What is Oolong Tea?
Oolong tea is fragrant with a pleasant aroma and has a fruity flavor. 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 theprocess is halted as soon as the tea leaves start to change their color.
Oolong Tea Nutrition Facts
This tea is a natural gift that is rich in antioxidants. According to the USDA National Nutrient Database, oolong tea contains vital vitamins and minerals such as calcium, manganese, copper, carotin, selenium, potassium, and magnesium.Additionally, it contains niacinamide and other detoxifying alkaloids. It is developed in semi-fermented processing, which provides the tea with numerous compounds and adds even more valuable health benefits. Oolong tea also contains caffeine, theophylline, and theobromine (similar to caffeine), which on excessive consumption, may stimulate the nervous system.
Health Benefits of Oolong Tea
With so many health benefits, the inclusion of this tea in your diet is a great idea. Let’s have a look at the incredible 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 inThe 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.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.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
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.
Improves Mental Alertness
Health benefits of oolong tea include improved mental performance and alertness. Regular intake of caffeine-rich oolong tea may help in improving mental performance and maintaining alertness throughout the day.
It is a well-known fact that tea drinkers have a lower risk of getting skin cancer. Moreover, the polyphenolic compound in oolong tea promotes apoptosis in the case of cancerous cell growth in the stomach. This polyphenolic extract also acts as a chemo-preventive instrument against the development of other cancers as well. The compounds stifle the activation of cells, prevent the formation of N-nitroso compounds, and trap genotoxic agents before they can become effective, reveals a study published in the Journal of the National Cancer Institute.
Furthermore, drinking oolong tea helps to significantly lower the risk of developing ovarian cancer in women. The National Cancer Institute says that while the precise mechanism of why tea consumption helps prevent cancer is not established, the potent antioxidant polyphenols in tea have potential beneficial anti-cancer effects on human health.
According to scientific experiments, patients diagnosed with eczema can benefit from drinking 3 cups of oolong tea throughout the day. The beneficial results of this tea can be seen in less than a week and these patients will show remarkable improvement in recovering from skin problems. In a study published in the JAMA Network journal, 54% of test subjects were found to show positive, long-lasting results in terms of skin conditions after 6 months of daily intake of oolong tea.
Treats Atopic Dermatitis
Although the active mechanism has not been pinpointed exactly, many believe that the polyphenols present in oolong tea also work as anti-allergenic compounds, thereby relieving irritation and chronic skin problems like atopic dermatitis. Tea intake also brings down stress levels in the body, which helps soothe allergies.
Improves Bone Health
The antioxidants present in oolong tea protect teeth against decay, strengthen the bone structure, prevent, and promote normal, healthy growth of the human body. A number of studies have analyzed the long-term effects of drinking this tea, particularly on bone mineral density (BMD). They showed that people who consistently drank black or oolong tea for more than 10 years were less likely to lose their bone mineral density over that span of time. It is thought that some of the components in this tea actually stimulate the retention of minerals from other foods that we consume.
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.
Oolong Tea Side Effects
Despite all of these important benefits, it is important to remember that oolong tea tends to be high in caffeine, which is not the healthiest component of this beneficial beverage. Caffeine affects people differently. Some of the side effects of excess caffeine are:
- Irregular heartbeat
More serious conditions that can be exacerbated by too much caffeine intake are diabetes, heart conditions, anxiety disorders, irritable bowel syndrome, and high
Also, drinking too much oolong tea can actually sweep out excess calcium that your body is processing. For patients with osteoporosis, this can speed up bone degradation, even though other elements of oolong tea are helpful for this condition. It is best to use it as a preventive method for bone problems, rather than a treatment.
In other words, do drink unsweetened oolong tea daily because it might be the best kind of tea for improving your health, in addition to being a delicious and relaxing treat. That being said, be aware that caffeine is a powerful chemical, and monitor your body’s response to this change in your diet, just as you should with all new foods and nutritional sources.
