Oolong tea has many amazing benefits as it helps to boost metabolism, aids in weight loss, control type 2 diabetes, treats heart diseases, prevents cancer, and improves brain, bone, and dental health. It also has the ability to treat disorders and high cholesterol levels while providing vital and robust skin.
What is Oolong Tea?
Oolong tea is fragrant with a pleasant aroma and has a fruity flavour. Despite its caffeine content, it is still a relaxing drink. The health benefits of oolong tea are doubled because of the combined qualities of black tea and green tea. According to the Tea Association of the United States, this tea falls somewhere between green and black teas, as its leaves are partially oxidized. There are numerous kinds of tea in this world, but oolong tea is one of the most beneficial.
The origin of oolong tea dates back almost 400 years when it found wide usage in China. It is a semi-green fermented tea, but the process is halted as soon as the tea leaves start to change their colour.
Health Benefits of Oolong Tea
Helps in Weight Loss
The polyphenolic compound found in oolong tea is positively linked to controlling the metabolism of fat in the body and reducing obesity. In a 2009 study published in The Chinese Journal of Integrative Medicine, 102 overweight or obese people who drank four cups of oolong tea (the brew from 4 2 gram tea bags) lost weight. 22 percent lost more than 3 kgs of weight. Moreover, all participants show a remarkable decrease in their total cholesterol and levels.
Additionally, a study published in the International Journal of Obesity and Related Metabolic Disorders said that laboratory tests performed on mice showed that intake of oolong tea activates certain enzymes and improves the functions of fat cells. In another study, mice that were given polyphenols in addition to a high-fat and high-sugar diet still showed a decline in overall body weight and fat index. Studies show that the caffeine content is an active ingredient for weight loss, and it now appears that the weight loss is further accelerated due to the polyphenols present in this tea.
Oolong tea is used as an herbal brew for treating type-2 diabetic disorders and as an addition to other supplementary drugs for treating the disease. It regulates the amount of blood sugar and insulin in the bloodstream, so the dangerous dips and spikes in blood sugar that can be disastrous for diabetics are reduced. Dr. Beverly Clevidence, the research leader at the USDA-funded Food Components and Health Laboratory in Beltsville, Maryland, in her study reveals that when combined with regular hyperglycemic drugs, oolong tea further balanced the blood sugar levels and prevented sudden drops in almost all of the test subjects.
Removes Harmful Free Radicals
The polyphenolic compound in oolong tea is also responsible for the removal of free radicals in our body as it functions as an antioxidant. A study by Dr. Guoyao Wu, distinguished professor, Texas A&M University, US, establishes that the tea phenols help in scavenging free radicals.Therefore, consuming daily doses of oolong tea can help people against the potential harm that these free-moving cells often pose to the body, including cancer, , stroke, rheumatoid arthritis, neurodegeneration, and diabetes.
In a detailed study conducted at the Osaka Institute for Health Care Science in Japan, the experimental mice in which oolong tea was ingested, showed a remarkable improvement in the stress levels by 10 to 18 %.The natural polyphenols in oolong tea were cited as the main cause of it being a stress-buster. Also, the L-theanine found in tea leaves is an amino acid that blocks L-glutamic acid to glutamate receptors in the brain. This normally causes cortical neuron excitement, which leads to an increased cognitive activity and neural stress responses. Since this amino acid binds to those sites, excitation doesn’t occur, and stress decreases because you are able to keep your mind at rest.
