What Happens to Your Body if You Drink Green Tea Every Day?

December 5, 2019
Green tea is very beneficial for your body as long as you don't drink it in excess. The maximum recommended amount to get all of its benefits is two cups a day.

Green tea is a natural drink that has been part of traditional Chinese medicine for hundreds of years. Its consumption gradually spread throughout Asia over the centuries. These days, it’s cultivated in many other places around the world.

Unlike many other types of tea, this tea does n’t go through fermentation processes. Because of that, it’s able to keep practically all of its antioxidants and polyphenols. For that reason, it has several properties that can positively affect health. Do you know what happens when you drink green tea every day?

Benefits of drinking green tea every day

According to information published in Chinese Medicine, green tea has shown positive effects in the prevention of various diseases. Specifically, its medicinal properties are mostly attributed to its catechin content, especially epigallocatechin-3-gallate.

In addition, this same publication highlights that it’s a source of:

  • Proteins (15-20% dry weight)
  • Amino acids (1-4% dry weight)
  • Carbohydrates (5-7% dry weight)
  • Minerals and trace elements, (5% dry weight) such as calcium, magnesium, chromium, manganese, iron, copper, and zinc, among others.
  • Trace amounts of lipids (linoleic and α-linolenic acids)
  • Sterols (stigmasterol)
  • Vitamins (B, C, and E).

Therefore, it isn’t surprising that it’s also known as a “superfood.” However, it’s essential to clarify that it isn’t a substitute for medical treatments and doesn’t have miraculous properties. Its consumption should be considered a complement.

For any health problem, it’s essential to consult a professional. Similarly, it’s convenient to comment on your intention of trying green tea supplements, especially if you’re taking any medication. Now let’s review all the benefits of green tea in detail.

Contraindications of green tea

  • Headaches
  • Nervousness
  • Diarrhea
  • Difficulty sleeping
  • Irritability

Also, you should avoid green tea when you’re taking medications or drinking alcoholic beverages. This is due to its caffeine content. When you combine caffeine with other substances, it can cause undesired effects.

Experts recommend that pregnant women or women who are breastfeeding avoid drinking green tea. This is because it can cause adverse effects for the baby. Patients with high blood pressure, anemia, and digestive issues should also avoid drinking green tea or do so under medical supervision.
