The Health Benefits Of Tea

Numerous health benefits have been attributed to tea since time immemorial. In folk medicine, the health benefits of tea were already recognized 5000 years ago and it was used as a treatment for infectious diseases, colds, and also as an aid to the digestive and nervous systems.

Upon the expansion of scientific research in this field, more and more facts have accumulated testifying to the connection between regular tea consumption and lower chances of suffering from a wide variety of diseases, including cancer and cardiovascular disease.

Likewise, when drunk without adding any sugar, honey or milk, tea has no calories and simultaneously serves as a crucial component for maintaining the balance of body liquids.

Research Into The Health Benefits Of Tea

  • umerous studies show that tea leaves contain a high amount of polyphenols, which are a type of antioxidant, and that regular consumption of about five cups of tea per day contributes to keeping a high level of them in the bloodstream. The antioxidants work to neutralize free radicals. The free radicals are oxidizing molecules which naturally and harmlessly exist within the human body. However, they accumulate as a result of physiological processes such as metabolism, and are furthermore found in environmental factors such as polluted air, poisonous waste and cigarette smoke.
    The accumulated free radicals are an encumbrance upon the immune system as they attack the body tissues and harm cells thus leading to the development of chronic diseases and they are also linked to the aging processes.
  • A study led in Japan in which 9,000 women participated, shows that women who drank less than 5 cups of tea per day were twice as prone to suffer strokes. The phenols, found in the tea, prevent the oxidization of the cholesterol, which may cause damage to the blood vessels.
