Did you know that tea is the most popular beverage in the world, second to only water? Tea comes in many varieties from black tea, green tea, matcha tea to pu-erh tea and more. The hot beverage has been found to have many benefits for health. It can improve the health of the cardiovascular, digestive as well as immune system. It can also better bone health and cognitive abilities such as alertness and memory.
Several types of teas are anti-allergen as well as anti-cancer. Tea boasts antioxidants as well which can fight against damage-causing free radicals. However, some research works also link tea to negative effects on health. For instance, a latest research found that tea can cause esophageal cancer when served hotter than 140 degrees Fahrenheit. However, this has more to do with the temperature of the tea rather than the composition of tea.
Another research, which was published in 2013, discussed how excessive consumption of tea can cause a rare bone disease called skeletal fluorosis as it did so for a 47-year-old woman. Basically, tea contains fluoride, a mineral which shouldn’t be consumed in excess because while it is excreted out of the body, too much of it can form deposits on bones and make them brittle. However, water also contains fluoride. Moreover, some researches have linked tea with reduced osteoporosis risk.
Therefore, it cannot be said with confirmation that tea has a detrimental impact on bones. Either way, to stay on the safe side one must consume tea made from younger leaves than from older leaves as those tend to contain more fluoride content. Another reason why excess tea cannot be good for health is that tea contains caffeine. While some scientists say that coffee has a higher caffeine quantity, others are of the belief that tea has a higher caffeine content.
Caffeine in excess amounts is not good for health. It can increase blood pressure as well as the heart rate of a person. Moreover, once the ‘high’ of caffeine dies down, it can make one feel low. Too much caffeine can also cause anxiety and have a negative effect on blood sugar levels. This means excess caffeine is something diabetic people should avoid. Caffeine is also linked to calcium loss which, in turn, is associated to increased osteoporosis risk.
Caffeine can cause insomnia by awakening the senses when it is consumed just before bed. Some research also says that tea can cause prostate cancer. However, other studies show that green tea can take the risk of prostate cancer down while black tea has no relation with prostate cancer, good or bad. Since there is contradiction here as well, more research is needed to show tea consumption as the culprit behind prostate cancer.
To sum up, it can be said that the adverse side effects associated with tea intake are far less than the benefits that come with it. However, at the end of the day it is crucial to maintain moderation as too much of anything is harmful.
