The Health Benefits of Oolong Tea

From weight loss to heart health

If you are cold, tea will warm you; if you are too heated, it will cool you; if you are depressed, it will cheer you; if you are excited, it will calm you”.
William Ewart Gladstone

Oolong is Chinese tea, also known as “black dragon tea.” Like green or black tea, it originates from the camellia sinensis plant but is processed (i.e., oxidized and fermented) differently.

Oolong tea contains many healthy-boosting ingredients, including:

  • Fluoride
  • Magnesium
  • Manganese
  • Niacin
  • Potassium
  • Sodium
  • The Amoni Acid Theanine
  • Antioxidants (polyphenols) such as theaflavins, thearubigins, or EGCG

Oolong tea also contains Caffeine. The caffeine content is typically similar to green tea, but it can vary by type and region of origin.

Oolong tea can help to prevent diabetes

Diabetes has become an epidemic. According to a report issued by the Centers for Disease Control (CDC) in 2015, around 30.3 million Americans suffer from diabetes and have diabetes, 84.1 million have prediabetes.

Managing your blood sugar by preventing insulin resistance is one of the keys to prevent or improve this condition.

According to a study published in the Journal of Biological Chemistry, the consumption of EGCG can help to reduce insulin levels and thus to decrease the risk of type 2 diabetes. (1)

Oolong tea can help to improve heart health

Heart disease is one of the major causes of death worldwide. The consumption of Oolong tea can help you to improve your cholesterol profile, aka increasing the high-density lipoprotein (HDL) cholesterol, while lowering your low-density lipoprotein (LDL). This can prevent plaque buildup in your arteries and thus decrease your risk of cardiovascular diseases.

Apart from that, a Japanese study suggests that the daily consumption of Oolong tea can lower blood pressure levels, which is another risk factor for heart disease. (2)

“As much as you can eat healthily, it’s also important to drink healthily too. Tea is very healing.”
Kristin Chenoweth

Oolong tea can support weight loss

Research suggests that caffeine and polyphenols found in Oolong tea can help you to lose weight and burn fat. Participants of a 6-week study that consumed 8 grams of Oolong tea per day lost up to 3 kg. (3)

The participants of a study published in the Official Journal of the International Obesity Association increased their daily energy expenditure by 4.8%, which equates to 96 calories if you consume 2000 calories per day. (4)

Oolong tea contains an amino acid called l-theanine. L- theanine can help you to relax by increasing the neurotransmitters serotonin, GABA, and dopamine.

Oolong tea can help to prevent certain types of cancer

Oxidative stress is an imbalance between free radicals and antioxidants in your body and can cause many health conditions including cancer.
