Scientific evidence supports many of the health benefits of green tea. However, it's important to note that it's not without its contraindications and side effects.

Have you ever wondered what happens to your body if you drink green tea every day? Green tea is a natural drink that has become popular around the world for its interesting medicinal properties. While it’s not a first-line treatment for disease, recent research does support its beneficial properties.

Unlike other types of tea, green tea doesn’t go through fermentation processes. As a result, it’s able to retain all of its antioxidants and polyphenols. For that reason, the consumption of green tea is linked with increased well-being, and the prevention of chronic diseases. Below, we’ll discuss its benefits in more detail.

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, many of its medicinal properties are attributed to its catechin content, especially epigallocatechin-3-gallate.

In addition, this same journal highlights that green tea is a source of:

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

Therefore, it’s not surprising that it’s considered a good supplement for improving the quality of one’s diet. 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.

If you’re suffering from any kind of health problem, the best thing to do is go to the doctor, who can explain all the available treatment options. If you drink green tea on a daily basis, you should let your attending doctor know, as it can interact with some kinds of medications. Now that we’ve made that clear, let’s go over the benefits of green tea in more detail.

Drinking green tea every day has a number of health benefits.

Scientific evidence supports the nutritional properties of green tea. Today, it is recognized for its contributions to health and well-being.

It can help with weight loss

The high concentration of polyphenols in green tea is connected to its ability to improve metabolism and reduce weight. These antioxidant substances increase energy expenditure and prevent the body from storing calories as fat. However, you should combine it with a healthy diet and physical exercise.

Favors the prevention of diabetes

According to a publication in Integrative Medicine Research, the antioxidants in this natural drink may help control blood glucose and prevent type 2 diabetes. In addition, drinking it every day after eating prevents insulin peaks and the storage of sugars in fat.

Protects cardiovascular health

A small cup of green tea every day can lower the risk of various kinds of cardiovascular disease, such as the accumulation of cholesterol, and circulatory disorders.

According to research published in Current Medicinal Chemistry, its antioxidant substances, specifically catechins, can lower the risk of blood clots, reduce clogging of the arteries, and help prevent the build-up of lipids in the blood.

As a result, its consumption is also associated with a lower risk of conditions such as heart attacks, strokes, thrombosis, and angina pectoris, among others.

Prevents cell degeneration

The antioxidants in green tea create a protective barrier against the harmful effects of cell degeneration. They also stimulate the activity of neurons. According to research published in the journal Molecules, green tea may help to prevent and treat neurodegenerative diseases, including cognitive dysfunction and memory loss.

Prevents kidney stones

A little green tea every day can help prevent renal calcification and kidney stones. In addition, according to a study published in the Journal of Urology, its extracts reduce the production and size of calcium oxalate sediments. These sediments settle in the kidneys and form kidney stones.

Prevents cavities

Catechins, a type of chemical antioxidant found in green tea, help fight the viruses and bacteria that cause throat infections, cavities, and other mouth conditions.

According to the findings of a study published in the Journal of Clinical and Diagnostic Research, green tea mouthwash was shown to be just as effective as chlorhexidine in fighting bacteria such as Streptococcus mutans.

Do you drink green tea everyday? Here are some of its contraindications

The beneficial properties of green tea are backed by research. However, it’s not without its contraindications and side effects. Its consumption shouldn’t exceed two cups a day, since it may have negative consequences such as:

  • Headaches
  • Nervousness
  • Diarrhea
  • Difficulty sleeping
  • Irritability
  • Increased heart rate
  • Dizziness

You should also avoid green tea if you’re on medication 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.

Responsible consumption of green tea is what determines whether or not it becomes beneficial for your health. Make sure you don’t exceed two cups of green tea per day and discover what it can do for your health.
