they are less subject to oxidation.

Several studies have indicated the beneficial effect of this tea on biological processes that have been altered by oxidative stress, and it may reduce the growth of bacteria, viruses, and fungi more than other teas.

White tea contains caffeine in greater quantities than green tea, but it is present in greater quantities in new buds and leaves than in old leaves and buds. In contrast, white tea does not contain tannins or tannins as found in red tea.

General benefits of Chinese tea

Tea Side Effects

Disadvantages of drinking tea in large quantities

Here are some of the harms that may result from drinking too much tea:

Decreased iron absorption

Tea is a rich source of tannins or tannins, which bind with iron in foods, which may reduce its absorption in the digestive system.

Increased feelings of anxiety, stress, and lack of sleep

Excessive consumption of caffeine in tea can cause feelings of stress and lack of sleep; As it reduces the production of the hormone melatonin, which causes lack of sleep, and if these symptoms are observed, drinking tea should be reduced, or the consumption of caffeine-free alternatives to tea.

Increased risk of heartburn

The relaxation of the muscle in the lower part of the esophagus increases due to the increased consumption of caffeine in tea. It also increases the production of acids in the stomach, and its reflux into the esophagus, which causes a feeling of heartburn.

Nausea, dizziness, and headache

Irritation in the tissues of the digestive system may occur in some people who suffer from allergies after consuming one to two cups of tea due to its content of tannins or tannins, and this causes the appearance of symptoms of nausea, stomach pain, and drinking tea in large quantities and continuously causes headaches. chronic, and large amounts of it may also cause dizziness; But this side effect is rare, and occurs only if tea is consumed in an amount ranging from 6 to 12 cups, which is equivalent to 1.4 to 2.8 liters.

Disadvantages of drinking tea on an empty stomach

There are no studies showing the harms of drinking tea on an empty stomach, but taking green tea extracts concentrated on an empty stomach leads to more damage than those caused by eating it after eating, according to a review published in the journal Drug Safety in 2008.

Disadvantages of drinking tea immediately after eating

Consuming tea with or immediately after food reduces the absorption of non-heme iron, but drinking it at least an hour after eating the food does not reduce iron absorption by the same amount, according to a small study published in The American Journal of Clinical Nutrition. 2017, and therefore the time of consumption of drinking tea is important to maintain iron levels, especially by those who suffer from iron deficiency.
