5) Type 2 Diabetes
Studies concerning the relationship between green tea and diabetes have been inconsistent. Some have shown a lower risk of developing type 2 diabetes for green tea drinkers than for those who consumed no tea, while other studies have found no association between tea consumption and diabetes at all.1
6) Weight Loss
Green tea may promote a small, non-significant weight loss in overweight and obese adults; however, since the weight lost in the studies were so minimal, it is unlikely that green tea is clinically important for weight loss.
7) Inflammatory Skin Diseases
A 2007 study concluded that green tea could hold promise as a new treatment for skin disorders such as psoriasis and dandruff. Researchers studied an animal model for inflammatory skin diseases, often characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells' life cycles.
8) Working Memory
Research published in the journal Psychopharmacology in 2014 suggests that green tea can enhance our brain's cognitive functions, particularly the working memory.7
The research team said their findings suggest that green tea could be promising in the treatment of cognitive impairments associated with neuropsychiatric disorders, such as dementia.
9) Alzheimer's disease and dementia
In a study published in 2011, researchers tested the effect of a component of green tea, CAGTE, after it had been digested, to see how it affected a key protein in Alzheimer's disease. The study showed that at high concentrations, CAGTE protected the cells from the toxic effects of the protein amyloid-beta.
The Alzheimer's Society commented that, "this study adds to previous research that suggests green tea might help to reduce the risk of Alzheimer's disease. However, the researchers used a far higher dose of the active green tea chemical than would ever be found in the human body. More research is needed to see whether green tea is protective at a much lower dose, and to understand the mechanism involved."
Researchers at the University of Michigan published results of a study in 2013 that showed a molecule in green tea may help prevent the misfolding of specific proteins in the brain.
Additionally, the results of a study published by the University of Missouri in 2015 concluded that green tea extract and exercise hindered the progress of Alzheimer's disease in mice. They hope that their comprehensive study of EGCG, a compound found in green tea, could eventually lead to treatments for Alzheimer's disease in humans.
Recent developments on the health benefits of green tea from MNT news
British researchers have scientifically proven that broccoli, turmeric, green tea and pomegranate help fight the most common cancer in men in the United States and the United Kingdom - prostate cancer.6
A study reveals how an active component of green tea disrupts the metabolism of cancer cells in pancreatic cancer, offering an explanation for its effect on reducing risk of cancer and slowing its progression. The researchers believe the discovery signals a new approach to studying cancer prevention.
A compound found in green tea could be an effective treatment for rheumatoid arthritis, according to the results of a new study published n the journal Arthritis and Rheumatology.
On the final page we look at the nutritional profile of green tea, the forms of green tea and precautions and risks associated with green tea.
