Green tea has been used in ancient Chinese medicine for many centuries to cure everything from migraines to depression. Its leaves are apparently richer in antioxidants than any other kinds of tea due to the manner in which they are processed. Green tea contains B vitamins, folate, manganese, potassium, magnesium, caffeine and other antioxidants, which are benefic for your health.
All types of tea are made from the Camellia sinensis herb using different methods. Fresh leaves from the plant are steamed to produce green tea, while other assortments of teas imply fermentation. Green tea is known to help with weight loss, lowering cholesterol, averting cardiovascular disease, and prevent cancer and even Alzheimer’s disease. But does it really?
There is no clear confirmation that sipping green tea protects you against various types of cancer. A research from 2009 involving 51 studies, on more than 1.6 million persons, tried to find a link between drinking green tea and cancers of the bowel, prostate, breast, mouth and lungs. Researchers concluded that the evidence between these two is weak and “highly contradictory”.
A current study developed in 2015 analyzed the cancer-combating effects of a compound which is found in green tea when mixed with a drug called Herceptin, used for treating stomach and breast cancer. The first batch of results were encouraging and trials are now being scheduled. But don’t take this as an official guidance to drink green tea while taking Herceptin.
Another inquiry is if green tea can help with weight loss. The compound preparations used for losing weight are extracts of green tea that contain a greater concentration of catechins (also found in red wine or broad beans) and the amount of caffeine results from a tea bag and boiling water. A well-conducted analysis from 2012 of 18 studies involving 1,945 individuals found no significant effect of weight loss from drinking green tea.
A research conducted in 2013 involving 11 studies and 821 people established that day-to-day consumption of green and black tea could help lower cholesterol and blood pressure. So, right now it’s 2 for 2. But can this drink go as far as preventing or delaying Alzheimer’s? Scientists are inclined to doubt it. In 2010, a laboratory study lead on animal cells found some antioxidants found in this type of tea can protect against nerve cell damage which is usually associated with dementia. But they don’t know for sure if the lab results can be applied to humans ergo, there are no conclusive findings that prove green tea has this power.
However, drinking green tea got on the trend wave so, you can enjoy it even without its magical qualities.
