Antioxidants comprise vitamins, minerals and enzymes that seem to help the body to protect itself against the formation of free radicals, small chemical particles that tend to damage the cells and destroy blood vessels walls. It seems that these free radicals can attack the immune system and stimulate the onset of infections and cancers. It is also believed that certain aging signs are caused by their presence in the body. Antioxidants such as those found in green tea act as free radical neutralizers and reduce the health risks that they represent.
The human body produces its own antioxidants in the form of enzymes. As well, antioxidants are also found in foods; excellent sources are fruit and vegetables as well as foods containing vitamins A, C, E, and selenium. Certain herbs, plants, and other natural products are thought to contain antioxidants. For example, green tea.
It has been recognized that green tea has protective effects against cancer. However, to notice a decrease in the risk of breast cancer, one must drink 1,2 l every day. Such a quantity would also help in reducing oesophagus, pancreatic and bladder cancer.
Tea contains 10 to 15 mg of caffeine. When drank in large quantity and because of its caffeine content, it could cause headaches, anxiety, nervousness, insomnia, palpitations, trembling, and gastric acidity problems. Therefore, it is not advised to drink green tea in large amount if you suffer from heart problems, high blood pressure, thyroid problems, or mental disorders. Green tea’s undesirable side effects may be more severe in children than adults.
Green tea tannins can be helpful in certain cases of chronic diarrhea, as they more or less cause constipation.
Moreover, green tea may be effective in:
Improving the brain’s performance
Lowering cholesterol and triglycerides
Increasing water elimination by the body
It might be used as a diuretic and combined with other products to ease weight loss. On the other hand, this weight loss is often caused by the diuretic effect of green tea and there is no elimination of fat, rather simple body dehydration. This type of weight loss offers no long-term advantage. Talk to your pharmacist before taking such products.
