Black tea, the most popular type of tea worldwide, has a variety of health benefits, such as strengthening the immune system, refreshing the mind, and improving digestion. Drinking black tea regularly can indeed have a good health effect.
However, you also need to pay attention to the way you drink tea. Not everyone is suitable for frequent drinking of black tea. Next, let’s talk about who should not drink black tea often and see if you are among them?
1. Children
Children are generally not suitable to drink black tea regularly. This is mainly because the caffeine in black tea is more sensitive to children and may cause discomfort such as excitement, insomnia, and rapid heartbeat.
In addition, the tea polyphenols in black tea may affect the absorption of iron, and children are in the growth and development stage, so adequate iron intake is particularly important. Long-term consumption of large amounts of black tea may also cause tea stains, affecting oral health and posing a threat to the beauty of children’s teeth.
2. Pregnant and lactating women
Pregnant and breastfeeding women should be extra careful with their black tea intake. These two stages require special attention to diet and drink choices, because the health of the woman is directly related to the health of the fetus and baby. Reasons why you should be cautious when drinking black tea include:
First of all, caffeine is metabolized slowly in pregnant and lactating women, and excessive intake may lead to premature birth or poor sleep in babies.
Secondly, the polyphenols in black tea may interfere with the absorption of iron, and pregnant women need enough iron to support fetal development. Additionally, pregnant and breastfeeding women generally need more antioxidants, but the polyphenols in black tea may have adverse effects on antioxidants.
3. Patients with high blood pressure
The caffeine in black tea may adversely affect people with high blood pressure. Caffeine can cause blood pressure to rise, which may worsen symptoms in people who already have high blood pressure.
Compounds in black tea may interact with blood pressure medications, making them less effective. At the same time, patients with high blood pressure need to control their fluid intake. Excessive consumption of black tea may lead to fluid retention and aggravate blood pressure problems.
4. Digestive system problems
For some people, especially those who suffer from digestive problems such as gastric ulcers, acid reflux, and esophageal inflammation, regular consumption of black tea may be detrimental. Caffeine and tea polyphenols may stimulate gastric acid secretion, causing stomach discomfort and increasing the risk of stomach pain or inflammation.
In addition, the tea polyphenols in black tea may also have a stimulating effect on the gastric mucosa and aggravate gastric pain or inflammation. Theophylline may have adverse effects on the esophageal mucosa and aggravate the symptoms of esophageal diseases.
5. Anemia patients
Anemia patients should not drink black tea frequently because the polyphenols in black tea may interfere with the absorption of iron, which is an urgently needed nutrient for anemia patients.
Iron is a key nutrient for patients with anemia, but the polyphenols in black tea may reduce the absorption of non-heme iron, thereby aggravating the anemia problem. If an anemic patient requires iron supplements, they should be taken outside of drinking black tea to ensure adequate iron absorption.
6. Drug interactions
Compounds in black tea may interact with certain medications, reducing or enhancing their effectiveness. First of all, the vitamin K in black tea may interfere with the efficacy of anticoagulant drugs. People who are taking such drugs should avoid drinking large amounts of black tea.
Secondly, compounds in black tea may affect the absorption of certain antibiotics, potentially reducing their effectiveness.
7. Oral health issues
Long-term consumption of large amounts of black tea may have adverse effects on oral health. The pigments and tannic acid in black tea may cause tea stains, turn teeth yellow, and affect the appearance of the oral cavity. Additionally, excessive consumption of hot black tea may lead to gum problems such as gum inflammation.
In conclusion, although black tea has many health benefits, frequent consumption is not suitable for everyone. Children, pregnant and breastfeeding women, those with high blood pressure, those with digestive problems, those with anemia, those taking medications, and those who are concerned about their oral health should all choose their black tea intake carefully.
Before consuming black tea, it is best to seek the advice of a physician or healthcare professional to ensure it meets individual health needs.
Only if you understand your own situation and choose carefully can black tea bring health benefits to people without causing discomfort and risks. Everyone should pay attention to this point. In fact, by extension, this is true for all teas. You should choose the appropriate tea according to your own situation and tea characteristics.
