Green tea, derived from the Camellia Sinensis plant, shares its origin with black and oolong teas. However, the processing of green tea’s leaves is distinct from the others, as their oxidation is limited, giving the tea a unique taste and appearance. This lack of oxidation also ensures that green tea retains high levels of plant substances called catechins, believed to be the source of the tea’s medicinal properties. Green tea is a particularly rich source of the catechin epigallocatechin gallate (EGCG). Although catechins are also found in black and oolong teas, as well as other food items like apples, apricots, berries, and chocolate, green tea continues to be an excellent source.
Green Tea and Men’s Health
Recent meta-analyses have reported several benefits of green tea, particularly concerning men’s health. The beverage has been linked to risk reduction in breast, prostate, ovarian, and endometrial cancers, as well as lower levels of low-density lipoproteins and total cholesterol, both of which are significant risk factors for cardiovascular disease. Additionally, green tea has been found to aid in weight loss, a critical factor in conditions such as diabetes, arthritis, and heart disease.
** Impact of Green Tea on Cancer**
Extensive research has been conducted on green tea’s potential role in critical health issues. For instance, one extensive study involving 49,920 men concluded that those who drank five or more cups of green tea per day had a lower risk of developing advanced prostate cancer than those who consumed less than one cup per day. Additionally, catechins have been found to have a positive effect on men with pre-cancerous prostate lesions called prostate intraepithelial neoplasia (PIN). In a study involving 60 men with high-grade PINs, those who were given 200 mg of catechins per day had a significantly lower chance of developing prostate cancer than those who received a placebo.
Green Tea and Diabetes
While the relationship between green tea and diabetes requires further research, current data presents promising findings. In one study concerning diabetic rats, green tea was found to reduce hyperglycemia, prevent renal injury and autonomic dysfunction, thus decreasing potential risks and target organ damage due to diabetes.
Green Tea and Stroke Prevention
Consuming green tea has also been found to reduce the risk of patients suffering from various types of stroke. In a study published in the International Journal of Epidemiology, those who drank several cups of green tea every two to three days observed a reduction in the risk of stroke, cerebral infarction, and cerebral hemorrhage by 50% compared to those who didn’t.
Enjoying Green Tea Daily
Incorporating green tea into your daily routine is an easy, tasty way to improve your overall wellbeing. The beverage can be enjoyed hot or cold, with a slice of lemon, in a smoothie, or even in a slush. However, it is essential to note that not all green tea varieties are created equal. Japanese green tea varieties usually contain higher amounts of EGCG compared to their Chinese counterparts. One highly-rated Japanese green tea called Matcha provides about ten times the amount of EGCG as other green teas. If you’re short on time, green tea supplements can also be considered, but always consult a healthcare professional before beginning any supplement program.
